Version 1.1

This handbook provides guidance and a minimum set of expectations for Oasis Midstream Services (OMS) employees and contractors regarding contractor work performed for OMS. As the contractor, you are required to follow the policies and procedures established by the contractor’s company in addition to any of Oasis site-specific policies. This handbook is intended to supplement, not replace, the contractor’s company safety program, which the contractor is required to implement. In the event of a conflict between this handbook and the contractor’s company safety program, the more stringent rule shall apply. The contractor company’s contract with OMS may be canceled, or an individual may be asked to leave OMS owned property if the contents of this guideline are not followed.

1.1 Excellence through Teamwork

Environmental, health, safety, and

production goals cannot be reached

by operational groups operating

independently. This is true for OMS as

well as our contractors. While performing

work for OMS, contractors will be

exposed to hazards as well as operational

challenges and will be expected to

recognize, manage, and effectively solve

and mitigate these obstacles. This is

critical for our business to succeed.

1.2 How to Use this Guidebook

The intent of this handbook is to

provide guidance to our contractors

and employees regarding Oasis’s

expectations of its contractor workforce.

Included is mapping information,

operational specifications, DOT and

other federal regulations, manufacturer

requirements and other documents.

1.3 How to Use the Contractor Handbook

All of Oasis’s contractors should have

a copy of this handbook accessible to

them. The contents of this handbook

should be reviewed, discussed, and

understood by contract personnel

before any work is performed for

Oasis. If an HSE issue arises that is

not addressed in the handbook or by

the contractor’s own safety program,

you must ask for guidance from the

contractor representative or an Oasis

representative.

1.4 How to Use the Inspector Handbook

Inspectors and supervisors provide

services that require additional

information necessary for the quality

assurance and control of various

projects. Operational Specifications,

map information, and other historical

project scopes will be accessible to Oasis

employee or contractor inspectors.

The value and effectiveness of these

programs must be audited on an

annual basis, reports compiled, and

findings recorded for ongoing program

development.

Contractor Management

DOT standards require that contractors

performing work on behalf of any

pipeline regulated by the DOT, complete

operator qualification programs and be

enrolled in DOT regulated drug & alcohol

consortiums. OMS utilizes Veriforce as

their approved service provider and

standardization group for contractors

performing construction, maintenance,

or emergency response on DOT

regulated pipelines.

3.1 Veriforce

Drug and Alcohol Programs

100% Consortium Participation

All personnel who take part in the

construction of a DOT regulated pipeline;

inspectors, foreman, supervisors,

laborers, truck drivers, must be enrolled

in a DOT consortium. Veriforce verifies

that selected contractors are enrolled,

and make these records available to OMS

personnel.

Internal Review

OMS regards the safety and health of

their contractors highly. To ensure that

Section 3

Version 1.1

27

contractors are up-to-date with training

and verification, OMS will perform a

review semi-annually for gaps in any

contractor compliance.

Recordkeeping

Throughout the process of construction

of DOT lines, all records of construction

data must be maintained. Some of these

include:

• Pipe and special invoices and

manufacturer information

• Fuse logs

• Pressure / Leak Testing information

• Weld tests and Welder certification

information

• Annual Review

• Records will be reviewed and audited

on an annual basis. This process will

correlate with the April 15th deadline

for DOT reporting.

4.0 Non-DOT Pipelines

4.1. Recordkeeping

Although non-regulated pipelines

do not require records be kept as

thoroughly and completely as regulated

pipelines, OMS expects that the same

recordkeeping procedures be followed.

5.0 Internal Compliance

It is OMS expectation that its operations

be reviewed on a regular basis by OMS

personnel who will assess its process

from a quality assurance and quality

control perspective. Some of these

functions are as follows.

5.1.Management of Change

When a change to an internal OMS

system occurs, a Management of Change

(MOC) process must be completed. This

is to ensure that all changes with OMS

production are documented thoroughly,

included with justification for the

change, cost savings (if applicable) and

desired outcome. These processes will

be reviewed from time to time to ensure

that changes being made are effective.

Changes that require an MOC process

include, but are not limited to:

• Administration Procedures

• Existing Lines

• Clean-ups

• Processes

• Type of Equipment Used

(Technology)

4.1 Material Transfer

4.1.1 General

Oasis Midstream Services (OMS) requires

that all operations be performed in a safe

and efficient manner. A major component

of operating this way involves the

process of handling and transporting

materials. This section reviews overviews

safe guidelines in order to handle and

transport materials for OMS in a safe and

professional manner.

A) Pipe Handling

1. Prior to loading or unloading any pipe,

trucks and trailers must be parked in

a way that they are level and secure.

Parking (hand) brakes should be set and

the wheels correctly chocked. The truck’s

engine should be off and left in gear and

the driver’s location known at all times.

Personnel directly involved should be

the only ones within the area of pipe

handling. Non-essential personnel must

stay clear of work area.

2. Poly pipe becomes extremely slippery

when wet. Caution should be used at all

times when handling poly pipe, especially

in rainy or snowy conditions. When

handling this pipe in these conditions

work slowly.

3. Black poly pipe becomes extremely

hot when exposed to direct sunlight,

therefore exercise caution and wear

appropriate PPE at all times when

handling black poly pipe.

B) Inventory

It is the responsibility of OMS personnel

to oversee and take record of all

equipment, pipes, and specials that

enter or leave the OMS yard. This will be

accomplished through internal inventory

management systems.

1.A) Equipment Storage - Jobsite

Storage areas should have smooth, level

surfaces that are free of stones, debris

and other materials that may damage

pipe.

If no adequate surface can be prepared,

pipe should be placed on evenly

spaced planking, racks, or other means

of supporting and protecting pipes

and equipment. Weather conditions

should also be considered when storing

materials that could be damaged by

extreme temperatures, ice, wind, or

moisture.

Pipe should be separated and stored

according to length and diameter as is

most feasible. Piles must only contain a

single size of pipe and be constructed in

a pyramid shape with the bottom layer

braced to prevent movement of any kind.

Rows of pipe should all for easy loading

and offloading of pipe by use of available

loading equipment.

1.B) Off-Site Storage

When storing pipe off-site, it should

be placed in pipe racks according to

length and diameter of pipe to prevent

from rolling or falling. Pipe larger than 2

inches should be stacked with spacing

strips.

If pipe is stored outdoors, pipe racks

should be made of material that will not

deteriorate.

1.C) Indoor/Outdoor Storage

Section 4

35

Version 1.1

Black poly pipe contains more than 2%

carbon black and will resist UV damage.

It may be stored unprotected from UV.

Other colors must be stored no longer

than two years.

C) Loading

1. Operator Experience

Only experienced operators are allowed

to use heavy equipment. This includes

a verification as per OSHA standard

1926.1427.

Staging area must be clear of workers,

equipment and other obstacles while

material is being loaded or unloaded and

must allow for clear line of sight.

2. Weight Limitations

Never exceed rated lifting capacity of

equipment.

The proper and safe use of forklifts

and other heavy equipment is the

responsibility of the contractor.

2.A) Inspection

• Check forks for jagged edges/burrs.

• Forks set to widest setting.

• Always lift from center.

2.B) Fork Application

Slide forks gently underneath pipe. Take

care to ensure that forks are not forced

underneath pipe, or positioned in a way

that could damage pipe racks.

2.C) Tilt Degree

When tilting the load of pipe or spools

tilt slightly back in order to stabilize and

prevent objects from rolling or sliding

forward without control.

2.D) Handling Loads

When transporting a load, move with the

load as close to the ground as possible,

taking care to not allow pipe to drag.

Drive as slowly as necessary as to avoid

bouncing.

3. Front End Loaders

The proper and safe use of front end

loaders falls under the responsibility of

the operator.

3.A) Compliance

If equipped with forks, loaders are used

as forklifts and treated as such. Always

maintain stability and center of gravity

precautions.

4. Pipe Handling Accessories

Accessories used to handle and support

pipe should be properly constructed and

rated above the capacity of the load that

they are intended to support.

Never exceed rated lifting capacity of equipment.

36


Chains, steel cable, wire rope, or hooks

are not to be used to handle poly pipe.

Slings must be wide band to distribute

load.

Nylon rope is acceptable to use with poly

pipe.

Only specially designed pipe tongs can

be used to lift poly pipe.

Lifting capacities of equipment and

attachments are not to be exceeded. The

angle between each lifting leg must not

exceed 45 degrees.

4.A) Unloading Coiled Pipe

Certain precautions must be taken into

consideration prior to unloading coiled

pipe. When unstrapping a load of coiled

pipe, it is necessary to ensure that

personnel are out of line with the ends

of pipe. Trailers must be level before

unloading either palletized or non-

palletized coils.

Never push, pull or roll coils off of trailer.

Never stand behind, under or around the

load as it is being unloaded.

When the securement banding is being

cut or removed, the coiled pipe has the

potential to whip away from the coil.

