Contract for shrimp stern trawler

The vessel will be designed and equipped by Rolls-Royce. With a length of about 80m, the ICE 1A* ice-classed trawler of Rolls-Royce NVC 374 design will be equipped with several Rolls-Royce systems, including a B33:45 main engine, Promas propulsion and a power electric system with hybrid shaft generator (HSG). The package also includes a tunnel thruster, automation, and winches. The contract is worth in excess of GBP 6 million to Rolls-Royce
The trawler will be equipped with fishing winches driven by permanent magnet (PM) engines. The PM winch engine is particularly suited to applications that operate in harsh conditions and combine a need for sensitive control and rapid changes in pull and speed, Rolls-Royce said.
Operational efficiency in ice, low emissions, crew comfort, safety and excellent seakeeping capabilities have been the main considerations in the development of the ship design and complete equipment package, it added.
The vessel’s main engine is a medium-speed Bergen B33:45, offering a 20% increase in power per cylinder compared with existing engines in the Bergen range. The engine has a specific fuel consumption of 177g/kWh at full load and complies with IMO Tier II and III rules. It is designed to run for 25,000 hours between major maintenance when operating at average loads.
The Rolls-Royce hybrid shaft generator (HSG) is an advanced electric power control system for conditioning the electrical power coming from a shaft generator. It allows shaft speed to be reduced while maintaining a constant frequency for the electrical supply throughout the ship. This permits a much more flexible use of engine and propeller speed variations to maximise both propeller and engine efficiencies by running them at their design points, according to Rolls-Royce.
The vessel encompasses an onboard factory for the production of a variety of shrimps, and has a storage capacity of 2,100m3 on specialised decks for palletised cargo. There are also two packaging holds on two decks.
The vessel is to be delivered from VARD’s Aukra yard in Norway in December 2016.
