Allseas’ Pioneering Spirit, the largest construction vessel, has recently received its new jacket lift system built to install and remove entire jackets up to 20,000 tonnes in a single lift. The upgrade has already been completed and the vessel has recently completed the first commercial lift with its new JLS technology.

Through a video series Allseas has provided an insight into the engineers and crew on board Pioneering Spirit working around the clock to install the main beams and commission integrated sub system of the Jacket lift system, to reach the next major milestone: upending the 170 metre long beams for the first time. This was a challenging operation requiring the upend system, derrick hoist and water ballast systems to work simultaneously for the first time.

Equipped with unique motion compensated, single-lift technology, Pioneering Spirit can lift and transport entire platform topsides and offshore substations in one piece, significantly reducing the amount of offshore work, moving it onshore where it is safer, more cost effective and poses less environmental risk.

The jacket lift system that the vessel is being upgraded with eliminates the need for barges, offering greater capacity, stability and workability in hostile environments. Allseas has released the first video in a series that will show the journey from the inception of this new system to the installation onboard the Pioneering Spirit.

Since the upending of the beams, the vessel has already completed the first commercial lift with the recently installed new JLS technology. The jacket lift system was deployed to remove the CNR International’s Ninian Northern jacket from the northern North Sea.

Weighing in at 8100 tonnes, the first commercial lift with the new JLS technology is one of the heaviest offshore jacket lifts ever, but remains well within the system’s 20,000-tonne single-lift capacity. Video of the testing and the first commercial lift will follow in the last video of the series.
