OFFSHORE FISH FARMING CAGES

FISH FARMING CAGES KJ has produced Offshore Fish Farming Cages since the early 1990’s. The cages are specially designed for the most exposed conditions around the world. The steel bracket is the most used bracket in the Faroe Islands, strong and solid and easy to install, this is the best solution for the strongest cages. Tested in rough and harsh conditions of the shores of the Faroe Islands.

The cages have been tested at open sea in up to 18 meters waves and load tested with 50 ton pull load by the Faroe Islands natio- nal fish farming company www.fiskaaling.fo

Strong galvanized all-welded steel brackets with PE handrails and fully integrated plastic panel walkways fits securely between the floating pipes forming stable and safe working conditions. Double or triple floating pipes in PE100 polyethylene plastic.

Plastic bushings between the steel brackets and the floating pipes increase the service life of the cage and makes the pipes self-cleaning from growth.

Polystyrene or Styrofoam core makes the secondary safety system all around the circumference secures the assets if a fracture or damage to the floating tubes were to occur.

OFFSHORE FISH FARMING CAGES By combining the flexibility of plastics with the strength of steel, KJ has constructed a net cage system that satisfies the present day high requirements to strength and safety.

Float pipe dimensions available: ø200mm, ø225mm, ø250mm, ø315mm, ø450mm and ø500mm.

BRACKET

There are about 600 cages on the shores of the Faroe Islands. 97% of them are with steel bracket.

The sinker tube consists of a 280 to 400mm PE pipe filled with wire at specified weight attached with chain or dyneema ropes.

The double anchor bracket is strong and solid with built-in tube for the anchoring.

Mooring attachments are standard equipment and secure proper attachment of the moorings. The double anchor bracket is tested with +50 ton pull load.

In March 2015 KJ delivered 14 cages 100cir to Grieg Seafood in Shetland.

KJ has manufactured around 300 cages the last 5 years. The main sizes are 128 meters and 160 meters. But the cages can be produced in several sizes.
