The offshore wind energy industry is developing rapidly in its drive to decrease construction and maintenance costs to produce electricity from a renewable energy source at the cheapest possible price.

There’s on-going technological advancement to produce turbines that can generate more electricity as each offshore wind turbine is expensive to install.

Vestas Wind Systems A/S has raised the game by producing the first prototype 80 metre blade for an 8.0 MW wind turbine, which will be the world’s most powerful offshore wind turbine, at Vestas’s research and development centre at Newport on the Isle of Wight in the UK.

The wind turbine blade will undergo an extensive testing regime to ensure total reliability.

The 80 metre blade is the longest ever produced by Vestas Wind Systems.  It uses the structural shell design, a proven concept in which the loads of the blade are carried in the shell, rather than using a spar at the centre of the blade.

The swept area of the rotor will be 21,124 square metres, which is larger than the London Eye.

In order to validate the strength and reliability of the wind turbine blade it will be tested to its limits for six months, reproducing the challenging wind conditions of the North Sea over a simulated 25 year lifetime.

Anders Vedel, Chief Technology Officer, said that the tests will provide certainty to customers looking to make large investments in offshore wind.

“Test and verification of the blade is a critical stage of the development of the V164-8.0 MW wind turbine,” he said.

“Moving as much of the verification process as possible into our state of the art test centre ensures the blade, the bearing and other components perform to the high standards our customers expect,” Mr Vedel said.

The V164-8.0 MW prototype will be installed in the first quarter of 2014 at the Danish national testing centre in Østerild.

Vestas has delivered about 49,000 wind turbines in 73 countries amounting to 56 GW of cumulative capacity worldwide.

Their working wind turbines currently reduce carbon emissions by over 60 million tons of carbon dioxide every year.