Ensure no personnel are in the area while

removing these bands.

DO NOT remove straps until sling is

secured.

4.B) Straight Length Pipe

It is necessary to ensure the load has not

shifted during transport before removing

securement straps.

Bundles should be unloaded with forks,

forked loaders or cranes with spreader

bars.

Steel bands used on bundles shall not

be removed until bundle is secure and

stabilized in storage area (remove from

ground with extension device).

Never stand on a load of pipe. If

breaking the banding is not possible

from the ground, personnel must remove

bands by the use of extension breaker

bars.

4.C) Strip Loads

Chains, steel cable, wire rope, or hooks are not to be used to handle

poly pipe. Slings must be wide band to distribute load. Nylon rope is

acceptable to use with poly pipe. Only specially designed pipe tongs

can be used to lift poly pipe.

Section 4

37

Version 1.1

Cranes should use spreader bars to

ensure proper transportation of the pipe.

Do not cut bands until pipe is secure in

storage.

Ensure all wheel chocks are in place

before beginning to unload.

D) Material Return

1. Material Transfer Forms (MTF)

All materials designated to arrive to,

or leave from Oasis yard, must have a

Material Transfer Form (MTF) completed

prior to being transported. Minimum

details to be included:

• Lease Name / Location

• AFE / LOE #

• Person receiving materials name/

company/signature

• Information about who the material

is for

2. Incoming Materials

2.A) Gate Check-in

All vendors or contractors delivering

material for OMS projects must check in

at the designated gate.

2.B) Bill of Lading

The yard personnel will unload the

material and check the material against

the packing list before signing the BOL

(Bill of Lading); personnel will then stage

the material in a predetermined location.

2.C) Damaged Material

If material is damaged beyond use/

repair, it will be cited as “Condition D”

and billed to contractor or rejected.

3. Outgoing Material

3.A) Gate Checkout

All personnel with the crews picking up

material must check in at the north gate.

Yard personnel will receive and must

have the following information before

loading any material:

1. Location

2. AFE

3. Name of Oasis supervisor

4. List of material required

The yard personnel will then fill out a

yard Material Transfer Form (MTF) and

have the person picking up the material

sign it before leaving.

All materials designated to arrive to, or leave from Oasis yard, must

have a Material Transfer Form (MTF) completed prior to being

transported.

Material Transfer Form]

4.2 ROW Corridor Establishment

4.2.1 General

The corridor is established as the

beginning stage of preparation for

installing a pipeline. Each department has

various roles to play in this development

process. They are outlined below, as well

as other establishment criteria.

A) Engineering – Develops Project Scope and Design

Responsibilities

1. The OMS engineering group will

develop all pressure scopes, elevation,

necessary equipment, operating

specifications, and other data relative

to the design and operation of the

proposed pipeline.

B) Land department – Manages Agreements and Planning

Responsibilities

1. Develop and approve proposed

pipeline route taking into consideration:

feasibility; financial viability; topography;

environmental; operational optimization;

and gaining the necessary approvals

from stakeholders. Record plat to county

and work with other reporting and

recording agencies.

2. Record plat to county and work with

other reporting and recording agencies.

3. Obtain and finalize ROW agreement

and landowner signoff.

4. After project completion, obtain final

signature from landowner to release the

project.

C) Construction Department – Completes the Project

Responsibilities

1. Manage contractors, understand

deadlines, follow regulatory guidelines,

maintain quality control and review OMS

programs in order to verify compliance.

In addition to ensuring all documentation

is maintained, remediation is

accomplished if necessary, and all

procedures are followed.

2. The construction department is also

required to notify Land Department

when a project is complete.

Yard personnel will receive and must have the following information

before loading any material:Location, AFE, Name of Oasis

supervisor, and the list of material required

Section 4

39

Version 1.1

4.3 Right of Way (ROW) Survey

4.3.1 General

The ROW is a route that is selected on a

preliminary basis to determine the scope

and cost of a project (determined by

the engineering department). The ROW

is a legal right, established by usage

or grant, to pass along a specific route

through grounds or property belonging

to another.

A) Construction Staking

Construction staking will be

performed with the direction of Oasis

Representatives. Oasis will mark route

of the centerline of the right-of-way or

ROW, as well as the ROW boundaries,

at the company’s discretion. Oasis

contractors will be responsible for

staking the ditch line within the right-

of-way ROW, which will be addressed

in the construction folder. Stakes will

be of such regularity that continuity

may be maintained, normally at 100-

to 200-foot intervals, along with the

beginning, middle and end of all points

of intersection, bores, and any/all other

landowner considerations. These stakes

will also be used to gauge construction

progress and to reference specific

locations on drawings and in reports.

Contractor is responsible for submitting

One Call to coordinate locating existing

pipelines, sewers, water or gas mains,

and electric or telephone installations.

Contractor shall take all necessary

precautions to protect and to avoid

damage or interference with these

facilities and shall repair these lines

immediately if damaged. Contractor is

responsible for maintaining all survey and

line markers. Failure to do so will result

in immediate shutdown of the job until

adequate markers are maintained.

B) As Build

-Reference Section 3-

C) Mapping

The scope of mapping is transferred

from survey to the Houston mapping

group with all required details and

info. Houston will then complete a field

map with all valves, roads, crossings,

landmarks, well names, etc.

4.4 ROW Construction

4.4.1 General

The Right of Way is the most permanent

picture of the quality of work that OMS

does. The process involved in acquiring,

maintaining, and leaving the ROW are

extremely important to our relationships

with our stakeholders, our assets, and

our reputation.

A) One Call

A One Call must be made prior to any

digging being performed. This can be

accomplished by calling 811 in both North

Dakota and Montana. In Montana, it is

also possible to fax-a-locate, however

there must be a pre-approval process

completed prior to the One Call being

processed. Montana’s One Call fax

number: (406) 752-7306 and website:

(www.mt1call.com).

*Faxing a locate to ND One Call will only

be available through the end of Dec

2014.

1. ‘Locate’ Wait Duration

40


After a One Call is made, line-locating

personnel will arrive at the desired

location within 48 hours of the One Call

submission and locate any Oasis, or other

entity’s lines. Oasis does not authorize

excavation prior to lines being located

under ANY circumstances, even if at

times a locate does not occur within 48

hours. The locate ticket must be followed

to the exact specifications written on the

ticket.

B) Line Locating

1. Project Relocating & Re-spots

After a line has been located, there are

many things that could require a “re-

spot” including:

Flags being moved by landowner;

Flags being moved by contractor/service

provider;

Uncertainty about accuracy of utility /

facility markers;

Change in job scope / area;

One Call tickets whose territory located

does not clearly indicate where the

locate starts or ends.

2. Distance from Flags

Minimum distance to maintain is 2 feet

from any flag or utility marker, in any

direction.

C) HydroVaccing

Hydrovaccing is the process of locating

a line with non-destructive means. Water

is used in lieu of shovels, excavation

equipment, etc. This process uses water

at high pressures to locate lines, and

has the additional benefit of vacuuming,

or removing the water/mud that is

created in the process. All tie-ins must be

hydrovacced, as well as any time a line

crossing is performed.

D) Relocating

Locate tickets are good for 21 days

only. The locate ticket will indicate the

expiration of the One Call ticket.

4.4.3 Preparation of Right of Way

(ROW)

A) Clearing

It is required prior to construction that

removal of brush, grass, weeds, trees,

Section 4

41

Version 1.1

crops, or anything that is on the ROW

occurs. Contractor will use Brush Hog, or

other sufficient means to accomplish this.

B) Grading

Preparing the ROW to the standard

grade, side hilling, acquiring proper highs

and lows to ensure your equipment gets

through without issue.

C) Topsoil

Cut into your soil top. Location

geography will determine depth of

topsoil. Topsoil is moved to one side of

ROW until the final step where it will be

redistributed evenly. State lands require

12 inches of topsoil to be removed.

4.4.4 ROW Access

Oasis Petroleum shall obtain easements

for ROW’s and permits for roads and

railroad crossings. Contractors may only

access the ROW from approved public

roads and points unless specifically

designated by Oasis representatives.

No two-track roads will be used unless

specifically authorized. Section lines

can only be used with prior Oasis

authorization.

Settlement of any off-ROW damages is

the sole responsibility of the contractor,

specific indemnity language is written

into Oasis Master Service Agreements.

4.4.5 Housekeeping

A) Poly shavings

Any waste materials created during the

process of stringing, fusing, bending,

or shaving pipe must be gathered and

disposed of in the correct manner. These

spare materials are not to be buried or

left behind.

B) Tools

Tools must be kept a minimum of 2

feet from the edge from any excavation

including open excavation, trench, bell

hole, etc.

C) Equipment Storage

Equipment storage locations/laydown

areas must be established prior to the

commencements of Oasis projects. All

agreements for additional space will

be initiated by the contractor but must

have Oasis approval prior to contact

with landowners. The cost of these

areas may be assessed only to the

contractor, however, Oasis may choose

to be involved or lead in the negotiation

process.

