commitments, supporting actions, and services delivered must be recognized as expressions

of Quality. We pledge to monitor our performance as an on-going activity and to strive for

continuous improvement. We commit to operate consistent with applicable environmental

legislation and regulations and to provide a framework for establishing and reviewing

environmental objectives and targets.

2.5 SAFETY, SERVICE, AND SOLUTIONS

These three goals define the activities of ABS. They are the bedrock upon which our

commitment to set standards of excellence as one of the world’s leading ship classification

societies is founded. From its inception in 1862, setting safety standards for the marine

industry has been the core commitment of ABS. This is achieved through the establishment

and application of technical standards, known as Rules, for the design, construction and

operational maintenance of ships and other marine structures. Classification is a process that

certifies adherence to these Rules. From its World Headquarters in Houston, ABS delivers

services and solutions to a worldwide client list through a network of local representative

offices in 70 countries.

2.6 REASON TO CLASS

1. Enhanced Safety

The ultimate goal of classification is to promote the safety of the passengers, the crew,

the cargo, the vessel and the environment in which it operates.

2. Protection Of Capital Investment


As a measure of protection of their capital investment, financiers usually require that a

vessel has been designed, built and maintained to appropriate classification standards.

3. Conformance With Underwriting Requirements

Classification signifies that a vessel complies with industry-developed standards. This

is usually mandated by insurance underwriters.

4. Indication Of Due Diligence

Classification is one indication that the shipowner has exercised due diligence during

the construction and service life of the vessel.

5. Indication Of Proper Maintenance

To remain in class, a vessel must undergo periodic surveys to verify that it is

maintained to class standards and in conformance with the Rules.

6. Conformance With Statutory Requirements

In most nations the governing authorities have mandated that certain vessels entering

into their registry be classed.

7. More Than A Century Of Experience

ABS has been in existence since 1862. It has a proven ability to meet the needs of the

shipping industry. The ABS Rules incorporate the knowledge gathered from more than 140

years of operating experience and from the most advanced technological research.

8. Advanced Technological Capabilities

ABS has some of the most respected research and development resources in the

marine industry, and is dedicated to providing greater understanding of marine design and

construction.

9. A Network Of Regional Technical Offices

ABS technical staff are located in Busan, Genoa, Hamburg, Houston, London,

Istanbul, New Orleans, New York, Piraeus, Rio de Janeiro, Shanghai, Singapore, Taipei and

Yokohama, providing fast, local response to client needs.

10. A Network Of Field Surveyors

ABS is able to offer quick, professional, 24 hours a day – seven days a week,

multilingual survey services to clients around the world from an impressive network of more

than 170 offices in 70 countries.

11. Statutory Recognition Of Abs Standards


Many flag States require vessels on their register to be classed with one of a selected

number of approved classification societies. ABS is recognized by every major flag State.

The ABS Classification Rules address many of the standards relating to overall strength,

stability, machinery, safety equipment and pollution prevention contained in the statutory

regulations of those flag States. By classing with ABS, these particular areas of the overall

design could also meet national authority requirements.

2.7 CORE COMPETENCIES

Our engineers offer a spectrum of skills from naval architecture to hydrodynamics to

ergonomics. Our marine surveyors bring experience and professional judgment to their task

of assessing the compliance of a vessel or structure with the ABS Rules and relevant statutory

regulations throughout its life, from drawing board to scrapyard. Our auditors specialize in

management and security systems, particularly those conforming to the International Safety

Management (ISM) and International Ship and Port Facility Security (ISPS) Codes. Backing

these field representatives is an unequivocal commitment to research and development. Our

Technology Department is recognized as a leader of technical innovation in the marine and

offshore sectors.

2.8 ORGANIZATION AND MANAGEMENT

All funds generated from fees for classification services are used solely for the performance

of such services, and any surplus of receipts in any one year is used for the extension and

improvement of such services, including research and development. Management

responsibilities are vested in the Board of Directors the members of which are selected for

their broad experience of the maritime, offshore and insurance industries, and the Council,

chosen from the more than 800 Members of ABS. This membership is drawn from persons

considered to be eminent within their maritime field of endeavor, principally shipowners,

shipbuilders, naval architects, marine engineers, marine underwriters and government

representatives.

