Most sustainable salmon transporter developed

HAV Design and Norwegian Electric Systems have developed what they are claiming is world’s most environmentally friendly salmon transporter. The vessel was ordered by fishing company Frøy AS and will be put into operation by Salmon farming specialist Cermaq after delivery.

The new design is a further development of the well-known Havtrans vessel series, through which the company has developed its expertise in designing live fish carriers with cylindrical tanks, having delivered six such designs since 2014. This new design’s capacity is nearly doubled, with a tank volume of 6,000m divided between four cylindrical tanks.

The vessel has been developed in close cooperation with Frøy and Cermaq. Cermaq has operated one of the ships in the Havtrans series, Steigen, for many years, and has seen how the fish density can be increased while still achieving a lower level of stress and oxygen consumption than in conventional tank systems.

The energy production and propulsion system onboard the vessel will be delivered by Norwegian Electric Systems (NES). It will consist of a DC-system powered by batteries and variable speed gensets. According to NES CEO Geir Larsen, this means lower fuel consumption per kWh produced and reduced noise level from the ship which is something the crew, local communities and the salmon will all appreciate.

The ship will be prepared for the use of climate-neutral biofuel, and the onboard battery pack combined with large shore power capacity enables operation for longer periods on renewable energy.

Residual heat from the engines’ cooling water will be used for onboard heating, while heat from the exhaust and cooling water is used to produce electric power – both contributing to even better energy efficiency.
