By 13 June 2014, RWE Innogy and Visser & Smit Marine Contracting had completed installation of the inter-array cabling at the Nordsee Ost offshore wind farm, creating a network of over 60 kilometres of 33 kV subsea cables in less than four months. Using the vessels Normand Flower and Stemat Spirit in two installation campaigns, all 48 turbine foundations and the substation foundation were linked in cable loops, with the cables laid, buried to around 1.5 metres, and their final positions and integrity verified by ROV surveys.