2.9 CLASSIFICATION PROCEDURE

Classification is a procedure involving:

the development of standards, known as Rules

technical plan review and design analysis

surveys during construction


source inspection of materials, equipment and machinery

acceptance by the Classification CommitteD

subsequent periodic surveys for maintenance of class

survey of damage, repairs and modifications

2.10 STATUTORY SERVICES

More Than 100 Governments Have Recognizedthe Professional Integrity And

Experience Of Abs by authorizing the classification society to act as a Recognized

Organization (RO) or Recognized Security Organization (RSO). These duties include the

conduct of surveys and the issuance of certificates in accordance with various international

and national maritime Conventions and Codes, such as Load Line, Safety of Life at Sea

(SOLAS), Tonnage, Marine Pollution (MARPOL), ISM Code and the International Ship and

Port Facility Security (ISPS) Code. These governments have recognized that ABS possesses

a global network of exclusive, qualified surveyors and extensive resources in manpower and

technology to conduct the technical reviews, audits and surveys necessary to fulfill the

various Convention requirements. These activities have given ABS a comprehensive

knowledge of national and international maritime regulations. It is able to draw on this

knowledge in advising clients on how best to meet the documentation needs and accurately

apply the criteria


CHAPTER III RESULT

A. UNDERSTANDING OF ABS RULES

3.1 WELDING AND FABRICATION

3.1.1 Preparation of Welding

1. Edge Preparation

The surveyor may accept a welding procedure for build up of each edge that does not

exceed one half the thickness of the member or 12,5 mm (0,5 inchi), whichever is the

lesser.

Case 1

Thickness base metal (t) = 12 mm

Welding gap = 5 mm ( So, maximum welding gap requirement is 3 mm )

Figure 1 : Sketch of Case 1

Procedure Build Up : t x 0,5

: 12 x 0,5

: 6 mm compare with 12,5 (Choose whichever is the lesser)

: 6 mm < 12,5 mm ( Build Up Requirement)

Figure 2 : Build Up Process


Case 2

Thickness base metal (t) = 30 mm

Welding gap = 16 mm ( So, maximum welding gap requirement is 3 mm )

Figure 3 : Sketch of Case 2

Procedure Build Up : t x 0,5

: 30 x 0,5

: 15mm compare with 12,5 (Choose whichever is the lesser)

: 12,5 mm ( Can Not Build Up )

Solution of above problem, Rules with No. 47 IACS Shipbuilding and Repair

Quality Standard For New Contruction and For Existing may be applied.

When 5 mm < Gap 16 mm

Build up gap with welding on one or both sides of preparation, with possible use of

backing strip as necessary, to maximum 16 mm.

When 16 mm < Gap < 25 mm

Welding up with edge preparation or partly renew welding.

When Gap > 25 mm

An insert plate, of minimum width 300 mm, to be welded in place.

According the above rules, the case 2 may be applied Backing Strips (See Figure 4)

Figure 4 : Backing Strips

The Surveyor may accept edge build up in excess of the above, up to the full thickness of

the member on a case-by-case basis, provided the Surveyor is notified of such cases


before the members are welded together. Where plates to be joined different in thickness

and have an offset on either side of more than 3 mm (1/8 in.), a suitable transition

taper is to be provided.

For the transverse butts in bottom shell, sheer strake, and strength deck plating within the

midship portion of the hull, and other joints which may be subject to comparatively high

stresses, the transition taper length is to be not less than three times the offset. The

following of taper procedure are (Figure 5) :

1. Determine the difference thickness of the two plates to be at joint. See Figure A.

T = 7 mm – 5 mm = 2 mm

2. Determine the taper length (L). Based on the rules ABS (Point 2), taper length is 3 x

T = 6 mm. See Figure B

3. Later, the difference between the plate thickness associated eith the length of taper.

Eventually, cutting the plates as shown C.

Figure 5 : Taper Process

2. Run-on and Run-off Tabs

Run-on and run-off tabs are to be designed with the following purpose :


1. To minimize the possibility of high-stress concentrations and base-metal and weld-

metal cracking.

2. The result of welding can be neat

3. Stability of welding process can be maintained. Because run-on and run-off tabs will

be to bind the both plates before continues welding (joint)

Figure 6 : Run on and Run off Tabs

3. Cleanliness.

All surfaces to be welded are to be free from moisture, grease, loose mill scale,

excessive rust or paint. Primer coatings of ordinary thickness, thin coatings of linseed oil, or

equivalent coatings may be used, provided it is demonstrated that their use has no adverse

effect in the production of satisfactory welds. Slag and scale are to be removed not only from

the edges to be welded but also from each pass or layer before the deposition of subsequent

passes or layers. Weld joints prepared by arc-air gouging may require additional preparation

by grinding or chipping and wire brushing prior to welding to minimize the possibility of

excessive carbon on the scarfed surfaces. Compliance with these cleanliness requirements is

of prime importance in the welding of higher-strength steels, especially those which are

quenched and tempered.

