Ridgeway Rockbags successfully supplied the first “Kwoya Filter Units” from Japanese manufacturer Kyowa Limited for offshore wind turbine monopile sea scour protection in Europe. This patent protected application used a combination of the 4 & 8 tonne type Rockbags filled with specific aggregate in a circular formation around the monopole. Engineers where able to achieve tough design criteria set for sea and wave conditions.
