Allseas has been awarded a major decommissioning contract by TAQA UK for the removal and disposal of multiple Northern North Sea (NNS) facilities.
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 (UKCS) decommissioning contract scope to date.
Allseas’ task is to remove four platform topsides, three steel supporting jackets and transport to a suitable onshore yard facility for dismantling, with the aim of reusing or recycling 95 percent or more of the materials.
The platforms are located close to each other, approximately 100 km north-east of Shetland, in water depths ranging from 150 to 167 m.
All structures will be lifted and removed to shore as single units using Allseas’ heavy lift vessel Pioneering Spirit. Platform removals are planned post 2025.
