INVERLUSSA LAUNCH NEW VESSEL, KALLISTA HELEN, ON THE CLYDE

8ac15bfd 648f 441a acdb 211af66a7b26

Launched today by Ferguson Marine (Port Glasgow) and on long-term lease to Scottish Sea Farms the Kallista Helen is a multi-purpose service vessel that will be fitted with a next generation Thermolicer.

Designed by Macduff Ship Design, the Kallista Helen will enable our clients to intervene earlier with regards to sea lice control, safeguarding farmed fish health. The Kallista Helen, named after managing director Ben’s niece Kallista Knight, was built with fish health and welfare front of mind. Scottish Sea Farms were looking to minimise fish handling and maximise fish welfare, as such the boat has been developed around these key requirements.

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


• 500-micron filtration to separate and collect the dislodged sea lice for removal from the marine environment.


In another first, the Kallista Helen has been custom-built to integrate the thermolicing system 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 at the end of April 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 on the West coast Mainland and Shetland area on contract to Scottish Sea Farms. 

Commenting on the collaboration between Scottish marine businesses, Rural Economy Secretary Fergus Ewing said:

‘I welcome this partnership which is using innovative technology to address key challenges faced by the sector. Aquaculture is a vital sector for Scotland’s economy, creating many highly paid, highly skilled jobs across the country, many of which are in rural and remote communities. The Scottish Government is committed to supporting the sustainable growth of Scottish aquaculture and its wider supply chain.’
