Sembcorp Marine of Singapore Launched the World’s Largest Semi-Submersible Crane Vessel – The Sleipnir.

The Sleipnir, named after the eight-legged horse of the Norwegian god Odin, is being built for the Dutch offshore service company Heerema Marine Contractors. With a reinforced deck area of 220 meters by 102 meters, the Sleipnir is the largest vessel of its kind ever built. The Sleipnir, which will enter service in the coming months, is equipped with two 10,000-ton rotating cranes that can lift loads of up to 20,000 tons in tandem.

The Sleipnir will serve for offshore installation and decommissioning work for oil, gas, and renewable energy.

It can accommodate 400 people and will be deployed globally for the installation and removal of jackets, topsides, deep-water foundations, moorings, and other offshore structures.

Heerema Marine Contractors has already secured contracts to deploy the SSCV on several offshore projects, including the installation of topsides for the Leviathan in the Mediterranean Sea; Tyra jackets and topside installation and removal in the North Sea of Denmark; Brae B jackets and topside removal in the North Sea of the UK; as well as the transportation and installation of the Alpha HVAC platform of Hollandse Kust Zuid (HKZ) in the North Sea, off the Dutch coast.

“In the offshore wind sector, Heerema sees significant growth in the size of wind turbines and foundations, which require specialized equipment for their installation. With its large cranes capable of reaching heights of 175 meters and a combined lifting capacity of 20,000 tons, the Sleipnir is well-positioned to accommodate this trend of increasingly larger offshore wind turbines,” said the Dutch company.

During the christening of the Sleipnir at Tuas Boulevard Yard on Friday in Singapore, Pieter Heerema, Chairman of the Board of Heerema Marine Contractors, said: “I am immensely proud that Heerema Marine Contractors is once again pushing things forward with the introduction of our new semi-submersible crane vessel. The Sleipnir marks several firsts in the industry: it is the largest crane vessel ever built; it has the strongest pair of rotating cranes; and it is also the world’s first crane vessel with dual-fuel engines operating on MGO and LNG, significantly reducing harmful emissions. The innovative capabilities of the Sleipnir will position Heerema even more firmly at the forefront of developments in the offshore oil, gas, and wind energy industries for installation and decommissioning.”

The vessel will head out for sea trials soon and is scheduled to be delivered to Heerema shortly thereafter, Sembcorp Marine said.
