Problems can arise in day to day operations of offshore wind farms and hydroelectric power plants and dams, whereby there are events of high scouring at the base of monopiles or high aggregation of bedload and suspended sediment at intake structures. Although deep water floating wind turbines are being developed, most offshore wind farms still utilise traditional fixed-bottom foundation technologies (ref 1).
The different type of foundations include monopile, gravity based, tripod, suction bucket and conventional steel jacket structures. Of these, monopile foundations have been the preferred foundation type so far, simply because they have an edge over other foundation types in shallow water, with regards to construction, production, assembly and cost efficiency. Over the years, there are numerous papers written on the subject of scour behavior for monopile foundations as well as a number of text books on scour at the seabed (ref 2, 3, 4). The effect of scour or erosion of sediment in the vicinity of a structure can potentially be detrimental to the stability of the structure and its fatigue life.
