Father and sons George and Michael Tait of Fraserburgh and Alex and Zander West from Gardenstown, partners in the Fraserburgh-based fishing company Mewstead LLP, signed a contract last month with Nauta Shipyard in Poland to build an 86.80m turn-key pelagic vessel for delivery in October 2017, reports David Linkie.

Particular focus has been set on optimising working, safety and comfort for the crew, optimising catch handling and storage facilities, and the optimisation of fuel consumption.

Featuring an extensive boat deck, including a futuristic stem cap, the vessel will be built to a new design concept developed by Wärtsilä Ship Design, and will feature a broad range of Wärtsilä propulsion machinery. On completion, the new build will be one of the most efficient vessels of its type in the world.

The decision to choose the Wärtsilä 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 two-speed gearbox.

Partner and skipper Michael Tait said: “This will be an extremely modern fishing vessel, so 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,”

Aaron Bresnahan, Vice President, Sales, Wärtsilä Marine Solutions added: “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.”

Although primarily intended for use as a midwater trawler, the new Fraserburgh pelagic vessel will also be semi-rigged for purse-seining, with a net bin located on the starboard quarter.

Designed for pumping pelagic fish aboard both at the stern and amidships on the starboard side, the 86.8m LOA vessel will have main dimensions of length between pp 76m, breadth moulded 17.6m and a depth to first deck of 10.4m.

The fully-integrated Wärtsilä engine and propulsion package will include a 12-cylinder Wärtsilä V32 main engine (6960kW @750rpm), two 8-cylinder Wärtsilä 8L20 auxiliary engines (1360kW @ 1800rpm), Wärtsilä 2-speed gearbox, 2500kW shaft generator, 4400mm-diameter controllable pitch propeller running in a Wärtsilä HP nozzle, a complete stern tube, including Wärtsilä Sternguard seals and Wärtsilä Sternsafe bearings. Operating through a Wärtsilä Protouch propulsion control system, the centreline machinery package was selected to ensure optimised bollard pull for trawling, as well as good free-sailing characteristics of up to 17 knots.

Electrically-driven 1200kW bow and stern thrusters will also be fitted.

In order to deliver maximum levels of catch quality, mackerel and herring will be stored in 13 RSW tanks with a combined capacity of 3,200m³, in optimum conditions provided by three high-performance refrigeration plants. Pelagic fish will be discharged using a C-Flow vacuum plant consisting of 2 x 4,200-litre tanks served by 4 x 66kW compressors.

Fuel and freshwater capacity will be 600m³ and 130m³ respectively.

The extensive accommodation area will include 16 single-berth en-suite cabins.

Karmøy Winch AS deck machinery

The new Fraserburgh vessel will feature an expensive package of customised deck machinery manufactured by Karmøy Winch AS.

This will include 2 x 96t winches, 3 x 110t net drums, top line winch (80t), midline winch (80t) 2 x tail-end winches (55t), 4 x mooring winches (11t), 2 back-strop winches (3.6t), 2 x net sounder winches, (4t) anchor winch and two fish pumps, fish hose and hydraulic pipe reels.

Two of the net drums will be positioned towards the vessel’s centreline, forward of the purse net bin, with the third on the port side, in line with twin trawl openings across the transom.

The forward mooring and anchor winches will be located on the boat deck under the bow cap, which will incorporate hydraulically-operated opening doors which the mooring ropes will be passed through when entering and leaving harbour.

Four deck cranes with an operational radius of up to 18m (5t) will also be fitted.
