Ramnäs Bruk in the Aquaculture industry

Ramnäs Bruk  has signed a contract to supply mooring chain and accessories to Norwegian pilot offshore fish farm project.  Among other parties from the oil and gas industry Ramnäs Bruk has contributed with knowledge and long experience to create a reliable mooring system for this full-scale pilot project “Ocean Farm 1” offshore Frohavet, central Norway. The ocean fish farm is planned to be completed by the second half of 2017.

Mooring chain from Ramnäs Bruk will be used in the eight point mooring system securing the structure of a semisubmersible to the seabed. The rig for the fish farm is 68 meter high and has a diameter of 110 meters with a volume of 250.000 cubic meters. This permanently moored semi-submersible structure has favorable motion characteristics based on proven technology developed for optimal fish farming.

Ocean Farm 1 will be first of its kind in the world; the submerged facility has a generic design. This means that the design and operative experiences from this project can be re-used and the target is that an industrial production of this type of offshore fish farms can be started.

All studs are found without displacement in any direction and the same applies to the perfect impressions and indentations due to Ramnäs asymmetrical stud design and stud expansion process.    Read More>>