4. Tack Weld

Tack weld is similar with intermitten welding. The fungtion of tack weld is to position

and to lock with temporary two plates before joint with continues welding. The several

requirement for tack weld process are :

1. To made with the same grade of filler metal

2. To need be removed, if after examination to be thoroughly clean and free from crack

or other crack.


3. Preheat may be necessary prior to tack welding when the materials to be joined are

highly restrained. Special consideration is to be given to use the same preheat as

specified in the welding procedure when tack welding higher-strength steels.

3.1.2 Production Welding (Especially Preheat Process)

Preheat is giving heat before welding process plates. In all cases, preheat and

interpass temperature control are to be sufficient to maintain dry surfaces and minimize the

possibility of the formation of fractures. The preheat requirements is :

1. When welding is performed under high humidity conditions or when the temperature

of steel is below 0°C (32°F), the base metal is to be preheated to at least 16°C (60°F)

or temperature appropriate to the alloy and the thickness, whichever is higher.

2. When preheat is used, the preheat and interpass temperatures are to be in accordance

with the accepted welding procedure and to the satisfaction of the Surveyor.

3.2 DEAD SHIP AND BLACKOUT

3.2.1 Dead Ship

a. The main propulsion plant, boilers, and auxiliary machinery are not in operation

due to the loss of the main source of electrical power

b. In restoring propulsion, the stored energy for starting the propulsion plant, the main

source of electrical power and other essential auxiliary machinery is assummed to

not be available.

3.2.2 Blackout

Blackout situation means the loss of the main source of electrical power resulting in

the main and auxiliary machinery to be out of operation.

3.15 RADIOGRAPHIC TEST

3.15.1 Reference

ABS Guide For NONDESTRUCTIVE INSPECTION OF HULL WELDS

3.15.2 Purpose of Nondestructive Test

1. Generally, the purpose of NDT (Non Destructive Test) is to examine the welding joint to

ensure no welding defects without damaging the overall structure of the material.

2. NDT is divided in several types such as :

a. MPI (Magnetic Particle Inspection) and PT ( Penetrant Test) is to be used for

investigating the outer surface of welds or may be used as a check of intermediate

weld passes.

b. Radiographic test (RT) and ultrasonic test (UT) is to be used for investigating overall

of the weld cross section, because Radiographic Test (RT) and Ultrasonic Test (UT)

is able to evaluate the every boundary SIM Joint ranging from the surface to the

inside.

3.15.3 Defenition

An NDT method that utilizes x-rays or gamma radiation to detect discontinuities in

materials, and to present their images on recording medium

3.15.4 Advantages and Disadvantages

a) Advantages

1. Both surface and internal discontinuities can be detected

2. Significant variations in composition can be detected.

3. It has a very few material limitations.

4. Can be used for inspecting hidden areas ( direct access to surface is not required )

5. Very minimal or no part preparation is required.

6. Permanent test record is obtained.

7. Good portability especially for gamma-ray sources.

b) Disadvantages

1. Hazardous to operators and other nearby personnel because radiation is so

dangerous

2. High degree of skill and experience is required for exposure and interpretation.

3. The equipment is relatively expensive (especially for x-ray sources).

4. The process is generally slow.


5. Highly directional (sensitive to flaw orientation).

6. Depth of discontinuity is not indicated.

7. It requires a two-sided access to the component.

3.15.5 Radiography Testing Sketch

Figure 63 : Radiographic Test Sketch

3.15.6 Time of Inspection

1. Minimum 48 hours of interval time for steel 415 Mpa.

2. Minimum 72 hours of interval time for steel 620 Mpa

At the discretion of the Surveyor, 72 hours interval may be reduced to 48 hours for

radiography testing (RT) or ultrasonic testing (UT) inspection

3.15.7 Surface Condition

Before Radiographic Test (RT), Slag shall be removed from all completed welds.

All welds and adjacent base metal shall be cleaned by wire brushing or by any other

suitable means prior to inspection.

3.15.8 Technique

Steel welds and structures can be radiographed by utilizing either gamma rays or x-

rays. Aluminum alloys can be only radiographed by x-rays. Section 2, Table 1 below

summarizes the methods to be used.

Table 14 : Material and Inspection Method


3.15.9 Radiography Quality

The radiographic quality level is a combination of radiographic contrast and

definition.

