​Crab Fishing Vessel ‘EUROCLYDON’ delivery

Macduff Ship Design is delighted to announce the recent completion and delivery to its owners of the MFV EUROCLYDON, GY77.

EUROCLYDON is the second crab fishing vessel built for Stuart MacDougall of fishing company Euroclydon Ltd in the space of only three years. Both vessels were designed by Macduff Ship Design and built by Macduff Shipyards Ltd.

The vessel is built to a full new design of vivier crabber fishing vessel. It features many similarities to the first vessel, MFV LEVANTER, with a similar arrangement throughout. However, with increased length, breadth, and depth, the EUROCLYDON provides noticeably more space all around to enhance crew comfort, sea keeping and fishing activity.

The design work began in the summer of 2020 with consultation between the yard and owner to finalise the general arrangement to their exact needs. With the initial design complete, the construction plans were drawn up by Macduff Ship Design and submitted to the MCA for plan approval under their newly adopted construction standard, inherited from Seafish.

The hull of EUROCLYDON up to the main deck along with the aft accommodation casing and the forward section of the shelter is built from Lloyds grade A shipbuilding plate. The mid part of the shelter where fishing activities take place, along with the wheelhouse and mast is built from marine grade aluminium to help reduce the vessels’ displacement. The hull form features a double chine hull form, transom stern and a modern bow designed to cut cleanly through the sea with less energy leading to a reduction in fuel consumption and emissions along with increased crew comfort.

The layout of the EUROCLYDON below the main deck features two three-man cabins aft, followed by a large engine room which extends forward over the top of the vivier tank. The vivier tank is positioned amidships with its trunk up to the main deck fitted through the engine room. Forward of the engine room, a bait store is situated and finally a water tank is fitted forward of the collision bulkhead in the bow.

Above the deck features the accommodation area aft with galley/mess to starboard, WC aft and a two berth skippers’ cabin and dry locker/laundry to port. Forward of this is the large fully sheltered working deck where the pots are brought onboard, catch emptied into the vivier tank, and pots stacked up until ready to shoot again. The shelter is protected by a large hydraulically powered hatch. The hauler is mounted forward and leads to a block which is fitted at the end of a telescopic boom which extends outboard of the hull to keep the pots clear of the side when hauling up. Forward at the main deck a weather-tight bulkhead is fitted, and a store space is arranged with shelving for storage and the anchor chain locker.

Above the shelter deck, a large open deck space provides for generous stowage of pots when moving gear to the grounds.

EUROCLYDON features some safety features built into the hull such as recessed foot/hand holds beneath the port and starboard fixed side ladders extending below the waterline and permanent guard rails around the wheelhouse perimeter. In addition, the owner’s preference for a raised shooting table is arranged in place of a low deck-level side opening to keep the crew safe within the shelter.

EUROCLYDON is fitted with a large vivier tank with a capacity of over 40,000 litres of seawater. The tank is subdivided with fibreglass grating partitions so the catch can be separated into different species/grades. The tank is serviced by two large electrically powered circulation pumps supplied by Bombas Azcue with the intention of one pump being used in service and one on standby. Overflow pipes are arranged port and starboard, above the waterline, so the crew and skipper can visibly see when the pumps are in operation.

The propulsion setup of EUROCLYDON is based around an innovative, large 2000 mm diameter four-bladed propeller designed and supplied by Wartsila. During the creation of the specification, the yard put forth to the owners a Mitsubishi S6B3 with 320 kW output as the proposed main engine due to its success and fuel economy on other projects in the past. Wartsila was then asked to investigate the optimal propeller diameter and design for the vessel given the engine particulars and a range of gear reductions available. Upon their conclusion, the 2m propeller was selected along with a Masson Marine W6000 gearbox with a large ratio of 8.705:1 which was calculated to provide optimal free steaming thrust per kW of power available. It was witnessed during trials that the vessel achieved a good speed for her length and the propulsion package performed smoothly with little vibration.

