The world’s biggest semi-submersible crane vessel (SSCV) is set to enter into service in the coming months for Heerema Marine Contractors, for offshore oil, gas and renewable energy installation and decommissioning jobs. This is also the world’s first dual-fuel crane vessel.
Named after the Norse God Odin’s eight-legged stallion and newly completed at Sembcorp Marine’s Tuas Boulevard Yard, SSCV Sleipnir has a 220-metre by 102-metre 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, a world’s first 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 MGO and LNG, coupled with an IMO- and USCG-approved BWMS, to comply with all environmental jurisdictions.
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,
…said Mr Pieter Heerema, Chairman of the Board at Heerema Marine Contractors, speaking at Sleipnir’s christening in Tuas Boulevard Yard.
At its peak, the construction of Sleipnir involved up to 3,700 workers in a single shift. The project has a current Lost Time Injury Rate (LTIR) of 0.35 per million man hours worked, a commendable safety performance which Sembcorp Marine President & CEO Mr Wong Weng Sun said reflects the Group’s strong safety commitment.
Sleipnir is also well placed to accommodate the trend of increasingly bigger offshore wind turbines.
The vessel will leave for sea trials shortly and is scheduled for delivery to Heerema soon afterwards.