4.4.6 Preservation of ROW

Contractors shall offset all centerline and

locating stakes in a uniform manner, as

required for clearing and grading. After

clearing and grading contractors shall

reset the stakes in their original position.

Contractors will be held responsible for

the preservation of all stakes and line

markers. Contractors shall bear the cost

of replacing any stakes destroyed or lost

and re-survey work required.

4.5 Pipelining

4.5.1 General

The method used to lay, seal and bury

pipe is foundational to the success

of OMS. When contractors, internal

departments, and engineering groups

work together as a team, projects will be

42


completed correctly and to the quality

OMS aspires to. The following guidelines

have been created with the expectation

that contractors will have reference

material to rely on in order to uphold and

understand OMS requirements.

4.5.2 Stringing

A) Quality Control

OMS requests that pipe be strung along

the ROW and be aligned in accordance

with good pipeline construction practices

using pipe furnished only by Oasis.

Stringing of pipe on the ROW should

done in such a manner as to cause

minimal impact to the surround area, and

gaps shall be left at intervals to permit

use of the land and passage of farm

livestock and equipment across the ROW.

B) Unloading Methods

Pipe is to be unloaded from the stringing

trucks and lowered onto approved

padded skids by using canvas slings

or pipe hooks. Pipe is not to be rolled

off the truck. In areas where the ROW

crosses rocky terrain, special care shall

be taken in lowering the pipe to see that

pipe is not dropped on rocks or allowed

to rest on sharp or jagged surfaces.

Non-ferrous pipe can be pulled provided

that no visible damage occurs. A tag

line will be attached to hooks to control

the suspension of the pipe at each end

during stringing operations. In instances

where spooled pipe is being laid,

contractor is responsible for maintaining

pipe integrity. Pipe shall not be strung

without Oasis approval.

C) Inspection

After pipe has been strung, OMS

personnel and contractors will inspect it

thoroughly. Contractors will reimburse

Oasis for any and all damaged pipe.

D) Bedding

Bedding material must be clean sand or

soil and must not contain stones having

a maximum dimension larger than 2

inches. Material must be placed to a

minimum depth of

6 inches under the pipe and 6 inches

over the top of the pipe. The remaining

backfill must not contain rock larger than

6 inches. Organic material and wood are

not permitted for bedding and backfill

since they will deteriorate over time,

allowing for subsidence and subsequent

shifting and possible pipe damage.

4.5.3 Fusing

A) General Considerations

Butt-fusing operations and procedures

It is OMS expectation that contractors will provide trained and qualified personnel to perform butt-

fusion operations.

Section 4

43

Version 1.1

are not for novice employees. Personnel

must at minimum, prior to work,

understand and review manufacturer

recommendations and requirements.

Oasis can provide these materials if

contractor does not have access to

these materials. It is OMS expectation

that contractors will provide trained and

qualified personnel to perform butt-

fusion operations.

The process of butt fusion joins plain

end polyethylene pipes and fittings

end-to-end without couplings, inserts

or additional materials. Equipment must

be used to hold the components in

alignment and move the components

toward and away from each other

during preparation, heating and joining

operations. The equipment includes tools

to face (plane) and heat the component

ends.

Butt fusion equipment is manually

operated for smaller pipe sizes and

hydraulically operated for larger sizes.

The equipment covers a range of

pipe sizes and is properly set up by

adjusting pipe holding clamps, setting

the heating tool temperature, and for

hydraulic equipment, setting the fusion

joining pressure. Additional setup will be

required depending on the equipment.

Butt fusion equipment is set up,

operated and maintained in accordance

with the equipment manufacturer’s

instructions. Improperly set up, operated

or maintained fusion equipment can

produce faulty joints.

Other equipment such as pipe supports

and appropriate equipment for handling

pipe and fittings is required.

B) Butt Fusion Joining Restrictions

The ends of pipes and other components

such as fittings, flange adapters, MJ

adapters, etc., that are joined together

must have the same outside diameter

and comparable wall thickness.

Additional information about thickness

and diameter compatibility is found

below.

C) Outside Diameter (OD) Compatibility

Several OD controlled sizing systems

are used for Poly piping components.

These include IPS (iron pipe size), DIPS

(ductile iron pipe size), DIOD (ductile

iron outside diameter), CTS (copper

tubing size), inch-OD, or mm-OD as

applicable. For butt fusion joining, the

component ends being joined must be

the same outside diameter dimension

and system. For example, both pipes

must be the same IPS diameter, or the

same DIPS diameter. Different OD sizing

systems are not compatible, e.g., IPS and

DIPS cannot be butt fused to each other.

ID controlled (SIDR) pipes are joined

using insert type mechanical fittings and

are not suitable for butt fusion joining.

See Reference R-WL116 for applicable PE

pipe standards.

D) Wall Thickness (DR) Compatibility

The DR of the lower component ends

must not be less than 0.79 times the

DR of the higher component end. This

is to ensure the quality of flow rate, and

that pressures do not compromise the

components connections. In order to

determine if components with different

DR’s can be joined together, multiply the

higher DR by 0.79. If the lower DR is this

number or higher, the components can

be joined together using this procedure.

44


E) Fusion Quality Verification – Data Logging and Testing

It is recommended that hydraulic butt

fusion machines be equipped with data

logging technology to monitor and

record time, temperature and pressure

during fusion. Field fusion data logging

records that compare favorably with

tested trial fusion data logging records

can provide confidence in field fusion

quality. Data logging records must

be delivered to OMS personnel at the

completion of the project.

Fusion quality is tested by preparing a

trial fusion and performing destructive

tests such as two D638 tensile tests, a

DF2620 bent strap test, or ASTM F2634

tensile impact tests of specimens cut

from the fusion. Prior to testing, test

samples must be cooled to 73°F/23°C.

ASTM D638 tensile tests are conducted

on Type III or Type IV tensile bar

specimens machined from samples cut

longitudinally from each quadrant of a

trial fusion with the fusion in the center

of the reduced area. The sides of the

tensile bar specimen-reduced area must

be smooth and free from nicks and cuts.

If wall thickness is reduced, the tensile

specimen fused area should be from the

middle of the pipe wall. After machining,

condition test specimens by immersion

in temperature controlled circulating

air for not less than four hours or in

temperature controlled circulating water

for not less than one hour. Test at 73°F

and 2-in/min separation rate. Ductile

elongation should exceed 400% either

between the fusion and the end of the

gauge area, or for the entire gauge

area length. If desired, the tensile yield

strength of fusion test specimens and

pipe parent material test specimens may

be compared; however, the preferred

evaluation is ductile elongation rather

than tensile yield strength.

The pipes and specials shall be jointed

by automatic butt or electro fusion

welding to form a string above ground

and shall be supported by smooth

rollers. Three standard lengths of pipe on

each side of the fusion machine require

two roller supports per length of pipe.

All fusion joints shall be inspected and

assessed with joint record printouts from

the automatic butt or electro fusion

machine. Oasis personnel must approve

all joints before the contractor is allowed

to proceed with pipelining works. The

maximum pulling length of fusion jointed

PE pipes into position alongside or

directly into pipe trench after fusion

jointing shall not exceed 1,000 feet or

length limited by the hydraulic actuator

of the automatic butt fusion machine.

Dragging on ground surface is strictly

prohibited. All jointing of specials, tees

closing lengths etc., to be conducted in

the trench shall be by automatic electro

fusion couplers or other electro fusion

fittings.

Data logging records must be delivered to OMS personnel at the

completion of the project.

Section 4

45

Version 1.1

ASTM F2620 includes a bent strap test

for pipes having a wall thickness of 1 inch

(25 mm) or less. Butt fusions may be

evaluated by cutting straps from a trial

fusion and conducting an ASTM F2620

strap bend test. See Figure 2. The cut

through the fusion should be visually

examined. Voids or dis-bonded areas

are not acceptable. Strap specimens are

then bent with the pipe OD or ID to the

inside of the bend so that the ends of the

strap touch. Failure or dis-bonding at the

fusion is unacceptable.

F) Fusion Evaluation Tests – Mechanical Field and Laboratory Tests

ASTM standard tests and techniques

such as ASTM D638 tensile tests, ASTM

D1598 sustained pressure, ASTM D1599

quick burst, ASTM D1822 tensile impact

and ASTM F2634 high-speed tensile

impact are strongly recommended for

evaluating fusion joint quality. Published

ASTM testing procedures have been

confirmed to produce reliable, repeatable

results. Unproven, experimental, tests

and techniques even those that are being

developed, may be too stringent or

ineffective and are not reliable indicators

of fusion quality. Experimental tests

should not be used until published by

ASTM.

Tests such as root bend tests for metal

welds, bending a strap or coupon in

a bench vise, bending back and forth

multiple times, or hammering on bent

or unbent specimens are not reliable

indicators of butt fusion quality.

