Rampion was the first offshore wind farm off the south coast of England and is owned and operated by RWE Renewables. The O&M base is a permanent structure, located within the Port of Newhaven comprising offices, warehousing and berthing and quayside facilities for the wind farm commissioning and maintenance vessels.

Working with civil engineering firm Knights Brown, ICMS designed and installed a 90 linear metre concrete breakwater with 1m freeboard, suitable for berthing CTV vessels up to 140T displacement. The floating structure, with external pile guides, has a width of 4.5 metres providing ample space for the associated electrical, water, lighting and fuel services required.
