In April 2009, offshore work started on the Rødsand 2 wind farm, in the south of Denmark. A concrete gravity-based foundation is to be used. A new method for the preparation of gravel beds has been developed. The seabed has been prepared by removing the soft top sediment and the square screeding frame is then placed in the pit (Figure 4). Gravel stone is placed inside the frame, and the hydraulic levelling of the gravel bed and all other operations are then carried out through remote control by staff in a follower vessel.
