Abu Dhabi National Energy Company PJSC (TAQA), one of the largest listed integrated utility companies in the Europe, the Middle East and Africa region, today announced it has completed the safe and successful removal of the Brae Alpha West drilling rig (Rig 1) and the Brae Bravo upper main jacket in the Northern North Sea.
The operation, which was the latest in TAQA’s extensive UKCS decommissioning programme, involved the removal and transport of more than 12,000 tonnes of material from the Brae field in the UK North Sea.
The HAF Consortium, Heerema Marine Contractors and AF Offshore Decom, were contracted to execute the operation on behalf of TAQA.
The Heerema-operated Sleipnir semi-submersible crane vessel first removed the 1,000 tonne Brae Alpha Rig 1, in a single lift on 20 June.
Sleipnir then moved to Brae Bravo to remove the 11,000-tonne upper main jacket. This forms part of TAQA’s decommissioning obligations and follows the removal of the Brae Bravo topsides modules and flare bridge, jacket and tower last summer – one of the largest topsides removals in the UK North Sea.
The operation was completed with zero health and safety incidents.
Both Rig 1 and the Brae Bravo jacket have been safely offloaded at the AFOD Environmental Base in Vats, Norway, and are being processed with the aim of reusing or recycling 95% or more of the material, which is expected to be completed in 2023.
Commenting on this milestone, Donald Taylor, TAQA Managing Director for Europe, said: “TAQA’s extensive late-life portfolio positions us at the forefront of decommissioning in the UK. By adopting valuable lessons learned during last year’s successful Brae Bravo topside removal campaign, we are continuing to develop our skills and capabilities supporting the transition from operations to removals and disposal.
“The coming years offers some of the most interesting challenges and opportunities for our workforce and wider industry. TAQA is proud to pioneer this change while maximising the value of our assets and playing a valuable role in the energy transition.”
Prior to cessation of production in 2018, Brae Bravo produced more than 500 million barrels of oil equivalent over its 33-year life. Brae Alpha began production in 1983 and continues through present.
