Contract for ultra-sustainable live fish carrier

Norway’s HAV Design and Norwegian Electric Systems (NES) have won a NOK 90 million contract for a live fish carrier which claims to have the smallest environmental footprint per unit of transported salmon. The vessel has been ordered by Frøy AS and will operate for Norwegian salmon farming company, Cermaq.

The design has been developed in close collaboration with both Frøy and Cermaq. Features include cylindrical tanks with a total capacity of 6,000m³, enabling higher fish density, reduced oxygen consumption, and a lower stress level for fish, the company said. More deck space is available for high-throughput delousing equipment and fresh water production.

NES will supply the energy production and propulsion systems. Batteries and variable speed generators will enable longer spells of operation on renewable energy. Meanwhile, residual heat from the engines’ cooling water will be used for heat on board, and residual heat from the exhaust and cooling water will produce electrical power. NES will also deliver an integrated bridge system equipped with dynamic positioning.

Senior designer in aquaculture business at HAV Design, Kjetil Myren, commented: “We have drastically reduced energy consumption on board the ship. And when the tanks can also hold more fish, while enhancing fish welfare, we are confident in saying that this is the live fish carrier with the smallest climate and environmental footprint in the world per kilo of transported salmon.”
