SSCV Hermod was 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.[1] In the early 1980s these vessels set several lift records while operating in the North Sea.[2]
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.[3][4]
Design
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
The Hermod had two cranes at the stern. Originally the starboard-side crane was rated at Шаблон:Convert and the port-side at Шаблон:Convert.[2] In 1984, the lifting capacities were upgraded to Шаблон:Convert respectively.[5] The main hoist could lift Шаблон:Convert above the work deck. The auxiliary hoists could lower to a depth of Шаблон:Convert below the work deck. A tandem lift using the main hoists could lift Шаблон:Convert at a Шаблон:Convert radius.
