Offshore construction has started at the Hollandse Kust West wind farm, where Van Oord and developer Ecowende are installing eco-friendly scour protection designed to improve marine biodiversity.Van Oord’s subsea rock installation vessels Nordnes and Bravenes have been mobilised to lay scour protection around monopile foundations, marking the official start of offshore operations at a wind farm which aims to become the most ecological of its kind.Scour protection typically stabilizes the seabed around turbine foundations against erosion caused by currents and waves.
