Aquaculture workboat
Macduff Ship Design recently celebrated 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 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. 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.
