DELFT, the Netherlands – Allseas will remove and dispose of multiple topsides and jackets from the Valhall area in the southern Norwegian North Sea.
This is the latest contract triggered by operator Aker BP’s frame agreement, signed in 2017, under which Allseas provides transport, installation and removal services for the Valhall field, where water depths are around 70 m (229 ft).
Between 2021 and 2026, the heavy-lift vessel Pioneering Spirit will remove and dispose of the Valhall Drilling Platform (DP) 5,950-t topsides and 4,350-t jacket; the Production and Compression Platform (PCP) 10,900-t topsides and 9,500-t jacket; connecting bridges; and the 1,100-t topsides and 3,500-t jacket from the Hod field, 13 km (8 mi) to the south, which is remotely operated from the Valhall complex.
Hod’s unmanned production platform was the first in the Norwegian North Sea, starting operations in August 1990.
Valhall platform preparations are expected to get under way later this year, continuing into the 2021 lift season.
In addition, Aker BP has invoked an option for the removal and disposal of the Valhall Quarters Platform (QP) jacket and the 2/4-G jacket on the Ekofisk field, 24 km (15 mi) north of the Valhall complex.
Last June the Pioneering Spirit removed the 3,800-t QP topsides, the first of the three original structures (QP, DP, PCP) at Valhall that will go as part of Aker BP’s modernization of the field center.
