Fossil Energy – Decommissioning
TAQA announced it has completed the safe and successful removal of the Brae Alpha West drilling rig 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.
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.
