Sister Ships Launched

The pair-seiner ‘Crystal River’ FR 178 was transported to the slipway at low tide using specialist low loader units. With the low loaders removed, 6 hours and a large spring tide later, she was towed to her fitting-out berth to complete the final works. At the same time, the sister ship ‘Faithful’ FR 129 left Macduff for final trials before heading to Fraserburgh for preparations to go on her maiden trip. We are proud to have provided Naval Architecture services to Macduff Shipyard for these designs and wish the skippers good fishing and safe seas.

Wide Range Of Vessels Surveyed In May

Wide Range Of Vessels Surveyed In May

The past few weeks has seen our staff carry out surveys on a wide range of vessels. 

The Shapinsay, an Orkney based ferry that has been dubbed Scotlands first hydrogen-powered ferry, was down from the Islands to Peterhead to undergo its 5-year survey. The vessel is fitted with 8 large cylindrical hydrogen tanks that will be used to power auxiliary systems on board.  The hydrogen tanks will be filled using the successful Surf ‘n’ Turf project which turns excess green energy into hydrogen. We carried out a successful lightship survey on the vessel which has made its way back to Orkney. 

We also attended an inclining experiment in Hull at the MMS yard to survey their new yacht which has been built for private ownership. The 55ft trawler yacht has been designed by us to have a layout that is beneficial for liveaboard yacht owners and a hull designed for long-distance cruising. We look forward to sharing interior photos once the outfitting has been completed. 

Finally, it was back to Peterhead to undertake another lightship experiment, this time on the 79m purser ‘F.V. Pathway’. Having only been delivered to her owners in 2017 this was her first 5-year interval survey. No issues or concerns arose from our survey and the vessel is now preparing to go back to sea.

Kallista Helen

Kallista Helen

A new aquaculture vessel with a focus on fish welfare has been launched on Monday (15/3) by Ferguson Marine. The 26-metre boat is the latest addition to the Inverlussa Marine Services fleet and the 6th vessel launched that has been built to plans by Macduff Ship Design. This cements the long-lasting partnership between Macduff Ship Design and Inverlussa Marine Services as they continue to expand their fleet.

The £6M Kallista Helen is a multi-purpose service vessel that is to be fitted with a £2.5M next-generation Thermolicer. This will enable the salmon producer to intervene earlier with regards to sea lice control, helping safeguard farmed fish health.

Ben Wilson, Managing Director of Inverlussa, said the Kallista Helen, named after his niece, was built with fish health and welfare front of mind.

‘From the outset, Scottish Sea Farms was looking to minimise fish handling and maximise fish welfare, designing the boat around those. The result is so much better when you start with the fish then consider the boat, rather than the other way round.’

Central to the vessel’s bespoke design is the Thermolicer itself, designed and engineered by ScaleAQ in Norway in partnership with ScaleAQ UK.

The first of its kind to be constructed in Scotland, the system includes:

  • A simpler, straighter pipe layout creating a gentler experience for the fish
  • A wider than standard pipe of 600mm diameter to ensure a smoother journey through the system
  • Increased capacity of up to 120 tonnes per hour
  • 150-micron filtration to separate and collect the dislodged sea lice for removal from the marine environment.

In another first, the service vessel has been custom-built to house this delousing technology internally within a dedicated sheltered deck to protect it from the elements; the advantages being better operational efficiency, improved seaworthiness and safer working conditions for the crew.

It also frees up more space on the vessel’s top deck for equipment, including three cranes which means the vessel will be less dependent on other workboats during treatments.

Meanwhile, down in the engine room, there is a heat recovery system to draw heat from the engines and transfer it to the delousing system, saving on both fuel usage and carbon emissions.

Scottish Sea Farms Managing Director Jim Gallagher said: ‘Not only is the Kallista Helen another important step forward in our drive to ensure the best growing conditions for our fish, it’s also a great example of Scottish business supporting Scottish business from drawing board through to final deployment.

‘Events outside everyone’s control have caused delays but we’ve stuck together throughout, stayed focused on the end goal and now we’re back on course.’

The Kallista Helen is expected to arrive in Shetland in early May where it will be fitted out by Scale AQ’s Scottish team and Ocean Kinetics of Lerwick.

Once works are complete, the vessel will operate with two five-strong crews – one from Scottish Sea Farms, the other from Inverlussa – each working three week on/off shift patterns.

Endeavour V Handover

Endeavour V Handover

FISHING VESSEL  ‘ENDEAVOUR V’ – PRESS RELEASE – 12.02.2021

Macduff Ship Design are pleased to announce the delivery of the Stern Trawler MFV ‘ENDEAVOUR V’.  The vessel completed by Macduff Shipyards was the fifth to be built by the yard for skipper Peter Lovie of Knockhead LLP of Whitehills, compounding a working relationship of over thirty-five years culminating in the largest vessel ever delivered by the yard.

The project began in the summer of 2017 when the owner expressed an interest to build a new fishing vessel with a desire to improve fuel efficiency, service speed and sea keeping from their existing vessel. An early study between the yard and Macduff Ship Design concluded that to achieve this a longer ship, free from the constraints of registered length, would likely be required. It was at this point that the Wolfson Unit based in Southampton was contracted to complete an initial trial using CFD technology to assess the differences in calm water hull resistance between the existing model and a new longer concept model. As expected, the data showed that a significant reduction in hull resistance could be achieved with a longer hull form, however, the computational based analysis could not assess the differences in sea keeping qualities. To answer this question the Wolfson Unit conducted a further trial but this time towing representative scale models in the Solent University Towing Tank facility. Both hull forms were assessed at a range of speeds in both calm water and head seas with wave properties reflecting those found in the north Atlantic where the owner typically operates. As well as confirming the reduction in hull resistance between the two models the tank testing also enabled sea keeping to be measured and it was conclusive that longer hull experienced considerably less pitching motions along with lower bow impact from wave force.

