The client Arctic Offshore Farming will have completed the plant in the sea off the Norwegian city of Troms by the third quarter of 2020. Equipped with state-of-the-art technology, the fish farm will be more efficient and at the same time more environmentally friendly than the previous systems. It is connected to ABB Ability, a digital platform that incorporates environmental data, meteorological data, current conditions, temperature and oxygen content in the sea. The system also measures the pH values at different depths and the biomass in the cages.
In the new submersible fish farm on the open sea, the salmon will be reared more sustainably than in fish farms located in the fjords. This is because the fish in the underwater cages are less susceptible to pests such as sea lice. The sea lice had led to a decline in Norwegian salmon production in conventional facilities. Norway is one of the largest salmon exporters in the world. Salmon rearing in a healthy and environmentally friendly way is particularly important in order to meet the increasing global demand. By 2023, 4.5 million tonnes of salmon are to be sold worldwide.
Reaching such a facility in the Norwegian Sea is not easy because it is exposed to much harsher conditions than the facilities in the fjords. A special system, which dynamically distributes the water ballast to the ballast tanks according to the respective conditions, ensures that the fish cages lie stable in the water.
"This concept allows us to show very well how ABB can contribute to sustainable and efficient aquaculture," says Kevin Kosiko, Director ABB Energy Industries. "The unmanned fish cages are remotely controlled from a barge anchored 400 meters away. This eliminates the need for human visits, reducing fuel and energy consumption. In addition, completely new approaches in fish farming can be promoted, which focus on the welfare of the fish, the traceability of their rearing and food safety."
