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

History

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]

Design

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.

Cranes

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.
