    A new UK consortium is developing a self-installing scour protection system said to be able to save an average offshore wind farm approximately GBP 8.6 million over its lifetime. The Self-Installing Scour Protection for Offshore Wind Farms (SISProtect) project is being led by Seabed Scour Control Systems (SSCS), who will carry out the design of the prototype Frond […]

    Scour – the movement of sediment that can erode the seabed around a fixed structure – is one of the major concerns when designing offshore wind turbine foundations. Indeed, turbine foundations are more susceptible to scour than predicted, as shown by Anders Wedel Nielsen, who recently joined DHI’s team in Denmark. The most common strategy […]

    Wind Farm Update

    The installation of scour protection around the 51 foundations of the Nobelwind (Bligh Bank II)offshore wind project finished yesterday, 8 June. The erosion protection consists of a light filter layer (first phase) and a heavier coating layer specifically designed for various locations and water depths. This protection will remain stable for the next 25 years, […]

    The new offshore rubber mats from ContiTech fit the contours of the seabed perfectly, and their elasticity allows them to absorb the energy of waves and vortices to prevent sand from being washed away around the foot of the turbine. These firm foundations for the piles that support them are absolutely vital. Electric power from […]

    Wind Farm Update

    In April 2013 E.ON started preparations for constructing the Amrumbank West offshore wind farm. So-called scour protection is currently being installed north-west of Helgoland. This comprises two layers of special sand bags on the seabed to prevent the sea current from washing away the sand around the foundations of the wind turbines, thus ensuring turbine […]

    In the previous article we spoke about the importance of accurate wind measurement for an optimum wind farm design. But also underwater there are elements that need to be taken into consideration when designing the foundation and cable structures for each wind turbine. Waves and currents can cause erosion of the seabed around a fixed […]

    Grid Connection

    Since the opening of the Riffgat offshore wind farm in August there was still work to be done on the connection of the wind turbines. Now the offshore wind farm is prepared for fast and smooth network connection to the grid. As soon as there is a suitable weather window, a regular sonar survey will […]
