Subsea decommissioning is a growing part of our activities, especially in Northern Europe, where an increasing number of subsea fields require decommissioning and abandonment. We have gained significant experience in the decommissioning of subsea umbilicals, flowlines, and risers over the years, including solid knowledge of local regulations closely controlling such activities in the North Sea. This enables us to support our clients from both technical and regulatory perspectives.

Our scope of UFR decommissioning services includes:

• Flushing/Cleaning of risers and flowlines using mechanical pigs, foam pigs, or gel pigs pumped from topside in a closed loop or in an open loop using Subsea Pig Launcher/Receiver (SPLR).


• Flushing/Cleaning of risers and flowlines using density-controlled pigging gel pumped from topside, from a support vessel using a downline, or by bull-heading into wells.


• Flushing/Cleaning of umbilicals' hydraulic and chemical lines by high-pressure pumping from topside, using eco-friendly preservation fluids as a priority.


• Post-flushing/Cleaning fluid sample analysis to ensure compliance with local regulations.


• Subsea cutting and surface recovery of umbilicals, flowlines, and risers.
