The 27-metre Eloise Eslea packs a lot into a relatively small space, including a thermal delouser that can treat 200 tonnes of salmon per hour.

Ocean Kinetics shows its mettle with second delouser installation

Shetland firm pleased with result of challenging task


Shetland-headquartered engineering and fabrications company Ocean Kinetics has expressed satisfaction for completing the “challenging” job of installing a thermal delouser on to a new multi-purpose vessel owned by Mull-based Inverlussa Marine Services and now in service for Scotland’s second largest salmon farmer, Scottish Sea Farms.

The project, which was delivered for main contractor, Scale Aquaculture AS, is Ocean Kinetics’ second installation of this kind for Inverlussa on its new hybrid aquaculture support vessels, which utilise battery hybrid technology to reduce emissions and carbon footprint. Both vessels were built by Dutch company Nauplius Workboats.

Bespoke design

Paul Wilson, project manager for Ocean Kinetics said: “Ocean Kinetics was commissioned to install the delousing system on the multi-purpose service vessel Eloise Eslea for Inverlussa and its customer, Scottish Sea Farms. Despite the challenging nature of the project, we were very pleased to complete to a very high standard with a 200-tonne per hour treating capacity.

Ocean Kinetics made much of the equipment for the delouser.

“The manufacturing team followed a bespoke design, manufacturing and installing dewatering tanks, treatment loop, chutes, cleaning, and suction equipment optimised to ensure gentle treatment of the fish while maximising throughput. The complete system is not only very efficient and operator friendly, it has been designed for minimal down time between salmon pen set-ups, ensuring that fish are treated quickly with minimal stress.”

The project follows the installation of a different system on Inverlussa’s first hybrid vessel, Eloise Isaac, where the main components were supplied by Norwegian company, Smir, for client Cooke Aquaculture Scotland.
