Work at the 576MW project in the Irish Sea will commence again from the Tideway Rollingstone vessel on 21 September.
Scour - the movement of sediment that can erode the seabed around a fixed structure – is a major concern when designing offshore wind projects, and developers must take preventative action to avoid the weakening of foundations.
Bladt Industries fabricated the monopiles in Lubmin, Germany. All 160 foundations were installed by August 2013.
The project is nearing completion, with all 160 Siemens 3.6MW turbines installed, and half of them now operating. The inter-array cabling – the last major work on the development – is due to be completed this autumn.
