Offshore Wind

Siemens has won two contracts valued at £516m from Statoil for the Dudgeon offshore wind farm project located on a 35km2 site, 32km off the coast of the seaside town of Cromer in North Norfolk, the UK.

Under the first contract, Siemens will be responsible for engineering, procurement, assembly and offshore commissioning of 67 wind turbine generators of 6MW each with engineering work set to begin in January 2014.

The engineering work will help develop the project’s design work for foundations and electrical infrastructure and the first batch of turbines is likely to be ready for installation by January 2017.

The service contract will see Siemens carrying out operations and maintenance of the generators for the first two years after the installation is completed, after which it will provide technicians and other agreed services to Dudgeon for three years.

Statoil renewable energy senior vice-president Siri Kindem said the supply contract will secure planned progress in the project towards full operation during 2017.

"The engineering work will help develop the project’s design work for foundations and electrical infrastructure."

"Technology development is fundamental to optimising offshore wind industry costs and solutions, and the use of new large turbines such as these is a main contributor to reducing offshore wind costs," said Kindem.

In October 2012, Statoil (70%) and Statkraft (30%) had acquired the project through the acquisition of all the shares in Dudgeon Offshore Wind, a subsidiary of Warwick Energy.

Though the project was granted the ’round two licence’ by the Crown Estate in 2003, it took until late 2012 to get all the necessary construction consents.

The Department of Energy and Climate Change (DECC) awarded a ‘provisionally affordable’ final investment decision, and consent for Dudgeon Offshore Wind farm planning variations in December 2013.

The project, execution of which is subject to final investment decision in the third quarter of 2014, will generate enough electricity to power around 400,000 households in the UK market.
