Heerema Marine Contractor’s new semi-submersible crane vessel (SSCV), the world’s largest and most powerful in its kind, has been completed. The vessel is named Sleipnir, after the Norse God Odin’s eight-legged stallion. The christening of the vessel took place at Sembcorp Marine’s Tuas Boulevard Yard in Singapore where the vessel was built.
Sleipnir is a new-generation semi-submersible crane vessel with a pair of 10,000-tonne revolving cranes that are capable of lifting 20,000 tonnes in tandem. The cranes have a 175-metre lifting height capability. The engines are running on MGO and LNG. It has a 220-metre by 102-metre reinforced deck area and can accommodate up to 400 persons.
Several firsts
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.”
SSCV Sleipnir will be used for installation and decommissioning activities in the offshore oil, gas and renewable energy markets. 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.
The vessel will undergo sea trials shortly and will be delivered to Heerema soon afterwards.
