“I am immensely proud that Heerema Marine Contractors is again taking things further with the introduction of our new semi-submersible crane vessel. Speaking at Sleipnir’s christening in Tuas Boulevard Yard this evening, Mr Pieter Heerema, Chairman of the Board at Heerema Marine Contractors, said: With its large cranes capable of a 135-metre lifting height and a combined 20,000-tonne lifting capacity, Sleipnir is very well placed to accommodate this trend of increasingly bigger offshore wind turbines. In the offshore wind sector, Heerema sees a significant growth in the size of wind turbines and foundations, which requires specialised equipment for their installation. Heerema has already secured contracts to deploy the vessel in various offshore energy developments, including: Leviathan topsides installation in the Mediterranean Sea Tyra jackets and topsides installation and removal in the Danish North Sea Brae B jackets and topsides removal in the UK North Sea as well as transportation and installation of the Hollandse Kust Zuid (HKZ) Alpha HVAC platform in the North Sea, off the Dutch coast. Coupled with an IMO- and US Coast Guard-approved ballast water management system, Sleipnir will operate sustainably across all environmental jurisdictions. 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). 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. Sleipnir can accommodate 400 persons and will be deployed globally for installing and removing jackets, topsides, deep-water foundations, moorings and other offshore structures. No other existing crane vessel has this capability. The vessel also has two 10,000-tonne revolving cranes which can lift loads of up to 20,000 tonnes in tandem.

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 220-metre by 102-metre reinforced deck area, making it the largest crane vessel to be built. Singapore, – The world’s biggest semi-submersible crane vessel (SSCV) is set to blaze a trail when it enters into service in the coming months, armed with the strongest pair of revolving cranes for offshore oil, gas and renewable energy installation and decommissioning jobs.