G) Weather Guidelines

Butt fusion can be successfully

performed over a broad range of field

conditions. However, some weather

and temperature conditions can affect

equipment operation or performance,

or could potentially introduce

contaminants, compromising joint

quality. Joining procedures may need

to be adjusted to compensate for wind,

weather or temperature. PE pipe and

fittings will expand and contract with

changes in temperature. If butt fusion

machine pipe clamp closure is limited,

shims of elastomeric material may be

necessary to secure very cold pipe

against slippage. In four-clamp machines,

shims should be used only in the outer

clamps.

1.A) Wind Effects

A windbreak or shelter should be used

when jobsite wind intensity exceeds

“gentle breeze” conditions.

Wind intensity above “strong breeze”

may require suspending fusing

operations.

4.5.4 Bending

A) Field-Bending – Steel Pipe

Joining procedures may need to be adjusted to compensate for wind,

weather or temperature.

46


Contractor shall make all necessary field

bends required in the construction of

the line except those shop bends which

company shall specifically furnish.

Contractor shall also fit the pipe to the

contour of the bottom of the ditch, and

shall restrict the arc and increase the

radius of the bends to such an extent as

will prevent the buckling or flattening

of the pipe, weakening of welds, and

will permit the free passage through

said bend of an internal inspection type

of pipeline scraper. All bends shall be

made using a lined bending shoe so as to

eliminate scratching and gouging of the

pipe.

Dimensions across the minimum and

maximum axis of the field bends will

be subject to measurement and shall

not have a difference in excess of 2.53

degrees.

Each field bend shall comply with the

following:

The bend must be smooth and uniform.

On pipe 12 inches and larger an internal

mandrel shall be used.

After bending the pipe must be free from

buckling, cracks, or any other mechanical

damage and must conform to the profile

of the completed ditch.

There must be no wrinkle bends or

mitered bends (not including deflections

up to 3 degrees that are caused by

misalignment).

No girth weld may be placed inside

the bending shoe if the weld protrudes

above the outer wall of the pipe.

Pipe containing a longitudinal weld must

be bent so that the seam is located near

the neutral axis.

No bend shall be made any closer than 5

feet from the end of a joint or 3 feet from

an existing girth weld.

B) Field Bend Data - Steel Pipe

All field bends shall be made by the cold

stretch bending method, and an accurate

method of measurement shall be used to

determine the tolerances as follows:

4.5.5 Trenching / Excavation

A) Trenching / Excavation Permitting

1) Dig Permit

Prior to any excavation an Oasis dig

permit must be complete [OMS Form

1000]. Included in this permit are

required action items including: ensuring

the applicable state One Call system

has been utilized; all potential utilities

and facilities have been identified; and

areas of concern hydrovacced etc. If an

excavation is determined to be 48 inches

or greater in depth, adequate sloping,

shoring, or trench boxes must be created

or installed. Other action items include:

North Dakota One Call has been notified

and contacts conducted to determine

existence and location of underground

facilities in the work area.

Available records have been referenced

and a plot plan indicating the location

of all underground facilities has been

provided and is available for reference at

the job site.

Have Oasis operations personnel been

consulted for obtaining or discussing:

Section 4

47

Version 1.1

Plot plans

Pipeline or facility maps

Lease maps

Has the work area been checked for

facilities/pipelines, or utility markers?

And companies on markers contacted?

Are there ANY signs of ground

disturbance within the proposed work

area?

Have attempts been made to

communicate with landowner to verify

buried utilities?

All necessary approvals, notification and

agreements have been obtained.

A pre-job safety meeting including

JSA and emergency response plan

completed?

The proposed ground disturbance

area(s) are identified and all underground

facilities in the dig zone/search zone

have been identified and incorporated

into the plan.

Approved techniques for exposing

facilities with 2 feet of ground

disturbance have been (or will be)

used to verify the location of all known

underground facilities.

Other required Safe Work Permits have

been issued (Confined Space, Hot Work,

LOTO, etc.)

Precautions have been taken to prevent

contact with overhead power lines

New non-metallic underground facilities

are being installed with tracers

All personnel involved in the excavation

have received the appropriate training

Risk has been assessed and provisions

have been made to address unattended

open excavations to ensure the safety

of other contractors, the public, wildlife,

etc.

B) Daily Inspection

A competent person must inspect

trenches that individuals plan to enter, or

could potentially enter as a part of their

All trench boxes or shoring must be approved by the manufacturer to be used at the depth they are

planned to be used in, for the type of material they are supporting, and must not be modified in any manner

that could affect the integrity or safety of these units.

48


work scope. Trenches will be tested for:

resistivity of the soil; porosity of the soil

(classification test); crumbling; distance

of spoil pile from trench; as well as any

shoring/trench box systems. All trench

boxes or shoring must be approved by

the manufacturer to be used at the depth

they are planned to be used in, for the

type of material they are supporting, and

must not be modified in any manner that

could affect the integrity or safety of

these units.

C) Trench Boxes / Shoring

Trench boxes and shoring are protective

measures designed to eliminate the

likelihood of a trench caving in while

personnel are working inside the trench.

These methods are required whenever

a trench or open excavation requires

an employee to work below 4 feet of

depth, and proper sloping cannot be

established. Trench boxes must extend a

minimum of 18 inches above the edge of

the trench, on both sides of the trench.

4.5.6 Lowering Pipe

A) Trench Bed Condition

The trench bottom shall be free from all

rocks, boulders, stones or hard particles

when particles, which may damage

the pipe walls. The trench bed should

maintain the minimum approved depth

taking into consideration the contour of

the land.

Before any pipes or specials are lowered

into the trench, they are to be inspected

again for deep cuts and scratches

described above. The fusion joints should

also have cooled sufficiently (specified

cooling time for the last joint has

elapsed) before stress is imposed on any

premade joints.

When lowering pipe into trenches, care

should be taken to avoid scoring of

the pipe by contact with the sides and

bottom of the trench. Special care is

needed when passing under/around

obstructions or other utilities.

Pipe roller supports for the first four

lengths of pipes from the pipe end to

be lowered into the trench shall be

provided. Cut section of rejected or

damaged PE pipes, planks and rope shall

be used for protecting the remaining

pipes where appropriate, but wire ropes

or chains shall not be used.

B) Trench Bed Material

Trench bottoms shall be layered with

well-graded earth that is free from

stones or hard particles larger that may

damage pipe. Under no circumstances

shall hot bending, in any form, be

allowed on site. A distance of one foot

from obstructions and other services

must be maintained for the length of

the pipeline. The pipe shall be kept as

central as possible within the trench

to enable correct side-fill compaction.

Some snaking to compensate for thermal

expansion of the pipe is acceptable.

Pipes and fittings to be embedded in

concrete shall be firmly held in position

and protected from damage during

pouring or compaction by a heavy-duty

polyethylene sheet. Should any pipe

or specials become either partially or

wholly clogged before final acceptance

of work, it shall be cleaned out or

replaced by the contractor at his own

expense.

After laying the interior of pipes or

specials shall be carefully cleaned to

Section 4

49

Version 1.1

remove any debris, dirt, stones or other

matter that may have entered during

installation.

Except when work is proceeding, all

open ends of pipes and specials in the

trench shall be kept closed by means of

a fine wire gauge, wooden stopper or

other approved means to prevent the

entry of dirt, soil, stones and the like, but

still allow the entry of water.

C) Inspection & Testing

Inspectors must look for deep cuts or

scratches that gouge deeper than 10%

of the pipe wall thickness. The depth

of these gouges should be measured

with approved depth gauges of suitable

accuracy supplied or approved by

OMS personnel. All damaged or flawed

sections of pipe will be cut out and

removed to the satisfaction of the Oasis

representative before jointing according

to OMS Section 4.13.

4.4.7 Welding

A) General

1.A) Contractors are responsible for

adhering to welding specifications and

guidelines set out by ASME B31.8.

1.B) Hot Work Permits must be

completed by contractors when any hot

work is performed on behalf of OMS.

B) Requirements

Joint design, materials, procedures

and practices shall be in accordance

with the latest edition of API standard

1104, “Standard for welding pipelines

and related facilities,” ASME code B3

1.8, “Gas Transmission and Distribution

Piping Systems” and all applicable DOT

regulations.

C) Method

Shielded metal-arc welding shall be used

for all manual welding. Gas metal-arc

and submerged metal-arc welding may

be used with prior approval from Oasis.

Back-up rings are prohibited.

D) Line Pipe Weld Procedures

1. Requirements

With manual, shielded metal-arc butt

welds, pipe with a wall thickness ¼ inch

and less shall have three weld beads.

Four or more beads shall be used on

pipe having a thickness greater than ¼

inch. Two welders will be used to run the

stringer bead on pipe 12 inches O.D. and

larger.

