Rolls-Royce design and equipment for Greenland pair

Two Rolls-Royce-designed stern trawlers have contracted to be built by the Freire Shipyard in Spain for Greenland companies Qajaq Trawl and the other by Polar Seafood.



‘Rolls-Royce has a long history working with both Qajaq Trawl and Polar Seafood in designing several fishing vessels for use in a harsh climate. We are of course very happy to continue this co-operation,’ said Monrad Hide, Rolls-Royce, VP Sales – Marine.



The two trawlers are to be built to Rolls-Royce’s NVC 375 design to target shrimp and are to be equipped with a wide range of Rolls-Royce equipment. Operational efficiency, low emissions, crew comfort, safety and excellent seakeeping capabilities have been the main considerations in the development of the ship design and equipment package.



As well as the design of the two 80 metre trawlers, the equipment package includes engines, propulsion system, automation, winches, steering gear and a power electric system. The main engine in each trawler will be a nine-cylinder Bergen B33:45, a highly efficient Rolls-Royce engine delivering 20% more power per cylinder compared to its predecessor. This reduces costs through the engine’s lifecycle, and allows for smaller engine spaces on board.



Promas completes the propulsion system for the two new vessels. This integrates the propeller, a hubcap, rudder bulb and the rudder itself into a single hydrodynamic efficient unit. A Hybrid Shaft Generator (HSG) is also part of the package, providing an advanced power system that enables a much more flexible use of engine and propeller speed variations to maximise both propeller and engine efficiencies, which contributes to the reduction of CO2 and NOx emissions.



The owners of both vessels have opted for low pressure hydraulic winch systems with electrically driven auxiliary winches. In bad weather the dynamic winches keep the trawl gear in the best position to fish efficiently and reduce wear on the equipment.



The two trawlers are scheduled to be delivered in 2018/19.



Since the early 1970s Rolls-Royce has designed about 150 vessels of NVC design for the fishing industry. The current Rolls-Royce orderbook in this market now comprises seven fishing vessels and two live fish carriers.
