Ithaca Energy has submitted decommissioning plans for its Anglia field in the Southern North Sea.
The normally unmanned Anglia A installation lies around 34miles from the town of Cromer on the Norfolk coast, having ceased production in November 2015.
Ithaca has put forward proposals to the UK government which include removal of the topsides and jacket, weighing a total of more than 1,900 tonnes, to be taken ashore for recycling.
The operator will plug and abandon the subsea wells using a drilling rig, while pipelines will remain in place.
The Anglia “B” manifold, a tieback three miles away, will also be completely removed.
Ithaca acquired an operated stake in gas field in 2010 from GDF Suez (now Engie).
If the plans are approved, the firm proposes to carry out the brunt of the decommissioning work between 2023 and 2025.
Last month Ithaca expanded its presence in the UK North Sea by completing a £1.6bn deal to acquire stakes in 10 producing fields from Chevron.
