Perenco completes subsea decommissioning campaign at Gawain field in UK North Sea

March 12, 2024

(WO) – Perenco UK announced a decommissioning milestone with the successful completion of the plug & abandonment of three subsea wells at the Gawain field in the UK Southern North Sea, including the removal of the associated subsea infrastructure.

With a strong focus on health, safety and the environment, the project was completed without incident, despite the challenging conditions encountered when operating in winter in the Southern North Sea.

Perenco UK achieved this by working in collaboration with specialist contractors and utilizing a jack-up vessel equipped with an air-based diving and ROV spread to allow for rig-based diving.

The campaign lasted over 160 days and included over 340 air dives, with the completion of this project marking a key moment for Perenco UK and the wider Perenco group. Works will continue in 2024 with post decommissioning surveys to ensure the seabed is left clear and clean.

Perenco UK SNS Managing Director, Jo White, added, “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.”
