Two new 78m purser/trawler fishing vessels being designed and built at Karstensen Shipyard in Denmark will feature Wärtsilä’s main propulsion and control equipment.

The ships have been contracted by Lunar Fishing, the Scotland based fishing company and will operate in the North Sea.

For each vessel, Wärtsilä will supply a 9 cylinder in-line Wärtsilä 32 engine, a 2-speed gear with power take-off function (PTO), a Wärtsilä Controllable Pitch propeller 4E1095 complete with shaft line, seals and bearings, stern tube, High Performance nozzle (HP-Nozzle) and the new Wärtsilä Protouch propulsion control system.

The equipment for the first vessel will be delivered at the end of 2015, and for the second vessel in summer 2016.

Wärtsilä says that the selected propulsion package features a number of benefits that were key considerations in the award of the contract. The combination of the well proven Wärtsilä 32 engine, which combines output power of 580 kW per cylinder with excellent fuel efficiency, with the company’s new 2-speed gear solution offers both operating cost (OPEX) savings and high overall propulsion efficiency.

The Wärtsilä 2-speed gear offers both economic and environmental benefits, particularly for fishing boats and other vessels having multiple operational modes or reduced transit speed. The SCV 112/2 gear selected for these vessels is currently the largest in Wärtsilä’s 2-speed gear portfolio. It features two gear ratio settings, which facilitates a reduced propeller speed at an optimal and constant engine speed. This allows the electric power generation for the PTO on the gear to remain uninterrupted in both trawling and transit modes, while maintaining high propeller efficiency at all times. Furthermore, the hydro-acoustic noise is reduced when operating at low propeller rpm, which improves the vessel’s fishing capabilities.

“These vessels will represent the state-of-art for fishing applications. The excellent fuel efficiency and operational flexibility that is made possible by the integrated Wärtsilä propulsion system will produce fuel cost savings and greater operating efficiency,” confirms Alex Buchan, Skipper & Vessel Owner, Lunar Fishing.
