Final turbine stands at Dudgeon

Posted by 4C Offshore on


The final Siemens SWT-6.0-154 turbine has been installed at the Dudgeon offshore wind farm off the coast of Cromer, UK. The first turbine was installed at the site in early January and work was carried out by A2SEA's SEA CHALLENGER.

According to project developer Statoil, the project was completed to the agreed time and below the £1.5bn budget that was set when the final investment decision was made in 2014.

Ever since the first turbine produced electricity at the beginning of February 2017, all the turbines have joined the production, one by one.

“Dudgeon offshore wind farm is part of Statoil’s strategy of gradually supplementing our oil and gas portfolio with profitable renewable energy. Offshore wind has been a natural place to start, as we can build on our maritime expertise, experience from complex projects and our supplier chain. With Dudgeon in full production Statoil is well on its way to providing more than one million households in Europe with renewable electricity,”
says Irene Rummelhoff, executive vice president for New Energy Solutions in Statoil.

The SEA CHALLENGER operated from Alexandra Dock in the Port of Hull, home to Siemens new manufacturing and pre-assembly facility. This is the first time, the Port of Hull has been used as load out port for an offshore wind project.

Each of the 67 turbines consisted of 90m towers, 75m blades as well as nacelles. They were mounted onto monopile foundations which were installed by Seaway Heavy Lift's vessel Oleg Strashnov last year.

The project is located 32km off the coast of Norfolk, UK and is 20km east of the Sheringham Shoal, another project Statoil owns stake in. Dudgeon's turbines have a combined capacity of 402MW which is expected to produce 1.73 TWh/year meeting the demands of  400,000 UK households.

Operations and maintenance work at the site are being carried out by the newly built ESVAGT Njord which began operations after its christening in September last year. It will operate from the purpose-built base in Great Yarmouth which also acts as a control centre for the project.

Further to Dudgeon,  Statoil is also currently developing other offshore wind farms. These include the Hywind Scotland pilot park offshore Peterhead, Scotland, the world’s first floating wind farm, will come in production in late 2017. Furthermore, the company acquired 50% of the Arkona offshore wind farm in Germany, which will come in production in 2019. Statoil was also declared the provisional winner of the U.S. government’s wind lease sale offshore New York at the end of 2016.
