Our project experience in Decommissioning

Anasuria Project

Case Study: North Sea Anasuria project

Decommissioning project for a major Operator including recovery, cutting and disposal of a dynamic umbilical .

Phase 1

• Detailed engineering

• Offshore recovery procedures

• Disposal management planning

Phase 2

• Supply of personnel and equipment

• Offshore recovery of a 6” umbilical

• Transport reel + product to WallsendDisposal Site

Phase 3

• NORM testing

• Flushing and nitrogen purging

• Off‐spooling of used product

• Cutting product

• Waste management control

• Recycling product

Phase 2 Offshore Campaign: Dynamic control umbilical

Length 955 ft

OD 6.5“

Phase 2 Offshore Campaign: Full spread of equipment

Phase 3 Onshore Campaign: Contamination and testing

• NORM testing conducted prior to offloading

• A 33 foot umbilical section was collected behind the bend stiffener for product testing

Phase 3 Onshore Campaign: Planning

E3 & E4 Signal Cores

Phase 3 Onshore Campaign: Cutting and disposal

• Significant safety precautions to ensure no personnel injury or environmental pollution

• Plastic sheeting is applied at cut ends to capture any remain fluids

Results and Value Proposition

• Executed both the offshore and onshore campaigns safely for our people and the environment

• Developed capability to offer turnkey solution for disposal with an integrated supply chain 

• Capable of managing multiple interfaces on behalf of the customer

• Received licensing to perform disposal at Peterhead site for future projects.

Case Study: Recovery of bundled systems

• 9 different bundled line types• Limited deck space• Full contamination control