Radiographic contrast is the difference in density between two adjacent areas on the

film. It is primarily controlled by the energy level of the radiation source and type of

film used. The fastest speed of film that provides the required quality level and

definition may be used. The density contrast curve for the film, which is provided by

film manufacturer, shall have a minimum of 5:1 ratio with the lightest density not less

than 2.0.

Radiographic definition refers to the sharpness of the image outline and is controlled

by geometric unsharpness.

Geometric Unsharpness

Table 15 : Geometric Unsharpness

3.15.10 Film Identification

When more than one film is used to inspect a length of weld or a complete

circumferential weld, identification markers are to appear on each film, such that each

weld section reference marker location is common to two successive films to establish that

the entire weld has been inspected.


Figure 64 : Film Identification

3.15.11 Source to Film Distance

Figure 65 : Source to Film Distance

3.15.12 Film Length and Width

Film shall have sufficient length and shall be placed to provide at least 12 mm (½ in)

of film beyond the projected edge of the weld. Film widths shall be sufficient to depict all

portions of the weld joints, including heat-affected zones (HAZ), and shall provide sufficient

additional space for the required hole-type IQIs or wire IQI and film identification without

infringing upon the area of interest in the radiograph.

3.15.13 Image Quality Indicator (IQI)

IQI is divided in two types : hole type and wire IQI

a) Hole Type


The size of the shim is to be a minimum of 3 mm (1/8 in) larger than the plaque IQI. The

IQI is to be placed parallel to the longitudinal axis of the weld. The position of the IQI is to

be such that the image of the IQI and shim is not to be projected within the area of interest

Figure 66 : Hole Type IQI

b) Wire IQI

1. There are presently two types of wire IQIs in use. Both consist of parallel strips of

wires of varying diameters encased vertically in a clear, sealed plastic pouch.

2. The ASTM IQI consists of six (6) wires, see Table 5, with the thickness of each wire

increasing from left to right.

Table 16 : ASTM Wire IQI Designation, Wire Diameter and Wire Identity

Figure 67 : Wire IQI


3. The ISO IQI consists of seven (7) wires, see Table 6, with the thickness of each

decreasing from left to right.

Table 17 : ISO Wire IQI Designation, Wire Diameter and Wire Identity)

Figure 68 : ISO Wire IQI

4. The ASTM or ISO IQI is to be placed perpendicular to the longitudinal axis of the

weld, such that the projected image is within the weld image. The required sensitivity

is achieved when the required diameter wire image is visible within the weld image.

5. IQI Selection

Selection of the applicable IQI quality level is to be based upon the plate thickness

plus allowable weld reinforcement (See Table 18 and Table 19)

Table 18 : Hole Type IQI Selection


Table 19 : Wire IQI Selection

c) Location of IQI

Regardless of the IQI design, the IQI is to be placed on the side of the weld facing

the source of radiation (source side) in the worst geometrical position which is required at

either end of the applicable length of weld under inspection

If an IQI cannot be physically placed on the side of the weld facing the source of

radiation, the IQI may be placed in contact with the back surface of the weld. This is to be

indicated by the placement of a lead letter “F” adjacent to the IQI.


Figure 69 : Location of IQI

3.15.14 Radiographic Film Interpration

Film interpretation and evaluation are only to be undertaken by qualified and certified

Level II and/or Level III industrial radiographers.

For film viewing facilities, viewing and interpretation of finished radiographs are to

be in an area that is clean, quiet, and provides subdued background lighting.

Figure 70 : Situation of Viewing and Interpretaion Film Process


A = RT company D = IQI Type G = Type of welding

B = Owner company E = IQI Position H = Multiple Film

3.15.16 Additional

If RT is the primary method of volumetric inspection and the minimum extent of RT

coverage meets the extent requirements to the surveyors satisfaction, then any supplementary

UT proposed is permitted to be to a minimum check length of 500 mm (20 in.)

3.15.17 Surface Vessel

The minimum extent of radiographic inspection within the midship 0.6L of surface

vessels is to be governed by the following equation :

3.15.18 Location of Radiographic Inspection

1. General

certificates. but the difference between the two lies in the position. The different lies in its

position. If the pressure gauge connet to the pipe and installed near the pipeline. As for the

chart, is also connect to the pipe, but the position was placed about 5 meters of the pipe.

