Spanish wind group Gamesa said it has secured type certification for its first offshore turbine from DNV-GL.
Certification for the G128-5.0 MW marks “an endorsement for the platform's technology that in turn bolsters the marketing and industrialisation processes”, Gamesa said.
The prototype turbine – which was also Spain’s first offshore machine – has been operating on the island of Gran Canaria since July 2013.
Since then it has pumped more than 6GWh into the grid and broken a national record for daily production, Gamesa added.
The company said: “Over 1.3 million engineering hours went into designing and validating the patented technology fitted into the offshore turbine in more than 100 accredited laboratories and testing centres in the US, Asia and Europe.
“The turbine's various parts were subjected to over 618 tests, including around 100 functional trials in the field.”
Since installing the turbine the manufacturer has announced plans to form an offshore joint venture with France’s Areva, with the G128-5.0 MW due to go into the mix as part of Gamesa’s contribution.
