SSCV Sleipnir is a new-generation semi-submersible crane vessel created by Sembcorp Marine and has features that is not possessed by any of the existing crane vessel. It consists of a pair of revolving cranes which is capable in lifting 20,000 tonnes in tandem. The vessel is also the first dual-fuel crane vessel. Its engines runs on MGO and LNG for sustainable operations.
The world’s biggest semi-submersible crane vessel (SSCV) is set to blaze a trail when it enters into service in the coming months. Its specialities includes armed with the strongest pair of revolving cranes for offshore oil, gas and renewable energy installation and decommissioning jobs.
Sleipnir can accommodate 400 persons and will be availed globally for installing and removing jackets, topsides, deep-water foundations, moorings and other offshore structure.
Sleipnir will minimise offshore assembly work and will probably raise operational efficiency to a new level, without compromising the flexibility and robustness of traditional installation methodologies. This will be achieved due to its single-lift capability catering to larger integrated structures than previously possible.
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.
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.
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 129-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.
Mr Wong said: “In a safe environment, we can bring our best-quality work into building a reliable vessel, and this in turn helps ensure the safety of the future officers and crew aboard. Our safety mind set therefore goes beyond the successful completion of a project. It effectively complements our continuous focus on innovation and technology development, enabling us to deliver world-class products to Heerema and all other customers.
“Sembcorp Marine is grateful to Heerema Marine Contractors for giving us the opportunity to build the world’s biggest, strongest and first dual-fuel semi-submersible crane vessel at our flagship Tuas Boulevard Yard.”
SSCV Sleipnir was named by lady sponsor Mrs Maha Hatfield. The vessel is expected to depart for sea trials shortly and is scheduled for delivery to Heerema soon afterwards.
