Hav Line AS, Norway, has ordered the world's first processing and transportation vessel for the fish farming industry to be equipped with a hybrid propulsion solution supported by batteries.
Wärtsilä has been contracted to deliver the ship design for the new vessel to be built at the Balenciaga shipyard in Spain. The company will also supply an integrated solution comprising a 10-cylinder Wärtsilä 31 main engine, the 2-speed gearbox, the controllable pitch propeller (CPP) including the HP propeller nozzle, stern tube seals and bearings, a ProTouch propulsion remote control system, two 9-cylinder Wärtsilä 20 auxiliary engines, and the electrical and automation system including a hybrid battery PTI/PTO package.
Operating on Optimum Design Point
The hybrid propulsion solution results in very low emission levels. By absorbing most of the engine's load fluctuations and vessel load variations through batteries, the engines can be operated close to its optimum design point, thereby providing the highest level of efficiency, which in turn minimises the exhaust emissions.
The vessel's hybrid propulsion machinery has the PTI/PTO (power take-in/power take-off) powered by batteries, and is combined with the fuel efficient Wärtsilä 31 main engine. The environmentally sustainable hybrid battery configuration is new for this type of vessel.
The vessel is to be delivered in summer 2018.
