ViewPoint Spidercage: Successful simulation test of offshore fish farm

  • Sector: Sea
  • Date: October 6, 2018

  • Company: ViewPoint Spidercage develops an offshore fish farm based on the repurpose of existing offshore technology from the oil and gas industry in the demanding North Sea.

Spidercage is a offshore fish farm consept that consist of an outer barrier and an inner barrier. The outer barrier have active heave compensation and goes 12 meters (40 feet) below the surface. It acts as a wave breaker and protects against sea lice. The inner barrier have active heave compensation as well, and protects the internal pen so it receives less mechanical strain in demanding seas.

Spidercage allows remote operation, so a land based central can operate several spidercages simultaneously. This provides the basis for an efficient production and increased fish welfare. Nova Sea and ViewPoint applied four development permits for the concept in 2017.

The simulation test was carried out by MARIN (Maritime Research Institute Netherlands) in October. The results verified the consept operational in Hs 11 (significant wave height). This means that the technology enables fish farming in areas with demanding sea. Representatives from Nova Sea, Aibel, Moss Maritime, Aqua Knowledge and ICON Systems also participated in the testing.
