The Sleipnir is designed for worldwide offshore heavy lifting. It is equipped with two cranes of 10,000 metric tonnes lifting capacity each and a reinforced deck area of 220 meters in length and 102 meters in width, which make it the largest crane vessel in the world. The dual cranes provide for heavy lifting capacity both to install and remove jackets and topsides. Furthermore, the cranes can be utilized for installation of foundations, moorings and structures in deep water. The Sleipnir is self-propelled with a minimum service speed of 10 knots, with power generated by means of dual fuel engines – MGO & LNG. Station-keeping is by means of dynamic positioning (DP3) or mooring system.
