Subsea excavation and trenching pioneer, Rotech Subsea, has completed a programme of cable IRM works at a key offshore wind farm in the Netherlands. Commissioned by a European subsea service provider, Rotech’s RS2 CFE (controlled flow excavation) tool from its industry-leading RS range of trenching and excavation equipment was mobilised from Aberdeen in Q3, 2021. The cable repair operations saw the RS2 de-bury approximately 800m of existing cable before carrying out the burial of new cable, with a September 2021 completion date.
