Allseas’ singlelift installation/decommissioning and pipelay vessel “Pioneering Spirit” marked another milestone on 2 June 2018 with the safe and successful installation of the 22,000 t Drilling Platform topsides for Equinor’s Johan Sverdrup development on the Norwegian continental shelf.

This was the first platform installation job performed by Pioneering Spirit, and the heaviest installation ever executed in a single lift offshore to date.

Pioneering Spirit’s motioncompensated topsides lift system beams accurately positioned the topsides on an eightlegged steel jacket standing at 110 m water depth, after which the installation went exactly as planned.
