V164-7.0 MW turbine launched

by Vestas Wind Systems A/S April 5th, 2011

Lowering the cost of energy in relation to offshore wind is essential for the industry. Some of the major stepping stones in achieving this are size and subsequent increased energy capture, which means a need for much bigger turbines that are specifically designed for the challenging offshore environment.

With the introduction of the V164-7.0 MW Vestas is taking a major step towards meeting these needs.

CEO Ditlev Engel says of the new turbine: “We are very pleased to be able to serve the market and show our commitment to the offshore wind industry by introducing our dedicated offshore turbine - the V164-7.0 MW. Seeing the positive indications from governments worldwide, and especially from the UK, to increase the utilisation of wind energy is indeed very promising. We look forward to this new turbine doing its part in making these political targets a reality.”

According to Anders Søe-Jensen, President of Vestas Offshore, the offshore wind market is set to really take off over the coming years, but more so in some parts of the world than in others: “We expect the major part of offshore wind development to happen in the Northern part of Europe, where the conditions at sea are particularly rough. Based on our broad true offshore experience and our many years as pioneers within the offshore wind industry, we have specifically designed the V164-7.0 MW to provide the highest energy capture and the highest reliability in this rough and challenging environment. This makes our new turbine an obvious and ideal choice for instance for many UK Round 3 projects.”

Combining innovation and proven technology to ensure reliability

The innovative part of the new turbine is, along with a wide range of technical features, its size and consequently much increased energy capture whereas the proven technology is represented by, among other things, the medium-speed drive-train solution.

“We actually kept all options open from the start, running two separate parallel R&D development tracks; One focusing on direct drive and one on a geared solution. It soon became clear that if we wanted to meet the customers’ expectations about lowest possible cost of energy and high business case certainty we needed a perfect combination of innovation and proven technology and so the choice could only be to go for a medium-speed drive-train solution,” says Finn Strøm Madsen, President of Vestas Technology R&D on this particular design choice and concludes: “Offshore wind customers do not want new and untested solutions. They want reliability and business case certainty – and that is what the V164-7.0 MW gives them.”

To ensure alignment between customer needs and the features of the next generation offshore turbine, a number of experienced offshore customers have been invited to provide their input during the development process – resulting in a match between turbine specifics and customer business cases.
