Karstensens Skibsværft has designed and delivered the versatile new pelagic trawler Gollenes for its Fosnavåg-based owners. This is a repeat order by the owners of Gollenes AS, who have recently sold their 62-metre previous vessel, which was delivered by the same yard in 2011.
Fishing company Gollenes AS is owned by the the Ose and Kvalsvik families in Fosnavåg, and headed by skipper Frode Kvalsvik. The upcoming generation of both families is also on board, represented by Ivar Ose Bjørneset and Willy Kvalsvik.
They went to Karstensen a couple of years ago with their ideas for a versatile new trawler capable of fishing for heerring and mackerel, as well as having capacity for some industrial fishing and whitefish. The resulting design takes all of these requirements into account.
The resulting 69.99 metre LOA, 14.80 metre breadth design – newbuild #468 for the yard – has a 1970 cubic metre capacity in its RSW tanks, chilled by a double 1300kW FrioNordica system and served by a C-Flow vacuum pump system with two tanks and four 90kW compressors. The owners wanted a fully watertight cargo deck, and there’s also a processing deck and a silage installation to ensure full utilisation of raw material.
The deck layout has SeaQuest deck cranes and an all-electric MacGregor package of three trawl winches, four net drums and two fish pumps, with capacity to pump catches on board over either quarter.
Gollenes has a very green profile, with a strong emphasis throughout the design process of minimising energy consumption, with LED lighting and other measures, as well as energy recirculation.
The propulsion configuration is imaginativem, with a medium-speed ABC 6DL36 main engine delivering 3995kW, along with three Scania DI16 gensets each capable of generating 615kWe, plus there’s a 2000kW Marelli shaft generator.
The owners of Gollenes went to Brunvoll Volda for the hybrid propulsion system with a slow-running 4500mm controllable pitch propeller via the ACG 980 gearbox with a 6.82:1 reduction.
This is a diesel-mechanical/hybrid propulsion system with PTO/PTI. This setup provides options for mechanical and electric modes of operation as while the main engine runs the propeller via the gearbox, the PTI allows for a boost mode, while also serving as a take-me-home option by routing power to the shaft from the auxiliary engines.
The Brunvoll package also includes a thruster system with a pair of 950kW transverse thrusters and BruCon control system.
