Offshore installation and decommissioning contractor Allseas has secured a contract with TAQA UK for the removal and disposal of
several Northern North Sea (NNS) facilities.
Aberdeen-based TAQA manages the UK North Sea exploration and production portfolio for UAE-headquartered utilities and energy group Abu Dhabi National Energy Company (TAQA).
The engineering, preparation, removal and disposal (EPRD) contract comprises TAQA’s Eider Alpha, Tern Alpha, North Cormorant and Cormorant Alpha platforms.
"The combined weight of the topsides and jackets to be removed is around 114,000 tonnes, making this the largest single offshore UK Continental Shelf decommissioning contract scope to date," Allseas said. The financial details were not disclosed.
Allseas is responsible for the removal of four platform topsides and three steel supporting jackets and transporting them to a suitable onshore yard facility for dismantling, with the aim of reusing or recycling 95% or more of the materials.
The platforms are located close to each other, approximately 100 kilometers northeast of Shetland, in water depths ranging from 150 to 167 meters, Allseas said.
According to Allseas, all structures will be lifted and removed to shore as single units using Allseas’ heavy lift vessel Pioneering Spirit.
"Allseas is proud to be TAQA’s contractor for this major decommissioning contract and looks forward to close collaboration with TAQA to prepare and execute the safe and sustainable decommissioning of these NNS assets. Platform removals are planned post-2025," Allseas said.