The second bead, or hot pass, shall be

applied immediately after the stringer

bead. Hot passes shall be completed

up to and including the last completed

stringer bead whenever the stringer

welding is stopped for any reason and

at the end of the day’s work. No two

succeeding passes shall start or stop at

the same point. All beads are to be made

by starting the pass near the top of the

pipe and proceeding downward on each

side of the pipe to the bottom. On any

land-laid section of line not more than

an interval of 25 joints shall separate the

hot pass welding and the filler and cap

welding processes. This interval may be

reduced by Oasis inspector if conditions

warrant. Before the end of the day, all

cap welding shall be complete.

2. Qualifications

Prior to the start of production a

detailed procedure shall be established

50


and verified to demonstrate that welds

having suitable mechanical properties

and soundness can be accomplished by

this procedure. The quality of the welds

shall be determined by testing with the

destructive tests described below.

3. Records

The details of each qualified procedure

shall be recorded and maintained on

approved forms. This record shall show

complete results of the procedure

qualification tests. Similar records shall

be made for all weld methods employed

whether in field or shop construction.

Strict compliance with these procedures

shall be required during construction

except where a change is specifically

authorized by Oasis and its qualification

recorded.

4. Procedure Specifications


specific welding procedures and welder

qualifications as outlined in ASME B

31.8., however, Oasis may at times accept

other standards that are equal to or more

stringent than ASME B 31.8.

5. Line Pipe Welder Qualification

Welders must pass all required

verification tests in order to weld any

OMS DOT, or other line.

6. Qualification Test

Contractor shall provide only competent,

skilled and qualified welders. Each

welder shall be required to pass

satisfactorily a test in accordance with

ASME B 31.8 for each of the procedures

to which he will be assigned, before

being allowed to weld on the line.

Oasis’ welding inspectors or designated

qualified representatives, other than an

employee of the contractor, shall witness

the tests and judge the specimens.

A report form describing each of the

procedures and the results of each test

shall be completed for each welder

and submitted to the Oasis. A welder is

disqualified at any time during the test if

his performance is judged unsatisfactory

by an Oasis inspector.

7. Equipment

Contractor shall furnish all welding

equipment, prepare all spools used

in testing and shall bear all cost in

connection with the test other than the

cost of the pipe, which will be furnished

by OMS. Test welds will be accomplished

and the weld quality tested in

accordance with ASME B 31.8, unless

otherwise specified. An Oasis approved

pulling machine for tensile tests will be

furnished by contractor with certified

gauge and calibration dates and tests.

8. Preparation For Welding Line Pipe

8.A) Welding Surfaces

Welding surfaces must be thoroughly

cleaned so as to be dry and free from

paint, oil, rust, scale, and any other

material detrimental to weld quality.

Each bead shall be ground or buffed

before any following weld passes are

made.

8.B) Alignment

8.B.1) Joints

The ends of pipe to pipe or fitting to

pipe joints shall be aligned as accurately

as practicable in consideration of

Section 4

51

Version 1.1

the commercial tolerances on pipe

diameters, wall thickness and out-of-

roundness. Methods of alignment to

provide the proper size and deposition of

stringer beads shall comply API standard

1104, except as noted below:

Internal line-up clamps shall be used for

all welded joints on pipe sizes 12-inch

and larger, or where specified by Oasis,

except on tie-in and other prohibitive

joints. Internal line-up clamps shall be

left in place until the stringer bead has

been 1003 completed, unless otherwise

approved by company welding inspector.

External line-up clamps shall be left in

place until a minimum of 503 of the

stringer bead, which shall be equally

spaced, has been completed.

Spacing tools shall be used in

conjunction with the line-up clamp to

assure proper joint spacing and to permit

full weld penetration.

When external clamps are used, all

tack welds shall be ground to ensure

complete stringer bead continuity.

All slag cavities, surface porosity, cold

laps, starts and stops, and high points

shall be removed by grinding.

All slag and remaining flux shall be

buffed with a power buffer between

passes.

8.B.2) Rotation Of Seams

Electric resistance welded pipe shall be

aligned so that the longitudinal seams

will be located on either side of the

line within 30 degrees of horizontal.

Successive joints of pipe shall be rotated

to the right or left not less than 20

degrees, or have the seam located on the

opposite side to avoid aligning seams on

adjacent joints. Longitudinal seams on

pipe bends, however, shall be located 90

degrees from the radius of the bend. On

bends requiring more than one joint of

pipe, longitudinal seams shall be located

180 degrees from each other.

8.C) Weather

Welding areas must be protected from

conditions that would impair the quality

of the completed weld. At times this

may require constructing a barrier wall

or enclosure (provided with adequate

ventilation) to protect the welds from

adverse weather conditions.

8.D) Materials And Equipment For Welding

8.D.1) Electrodes - Rod or Wire

Electrodes shall be in size and kind

suitable for the material being welded

and acceptable to Oasis. They shall

conform to API standard 1104.

8.D.2) Shielding Gases

Shall conform to API standard 1104.

8.D.3) Handling & Storage

Welding electrodes must be protected

from all forms of deterioration prior

to actual use. Bectrodes and fluxes,

which show any sign of damage or

deterioration, shall not be used. Any

welding materials condemned by Oasis

welding inspector shall be promptly

removed from the job site and disposed

of according to contractors waste

management procedures.

52


8.E) Equipment

8.E.1) Machines

Welding machines shall be operated at

the approximate voltage and current

ranges recommended for each type of

electrode used and shall not be operated

beyond their rated capacity. Generating

sets and/or automatic or semiautomatic

welding machines shall be maintained in

good working order and equipment that

does not meet OMS requirements must

be either repaired or replaced.

8.E.2) Leads

The ground leads of welding machines

shall be fastened securely to the pipe

metal by means of clamps or other

mechanical means (not by welding). No

arcing between the ground leads and the

pipe will be permitted and any leads with

insulation damaged to the extent that

wire is exposed shall be discarded.

8.F) Inspection & Testing of Line Pipe Welds

8.F.1) Non-Destructive Testing

All completed weld surfaces and

surrounding areas shall be cleaned and

excessive spatter must be removed prior

to welding inspection.

Radiographic Inspection

All field welds must have a radiographic

inspection completed for 10% of the

weld. A larger percentage up to and

including 10% of the field welds may be

inspected at OMS discretion. A minimum

of 10% of all field welds made within

railroad or public highway ROW, river

and stream crossing rights-of-way,

above ground piping, and at tie-ins will

be inspected for 10% of the weld. The

contractor may be required to provide

transportation to the job site and along

the ROW as well as to provide space at

the work location for equipment and

personnel.

Leads

Magnetic particle, ultrasonic, or other

non-destructive test methods may be

utilized at OMS discretion.

Defects

All welds or portions of welds disclosed

by radiographic inspection to be

defective will be repaired in accordance

with API 1104 at contractor’s expense.

Welds which are found to be defective

by OMS inspectors will be cut out and

tested in the method described in

section 8.H of this manual.

8.G) Visual Inspection

Completed welds must be visually

inspected and marked as acceptable

by OMS inspectors before the joint

coating is applied. It will not be deemed

satisfactory unless it meets the standards

of acceptability and testing requirements

as defined in API standard 1104 for

welding of pipelines.

8.H) Destructive Tests of Field Welds

Contractors will be responsible to cut

out any welds as required by Oasis

and deliver the sample for testing and

examination, and re-weld the pipe. OMS

will not require the contractor to cut out

more than one non defective weld per

welder without reimbursing contractor,

Section 4

53

Version 1.1

regardless of whether the weld was

cut out because of the results of non-

destructive testing methods (other

than radiographic), visual inspection or

other reasons. Coupons cut from test

welds shall be pulled for tensile strength

by an OMS approved pulling machine,

furnished by contractor. Welds may

be further tested by cutting additional

coupons for bend tests and nick-

break tests and the ductility and grain

structure of the welded metal examined.

Contractors will replace all defective

welds and one non-defective weld per

welder at their expense. A record of the

results of each test shall be jointly signed

by an Oasis representative and the

contractor.

8.I) Weld Identification

Oasis shall assign a specific number

to each contractor welder. It shall be

the duty of each welder to personally

affix such number with a permanent

waterproof felt or paint marker, adjacent

to each weld on which he works for

future identification. In the event any

welder leaves the project, his number

will be voided and not duplicated

when another welder is utilized. If

radiographic or physical tests indicate

the production of defective welds, the

welder responsible shall be disqualified

from further welding on the project.

Should two or more welders participate

in making the defective welds, the

contractor, welding foreman and OMS

inspector shall determine which welder

was responsible for the defective work.

8.J) Replacement of Test Welds or Rejected Welds

When welding the line together at places

where welds have been removed, if

possible, one weld shall be made after

moving the line back into position;

otherwise two welds shall be made by

installing a spool with the minimum

length of 1¼ times the pipe diameter.

8.K) Repair of Weld Defects

Weld defects, other than cracks, may be

repaired if the weld was not previously

repaired if authorized by an OMS

inspector. Such defects shall be removed

by grinding to clean, sound metal before

re-welding and shown by radiographic

inspection to be free of defects before

acceptance. Should laminations, split

end or longitudinal seam defects be

discovered in the pipe, the full joint

containing the defect shall be removed

from the line.

