Marking its latest development as a 'decommissioning milestone', Perenco UK announced that it has successfully completed the plug and abandonment of three subsea wells at the Gawain field in the UK Southern North Sea.
Challenging decommissioning campaign
In a campaign that added up to 160 days and included more than 340 air dives, the workforce made sure to remove all associated subsea infrastructure as well. Post decommissioning surveys will continue till the end of the year so that the seabed is left spotless.
Given the challenging winters in the Southern North Sea, the team was able to tackle the project unscathed as they worked considering the health, safety and environment factors. Workers were backed by specialist contractors and a jack-up vessel equipped with an air-based diving, and remotely operated vehicle (ROV) spread to allow for rig-based diving.
Perenco UK SNS Managing Director, Jo White, said, “The completion of this significant project shows the commitment Perenco has to effective and efficient decommissioning of our SNS assets. It highlights the expertise of our specialist teams, with a mindset of developing innovative approaches, while maintaining a strong focus on health, safety and the environment.”