Actually, the use of charts in hydrostatic test for pipe class 1 is for safety reason. Because the

pressure used during the test is high, then checking the conformity of pressure based on the

design testing and pressure testing can be done at a relatively far distance (5 meters). In

addition to the value of pressure used, in the chart there is also a testing time

Figure 84 : Chart


3.17.4 Procedures

1. To connect between pressure gauge, pressure testing pump and chart.

Figure 85 : The Circuit of Pipe During Hydrostatic Test

2. Fill in pipe with the water.

3. Fill in pipe with the water high air pressure. Capacity pressure used depends on the design

of pressure value and test pressure value. Pressure values used can be seen on the chart.


Figure 86 : The Pressure on Chart

4. Wait for see the result (minimum 5 minutes). If the pipe is able to withstand the pressure

exerted, the pipe structure will not be changed (example bent and leak). In addition, if the

pressure value on the chart has not changed (decreased) then it is certain that the pipe

does not leak.


From the result visual inpection of Hydrostatic Test, not found changes in the pipe

structure. Beside that, the value of chart don’t change. Base on situation that, it can be

ascertained that the pipes do not leak.

3.21 BOLLARD PULL TEST

3.21.1 Defenition

A bollard pull is a test or rather the results returned by tests used to establish the

maximum pulling force working watercraft can exert. Mooring bollards are often used as an

anchor points which is where the tests get their name. When maximum thrust is applied to the

boat's engines, the amount of pulling power exerted on the cable is read off the gauge.

3.21.3 Static Bollard Pull Test Requirement

a. Test Condition Requirements

1) Owner Requirements :

a) Prior to conducting the test, the owner has submitted a written correspondance :

Requesting ABS attendance

Starting the propeller are approved by ABS for vessel

Starting the owner is satisfied with the structural adequency of the vessel’s

towing hawser, towing winch, two bitts or towing arrangement

b) The owner has provided a copy of the stability letter stating the vessel’s towing

capability any towing restrictions.

2) Vessel Data :

a) Main engine :

Owner has verified all main engines are not adjusted to operated in the overload

condition during the test.

Over speed setting for the main engines verified by the Surveyor prior

commencing the bolard pull test.


3) Environment/Condition :

a) The depth of water under the keel in testing area should be at least twice the

vessel’s draft amidship.

b) The distance from the stern of the towing vessel to the bollard (fixed point) should

be at least two ship length (LOA)

c) Wind speed should be 10 mph (1 knot = 1,150 mph) or less, or such, that it does not

measurably affect the bollard pull result.

d) If current exceeds 1 knot, its effect is to be substacted from the bollard pull by

either :

Direct measurement of drag effect (pulling direction downstream) and reduction

of bollard pull accordingly; or

Conducting pull test both upstream and downstream and averaging the result

e) The dynamometer (load cell) is :

Calibrated and suitable for use in horizontal position. It should be fitted with

swivels or should be torque insensitive, such as a hydraulic dynamometer.

It should be easily read from a safe location or a remote readout should be

provided.

The dynamometer should be located at the ashore end of the tow hawser.

f) The towing vessel should be on an even keel or trimmed to the intended operating

condition in tow.

g) The draft of the towing vessel should be equal to or deeper than ballast condition,

but need not be down to the summer load line mark.

4) Duration of Bollard Pull :

The static Bollard Pull should be computed as the average of evenly spaced load

cell recordings taken over a sustained pull interval of three to five minutes.

5) Miscellaneous Item :

During the test, one surveyor is located in the vessels engine room and one

surveyor is located at the shore station.

b. Tets Preparation


1) Re-check all load cell unit ; telemetry indicator and load cell. Ensure all equipments in

proper connection, sufficient power and function able. Beside that, Surveyor must be

review calibration certificate of the load cell in use.

Figure 107 : Wire Connect To Towing (Left) and Wire Connect To Towing (Right)

2. Smoothly extend wire rope to avoid instantaneous spike tension load reading and

maintain towing vessel in steady condition.

3. Gradually increased main engine load to maximum continuous rpm (MCR 100%)

Figure 108 : RPM Reading Process in Engine Room

4. Continuous load cell reading from ashore should be informed to the onboard bollard pull

test officer for reference to determining vessel steady condition with continuous steady

tension load reading indication.

5. Confirmation is required from onboard bollard pull test officer to the ashore officer to

start measurement & recording the tension load reading.

6. Duration of bollard pull test measurement is 3~5 minutes

7. Load tension reading displayed informed continuously to the onboard by ashore officer.


8. When measurement completed, the ashore officer should be informed to onboard officer..

9. Testing condition when tension load recording should be recorded by onboard officer and

informed to ashore officer for documentation, i.e.:

Wind speed

Current speed

Towline length

Water depth under keel
