Macduff Ship Design is delighted to announce the recent handover of two fishing vessels completed by Macduff Shipyards

Macduff Ship Design is delighted to announce the recent handover of two fishing vessels completed by Macduff Shipyards Limited, the ‘Faithful FR 129’ and the ‘Crystal River FR 178’ to their respective owners Stewart Buchan and David Cardno of Fraserburgh.

These vessels operate exclusively as a pair trawl team fishing out of their home port Fraserburgh and have the distinction of being the yards first new-build pair trawl order in over thirty years, the previous vessels being the wooden-hulled ‘Solitaire’ and ‘Sonia Jane’ built in the ’80s.

To deliver the vessels at the same time the production was split between the yard’s facilities with the Faithful being built in the Macduff main fabrication hall and the Crystal River being built in the Buckie fabrication hall. To assist with the build schedule, many of the steel units for the Crystal River were also built in Macduff before being shipped by sea to Buckie for assembly.

The Faithful and Crystal River have been built to an identical design and share the same hull form as the Good Hope FR 891, also built by the yard in 2019. The hulls measure 26.50 m length overall with a registered length of 23.95 m, 7.80 m breadth and 4.20 m moulded depth. This hull form was developed using CFD technology, assisted by the Wolfson Unit in Southampton, to interrogate and optimise their design to reduce resistance and fuel consumption whilst also allowing for the large volume fish holds which can carry 1,150 fish boxes per vessel.

Macduff Ship Design played a crucial role in developing the hull model, fairing its lines, analysing the stability, draughting a full set of structural plans and producing a computer ‘kit’ of steel parts required to build the hull.A bespoke hydraulic deck machinery package was fabricated by the yard for the vessels comprising of a large triple barrel winch powered by a Hagglunds CA210, two split net drums, one bagging net drum, one small gear handling winch, cod-end lifting winch and a dedicated anchor windlass.

Thistle Marine of Peterhead supplied both the MFB8 landing crane and MBK13 power block crane, both of which featuring a slew ring base.  Primary hydraulic power is provided by a single Denison hydraulic pump driven from a dedicated Cummins QSL9-M auxiliary engine producing 330 hp whilst secondary hydraulic power is provided by a separate Denison hydraulic pump driven from a power take-off fitted to the main propulsion’s gearbox. A hydraulically powered bow thruster is also fitted at 280 hp. The hydraulic system, designed by the yard, is cooled via a Blokland box cooler and Bowman heat exchanger.

The propulsion package features a 2.5 m fixed pitch propeller supplied by Wartsila, driven by a CATERPILLAR C32 main engine with 750 hp @ 1600-1800 rpm through a Masson Marine W7400 reversible gearbox with 9.077:1 reduction. The efficiency gains predicted during the early design phase were realised during engine trials with the vessel achieving 9.0 knots at only 50% engine load and 10.7 knots at 100% load. Both vessels also feature a triple rudder system along with a modern high lift propeller nozzle provided by Wartsila. 

Cooling systems for all engines and hydraulics onboard are served by box coolers supplied by Blokland Non-Ferro. Electrical power onboard is provided by two Mitsubishi generator sets supplied by Macduff Diesels Limited, each with a rating of 98 ekW and sufficient size to run the vessel’s power independently providing complete redundancy.

The electrical systems onboard were designed and fitted by R.D. Downie who also fabricated the vessels switchboard and control panels for all the pumps and motor starters. In addition to this R.D. Downie also provided the fire, bilge and gas alarm systems on board along with the navigation light panel and assisted with the installation of the navigation equipment.

The fish processing decks features a tailor-made catch handling system built by the yard from the owner’s design. Two separate compartments are formed within the fish processing area which both contain a 2.5 t Geneglace ice machine and associated plant. The fish hold refrigeration system along with ice machines were supplied and fitted by Premier Refrigeration.

The high specification navigation package was supplied and fitted onboard by Woodsons of Aberdeen, please contact Steven Wood for full details. Trawl monitor sensors were supplied and installed by Scanmar Ltd, please contact George Youngson for details.
