The TAQA Group has commenced work on one of the largest decommissioning project undertaken in the North Sea.
They will be removing the 1988 Brae Bravo platform, east of Sumburgh Head off Shetland. The topside platform weighs 36,000 tonnes, with a jacket substructure weighing 22,500 tonnes.
It will be removed in three separate phases in 2021 and 2022, using two of the world’s largest semi-submersible crane vessels (SSCVs).
It will be the first time these vessels have been used in the North Sea. The ships, named Heerema’s Thialf and Sleipnir, are each greater than 200 metres in length.
All waste materials will be transported to the AF Environmental Base in Vats, Norway for processing, aiming for a 95% recycling or reuse target.
