Gamesa's 5 MW offshore turbine obtains design certification

Gamesa has begun installation of its first G128-5.0 MW offshore prototype on the Arinaga Quay on the island of Gran Canaria (Canary Islands, Spain), and expects to start commissioning in the second quarter of 2013.

In a written statement, the company said it hopes to secure certification in early 2014.

Gamesa has previously said it will concentrate its resources in coming years on developing two new turbine systems, with nominal capacity of 2.5 MW and 5.5 MW (the latter suitable for both onshore and offshore use), beginning in the second quarter of 2014 and the fourth quarter of 2014, respectively.

The company is determined to play an active role in the offshore wind energy industry, tailoring its technological and manufacturing investments to market performance.

In addition to its 5.5 MW offshore system, the company foresees higher-capacity offshore turbines (7 MW-8 MW) in the medium to long term.

The Gamesa 128-5.0 MW offshore machine is equipped with proven and validated technology already integrated in Gamesa's 4.5 MW turbine and benefits from the know-how and experience gained from the latter system's roll-out.

"Starting with a proven, validated and certified technology is an indisputable competitive advantage," said Gamesa Managing Director of Commercial, Projects and Offshore Javier Perea. "We had already come a long way. Nonetheless, the variable and extreme conditions offshore wind turbines are exposed to, combined with often difficult-to-access sites, have prompted us to work on turbines like the G128-5.0 MW, which are able to minimise shut-downs, reduce maintenance tasks and achieve competitive cost of energy and optimal returns throughout a wind farm's entire life cycle."