8.L) Standard of Acceptability

Minimum acceptable standards for

penetration, fusion, burned-through

areas, slag inclusion, gas pockets,

discontinuities and undercutting shall be

in accordance with API standard 1104,

and ASME 831.8 code.

8.M) Arc Burns

Contractor shall prevent arc burns. Arc

burns, where they occur, shall be cut out

at contractor’s expense.

8.N) Preheating & Stress Relieving

8.M.1) General Practices

8.O) Preheating

When the weld procedures and/or

carbon content or the carbon equivalent

of the pipe requires preheating, or the

ambient temperature is 40°F or less,

the weld zone shall be preheated to an

appropriate uniform temperature. The

hot pass shall be made no longer than

five minutes after the stringer bead and

before the weld joint is cooled to below

200°F. The preheating temperature shall

be accurately tested to assure that the

required temperature is obtained prior

to and maintained during the welding

operation. OMS will pay for preheating

required during cold weather. Preheating

required by weld procedures will not be

paid by Oasis.

8.P) Stress Relief

Stress relieving may be designated

by Oasis and shall be accomplished

in accordance with the instructions

in ASME b 31.8 and the Oasis welding

inspector. Butt welds on weld-end valves

shall not be stress relieved and in no

case shall cold expanded pipe be stress

relieved. Oasis will pay for stress relief.

4.9 Facility Construction

4.9.1 General

Facility construction covers many

important aspects of OMS operations.

The quality of the equipment provided,

as well as ensuring the proper application

and planning is imperative to the safe

and efficient operation of OMS pipelines.

A) Pumps

1. Installation

Depending on the elevation and

number of wells on site, pumps are

sized accordingly by OMS engineering

personnel.

Hand sketched drawing are sent from the

field to welding shops.

CAD drawings are then produced with a

Make to Order (MTO) for project scope.

Parts are ordered and documented as

a part of the project file. Fabricated

packages are to be delivered to the

field and recorded using OMS required

Material Transfer Forms. Electronic

versions must be given to OMS personnel

as well as hard copies maintained in the

field. Fabrication shops must maintain

X-ray maps, Material Transfer Forms and

welder information.

Pumps will ordinarily be constructed

prior to being delivered to the field. All

drawings and plans are required to be

preapproved by OMS engineers.

B) Houses

In most applications, houses will be

designed and built prior to being

installed on locations.

1. Installation

Houses are to be set, leveled and sealed

at the time of pump set. Considerations

must be taken to identify prevailing wind

direction in order to protect doors from

being damaged.

2. Insulation

Freshwater connections are to be heated

and insulated to prevent freezing.

3. Heat Tape

Any pipe that is exposed to the elements

above ground require heat tape and

insulation to prevent freezing.

C) Risers

Risers are to be constructed by certified

API 1104 welders. They will have both a

purge as well as a non-purge procedure.

We will use 316 stainless steel for all

saltwater above ground pipe. The

riser should be coated with a VisoTaq

Coating.

D) Instrumentation and Electrical (I&E)

1. Automation

Transfer pumps are controlled by

two controls, one is located within

production tanks and monitors high

and low levels, the other is the pressure

transducer controlling the pump per its

engineered MAOP.

2. Measurement

Measurement meters must be calibrated

frequently to ensure accuracy.

How frequently this occurs is to be

designated by OMS Engineering. All

66


calibrations must be accompanied with

documentation.

Leak tests should be performed

quarterly.

4.10 Coating

4.10.1 General

Protective coatings are imperative for the

integrity of all pipelines. Dings, scrapes

or nicks can cause anomalies that last the

lifetime of the line, and pose serious risk

to all stakeholders near pipelines as well

as significant risk to the environment.

A) Painting

1. Surface Preparation

Surface shall be degreased prior to

sandblasting. Organic solvents, alkaline

solutions, steam, hot water with

detergents, or other systems that will

completely remove dirt, oil, grease, etc.,

may be used.

1.A) Edge Preparation

All edges shall be ground to a minimum

of a 1/8 inch radius. This includes clips,

baffles, nozzle connections, etc.

1.B) Surface Abrasion

The immersion service surface shall

be blasted to a NACE (National

Association of Corrosion Engineers)

No. 1 or SSPC (Society for Protective

Coatings)-sp5-63 white metal blast

cleaned surface. An anchor pattern or

“tooth” in the metal shall be established

according to the coating manufacturer’s

recommendations. The anchor pattern

shall be sharp and no evidence of a

polished surface is allowed.

1.C) Sandblasting

The external surface to be painted shall

be blasted to a NACE no. 3 or SSPC sp-

6-63 commercial blast cleaned surface.

The surface profile should be 1.5 to 2.0

mils.

Blasting shall be done with washed

sharp silica sand of 16/35-grade mesh

or finer. This sand shall be clean, dry

and free of clay particles and other

extraneous matter or, the grit used shall

be sharp silica sand, steel slag grit similar

or equal to black beauty bb 16 or any

other abrasive that has a sharp hard

cutting surface, properly graded, non-

contaminating, dry and best quality.

Steel surfaces shall not be blasted when

the surface temperature is less than 5°F

above the dew point, relative humidity is

greater that 80%, or there is a possibility

that the blasted surface will be subject

to wetting before the first coat of primer

can be applied. No painting shall take

place when the ambient temperature is

below 50°F.

1.D) Surface Cleaning after Sandblasting

Traces of blasting abrasive and dust

must be removed with a vacuum

or by brushing. Care must be taken

to avoid contaminating the surface

with fingerprints or from foreign and

potentially detrimental material from the

workers clothes or shoes.

1.E) Immediate Priming

Freshly blasted surfaces are subject to

immediate corrosion, particularly in areas

of high humidity. After surfaces are blast

cleaned then they can be prime-coated

before visible or detrimental re-rusting

Section 4

67

Version 1.1

occurs. Blasted surfaces shall be prime-

coated or plastic-coated no later than at

the end of the same workday.

A 12-inch wide strip of uncoated, blasted

surface shall be left between primed

surfaces and those non-blasted surfaces

to prevent damage to the newly dried

coating when additional blasting is

done. When blast cleaning is resumed,

the 12-inch strip of previously blasted

surface shall require only a light brush

blast to remove any rust that might

remain. Cleaning shall be accomplished

by holding the cleaning nozzle in a

direction away from the coated surface

and personnel.

1.D) Compressed Air Quality

The compressed air used for blasting

shall be free of detrimental amounts of

water and oil. Adequate traps, filters

and separators shall be provided at the

compressor and must be checked daily.

1.E) Metallic Surfaces

All non-metallic surfaces shall be clean,

dry and free from scale, oil and dirt.

Contractors shall protect all gasket

surfaces, valve stems, name plates,

pressure gauges, instrument cases,

gauge glasses and all previously

installed and coated equipment

including galvanizing. If the coating on

any previously installed equipment is

damaged, the damage will be repaired

at the contractor’s expense. If any

previously installed equipment is

damaged during coating, the equipment

will be replaced or repaired by the

contractor. All tape protection shall be

removed after coating.

B) External Painting

All piping, equipment, structures

and metal portions of buildings, not

galvanized or of aluminum construction,

shall be painted to protect against

corrosion and to provide a satisfactory

appearance. Equipment and piping to

be insulated will be protected with one

primer coat only. A minimum of one

primer coat and one finish coat shall

be applied to un-insulated equipment.

Floors may be colored, coated or hard-

surfaced as specified.

Paint shall be spray applied in

accordance with the manufacturer’s

recommendations. Any or additions by

the company will take precedent over

the manufacturer’s recommendations.

Only competent personnel applying

coating by proper techniques are

authorized to perform this task. After

coatings have been applied facilities shall

not contain sags, runs, wrinkles, spots,

blisters or other application flaws which

would cause premature coating failure.

The finished external coating shall be

free of holidays when checked with a

67.5 volt Holiday Detector.

1. Coating Equipment Inspection

All spray equipment shall be inspected

and approved by OMS personnel before

any application is begun.

2. Moisture Trap

Moisture traps are to be used by placing

them in line from air supply to pressure

pot and spray gun. This trap shall be

opened slightly to provide a continuous

bleed.

68


3. Use of Regulators/Gauges

Regulators and gauges shall be provided

for air to both pressure pot and spray

gun.

4. Application Distance-Primer

Primer shall not be applied closer than

12-inches to a non-blasted area. Any

subsequent blasting operation shall not

result in sand particles being embedded

in the paint film.

5. Spray Guns

Spray guns are to be held perpendicular

to the surface being painted, and

handled and adjusted in such a manner

that dry overspray is kept to a minimum.

6. Sequence

The sequence to be followed in painting

shall be such that a minimum of damage

to finish coatings will result.

