Wärtsilä was contracted by the Scottish based company LunarFishery to supply fully integrated propulsion solution for an new trawler. The vessel is being built at the Karstensens Skibsvaerft shipyard in Denmark.
The new ship will replace the purse seiner trawler »Lunar Bow« and w[ds_preview]ill have the same name. The main engine chosen is the Wärtsilä 31. According to the manufacturer it is listed by Guinness World Records as being the world‘s most efficient 4-stroke diesel engine. Its outstanding fuel efficiency results in the corresponding benefit of producing fewer exhaust emissions, thereby meeting the industry‘s need for lower operational costs and better environmental performance.
Wärtsilä will also supply a controlled pitch propeller (CPP) and a 2-speed gearbox. The two gear ratio settings facilitate a reduced propeller speed at an optimal and constant engine speed, which also contributes to achieving lower fuel consumption and reduced emission levels. Furthermore, at low propeller rpm the hydro-acoustic noise is minimised; an important consideration for the vessel‘s fishing capabilities.
Controlling the entire propulsion operation will be Wärtsilä‘s ProTouch system, a comprehensive arrangement of levers, touch-screen interfaces, displays, indicators, and modules that ensures optimal visibility for the operator. This promotes added safety, both at sea and in port.
The equipment is scheduled to be delivered to the yard in early 2019 and the vessel is expected to begin fishing operations in the North Sea later that year.
