Wellboat operator orders new vessel with focus on the future
Norwegian aquaculture logistics operator North Salmon Service (NSS) has ordered a new live fish carrier with a well capacity of 5,000 cubic metres.
The vessel, designed by HAV Design and to be constructed at Fitjar Mekaniske Verksted in Norway, is based on the newly developed HAV 595 design – a versatile platform tailored to meet a wide range of operational requirements.
“NSS and our customers – Nova Sea and Salten Aqua – have focused on ordering a vessel that is future-oriented and delivers on the customers’ high demands for biosecurity and fish welfare,” said NSS managing director Arnt Erling Paulsen.
“NSS has together with HAV Design chosen a ship design that is flexible and adaptable to alternative energy sources. We have at the same time focused on reducing the vessel’s fuel consumption.”
New benchmarks
The HAV 595 design supports a wide range of live fish operations, including transport and sorting. It offers greater operational capacity than current industry standards and is said to set new benchmarks in biosecurity, fish welfare, cost-efficiency, and environmental performance.

“Our HAV 595 enables more gentle and efficient handling and transport of salmon and sea trout. The hull is energy-efficient and onboard systems are designed to reduce overall energy use,” said Jan Magne Goksøyr, vice president sales at HAV Design.
The vessel is equipped with hybrid propulsion – including variable-speed generator sets, DC distribution, and a large battery pack – which reduces energy consumption, increases operational flexibility, and paves the way for alternative energy sources.
“We’ve worked closely with North Salmon Service on this next-generation design, which can also be adapted for other owners,” added Goksøyr.
Insight and digital tools
Kjetil Myren, senior designer at HAV Design, said: “In-depth operational knowledge is essential to designing vessels that not only meet but exceed customer expectations while reducing environmental impact. By combining operational insight with digital tools from HAV Ocean Lab, we are able to achieve just that.”
The vessel is scheduled for delivery in 2027.
“We look forward to collaborating with Fitjar Mekaniske Verksted. While this is our first project together, they have made a strong impression and we are confident that they will deliver a high-quality vessel,” concluded Jan Magne Goksøyr.
