SINGAPORE – Sembcorp Marine has completed the semisubmersible crane vessel Sleipnir for Heerema Marine Contractors (HMC).
Named after the Norse God Odin’s eight-legged stallion, the vessel was recently christened by Maha Hatfield at Sembcorp Marine’s Tuas Boulevard Yard in Singapore.
The SSCV Sleipnir has a 220-m (722-ft) by 102-m (335-ft) reinforced deck area, making it the largest crane vessel to be built, according to Sembcorp Marine. It also has two 10,000-metric ton revolving cranes which can lift loads of up to 20,000 metric tons in tandem. The cranes are capable of a 129-m (423-ft) lifting height.
It is also 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, the Sleipnir will operate sustainably across all environmental jurisdictions.
The vessel can accommodate 400 persons and will be deployed globally for installing and removing jackets, topsides, deepwater foundations, moorings, wind turbines, and other offshore structures.
HMC has 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; and transportation and installation of the Hollandse Kust Zuid Alpha HVAC platform offshore the Netherlands.
At its peak, the construction of the Sleipnir involved up to 3,700 workers in a single shift. The project has a current Lost Time Injury Rate of 0.35 per million-man hours worked, according to Sembcorp Marine.
The vessel will leave for sea trials shortly and is scheduled for delivery to Heerema soon afterward.