A hydraulic system was designed by Macduff Shipyards and features a 1.5 t hauler provided by Britannia Engineering, a telescopic boom for the hauling block and a large hauling hatch supplied by the yard, a KT120 bow thruster with 800 kg of thrust supplied by Kort Propulsion, and a MFB6 landing crane provided by Thistle Marine. Hydraulic power is provided by two large 37.5 kW motors which can be powered separately, or simultaneously, by either of the vessel’s generator sets providing complete redundancy.

22.75m FISHING VESSEL ‘CELESTIAL DAWN’ – PRESS RELEASE

Macduff Ship Design are pleased to announce the delivery of the fishing vessel ‘CELESTIAL DAWN, BF 109’, to owner George Hepburn and partners. Built by Macduff Shipyards the vessel replaces the owner’s previously vessel of the same name, which was built by the same yard in 2000.  Like the previous vessel, it is intended that she will fish out of Peterhead in the North East of Scotland, targeting primarily prawns in the North Sea.

CELESTIAL DAWN is a completely new design which was developed with close collaboration between Macduff Ship Design and Macduff Shipyards. The vessel is the first of a series which now stretches to three sisterships, with the second vessel already under construction, and the third vessel due to commence construction later in the year. This series of fishing vessels will share not only the same hull form but also the same place of origin, with all three vessels being built at the shipyard’s fabrication hall in Buckie, a significant milestone for both the yard and town.

The design of Celestial Dawn began in 2018 and although intended to fish in a similar way to the owner’s previous vessel, the design of the new vessel was focused on both enhancing crew comfort and improving fuel efficiency. During the early design phase, the Wolfson Unit in Southampton was commissioned to run a case study of two hull forms utilising CFD technology. The first hull form was a design previously built by the shipyard for a similar type of fishing, the second was a new concept model for the CELESTIAL DAWN featuring increased waterline length, a gradual bustle forward of the propeller and a new stem design where the bulbous bow was not fully submerged but rather tapered gradually into the bow’s upper region. Results from the study indicated a significant reduction in hull resistance at the two test speeds of 8 and 10 knots which were verified recently during sea trials where the CELESTIAL DAWN recorded an average top speed of 10.5 knots. Another significant difference between designs was the increase in the beam from around 7.0 m of previous vessels in this category up to around 7.6m. The increase in beam allowed the vessel to carry less internal ballast whilst also creating more deck space which was of particular benefit within the accommodation and fish processing areas. As a result of the increased dimensions, the gross tonnage of the vessel was around 10% higher than the previous CELESTIAL DAWN.

With the initial design complete the construction plans and steel cutting data were drawn up by Macduff Ship Design. The hull of CELESTIAL DAWN is built entirely from steel, with an aluminium wheelhouse and mast.  The hull features double chine construction, transom stern and a modern bow designed to cut cleanly through the sea with less energy leading to a reduction in fuel consumption and emissions along with increased crew comfort. In broad terms, the vessel’s arrangement is conventional for a Scottish trawler of this size. Below deck features the cabins, engine room, fish hold and a large freshwater tank forward of the collision bulkhead. Whereas above deck is situated the aft shelter, galley/mess and side passage area, fish processing area and then forepeak where the trawl winch is situated.

A bespoke hydraulic deck machinery package was fabricated by Macduff shipyard comprising of a triple barrel winch featuring a Hagglunds compact CA210 motor, two split net drums complete with two Hagglunds compact CA70 motor per drum, two bagging winches complete with Hagglunds CA70 motors, two small gear handling winches and a cod end lifting winch. Thistle Marine of Peterhead supplied both the MFB8 landing crane and MBK13 powerblock crane, both of which feature a slew ring base. Primary hydraulic power is provided by a single Parker hydraulic pump driven from a dedicated Mitsubishi 6D24 auxiliary engine producing 218 kW whilst secondary hydraulic power is provided by a Parker hydraulic pump driven from a power take-off fitted to the main propulsion’s gearbox. A hydraulically powered bow thruster with 1.1 tonnes of thrust is also fitted, supplied by Kort Propulsion. 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 660 hp @ 1600-1800 rpm through a Masson Marine W7400 reversible gearbox with 9.077:1 reduction. CELESTIAL DAWN is now the ninth vessel built by the shipyard in recent years to feature this propulsion package which has demonstrated itself to be both robust and adaptable with the Wide Operating Speed Range of the C32 main engine providing flexibility to achieve full power from a fixed pitch propeller both whilst steaming and trawling. CELESTIAL DAWN also features a triple rudder system and 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 kW and of 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 vessel’s 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 deck feature’s a catch handling system built by the yard and Northeast Fabricators and is complemented by a resin floor system fitted by Davidsons Marine & Industrial Painters. A separate compartment is formed within the fish processing area which house both the ice plant room and the fish hold access hatch arranged with a fixed permanent stair. The fish hold refrigeration system along with the ice machine was supplied and fitted by Airo-Tech Solutions.

