The tallest maritime crane
The tallest maritime crane used in offshore construction is found on the semi-submersible crane vessel called SSCV Selipnir, owned and operated by Heerema Marine Contractors.
The vessel was constructed by Sembcorp Marine in Singapore and entered service in 2019.
The vessel is 220 m long and 102 m wide, with a displacement of 273,700 tonnes and a draft between 12 and 32 m.
It can accommodate 400 crew members and was designed for the installation and removal of jackets, topsides, deepwater foundations, modules, moorings, and other offshore structures.
It minimises offshore assembly processes by allowing for single-lift installation of massive integrated structures.
It has 8 Wartsila azimuth thrusters and 12 dual-fuel engines, which can run on either marine gas oil or LNG, making it the first dual-fuel crane vessel in the world.
The vessel has two main cranes that reach as high as 220 m or 722 feet, making them the tallest offshore cranes, surpassing the height of several iconic buildings.
