Allseas Wins Contract for Multiple Decomm Jobs

Pioneering Spirit returns to Valhall area to remove three complete platforms and two jackets between 2021 and 2026. Allseas has been awarded a contract by Aker BP for the removal and disposal of multiple topsides and jackets from the Valhall area in the Norwegian North Sea.

The contractis the latest award triggered by Aker BP under the terms of the frame agreement signed with Allseas in 2017 to provide transport, installation and removal services for the Valhall oil field.

Work comprises removal and disposal of the Drilling Platform (DP) 5,950t topsides and 4,350t jacket, and Production and Compression Platform (PCP) 10,900t topsides and 9,500t jacket from the Valhall complex, plus the 1,100t Hod topsides and 3,500 t jacket from the connected Hod field, 13km to the south. Allseas’ heavy lift vessel Pioneering Spirit will execute the work between 2021 and 2026. Water depth at the field is approximately 70m. Platform preparations are scheduled to commence later this year, continuing into the 2021 lift season. In addition, Aker BP have invoked the option for the removal and disposal of the Valhall Quarters Platform (QP) jacket and the 2/4-G jacket on the Ekofisk field, 24km north of the Valhall complex. This option was associated with the 2017 award for the removal and disposal of the QP topsides, removed by Pioneering Spirit in June 2019. The QP topsides was the first of the three original structures (QP, DP, PCP) at Valhall to be removed as part of the modernisation of the Valhall field centre by Aker BP. Hod is remotely operated from Valhall and was the first unmanned platform in the Norwegian sector of the North Sea when production started in August 1990.
