£2 million well abandonment programme

Paul Boughton

Marine Subsea UK Ltd has been awarded a series of contracts worth more than £2 million to carry out a multi-client well abandonment programme for operators in the North Sea.

In a campaign designed to spread the mobilisation and transit costs associated with decommissioning activity, Marine Subsea UK will use its specialist light well intervention vessel Sarah to plug and abandon a single Category 2.2 and four Category 1 suspended subsea wells, spread across a large area of the North Sea.

The contracts are with a number of oil and gas operators including DNO, Bayerngas UK and Tullow. Work is scheduled to start in July with mobilisation in Aberdeen.

Marine Subsea UK will lead the project to perforate, cement and carry out abrasive severing and recovery of the wells. The company will also be responsible for the recovery and disposal of residual oil-based muds.

Marine Subsea UK offers a range of subsea well intervention, decommissioning and construction support solutions to the global subsea oil and gas industry.

Alasdair Cowie, Managing Director of Marine Subsea UK said: “We bring significant cost savings using this multi-client approach, helping to cut the expense of subsea decommissioning. We are delighted to be awarded these high profile North Sea contracts, which recognise our track record and safety standards. We are well positioned to support operators in the North Sea and globally, to carry out decommissioning to the highest standards.”

Marine Subsea operates a fleet of vessels including two multipurpose/intervention vessels, five offshore support units and one semi-submersible crane vessel.

The Sarah is an Ulstein SX121 DP3 (dynamic positioning) vessel that is capable of operating in depths of 3,000 metres. The vessel has deck capacity of 1,470 metres“ and main features include a tower, main crane and two heavy duty workclass ROVs.
