The world’s biggest semi-submersible crane vessel (SSCV) is to enter service in the coming months, with the strongest pair of revolving cranes for offshore oil, gas and renewable energy installation and decommissioning jobs.
Named after the Norse God Odin’s eight-legged stallion and newly completed at Sembcorp Marine’s Tuas Boulevard Yard for owner Heerema Marine Contractors, SSCV Sleipnir has a 220m by 102m reinforced deck area, making it the largest crane vessel to be built.
The vessel also has two 10,000-tonne revolving cranes which can lift loads of up to 20,000 tonnes in tandem. No other existing crane vessel has this capability.
Sleipnir can accommodate 400 persons and will be deployed globally for installing and removing jackets, topsides, deep-water foundations, moorings and other offshore structures.
Importantly, with its single-lift capability catering to larger integrated structures than previously possible, Sleipnir will minimise offshore assembly work and raise operational efficiency to a new level, while not compromising the flexibility and robustness of traditional installation methodologies.
The vessel further stands out as the world’s first crane vessel with dual-fuel engines running on Marine Gas Oil (MGO) and Liquefied Natural Gas (LNG). Coupled with an IMO- and US Coast Guard-approved ballast water management system, Sleipnir will operate sustainably across all environmental jurisdictions.
