Allseas’ dynamically positioned single-lift installation/decommissioning and pipelay vessel “Pioneering Spirit” marked a major milestone by successfully installing the 5500 t test platform topsides on the substructure in the K-13 field in the North Sea on Sunday 7 August.

The motion-compensated topsides lift system beams accurately positioned the topsides, after which installation went exactly as planned.

In the coming days “Pioneering Spirit” will perform DP trials, followed by a series of installation and removal trials with the test platform topsides under varying weather conditions.

After the successful completion of the offshore trials, “Pioneering Spirit” will sail to Norway to remove the 13,500 t Yme platform for Repsol.
