Wärtsilä will also supply a controlled pitch propeller (CPP) and a two-speed gearbox for the trawler, a replacement for Lunar’s existing Lunar Bow.

Alex Buchan, vessel owner at Lunar, based in Scotland, said: “So many vessels in our fleet are fitted with Wärtsilä engines and other products that we really had no hesitation in opting for Wärtsilä again. This will be the first, however, with the Wärtsilä 31 main engine and we are excited at the operational benefits it offers."

Fuel efficiency

The engine is built for fuel efficiency to minimise exhaust emissions and help meet the industry's need for lower operational costs and better environmental performance.

The two gear ratio settings on the gearbox facilitate a reduced propeller speed at an optimal and constant engine speed, which also contributes to lower fuel consumption and reduced emissions.

At low propeller RPM the hydro-acoustic noise is also minimised.

Vessel build

The deal additionally includes Wärtsilä's ProTouch system to control the propulsion operation and ensure optimal visibility for the operator.

The vessel is currently being built at the Karstensens Skibsvaerft shipyard in Denmark. The Wärtsilä 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.

“This is the third fishing vessel with a Wärtsilä 31 main engine that we have on order at the Karstensen yard," commented Stefan Wiik, vice president of engines at Wärtsilä Marine Solutions
