Named after Norse God Odin’s eight-legged stallion, Sleipnir features a 220-metre by 102-metre reinforced deck area and has the capacity to lift 20,000 tonnes in tandem through two 10,000-tonne revolving cranes.

The vessel also holds the distinction 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.

Sleipnir can accommodate 400 individuals and will be deployed around the world to install and remove jackets, topsides, deep-water foundations, moorings and other offshore structures. Heerema has already secured contracts to deploy Sleipnir for 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.

The vessel will leave for sea trials and is scheduled for delivery to Heerema soon.
