Hereema's Mega Crane Vessel Finished Construction

Sembcorp Marine has finished construction of the SSCV Sleipnir for owner Heerema Marine Contractors. The world’s biggest semi-submersible crane vessel (SSCV) has a 220-metre by 102-metre reinforced deck area, making it the largest crane vessel to be built. It is armed with the strongest pair of revolving cranes for offshore oil, gas and renewable energy installation and decommissioning jobs. 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.

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.

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. With its large cranes capable of a 175-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.

Speaking at Sleipnir’s christening in Tuas Boulevard Yard this evening, Mr Pieter Heerema, Chairman of the Board at Heerema Marine Contractors, said: "I am immensely proud that Heerema Marine Contractors is again taking things further with the introduction of our new semi-submersible crane vessel. Sleipnir scores several firsts in the industry: It is the largest crane vessel yet built; it has the strongest pair of revolving cranes; and it’s also the world’s first crane vessel with dual-fuel engines running on MGO and LNG, dramatically reducing harmful emissions. Sleipnir’s innovative capabilities will place Heerema even firmer at the forefront of developments in the offshore oil, gas and wind energy industry for both installations and decommissioning."
