If the project is completed as it has been designed, it will be the longest ship in the world.
For reference, the world's largest cruise ship is 360 metres long. The longest hangar ship in the world, the American USS Enterprise, is 342 metres long.
One Havfarm will be able to contain 10,000 tons of salmon - over 2 million fish. For comparison, the Nordlaks salmon slaughterhouse at Børøya produces 70,000 tons a year. The facilities will be able to withstand a significant wave height of ten metres, and can be raised by four metres during inclement weather. The ocean farm itself will extend ten metres below sea level. The farm will be constructed as a steel frame for six "cages" measuring 50 by 50 metres on the surface, with aquaculture nets going to a depth of 60 metres.
At the time Inge Berg from Nordlaks contacted us, we had previously been flirting with the idea of producing a larger construction from scratch. Berg came up with a very thorough idea of how to move from aquaculture pens to aquaculture ships in the open ocean, says sales manager Thomas Myhre.
Because steel louse skirts at a depth of ten metres will make sea lice history. When the Havfarm lays at anchor, the spreading area for waste products will be 27 times larger than it would be for ordinary pens, a massive 472,000 square metres. To the extent lice may appear on the salmon, the farm can facilitate the manual removal of sea lice. This also provides a totally chemical-free production. The use of chemicals to remove lice has been a much-debated environmental issue, and has been a major expense for the industry as well. This will change the direction of the aquaculture industry, which has been struggling due to such issues.
