Wind Energy – Rockbags
Belfast-based Ridgeway has secured a contract with its first French client to use Kyowa Filter Units, known as Rockbags.
Saint Nazaire is a 480MW offshore wind farm being developed in the Loire-Atlantique region of France and it is owned by EDF Renewables and EIH S.à r.l. (Enbridge Inc. et CPP Investments)..
It will deploy the sustainable Rockbags for protecting and stabilising sections of the cable.
Rolf Slomp, Offshore Installation Manager for Louis Dreyfus Travocean, responsible for installing the array cables, explains the importance of this control method: “The Rockbags are ideal for stabilising our cable. Having the rocks of this size in the bags it envelops the cable and CPS nicely without having to dump a huge number of rocks. The Rockbags together with the crane, beacon and ROV give us a precision stabilisation of the cable with a minimum of materials installed on the seabed.”
The eco-friendly Rockbags are mainly used for protecting underwater cables and pipelines, as well as stabilising structures.
