World’s First Freshwater Treatment Wellboat
Bakkafrost’s Hans á Bakka is a milestone vessel in aquaculture, combining high-capacity live fish transport with advanced freshwater treatment systems. Built to improve fish welfare, enhance operational efficiency, and reduce biological risks, the 75-metre vessel can carry 450 tonnes of live salmon, more than double the capacity of Bakkafrost’s previous flagship.
With Bergen Engines powering the vessel’s diesel-electric propulsion system, Hans á Bakka delivers reliable, fuel-efficient performance that allows the operator to maintain precise control over fish handling, transport, and treatment.
Key Facts
Reliable Propulsion Power
At the heart of Hans á Bakka’s propulsion system are two Bergen C25:33L6 engines, each rated at 1,920 kW. Integrated into the vessel’s diesel-electric setup, these engines provide the thrust and operational reliability needed for demanding aquaculture operations.
Bergen’s reputation for durability and fuel efficiency ensures that the vessel maintains consistent performance across transport and treatment tasks while keeping operating costs competitive.
Looking Ahead
As part of a growing fleet of technologically advanced wellboats, Hans á Bakka demonstrates the benefits of combining Bergen Engines’ reliable propulsion with innovative fish-handling technology.
The vessel’s success underscores the importance of ownership in enabling operators to develop and optimize new treatments, positioning Bakkafrost as a leader in sustainable, high-quality salmon production.
