Salmon farmer will replace 40,000 gallons of fuel with shore power
Two hybrid vessels owned and operated by Trident Aqua Services can operate all day on batteries, reducing Hofseth's carbon footprint
Two hybrid workboats that will contribute to significant reductions in fuel consumption, CO2 emissions, and noise have gone into service for Norwegian salmon farmer Hofseth.
The Multi Storfjord and Multi Navigator, owned and operated by Trident Aqua Services, are tailored to work in close interaction with Hofseth’s land-based infrastructure, enabling more efficient and future-oriented operations.
Through connection to Hofseth’s shore power facilities, the vessels can operate with minimal use of fossil fuel. Multi Storfjord is fitted with a 1500 kWh battery pack, while Multi Navigator has an 1125 kWh battery pack, allowing both vessels to operate solely on battery power for a full 12-hour working day.
Designed by Solstrand Trading and built at Sletta Verft, with a focus on high operational performance, electrification and biosecurity, the boats are equipped to handle a wide range of activities, from mooring work to advanced service operations.
With integrated systems for remotely operated vehicle (ROV) operations, net cleaning, and electrically driven pump solutions, work can be carried out within controlled parameters with reduced risk of cross-contamination. This provides increased control and more efficient use of resources, while supporting strict requirements for fish welfare and disease prevention, Trident said in a press release.
Between them, the vessels will have an estimated daily energy consumption of 2,420 kWh drawn from shore power. On an annual basis, this replaces approximately 200,000 litres (44,000 gallons) of fuel, assuming daily charging and normal operations.
“As the world’s largest provider of vessel services to the aquaculture industry, we have a responsibility to drive development forward,” said Trident chief executive Arild Aasmyr. “These vessels show how we combine technology, experience and innovation to deliver solutions that create real value for our customers.”
Roger Hofseth, chief executive of Hofseth, said the boats fit well with how the company wants to develop the future of aquaculture in Storfjord, where they are operating.
The two vessels will be officially named at a ceremony taking place on Saturday, June 13 in Ålesund, Norway.
