Major land and sea decommissioning success
A major land and sea decommissioning project took British Nuclear Group another step forward with the recovery of the final sections of redundant Sealine 1 from the seabed adjacent to Sellafield.
The dedicated and skilled team made in excess of 2,500 dives, 700 undersea cuts and filled 55 ISO freight containers to recover the 3,308 metres of redundant steel sealine.
The final sections, along with the cutting station, where sections of the sealines were processed and put into stillages, were lifted from the sea bed and transported to the Low Level Waste Repository for final storage.
Ken Riddell, project manager, said: “The completion of this work is a significant decommissioning milestone and demonstrates British Nuclear Group’s commitment and ability to safely clean up ageing infrastructure.
“The excellent team work between British Nuclear Group and our specialist contractors Land and Marine, Atlas Divers, NNC, Eurest catering and Ashcroft Plant has been key to the success of this project. Regular and open communication with stakeholders has also been a priority. I would like to thank all those involved for their hard work.”
The Sealine recovery project team now enters its final phase - the recovery of the remaining subsea sections of the Temporary Emergency Sealine (TESL).
As the bulk of the project is now complete, the maritime fleet has been partially demobilised. The use of the vessels Ailsa and Jet Star will be retained to continue the recovery of the remaining 1,169 metres of TESL.
Andy Scargill, superintendent for decommissioning, added: “I would like to commend the team on their success. This recovery work demonstrates our skill and commitment to clean-up.”
