Pioneering Spirit sets new offshore lift record

Allseas broke another lift record with its humongous heavy lift vessel Pioneering Spirit, which successfully executed the single-lift installation of the processing platform and utility living quarters topsides in the Johan Sverdrup field, offshore Norway.

Together those topsides have a weight of 44,000 tons. From the start of the 26,000 tons P1 lifting operation on Tuesday morning until the 18,000-t LQ topsides had been lifted into place early Friday morning, it took less than 3 days.

Installation of the P1 topsides is the heaviest single-lift ever executed offshore. On Saturday 16 March, the processing topsides joined Pioneering Spirit in Digernessundet, near Stord, where the 72 meters high and 139 meters long structure was transferred from a barge to Pioneering Spirit.

After waiting out bad weather for 36 hours, the vessel commenced the 11-hour sail to the Johan Sverdrup field, located on the Norwegian Continental Shelf, 160 kilometers west of Stavanger. After final checks and preparations, Pioneering Spirit moved in around the jacket and its motion-compensated lifting beams set down the topsides. The actual installation operation took only 4 hours. The Pioneering Spirit then went back to Stord to pick the utility topsides and repeated the operation.

Pioneering Spirit has installed three of the four platform topsides for phase one of the Johan Sverdrup
development. In June 2018, the vessel successfully installed the 22,000 tons drilling platform (DP) topsides.
In 2022 the vessel will return to the field to install a second processing platform (P2) topsides, weighing
27,000 tons, for phase two of the Johan Sverdrup development.
