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.
Ridgeway supplied Global Offshore with 111 x 2T filter units specified for subsea cable stabilisation off the Orkney Islands. Working with the engineering and procurement team within Global Offshore, Ridgeway provided 2 separate orders of filled filter unit rockbags on the quay side under crane hook prior to the vessel arriving into Kirkwall Port.
