The Brent oil and gas field lying north east of the Shetland Islands has been a cornerstone of the UK’s hugely successful oil and gas industry. The next step in the life cycle is to decommission the Brent Field’s four platforms and their related infrastructure.
The first of four platforms in the Brent field was lifted from its concrete supporting legs in a single 12-hour heavy lift by a purpose-built twin hulled vessel. The 24,000 tonne Brent Delta platform topside has been sailed to Teesside’s Able Seaton Port yard where it will be dismantled and recycled. Owner Able UK has invested £28m in building Europe’s strongest quayside where the 44m high topside will be dumped to allow a 50-strong team cut it down for scrap. After four years of planning the successful operation 115 miles north east of Shetland by the Dutch vessel Pioneering Spirit is a game-changer for North Sea decommissioning
A major project to decommission the Brent Delta platform is nearing its final stage. Having earlier been lifted on to the Pioneering Spirit transporter ship 115 miles north east of Shetland, it has now been transported to Teesside for a barge transfer to Hartlepool to be scrapped. The 24,000 tonne Brent Delta platform topsides sat on a three-legged gravity-based structure in 140m of water. Shell wants to leave the legs in place. Unusually for a platform, the legs of Brent Delta are made of concrete which makes it much more difficult to decommission than one with steel legs.
