Two stern trawlers of Rolls-Royce design are contracted to be built by Freire Shipyard in Spain. One of the trawlers has been ordered by Qajaq Trawl and the other by Polar Seafood, both Greenland-based shipowners.
The two vessels are designed for catching shrimps and 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.
In addition to ship design, the equipment package includes engines, the propulsion system, automation, winches, steering gear and a power electric system. The main engine in both vessels will be the Bergen B33:45 with nine cylinders. This highly efficient engine from Rolls-Royce is 20 per cent more powerful per cylinder compared to its predecessor. This lowers the costs through the engine’s lifecycle, and permits smaller machine rooms on board.
Promas completes the propulsion system for the two new vessels. This solution integrates the propeller, a hubcap, rudder bulb and the rudder itself into a single hydrodynamic efficient unit. A Hybrid Shaft Generator (HSG) will also be installed. HSG is an advanced power electric system that enables a much more flexible use of engine and propeller speed variations to maximise both propeller and engine efficiencies, which again helps to reduce exhaust CO2 and NOx emissions.
