Peter Madsen Rederi A/S has completed work on Amrumbank West Offshore Wind Farm in the North Sea. The Danish company has laid 45,000 sand bags around wind turbine foundations to prevent scour forming which would destabilise the foundation. The bags were filled with 60,000 tons of dredged sand, which were laid in a period of […]

Ridgeway Renewables have successfully supplied the first “Kyowa Filter Units” from Japanese manufacturer Sumisho Kyowa Limited for offshore wind turbine monopile scour protection in Europe. Using a combination of the 4 & 8 tonne type units filled with specific aggregate in a circular formation around the monopile, engineers were able to achieve tough design criteria […]

29 May 2013 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 […]

23 April 2013 Environment

Specialist sea bed protection work is being undertaken on the Teesside offshore wind farm that could help to increase the marine biodiversity of the area. EDF Energy Renewables has appointed Marske Site Services (MSS) of Stokesley, near Middlesbrough, to carry out the ‘scour protection’ of the steel monopile foundations sunk up to 30 metres into […]

12 February 2013 R&D

In the framework of the Marinet program, IMDC, in a partnership with HR Wallingford, University of Ghent and the Faculty of Engineering of the University of Porto, finalised the physical model tests at the University of Aalborg (DK) at the end of December 2012. The test program was set-up to investigate an innovative scour protection […]

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 […]

30 March 2015

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 […]

7 August 2012 Operations & Maintenance

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 […]

13 February 2019 Contracts & Tenders, Operations & Maintenance

Pipeshield International Limited has secured a contract by DeepOcean to supply the scour protection for the East Anglia One offshore wind farm in the UK. According to the Lowestoft-based company, more than 300 bespoke fronded concrete mattresses (FCMs) have been manufactured at the port of Great Yarmouth within close proximity of the deep water berth. Pipeshield […]

8 June 2018 R&D