With the research complete the yard and Macduff Ship Design took one final review of the hull form and the decision was made to lengthen the hull by a metre to seek further improvements in hull efficiency as well as affording a little more space within the vessel.

With the hull lines faired and stability assessed by Macduff Ship Design, the construction plans were then drawn up and submitted to Bureau Veritas classification for approval along with the outfitting and engineering drawings. These were then supplied to Finomar Shipyard based in Szczecin, Poland who were sub-contracted to fabricate the hull and wheelhouse which upon completion was towed to Macduff in November 2019. The full outfitting was completed in Macduff to MCA and BV regulations with the vessel departing Macduff, less than one year after arriving, to Fraserburgh where it was docked for a final paint. Sea and fishing trials were conducted in the Moray Firth before the vessel was signed over to the new owners who departed their maiden trip, fishing off the west coast of Scotland. Early indications are that the hull is performing as anticipated with increased speed, reduced fuel consumption and improved sea keeping evident.

The hull form is of round bilge with a streamlined bulbous bow, flared stem, beam carried full length to the transom and possesses two complete decks, as well as partial shelter and bridge decks. A ballast box keel is fitted along with deep ‘V’ bilge keels and a roll reduction tank to dampen roll motion.

Endeavour V features four deck levels which apart from the bridge deck all run the full length of the ship. The arrangement is based closely on the successful Endeavour IV which has proven itself well over the years but makes use of the additional space to increase crew comfort, fish hold capacity and working deck areas.

Below main deck is separated into four compartments; aft peak, engine room, fish hold and forepeak.

The aft peak features numerous tanks used to house both fresh water and ships services such as lubrication and hydraulic oil.

Forward of this, the engine room houses the main propulsion machinery which is provided by a MAK 8M20C engine rated at 1060 kW at 900 rpm coupled to a free-standing Mekanord 650HS reversing gearbox with a reduction ratio of 6.47:1 which drives the large 3.3 m diameter controllable pitch propeller. A low drag high thrust nozzle is fitted in way of the propeller and incorporates a triple rudder system to provide high turning force. Two Caterpillar C9.3 generator sets are fitted to the port side of the engine room, each delivering 250 ekW of power along with the hydraulic standby pumps and fuel filters. To the starboard side of the engine room, the large main switchboard is fitted within a dedicated enclosure along with a small workstation to provide a place for the ship’s engineer to monitor and record system performance. Forward of the switchboard room, the fish hold refrigeration is fitted along with the standby engine cooling pumps. The main engine and generators are cooled via freshwater box coolers. A hydraulically powered stern thruster is fitted aft above the propeller shaft with motor fitted in the engine room.

A large fish room is fitted forward of the engine room with capacity for up to 2,200 stacking fish boxes. Refrigeration was achieved with chilling pipes fitted to the ceiling of the hold as well as below the floor where they were incorporated into the subflooring. The fish hold refrigerant is liquid-based which poses no danger to life if a leak occurs and can be easily mended onboard. Ice lockers are arranged in the hold and can house up to 10 t of flake ice, in addition a slurry ice mixing tank if fitted to provide premium chilling for certain species.

At the stem of the vessel, the forepeak is divided into four compartments with three large freshwater tanks which are used for ice-making along with a bow thruster access compartment on the centreline.

Above the main deck, the vessel is generally divided along the centreline with working areas to port and accommodation to starboard.  To the port side, there is a steering gear compartment combined with engineer’s workshop aft, fish handling area amidships and dry locker forward. To the starboard side, there is a laundry/pantry/galley aft, followed by a large mess/lounge amidships and four two-man cabins forward. A large 20 m3 hopper is fitted on the centreline.

A deck up features the trawl deck where most of the deck machinery is installed and fishing takes place. The deck features twin ramps aft with hydraulic stern gates fitted to the top of each ramp for crew protection. Forward of these is two flush-mounted hopper hatches where the catch is taken on-board. The deck is then open all the way to the stem where three sweep winches are fitted to allow maximum deck length for storing and mending nets. Fitted amidships immediately above the net tracks are three separate bagging winches. Three split winches are fitted amidships, two to starboard and the third to port and lead directly aft to large trawl blocks which are capable of sliding forward up to 1.2m from the transom to reduce the pressure on the steering gear when towing an edge in deep water. Numerous casings are fitted on either side of the tracks and serve various functions such as a gear store, air handling unit room, two-man cabin and unloading trunk.

The shelter deck runs from stern to stem. Aft it is mainly open and provides a walkway around the perimeter of the vessel as well as shelter for those working on the trawl deck. Amidships features a full breadth casing where three two-man cabins are fitted along with an electronics room. Forward is arranged for mooring and anchoring and features a three-barrel winch fitted within a weathertight compartment and is used to stow the two anchor warps along with a spare barrel for mooring ropes.

At bridge deck level a large wheelhouse is situated which is nearly the full breadth of the hull to provide great visibility when manoeuvring in restricted areas. Large windows are also fitted aft on the centreline and provide a commanding view of the trawl deck to enhance crew safety.
