Scour Protection

Energy transition towards sustainable power generation affects the offshore wind energy sector greatly. Due to extensive research work and technological developments, the number of foundation types for offshore wind energy plants has increased significantly. Independent of foundation type, each structure influences the ecological and hydrodynamic regime surrounding the structure. As a consequence, local flow turbulences may cause scours at the seabed and can lead to a reduction of structure stability. Geotextile sand containers (GSC) are an approved method for scour protection. During installation of scour protection systems, the sinking behaviour of GSC is affected by translational and rotational movement, which impedes an accurate positioning of GSC. Physical model tests have been conducted to analyse the influence of container shape and material properties of GSC. This paper presents the results of these model tests.
