Worlds most efficient Pelagic Trawler to feature Wärtsilä design and propulsion machinery

A new pelagic fishing trawler ordered by Scottish owner Mewstead LLP will be built according to a Wärtsilä design and will feature a broad scope of Wärtsilä propulsion machinery. The ship is to be built at the Nauta Shipyard in Poland and when completed will be the largest and most efficient ship of its type in the world. The contract with Wärtsilä was signed in November. Delivery of the vessel is scheduled for mid-2017.

The decision to choose the Wärtsilä ship design was based on the high level of efficiency derived from the optimised hull lines. This optimisation, together with Wärtsilä’s highly efficient integrated engine and propulsion solution, results in far lower fuel consumption than would otherwise be possible. Other decisive factors in the award of this contract were the vessel’s bollard pull capability and improved working conditions for the crew, such as the reduced noise levels made possible by Wärtsilä’s 2-speed gearbox.

“Wärtsilä Ship Design has a reference list of more than 200 fishing vessels built, making us one of the world’s leading designers in this field. At the same time, we have the industry’s most comprehensive portfolio of products, systems and solutions, thus enabling us to optimise the design and the propulsion so as to achieve the greatest efficiency and lowest operating costs, as we have in this case,” says Aaron Bresnahan, Vice President, Sales, Wärtsilä Marine Solutions.

“This will be a very large and extremely modern fishing vessel and it is important that the design and the equipment driving the vessel also feature the very latest and best technologies. We are confident that the Wärtsilä design and equipment solutions fully meet our needs,” says M Michael Tait, owner of the vessel.

The full Wärtsilä scope of supply includes the ship design, a 12-cylinder Wärtsilä 32 main engine, two 8-cylinder Wärtsilä 20 auxiliary engines, a 2-speed gearbox, a controllable pitch propeller (CPP) running in a Wärtsilä HP nozzle, a complete stern tube including Wärtsilä Sternguard seals and Wärtsilä Sternsafe bearings. Wärtsilä will also supply its Protouch propulsion control system.

The vessel will operate in the North Sea in the fishing grounds around the coast of Scotland.
