In recent years research on scour around subsurface structures in the offshore wind environment has gained momentum due to the accelerated demand for renewable energy. This study looks at the use of collars to modify the downflow, the main driver of scour, and reduce the horseshoe and lee-wake vortices, thus reducing local scour depths. For measurement of scour in this study, acoustically transparent Mylar film was applied to the surface of the collar, enabling continuous recording of the scour processes beneath the collar, whilst simultaneously preventing the water and sediment passing through the collar. This enables measurement of scour development throughout the experiments until an equilibrium bed state was developed. Three different collar diameters were investigated at five different heights from the bed with data showing that the larger collars closer to the bed have a higher potential to mitigate local scour depths.
