This Technical Manual covers the general usage and maintenance of this equipment. This equipment

operates under high pressure. As such a great deal of care must be taken to ensure the safety of those

operating this equipment as well of those in its vicinity. It is critical that an adequate maintenance

regime is kept and that personnel fully understand the purpose and the operation of this equipment

before taking it out into the field.

The procedures described herewith are not intended as a replacement to local laws or regulations, nor

your companies’ policies and procedures. If in any doubt contact your local authority, company

superior or a Hunting Energy Services (Well Intervention) representative.

Failure to perform routine maintenance checks could invalidate manufacturer warranty.




1.0 Health and Safety

1.1 General

Personnel using this manual to perform maintenance should have basic training in the following

disciplines:

• Manual handling

• MSDS and COSHH

• Use of workshop equipment

• Use of hand tools (PUWER)

Other basic courses may be required depending on regulations in the location/region that the

equipment is being used.

Safety is everyone’s responsibility, anyone can stop an operation should they deem an act unsafe no

matter what their position is within an organisation.

By following this document, using hand tools correctly, and following working practices the risk of

injury will be reduced to negligible.

CAUTION

• Read service manual before operating

• Observe all safety precautions

• This system is capable of producing high fluid pressures - appropriate considerations are

required

• Check that only qualified personnel are in immediate area around equipment

• Suitable PPE must be worn at all times

• Do not try to tighten or loosen connections under pressure

• Do not weld, file or use metal stamps on the pressure equipment - these can create cracks

which could result in structural damage/failure

• Do not attach anything to this equipment unless you are sure of its pressure rating

• Watch for trapped pressure. Bleed off fully before breaking down tool

Observe the maximum allowable operating pressure of all system components.

Observe the operating conditions of components.

Never stand under suspended loads or in the lifting area!




1.2 Precautions

A competently deemed person must be in attendance when performing maintenance on this

equipment. To be deemed competent the individual should have received training on the subject

followed by being observed performing the tasks to the required standard over a time period.

Personnel competence criteria are defined by the technician’s employer.

Hand tools that have not been maintained can lead to accidents; therefore all equipment must be

inspected before use.

1.3 PPE

Basic personal protective equipment must be worn at all times during the maintenance procedures.

There may be the need to use more specific items when using specialised tools, these rules must be

followed to reduce risk of injury. Basic items deemed by Hunting for maintenance personnel are as

follows:

• Safety footwear

• Safety glasses

• Hand protection

• Long sleeved coverall

Some workshop regulations deem that hard hats / bump caps and hearing protection must be worn in

maintenance shops, these will be defined by the policy owner. If working in the field, all of the above

items may need to be worn at all times, once again, this is defined by the company / client’s policies.

1.4 Pressure Control

Working with pressure exposes personnel to one of the greatest risks in our industry hence all

personnel must have received formal training on this subject. Company / Client pressure guidelines

must be adhered to with no deviation from the policies. Personnel performing pressure tests must

observe regulations concerning pressure test bays and operating instructions for pumps. All equipment

must be rated for the pressure being applied and certified.




2.0 Description

The External Dimple Coil Connector is an external type connector for coil tubing. A Dimple Jig is

first used to imprint the dimples on the coil. The External Coil Connector is then fitted on the OD of

the coil. Locking screws are then located through the Connector onto the dimples to fasten the

Connector onto the coil.

3.0 External Dimple Coil Connector Components:

Item # Description

1 External Dimple Connector

2 Coil

3 Hex Soc Set Screw

4 O-Ring




4.0 Make Up Procedure

• The coiled tubing should be dressed prior to being dimpled with the External Dimple Jig

Assembly and should be cut square and chamfered with a file. Measure length inside Dimple

Jig (4) and mark Coiled tubing to match

• Push Dimple Jig (4) onto dressed coiled tubing

• Marked length should sit flush with Dimple Jig end face

• If marked length is not flush, use slide Hammer (3) to knock on end of Dimple Jig until line is

flush with end face

• Turn Dimpling Screw (5) a couple of turns. Repeat for Dimpling Screw at 180 degrees.

Repeat this procedure until all 12 off screws are inserted

• Using an Allen Key fully tighten Dimpling Screw onto coil until Dimpling Screw Head

shoulders out on Dimple Jig OD. Repeat this process for all 12 off Dimpling Screws

Note: Dimpling Screw Head must bottom out on OD of Dimple Jig.

• Remove all Dimple Screws from Dimple Jig (4) and remove from coiled tubing

Note: If Dimple Jig cannot be pulled from the coiled tubing use Hammer Slide and knock

against face of Top Sub (1).

• Ensure that the O-Rings (4) are fitted in the bore of the Connector (1) as per assembly

procedure

• Measure length inside Connector (1) and mark Coiled tubing to match

• Ensure a liberal coating of grease is applied to the inside of the Connector (1) & the OD of the

coiled tubing

• Push Connector onto coiled tubing and line up screw holes of Connector (1) with the dimples

on coiled tubing

• Marked length should sit flush with Connector end face

• If marked length is not flush, use slide Hammer (3) to knock on end of Connector until line is

flush with end face

• Insert Set Screws (3) into Connector (1) landing out in the dimples on the coil

• Pull test and pressure test as per operational requirements

Note: Refer to Assembly drawing for tool end connections in Appendix 1.




5.0 Disassembly Instructions

Generally, if the connector is to be disassembled it will still be attached to a piece of coil. If this is the

case the following applies, if not disassembly is simply the reverse of the assembly procedure.

Item numbers called out in this document correspond with assembly drawings in Appendix 1.

• Remove all Set Screws (3) from the Connector (1)

• If for any reason it is not possible to remove the connector from the coil, simply cut the coil

approx. 10” from the Connector (1) and ship back to workshop for Disassembly

• Remove O-Rings (4) from Connector (1). (Typ. 2 places)

6.0 Assembly Instructions

Clean and inspect all parts prior to assembly. De-burr any rough edges and buff all seal surfaces

where required. All seals and sealing surfaces should be lubricated with multipurpose grease and

threads should be coated with an anti-seize compound prior to make-up.

Item numbers called out in this document correspond with assembly drawings in Appendix I.

• Fit O-Rings (4) into the Connector (1). (Typ 2 off places)

• Insert Set Screws (3) into the Connector (1). (Typ. 12 places)




7.0 Maintenance

• Completely disassemble all components and clean thoroughly before inspecting for wear,

corrosion or damage

• Threaded connections must be inspected thoroughly

• Elastomers showing any wear should be replaced

BEFORE EVERY JOB:

• Certification should be checked to confirm equipment compliance with operational needs

• Confirm all component pieces are tightened correctly

• Pressure test and function as per operational requirements

AFTER EVERY JOB:

• Disassemble, clean and inspect all components

• Inspect all seals and sealing surfaces, replace as necessary

• Check all threaded connections

• Reassemble as per the assembly instructions

WHEN CHECKING COMPONENTS FOR DAMAGE OR WEAR:

Particular attention should be paid to:

• Seals

• Threads

• Set Screws

Lubricate all seals and install new seals if required.

Many companies have established preventive maintenance programs that require re-certification of

the equipment on a quarterly, semi-annual, or annual basis. These policies / procedures can only

supersede Hunting recommended maintenance if they are more intensive.

If in doubt contact your local Hunting office for clarification.

7.1 Recommended Lubricants/Chemicals:

• Multipurpose Grease

• Dry Film Lube




8.0 Troubleshooting

9.0 Recommended Spares/Accessories

Re-dress kits are available for all External Dimple Coil Connectors. For part number refer to Assembly Drawing in Appendix 1.
