LONGEST SEA CABLE TO A FISH FARM IN THE FAROE ISLANDS

LONGEST SEA CABLE

Longest sea cable to a fish farm in the Faroe Islands. JT electric have just completed the latest installation of their 5.6 km long sea cable to a Bakkafrost site in the Faroe Islands. The cable provides power from land to the remote fish farm and is the longest of its kind in the Faroe Islands.

This installation is part of the Bakkafrost driven transition to provide more sustainable power consumption. The majority of the Bakkafrost feeding barges in the Faroe Islands are powered by sea cables from land, whilst the remaining are in the process of the shift. These sea cable projects have been organised and installed by JT electric throughout the Islands.

“Our goal is to reduce our CO2 emission with 50% by 2030,” says Jón Purkhús, farming manager for Bakkafrost North. “By using sea cables to supply our feeding barges with electricity from land we are reducing oil usage and thereby significantly reducing emissions from our fish farms.”

Designed by JT electric and their cable partner, this unique 5.6 km sea cable is fitted with fibre inside. Installing the fibre connection along with the power supply has ensured that the site has a fast and safe link to the equipment onboard the feeding barge. All operations are undertaken remotely from the land based feeding central, therefore this smooth connection is essential.

“This has been an exciting project for us,” comments Leivur Hansen, Operational Manager for JT electric. “The long distance required that we use high-voltage electricity to effectively deliver power via the sea cable to the feeding barge. This challenge was solved in close collaboration with Faroese electricity provider SEV.”

The OceanCable is a wear-proof marine cable used by fish farmers around the world. It is used to supply electrical power to and between farming cages, underwater lights, and other sea-based installations.

The renowned blue cable is produced from high-quality materials and is designed for use in extreme weather conditions. It has a virtually unlimited life expectancy when in an undisturbed installation. Should the cable require replacement, it is normally due to physical damage rather than wear. OceanCable does not require a conduit or tube; it can be installed directly into the sea.

The outer sheath is produced out of highly wear-proof PU (Polyurethane) surrounding the individual conductor insulation. Such construction ensures a very strong cable and protects the copper from wear. The core covering is replaced with insulation – extruded polyolefin compound – that gives it high flexibility. The conductors consist of stranded, flexible copper.
