alternatively via Supergrip (UK) supplier nut runner and torque tool. Details of which

are presented later in this presentation.

• Hydraulic installation tool is required to close the clamp.

• The tool lands on the damaged pipeline and is activated by either the ROV hydraulic system,

from a downline reel from the installation vessel or subsea hydraulic power unit

• All function are performed through a hot stab / receptacle interface and ROV activated

valves.

• The tool enables controlled linear closing of the clamp ensuring all joint seals are correctly

seated prior to clamp activation

Dependent upon the clients commercial strategy there are two options for activating

the pipeline repair clamps once they have been closed around the pipeline by the

installation tool:

Option-1: traditional subsea tensioners

Option-2: Supergrip supplied subsea activation tools

Considerations:

1. Subsea tensioners provide a quicker more efficient installation subsea as they are

all activated simultaneously from a suitable hydraulic power unit. However the

capital cost of the equipment is greater due to the quantity of tensioners and

hoses / fittings required.

2. The subsea activation tools are a lower cost solution when purchasing the

equipment however the time to activate the clamp subsea is slightly increased as

each individual bolt it tensioned separately.

Ref: A-00203-DOC-002

Standard subsea tensioners Standard subsea tensioners

• Nut runner is used to provide initial activation of the clamp. This provide high flow low

torque which enables the clamp seals to be partially activated in a quick manner.

• Once all bolts have been partially activated the torque tool is then applied to provide

the final high torque requirement to fully activate the clamp

• The torque tool is designed with multi-reactor points which engage with adjacent

bolts.
