“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 scores several firsts in the industry,” said Pieter Heerema, chairman of the board at Heerema Marine Contractors. Heerema said that it 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 Netherlands coast.įurthermore, Heerema said the semi-submersible crane vessel is well placed to handle the next generation of offshore wind energy components. It also boasts an IMO and US Coast Guard-approved ballast water management system, enabling it to work across all jurisdictions. The vessel also comes equipped with dual-fuel engines and will run on marine gasoil (MGO) and LNG. With its single-lift capability catering to larger integrated structures than previously possible, Heerema said that Sleipnir will minimise offshore assembly work and raise operational efficiencies to new levels, while not compromising the flexibility and robustness of traditional installation methodologies.
Sleipnir can accommodate 400 people and will be deployed globally for installing and removing jackets, topsides, deepwater foundations, moorings and other offshore structures.
Constructed at Sembcorp Marine's Tuas Boulevard Yard (Singapore) for owner Heerema Marine Contractors, Sleipnir has a 220 m x 102 m reinforced deck area a pair of revolving cranes can lift 20,000 tonnes in tandem, exceeding the capabilities of any other crane vessel currently on the market.