The vessel was fully painted by Davidson Marine & Industrial Painters with International Paints products applied to a comprehensive marine spec.

The high specification navigation package was supplied and fitted onboard by Woodsons of Aberdeen, including the Scanmar net monitoring package along with a JFC transducer.

Fishing Vessel ‘Orion, BF 432’ – Press Release

Macduff Ship Design are pleased to announce the delivery of the new build fishing vessel, ‘ORION, BF 432’, to owner Brian Harvey and his two sons Andrew and Simon. This new build replaces their previous fishing vessel of the same name, which was built by Macduff Shipyard in the early nineties and is intended to fish around the coast of Scotland, predominately in the North Sea.

ORION was originally planned to be built from the yard’s previous 24.50 m hull model but during the early design phase, a decision was taken to remodel the vessel’s bow based on the preliminary results from a tank testing program which Macduff Shipyard and Macduff Ship Design were running for another project. A quick study was conducted by the Wolfson Unit in Southampton using CFD technology to compare the proposed new bow against the previous model with the results showing a net decrease in hull resistance at steaming speeds, as anticipated. Following this, the hull form was faired and finalised by Macduff Ship Design who then produced a full set of steel construction plans along with conducting the incline experiment and producing the vessels stability booklet. The fabrication of the hull of ORION was subcontracted to Kedat Shipyard based in Szczecin, Poland with the construction reviewed and verified by Bureau Veritas to comply with the MCA’s construction standard and upon completion, the hull was towed to Macduff for outfitting by the yard

The hull of ORION is built completely from steel, apart from the wheelhouse and mast, and features a double chine hull form, transom stern and modern bow designed to cut cleanly through the sea with less energy leading to a reduction in fuel consumption and emissions along with increased crew comfort. In broad terms, the layout of the ORION is largely like some of the other recent new builds produced by the yard. Below deck features the cabins, engine room, fish hold and a large freshwater tank forward of the collision bulkhead. Whereas above deck is situated the aft shelter, galley/mess and side passage area, fish processing area and then a winch room forward where the trawl winch is situated.

A bespoke hydraulic deck machinery package was fabricated by the yard for the ORION comprising of a triple barrel winch powered by dual motors, two split net drums, two bagging winches, two small gear handling winches, 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 Parker hydraulic pump driven from a dedicated Mitsubishi 6D24 auxiliary engine producing 218 kW whilst secondary hydraulic power is provided by the combination of one electric/hydraulic motor set with an output of 22 kW in tandem with a Parker hydraulic pump driven from a power take-off fitted to the main propulsion’s gearbox. A hydraulically powered bow thruster is also fitted with 180 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 660 hp @ 1600-1800 rpm through a Masson Marine W7400 reversible gearbox with 9.077:1 reduction. ORION is the seventh vessel built by the yard in recent years to feature this propulsion package which has demonstrated itself to be both robust and adaptable with the Wide Operating Speed Range of the C32 main engine providing flexibility to achieve full power from a fixed pitch propeller both whilst steaming and trawling. The efficiency gains predicted during the early design phase were realised during engine trials with the vessel achieving 9.1 knots at only 50% engine load and 10.5 knots at 100% load. ORION also features a triple rudder system and a 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 sufficiently sized 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 deck features a catch handling system built by the yard and is complemented by a DEGA resin floor system fitted by PBP services. Two separate compartments are formed within the fish processing area which house both a dry locker and ice plant room. The fish hold refrigeration system along with the ice machine was supplied and fitted by Premier Refrigeration.
