Feature 5 |FISHING Sophisticated vessel a major delivery
Macduff Shipyards Ltd has recently completed its most prestigious order to date, with the handing over of the vessel Alba Na Mara.
Fisheries Research Services, an agency of the Scottish Executive, to replace Clupea, and the new ship will be based in Fraserburgh. Te contract was awarded on a ‘design and build’ basis and is a one-off design specially developed for this project. The vessel was built entirely at
A
Macduff, with the steel kit being produced by the yard’s prof iling division. Te project was also managed by Macduff Ship Design Ltd. Te new vessel will carry out inshore
research, surveys, and monitoring work to underpin advice given to government in relation to Scotland’s fisheries and aquacultive sectors. It is equipped with a sophisticated range of deck machinery and electronics to allow a wide range of fishing and environmental sampling operations to be carried out, and will carry 15 personnel for up to 14 days. Alba Na Mara has been designed as
a research vessel suitable for fisheries research, single, twin, pelagic/demersal/ trawl ing and scal lop dredging, hydrographic sampling, surveying, and camera work. The area of operation covers the whole of the British Isles. The vessel has been cerified by
the United Kingdom Maritime and Coastguard Agency (MCA); the Small Commercial Vessel and Pilot Boat Code of Practice (MGN 280) Category 1 - up to 150miles from a safehaven; the Certifying Author- ity Society of Consulting Marine Engineers and Ships Surveyors; and the

Alba Na Mara was built by Macduff Shipyards for the Fisheries Research Services of Scotland.
Certification of Hull Sea Fish Industry Authority. The vessel will be operated in all
seasons, and to facilitate scientific operation the sea-keeping proper- ties and stability have been optimised to provide a safe working platform in conditions up to Beaufort Force 6, and sea state 5-6. With a length overall of 27m, a length
bp of 23.55m, a moulded depth of 8.80m, and a depth of 4.30m, Alba Na Mara has been designed with a round bilge hull form, with bulbous bow, transom stern, and ballast keel. Extensive studies were taken on hull form and the shape of the bilge keels before construction started, in conjunction with CTO Poland. Te hull and three quarter length upper deck are constructed in steel, and the wheelhouse constructed in marine grade aluminium alloy. In view of the nature of the work to be
undertaken, extensive studies were also made in reducing noise and vibration in the vessel, under the direction of
Van Cappellen Consultancy, from Te Netherlands. The vessel has twin screw propul-
sion with two Mitsubishi S6R MPTKF engines, each rated at 630hp at 1600rev/ min, driving through Reintjes WAF364L gearboxes with 4.92:1 reduction ratio to 1800mm diameter five-bladed open Promarain propellers. Te engines were flexibly mounted, with the gearboxes free standing. Te Mitsubishi engines were supplied by Macduff Diesels Ltd. Te main generators, situated in the
engineroom, were Scania, each with an output of 220kW 415/3/50 and the sets were produced by Beta Marine. In addition, a Mitsubishi 6D16T harbour set with 97kW 415/3/50 output was fitted in the aſt machinery space. As is expected on a vessel of this type,
there is a great deal of deck equipment, including: three split trawl winches; a net drum; a double anchor windlass; a hydrographic winch; a Triplex cargo handling crane of 18.0tonnes/m; and a trawl computer system. SBI
