The Hermod is a semi -submersible crane vessel -. The Hermod is the sister ship of Balder. Both ships were built in 1978 by the the Japanese Mitsui Group company Mitsui Engineering & Shipbuilding Co.. The ship is also called SSCV Hermod. The name is derived from semi - Submersile Crane Vessel (German semi-submersible crane vessel forming ) and the Germanic god Hermodr, the brother of Balder, ago. The ship is mainly used by the Dutch company Heerema Marine Contractors as a working ship in the offshore industry.
Construction and performance
At the time of its draft Hermod and Balder revolutionized shipbuilding for work boats, as they were leading the way due to their design and performance.
The body of the Hermod was identical to the Balder: It comprises two floats which are connected to three columns to the deck structure. 1985 more ballast tanks were mounted on the hull and to the column to increase the capacity of the vessel. The draft, which is in the transfer of approximately 12 meters ( m ), is lowered during the operation to around 28 m in order to reduce the influences of waves and surface currents.
It is driven by a diesel-electric system. The electric power generated by diesel generators, each with seven 2765 kilowatts ( kW). Go with the flow the two electrically driven variable pitch are driven at the rear, each with 4400 kW and the two electrically driven and retractable jet drives, each with 1470 kW.
To anchor the ship, the twelve 22.5 -ton " Delta Flipper" Anchors are used. They are fixed to 4500 m long steel cables that have a minimum breaking strength of 386 t.
The ship has the crew and workers' accommodation for up to 336 people. Due to the environmental conditions all cabins are heated and air conditioned. A helicopter deck on the ship is also available. On his helicopter can land up to the size of a Sikorsky S-61.
With its two cranes that can lift Hermod with a projection of up to 39 m in tandem lift up to 8100 tonnes ( t). With minimum overhang both cranes are capable of 600 t to a depth of 3000 m from lowering below the working deck.
