Wärtsilä has secured a contract to provide the engines and the complete propulsion package, including the propulsion control system for two new fishing trawlers. The vessels are being built for Nord Pigrim, based in Murmansk, Russia.
The 80 m long ships are to be constructed at the PJSC Vyborg shipyard in Russia. They will be reinforced to Ice3 class, thereby enabling them to extend their fishing operations in the Barents Sea and North Atlantic. Because of the challenging conditions, the reliability and efficiency of the propulsion arrangement was considered a key factor in the award of the contracts to Wärtsilä. Furthermore, the engines manufactured by the Finnish company are compliant with the IMO’s current Tier II regulations.
Wärtsilä’s full scope of supply is for each ship one 8-cylinder Wärtsilä 32 main engine, one gearbox, one controllable pitch propeller system, one transverse thrusters system, and a ProTouch propulsion control system. Auxiliary generating power will be supplied by one 6-cylinder and one 4-cylinder Wärtsilä 20 Auxpac engine. The equipment is scheduled for delivery to the yard in March 2018 and January 2019.
The gearbox has integrated hydraulics, which increases its reliability while also reducing the space needed. This arrangement facilitates easier installation and commissioning.
