SSCV Hermod is a semi-submersible crane vessel operated by Heerema Marine Contractors.



Semi submersible crane vessel (SSCV) Hermod was constructed in 1979 by Mitsui Engineering & Shipbuilding Co., Ltd.. Hermod and sister vessel, Balder were the world's first semi-submersible crane vessels.[3] In the early 1980s these vessels set several lift records while operating in the North Sea.[4]


The hull consists of two floaters with three columns each. The transit draught of 12 meters is normally ballasted down to 25 meters for lifting operations, with the floaters (with a draught of 12 meters) are well-submerged, reducing the effect of waves and swell.

Propulsion is by two controllable pitch propellers and two forward, retractable, controllable pitch thruster. The helicopter deck will sustain a Sikorsky 61-N. Up to 336 people can be supported in the air conditioned living quarters.


The Hermod has two cranes at the stern. Originally the starboard-side crane was rated at 3000 short ton and the port-side at 2000 short ton.[4] In 1984, the lifting capacities were upgraded to 5000 and 4000 short ton respectively.[1] The main hoist can lift 92 m (302 ft) above the work deck. The auxiliary hoists can lower to a depth of 3,000 m (10,000 ft) below the work deck. A tandem lift using the main hoists can lift 9,000 short ton at 39 m (128 ft) radius.
