SSCV Hermod was a semi-submersible crane vessel operated by Heerema Marine Contractors.
History[edit]
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]

Hermod was retired at the end of 2017. She was loaded on Dockwise Vanguard and taken to Dinghai District, Zhejiang province for scrapping at Zhoushan Changhong International Ship Recycling. 98% of the ship's materials will be reused.[5][6]
Design[edit]
The hull consisted of two floaters with three columns each. The transit draught of 12 meters was normally ballasted down to 25 meters for lifting operations; at that load, the floaters (with a draught of 12 meters) were well-submerged, reducing the effect of waves and swell.
Propulsion was by two controllable pitch propellers and two forward, retractable, controllable pitch thrusters. The helicopter deck was capable of sustaining a Sikorsky 61-N. Up to 336 people could be supported in the air conditioned living quarters.
Cranes[edit]
The Hermod had two cranes at the stern. Originally the starboard-side crane was rated at 3,000 short tons (2,700 t) and the port-side at 2,000 short tons (1,800 t).[4] In 1984, the lifting capacities were upgraded to 5,000 and 4,000 short tons (4,500 and 3,600 t) respectively.[2] The main hoist could lift 92 m (302 ft) above the work deck. The auxiliary hoists could lower to a depth of 3,000 metres (9,800 ft) below the work deck. A tandem lift using the main hoists could lift 9,000 short tons (8,200 t) at a 39 m (128 ft) radius.