7. Confined Space Ventilation

When paint is being applied to the

interior of tanks or confined areas,

sufficient blowers and fans shall be

installed to provide adequate ventilation.

8. Priming

The prime coat shall be a high build type

with a minimum dry film thickness of five

(5.0) mils to six (6.0) mils, depending on

the brand used.

9. Brand Use

All materials required for external

painting and finishing shall be of the

brand(s) manufactured by: Polyguard or

a similar vendor provided the quality is

not reduced.

Ground level protection should be

ViscoTaq Coat Wrap ST or equivalent.

Changes in brand/type may be

approved, but only by OMS written

authorization.

Coating materials shall be stored in a

cool dry place free from the potential

of spark or flame. Paint materials

susceptible to freezing are not to be

stored where the temperature will drop

below 32°F. All such materials shall be

used or applied in strict accordance with

manufacturer’s directions.

10. External Applications

Application of the external coatings is

allowed only when the air, surface and

product temperatures are above 50°F

and at least 5°F above the dew point.

One finish coat of not less than two (2.0)

to two point five (2.5) dry mils must be

applied.

11. Additional Coats

Surfaces are not to be recoated until the

preceding coat has properly dried or

cured. The surface may be considered

ready for recoating when the next coat

can be applied without the development

of paint film irregularities, such as lifting

or loss of adhesion of the undercoat.

However, the minimum or maximum

drying or curing time specified by

the paint manufacturer shall be the

acceptable recoat period. Paint shall not

be force dried under conditions that will

cause wrinkling, blistering, formation of

pores, or which will be detrimental to its

condition or appearance.

Section 4

69

Version 1.1

12. Paint Thinning

Only best quality products will be used

and paints shall be thinned only as

recommended by the manufacturer.

Resin systems or two component

systems will be used within the pot-life

time specified and in no case shall any

thinning be used.

13. Curing

Each coat will be thoroughly dried or

cured before the next coat is applied.

14. Paint Damage

Where paint has been damaged in

handling, all damaged and loosely

adhering paint shall be removed and the

surface thoroughly cleaned. Edges of the

breaks shall be feathered and designated

prime and finish coats applied.

C) Jeep Sticks

If a nick (or holiday) is found in a coated

steel pipe, a hot melt patch is needed

to repair it. Recommended use of 3M

Scotchkote Hot Melt Patch Compound

226P.

Holiday detection equipment must be

used to detect holidays in the coating of

the pipe.

F) Pipe Wrap / Tape

For rocky soil a protective coating wrap

such as Tuff-N-Nuff Rockshield should

be used to keep large jagged edges from

affecting the coating of the pipe. (See

Appendices)

G) Insulation

Pipe should be adequately insulated if

placed above 4 feet in depth. The quality

of the insulation such be such that the

R-Factor can protect against anticipated

temperatures.

4.11 Tracer Tape & Wire

4.11.1 General

It is imperative that all utilities installed

by Oasis Midstream Services have the

ability to be located. This includes

correct installation, and integrity

management of locating devices.

A) Depth

All tape must be installed above the

pipe and a minimum of 2 feet below the

surface of the top of the existing ground

surface and be made of magnetic

material. When soil is crowned, tracer

tape may need to be installed at an even

greater depth. Consult OMS personnel if

adequate depth is in question.

B) Wire Location

All tracer wire must be installed

according to section DOT 192.321 or 195.

Test leads should be installed ideally

every ¼ mile to ensure adequate

coverage.

Test leads shall be color coded with

a proper sticker to indicate company

name, product in pipe and emergency

contact, preferably a tri-sided

(triangular) post.

70


C) Wire Protection

Wires must be protected from corrosion

as well as from abnormal protrusions

underground. For this reason anode

protection is required. Tracer wire

should be constructed to the following

specifications:

Composed of a dead soft annealed

copper conductor utilizing UNS C10200

grade copper;

Insulated in 45 MIL High Density,

High Molecular Weight Polyethylene

(HMWPE);

Shall be UL listed, rated for direct burial,

moisture, gasoline and oil resistant, and

suitable for operations at 600 volts.

4.12 Backfill

4.12.1 Material

The quality and type of material used

for backfilling after construction is

imperative to the life of the pipeline.

Using material of poor quality, can either

damage the pipe or require contractors

to return to the ROW to re-compact

soil. Backfill 12 inches above top of pipe

shall be free from rocks, frozen clods

or other hard objects. Contractors

are required to bear the cost of any

special treatment necessary to eliminate

such hard objects. Where required by

company or by ROW agreement, topsoil

shall be segregated from other spoil

and placed at the top of the fill to the

specified depth. In cultivated areas, no

rock shall be placed in the top of the fill

above the depth of normal tilling. Excess

rock must be disposed of by contractor

to the satisfaction of OMS personnel.

Contractors must also comply with

requirements concerning the order, in

which respective materials are backfilled,

contained in ROW restrictions.

4.12.2 Backfill Method

A) Backfill Material

Immediately after the pipe has been

lowered, it shall be shaded by filling the

ditch over the pipe with backfill material.

Backfill material shall be placed around

the pipeline in a manner to ensure

that no significant rocks, vegetation

or foreign objects strike or contact

the pipeline in a way that could cause

damage. Special considerations for the

initial 2 feet of backfill [ref. sec. 4.12.1]

B) General

Backfilling methodology should be done

in a way to maintain the integrity of the

ROW as well as a minimum disturbance

area. Backfilling shall be done in such a

manner as to ensure all area below and

around the pipe is surrounded by fill dirt.

Contractors are to use any acceptable

method approved by OMS personnel

in order to ensure compaction of the

backfill while not applying so much

pressure that the pipe may lose its

shape. Backfill packing shall not be done

through rocky land where the exterior

pipe or coating might be damaged,

or through sections where drain tile is

encountered and might be damaged.

All pipe must be buried a minimum of 6’

Deep, unless otherwise required by OMS

personnel or governing authorities

C) Padding

Where padding of the pipe is required

materials must be deposited in ditch

simultaneously on both sides of the pipe.

Section 4

71

Version 1.1

In the event the native ditch material

is considered by the company to be

unsuitable for backfill material, the

contractor shall purchase, haul, place

and choose the highest quality backfill

material possible in accordance with

these instructions. Contractors may use

a padding machine to achieve padding

requirements without hauling select back

fill to the worksite. If a shaker bucket is

used in place of a padding machine or

hauling in pad material, padding costs

are considered to be a part of the bid

price of the project.

D) Padding Density

Padding shall extend across the full

width of the ditch and be thoroughly

compacted until a minimum of 12 inches

of padding is in place. If more than one

pipeline is in the ditch, the select backfill

material shall be placed between the

lines and shall be brought to a level of

12 inches above the highest line. OMS

reserves the option to require additional

padding in extremely rocky areas.

The remaining backfill shall be placed in

the pipeline ditch and spread on both

sides of the pipeline ditch. ROW that

has been disturbed during construction

shall be graded and tilled in a manner

satisfactory to OMS and the landowner

and seeded. Backfilling across drainage

ditches, irrigation ditches, terraces, levee

districts, railroads, public highways,

private drives, trails, roads, or streams

shall be compacted to at least 953

standard proctor density throughout in

a manner satisfactory to company and

to any private or governmental authority

having jurisdiction.

4.12.3 Final Compaction

Compaction may be accomplished by

tamping or other method approved

by OMS. “Walking in” with a track or

wheeled vehicle is normally acceptable

on wide ditches, subject to prior OMS

approval. There shall be a minimum of

30 inches of cover material over the pipe

prior to compaction by vehicles. Wheels

and tracks must be narrower than the

ditch line for effective compaction.

Where non-ferrous or large diameter

thin wall pipe is involved, a limit may

be placed by OMS on the maximum

weight of the vehicle, or there may be a

requirement that the line be pressurized

during the operation. Compaction to a

density that will prevent excess settling

of the ditch backfill material is required.

A) Moisture

At road crossings where selected

backfill material is required, it shall

have the proper moisture content to

reach necessary 80% compaction and

the moisture content shall be uniform

throughout each layer.

4.12.4 Restoration of Construction Areas

Roads, slopes, creek banks, levees and

other places where earth has been

moved to facilitate the operation of

contractor equipment, the contractor

is required to restore these areas to

their original profile and condition,

to the satisfaction of OMS and/or the

landowner.

4.12.5 Overburden / Crown

Backfill over the pipe ditch shall be

crowned to a height of not less than 8

inches (8”) and no more than 12 inches

72


(12”) above the adjacent ground surface,

except through irrigated farm land

where the backfill will be compacted

to the satisfaction of company and the

landowner. Through rocky lands where

livestock is confined, 20-foot wide gaps

shall be provided across the backfilled

line at 100-yard intervals to provide

passageway for livestock.

Gaps shall be level with surrounding

ground and surfaced with backfill

material free from large and sharp rocks,

all to the satisfaction of OMS personnel

and/or the landowner.

