Sharing knowledge - Marine Donut project

Marine Donut is a pioneering closed containment facility addressing the needs of future fish farming. The concept has been awarded development permits by Directorate of Fisheries due to its potential to solve many of the environment and area challenges that the industry is facing.

With SalMar as project owner, the construction of the first Marine Donut is underway. Here you can follow the project's knowledge sharing.

2015

Nils-Johan Tufte has the idea for a donut-shaped closed containment facility. The concept development starts.

2018

SINTEF conducts a pool test of a 1:10 scale model with promising results.

2019

The Directorate of Fisheries awards a development permit to test the Marine Donut concept on a full scale.
