Teesside based Offshore Structures (Britain) Limited (OSB) will play a significant role in the production of foundations for one of the world's biggest offshore wind farms.


DONG Energy today (14 September 2015) named Germany's EEW SPC (EEW) as main contractor for the supply of foundations for its 660 megawatt (MW) Walney Extension offshore wind farm off the Cumbrian coast.


The contract covers the supply of 87 foundations for which the monopile structures will be manufactured by EEW in Rostock. The associated transition pieces will be produced under sub-contract, with OSB producing 40 in their Teesside factory, while Bladt Industries produce the remainder in Aalborg, Denmark.


Mats Vikholm, Senior Vice President for DONG Energy Wind Power, said:


"This contract award is the direct result of close cooperation between DONG Energy Wind Power and EEW aimed at reducing the cost of electricity from offshore wind generation.


"This cooperation began on the Burbo Bank Extension offshore wind farm for which EEW was awarded the foundation manufacturing contract in February this year. It is especially pleasing that we have again been able to secure UK content through the involvement of OSB who have already manufactured parts for the first transition piece structures for the Burbo Bank Extension project."


Earlier this year DONG Energy chose MHI Vestas Offshore Wind, with their 8.0MW turbine, as its preferred supplier for the first phase of the Walney Extension offshore wind farm. It also named Siemens as preferred supplier for delivery of their 7.0MW wind turbine for the second phase of the project.


Walney Extension has already been awarded a contract for difference under the EMR FID-enabling regime and, in November 2014, the project was granted consent by the British Secretary of State for Energy and Climate Change. DONG Energy has not yet taken a final investment decision on the project.


The Walney Extension offshore wind farm has a maximum capacity of 660MW and is located approximately 19 kilometres off the Cumbrian coast, next to the 367.2MW Walney offshore wind farm. Based on the formal permits and timetable for Walney Extension, offshore construction could potentially start in 2017.
