15,000-Tonne Wind Farm Installed onto Seabed off Blyth Coast

It’s a world first for the North-East as a float and submerge Gravity-Based Foundation (GBF) has been successfully lowered onto the sea bed as part of the Blyth Offshore Demonstrator wind farm. This pioneering project acts as a flagship for EDF Energy Renewables as it’s the first time that this method has been utilised for wind turbine installation.

Once operational, the new wind farm will see the development of five turbines capable of generating 41.5 MW; this is enough power to cater for around 34,000 homes saving a total of 57,600 tonnes of CO2 emissions each year. As a significant project milestone, one of the GBF’s – constructed by Royal BAM – has been submerged four miles offshore past the Herd Groyne Lighthouse off the coast of Blyth and will provide the support for the wind turbines.

Before the delivery and installation of the turbines, the civil engineering firm Strukton will be pumping sea water from the North Sea into the foundations using a specialist vessel. The contractor VBMS will then lay specialist 66kV inter array and export cables down, connecting the wind farm to a new substation currently under construction in Blyth.

We are very pleased to see the progress so far that has been made on this ground breaking project and the contribution it is making towards helping the UK to meet its targets of a low carbon, sustainable future.
