The delivery of pelagic vessel Hardhaus to its Norwegian owners follows closely behind the completion of Libas earlier this year. Both have been built by the Cemre Shipyard, designed by Salt Ship Design.
Hardhaus measures 74.50 metres with a 16 metre beam and has a 2400m3 carrying capacity in its RSW tanks.
Looking for a a highly energy-efficient vessel, Hardhaus’s owners went to Salt Ship Design for ideas, and opted for a Wärtsilä propulsion system which includes a 1017kW/h battery pack, which provides opportunities for stabilising power consumption through peak shaving. It allows high load variations to be avoided, as well as enabling the main engine to run at a constant load while in transit. The battery pack serves back-up power while Hardhaus is in port, with part of the battery reserved for emergency power, so there is no harbour genset on board.
The main engine is a 4880kW 8V31 driving a 4D1095 propeller, offering both diesel-electric and diesel-mechanical operation.
The twin gensets are 750ekW units and Hardhaus has the capacity to produce an overall 6000kW output via its 3500kW PTO/1500kW PTI shaft generator, with the battery pack able to provide a power boost when required.
Hardhaus has no shortage of energy-saving systems on board, including LED lighting throughout, systems to harness excess heat and power, and an all-electric Rapp Hydema deck equipment package. This starts with a pair of 80-tonne main trawl winches, a 65-tonne net drum and end wire, tail end, net sounder and other winches. Rapp Hydema also provides the twin 37.30-tonne purse winches, while Triplex supplied the purse seine handling equipment, including a 50-tonne electric net hauler with a permanent magnet motor.
The net crane, intermediate roller, ring needle, cork line and sink line stackers, as well as an 83t/m net handling crane are all from Triplex, as are the 60t/m deck crane and fish pump cranes. The pair of 20-inch electric fish pumps are from Rapp Hydema, who also supplied the fish hose and power cable reels for both aft and forward pumping stations.
Hardhaus has a double water separator on the forward deck, routing fish to the 2400m3 capacity RSW tanks, with a double 1238kW C-Flow-Oyangen RSW system utilising R-7117 as its refrigerant and with four 750m3/hour RSW pumps. The vacuum pump system has twin 4.2m3 tanks.
Family-run fishing company Hardhaus AS goes back a long way to when the first Hardhaus was a whaling vessel built in 1954, converted in 1963 to operate as a purse seiner. The company currently operates pelagic vessels Harvest and Hardhaus.
The previous Hardhaus, built at Fitjar Mek. Verksted, has been acquired by Icelandic fishing company Ísfélagið to become Álsey VE-2, delivered to the Westman Islands as the new vessel’s delivery approached.
