Pioneering Spirit is a single-lift heavy construction vessel owned by Swiss offshore contractor Allseas. At its deepest operational draught of 27 metres, the vessel displaces approximately 900,000 tonnes of seawater, making it the heaviest object ever set afloat at sea. At 403,342 gross tonnes, it is also the largest vessel ever constructed by gross tonnage.
Pioneering Spirit is 382 metres long and 124 metres wide. It is powered by eight diesel generators producing a combined 95 MW, driving 12 azimuth thrusters that give it a top speed of 14 knots and DP3-class dynamic positioning capability. Accommodation is provided for up to 571 personnel.
