Floating Offshore Wind turbine to be installed in Canary Islands

The first offshore wind turbine with Elisa technology is expected to be installed soon at Grand Canaria, the second most populous island of the Canary Islands. 

The President of the Canary Islands, Fernando Clavijo, visited the shipyard in the port of Arinaga, where the prototype named after a Grand Canaria engineer, Mario Luis Romero Tennent (MLRT), will be installed. 
The Elisa project requires an investment of € 20 million and is co-financed under the 7th European Research Framework Program.
The entire system foundation, tower and wind turbine - is fully pre-assembled and put into service under controlled port conditions, which reduces the risks associated with assembly work at sea.


The 5 MW Elisa prototype uses a gravity foundation, which essentially serves as a floating platform on which an automatic telescopic deployment tower with a wind turbine is anchored. Each unit consists of a platform, a mast and a turbine assembled onshore. It is then towed into the open sea to its site, using conventional tugs. Once deployed at sea, the platform is weighted and anchored to the seabed. Then, once the platform is secured, the tower is erected in its final position by means of cables and heavy-duty cable-pulling cylinders.
The installation of the generator and the blades of the wind turbines requires the use of expensive dedicated ships. The working day costs are of approximately  €300 000 and the number of vessels capable of installing wind turbines of 8 MW is limited. 
Thanks to Elisa technology, the manufacturer, ESTEYCO, estimates that costs can be reduced by 30% to 40% compared to existing conventional solutions.
Knowing the meteorological conditions of the ocean is a key element for implementing a floating offshore wind project, Open Ocean has developed the perfect tool to help your company: Metocean Analytics, the first online offer for metocean study on-demand. The Analyze tool allows you to visualize and download the operational and extreme value analysis of wind, wave, and ocean current at any chosen location.
