Marine Vessel ‘Kallista Helen’ – Press Release

 

Macduff Ship Design are pleased to announce the delivery of the Aquaculture, Thermolicing Vessel MV ‘KALLISTA HELEN’. The first of its type to be designed and built-in Scotland. The vessel, completed by Fergusons Marine Engineering, is the fifth to enter service for Inverlussa that has been built to plans from Macduff Ship Design, compounding a long working relationship culminating in the most innovative design delivered to Inverlussa yet.

The project began in the summer of 2018 when the owner expressed an interest to build a new state of the art de-licing vessel with fish health and welfare front of mind. Scottish Sea Farms, who the vessel will be on contract with, were looking to minimise fish handling and maximise fish welfare and it was these key requirements that the vessel was built around.  Events outside of everyone’s control have caused delays to the project however she has now been delivered to the owners and is completing final outfitting and commissioning of the Thermolicer equipment in Shetland.

Central to the vessels principles is a Thermolicer designed and engineered by ScaleAQ and the first of its kind to be constructed in Scotland. A sudden rise in water temperature is a well-known method of killing lice so the Thermolicer has been developed to bathe the fish in temperate water for a short period. This will cause the lice to die and fall off the fish, after which they are separated from the water using a 500 – micron filtration system and collected to be removed from the marine environment. Wider pipes with an overall straighter and simpler layout have been utilised to create a gentler experience for the fish. This method allows for de-licing up to 120 tonnes per hour of fish.  The system allows for high levels of fish welfare and, as the process only utilise seawater, at the same time avoids pumping any chemicals into the sea. The system is at the heart of fish welfare which is what the boat has been built around. To protect this asset, it has been enclosed in a dedicated shelter deck to shield it from the elements. In turn, this provides a safer working environment for the crew as well as better operational efficiency and improved seaworthiness. Additionally, it provides a large area on the top deck for cargo and equipment, namely 3 H.S. Marine AK 40 cranes. The 40 ton/m cranes have a max outreach of 15.1m and can all work simultaneously without any restrictions. This capability allows the vessel to operate the entire system including all intakes and return systems and the vessel will be less dependent on other workboats while on site. Incorporation of cargo space and container latching points in the top deck allows for the haulage of ISO tanks should it be required.

The systems and machinery onboard have a high peak electrical load, resulting in a large engine room that spans over half the length of the hull.  Propulsion is derived from 2 x Cat C32 main engines delivering a total power of 1300hp, the engines are paired with two ZF W1800 reverse reduction gearboxes.  The shafts are connected to twin fixed pitched 1500mm propellors which are combined with low drag nozzles, supplied by Kort propulsion, to improve free running speed whilst maintaining a bollard pull of 15 tonnes.  The vessel is also fitted with high lift rudders by Wills Ridley and a 250 Kw hydraulic bow thruster by Kort Propulsion which ensures the excellent manoeuvrability required when working in and around the salmon farm. Two Cat C32 generators are also installed, providing 860kW each. These generators are used to power the thermolicing equipment, including the heating elements used to warm and maintain the temperature in the 22,000 Litres of seawater contained in the fish treatment system. They also provide power for the fish pumps and a 130 m3/h pump which is used to fill the system. The pumps used to bring the fish on board to begin the treatment are large vacuum pumps as these are relatively gentle on the fish and offer high fish welfare. To properly delouse the fish the system’s water is required to be at 28⁰C to 34⁰C depending on seawater temperatures however, there is a heat recovery system in place to draw heat from the engines and transfer it to the delousing system, saving on both fuel usage and carbon emissions. Smaller Cat C4.4 auxiliary engines are also used to power ships systems when the main generators are not in use.

With the ability to carry over 56m3 of fuel and over 40m3 of freshwater, the vessel has the ability to stay at sea for an extended period.

Forward of the engine room below deck sits 4 cabins with bathroom facilities. Careful consideration was made in respect to the accommodation area to ensure maximum crew comfort and insulation from engine room noise and vibration. Each cabin is equipped with heating, flatscreen T.V.’s, working desk, washbasin with mirror light and shaving socket as well as usual amenities to be expected. Above these cabins, on the main deck, a well-appointed galley/mess/lounge sits alongside the large dry locker. The dry locker incorporates engine room access, a shower room, access below to the cabins and access up towards the wheelhouse. Accommodation on the fo’c’sle deck is comprised of two single man cabins with a bathroom, an A/C and electronics space as well as a dedicated control room for the thermolicing equipment. Moving up to the large wheelhouse which gives a commanding 360-degree view with particular emphasis over the aft deck area thanks to the floor to ceiling windows. From here, aft control positions have been arranged port and starboard to allow for greater flexibility. There is also additional crew seating, a ships office area and a client office workspace within the wheelhouse.

We are thrilled to have been part of this project which showcases Scottish maritime strength with local businesses supporting each other, from initial design and conception through to the final deployment. Following completion of the vessel in Glasgow in May the ‘Kallista Helen’ departed for Shetland for final outfitting with a short stop at her homeport of Tobermory. Following the installation of the thermolicing equipment, she will go on a long term charter to Scottish Sea Farms.

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.

April Surveys

April Surveys

The good weather recently has been very welcomed by our staff who have been out of home-office for a series of surveys. An inclining experiment on the ‘Quantus’ was carried out over multiple days to ensure that the 65m fishing vessel continues to meet stability criteria. At the same time, we attended the Graemsay, an Orkney ferry, to undertake a lightship survey.

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.