4.12.6 Irrigation & Drainage

When backfilling across irrigated fields

contractors must provide furrows across

pipeline ROW as required by OMS

personnel and/or landowner, in order

to direct the flow of water into normal

irrigation courses.Finished backfills must

be sufficiently level to permit normal

irrigation, even if harrowing, disking or

hand raking is required. When borrowed

dirt is necessary to crown the backfill

to the required height, Oasis and those

having jurisdiction of the property must

approve the manner and method of

securing dirt.

All terraces, levees and sides of drainage

or irrigation canals, and all roads

and highways that are cut shall be

backfilled in one foot lifts and each layer

thoroughly tamped by hand or machine

to provide a good bond between the

undisturbed sides of the ditch and the

new backfill material.

When backfilling on hillsides or sloping

ground, four-foot-high furrows or

terraces shall be provided across the

pipeline ditch to direct the flow of water

into the natural drainage courses and

away from the pipeline ditch. In no

case is surface drainage to be diverted

into channels other than the ones

they followed before the line was laid.

Particular care shall be exercised in

order that all drainage ditches shall be

maintained and left unobstructed to

prevent the backing up of water against

the spoil bank or backfill crown.

Diversion berms / Water bars should

be used wherever ROW ascends or

descends a steep grade to the following

specifications:

4.12.7. Reinforcing

When applicable, contractors are

to reinforce backfilling near or on

river banks, streams, ravines or other

watercourses, irrigation or drainage

ditches, as well as farm terraces with

earth filled sacks, rock riprap or concrete

headwalls. Contractors are responsible

to, at contractor’s expense, to repair

damage to levees, roadways, lanes,

private drives and farm terraces, as

may be caused by settling or washing

through the ditch portion of same, up to

and including the date of acceptance of

the work included herein and through

the one-year warranty period.

4.12.8. Topsoil

Topsoil is considered by OMS to be

the top layer of soil. At times, topsoil

by standard definition will not apply,

in which case the top 2’ of soil will be

considered “topsoil”.

Topsoil shall be segregated in a method

that protects it from overburden, being

trampled, or from mixing with fill dirt.


the separation and quality of topsoil.

Version 1.1

4.13 Leak & Pressure Testing

4.13.1 General

The intent of leak testing is to find

unacceptable faults in a piping system.

If such faults exist, they may manifest

themselves by leakage or rupture; this

may result in catastrophic failure. Piping

systems that rupture may cause sudden,

forcible, uncontrolled movement of

system piping or components, or parts of

components.

A) Location of Equipment

Pipeline systems being tested should be

restrained against sudden uncontrolled

movement from catastrophic failure. All

poly pipe should be located in the trench

and backfilled.

Air compressors should be located a

minimum of 20 feet and no more than

25 feet from the end of the pipe being

tested. Discharge hoses and hard piping

should be secured to the ground in a

manner to restrain it from movement

in the event of a catastrophic failure.

Restraints such as stakes and cables,

straps or tie downs are acceptable. Any

other style of restraint must have OMS

approval.

Pressure recording devices must be a

minimum of 20 feet and no more than

25 feet from the test head, and is to

be located perpendicular to the pipe

being tested. The recorder’s placement

should be out of the whip radius of the

compressor’s discharge hose and/or

hard piping. Chart recorder hoses must

have restraint whip checks installed as

well. The recording device should be

a chart recorder, digital recorder, or

any other recording device approved

by OMS for the length of pipe being

tested. Certifications will be required

for all recorders and gauges for the test

duration.

B) Test Duration

All piping systems are required to be

tested for no less than 8 hours. There

will be no exceptions of pipe footage to

not be tested. The maximum length for

a single tested piping system is 20,000

feet (3.75 miles).

C) Water Sources

Water used for pressure testing must

be from a known clean source, and be

treated with an agent that eliminates the

potential for bacteria growth.

2. Quantity

The quantity of water to be used will be

determined by OMS personnel.

F) Failures

Contractors are responsible for the cost

of labor and materials to repair any

leaks found during the pressure test.

Contractors are responsible for labor and

materials required to isolate the ends of

the pipelines prior to pressure testing.

OMS personnel will be responsible for

purging and placing the pipelines in

service.

G) Depressurizing

After the line has been tested, the

contractor must relieve pressure by

74


means of opening a valve downstream

predetermined by OMS personnel.

H) Dewatering

1. Disposal of Water

Water should be disposed of in

accordance with all local, state, and

federal laws. It is acceptable that water

removed from the pipeline trench be

disposed of on the ROW.

4.14 ROW Clean-Up

4.14.1 Post-Construction Clean-up

It is OMS expectation that construction

materials will be removed from the

ROW as well as any established laydown

areas, roadways, and approved staging

yards. Other restoration agreements may

necessary.

A) Fences

Fences must be restored to original or

better than original condition prior to

project finalization.

B) Gates

Permanent gates must be installed

to ROW agreements, with appropriate

seed for the region in which it is

performed. Consult federal, state, and

local regulations for correct type of seed.

F) Erosion Control

Stake Bales, Straw waddles, or

water bars must be used when the

possibility of slope erosion is imminent.

Near regulated lands (U.S. Corps of

Engineers, Federal, state, Bureau of Land

Management, etc.) Silt fence must be

used to provide a filtration barrier and

protect the environment.

G) Rock Picking

Rocks must be removed from trench

bed if they are larger than 6 inches in

diameter. When rocky conditions exist,

other protective measures will need

to be taken. Never drag pipe on top of

rocky soil.

4.15 Start-up

A) Removal of Isolation Devices

All contractors prior to removing

pancakes, locks, blind flanges, etc. must

follow proper LO/TO procedures for

removing such devices.

B) Opening of Block Valves

Block valves are only to be opened by

OMS personnel. It is imperative that

these valves be operated in such a

Section 4

75

Version 1.1

manner to allow for equal pressure on

both sides of the valve.

C) Suction Line Leak Test

Tank valves must be open and a leak

observation / inspection must be

maintained for at least 30 minutes.

E) Pump to Line Leak Test

1. Pump Start-up

Prior to final production, pump and line

leak tests will be performed by closing

the main line discharge valve. The

pump shall be operated at the MAOP to

ensure all equipment components are

functional, and no leaks exist in the line.

2. Line Purge

When lines are to be purged, OMS

personnel must be present to ensure

the protection of personnel and the

environment. Line purges have many

unique challenges that are specific to the

point at which the release is taking place,

as well as the material and methodology

chosen to safely complete this task.

3. Disposal / Release

All material that originates from an

Oasis owned facility must be contained

properly. Spills of any amount must be

immediately reported to OMS personnel.

4. Trucking

When transporting liquids released

from OMS facilities, proper waste

management protocol must be followed.

Consult OMS personnel for direction on

where and how to properly dispose of

material.

F) System Leak Tests

System leak test will be performed

quarterly, maintaining max MAOP for two

hours while monitoring for any pressure

deviation.

76


Valves must be operated on a quarterly

basis to ensure proper operating

functionality.

5.2 Standards For Work

5.2.1 Complete Systems

Provide pipe, fittings, wiring and

supports to produce complete,

operable systems with all elements

properly interconnected. If a specific

dimensioned location is not shown for

interconnections or smaller system

elements, select appropriate locations

and show them on shop drawings

submittals for review.

5.2.2 Quality of Equipment

It is OMS expectation that contractors

will provide new equipment that is free

of any known operating malfunctions.

This includes materials quality as well.

OMS also requires that contractors

Install equipment that is aligned, leveled,

cleaned and adjusted for satisfactory

operation. Installed equipment must

be in accordance with manufacturer’s

recommendations and industry best

practices so that; connecting and

disconnecting of piping and accessories

can be readily made; and all parts

are easily accessible for inspection;

operation; maintenance and repair.

Oil and lubrication fittings must be

clear of and away from guards, base

and equipment, and within reach from

the ground or operating floor. The

location of all motor connections must

be coordinated in order to properly

orient encased electrical conduits. To

meet these equipment requirements

as furnished, minor deviations from

drawings may be made, however, they

must be approved by OMS personnel.

5.2.3 Manufacturer Recommendations

The recommendations and instructions

of the manufacturers of products used

in the work are hereby made part of

these specifications except as they may

be superseded by other specification

requirements.

5.3 Project Bid Submittal

for control and monitoring requirements.

Manufacturers must design their own

functional electric control devices and

circuitry, in consultation with the specific

elementary control diagrams and other

project specifications, to meet the

equipment control requirements. In many

cases these will need to be National

Electric Manufactures Association

(NEMA) approved for use in flammable

atmospheres.

It is the expectation that supervisors

ensure these system diagrams and

package controls are furnished by the

equipment manufacturer, except the

controls shown in motor control centers

and process controllers, remote control

devices and their interconnecting wiring.

5.5 Materials And Standard Specifications

5.5.1 Materials

OMS expects that designs, fabrication,

and assembling of equipment and

systems be equipped with new materials,
