Navantia Seanergies and Windar Renovables have started production of the first of the 14 XXL monopiles for the  
Moray West project, with the bending of the first sheet. Over the next few months, the Fene shipyard will simultaneously build XXL monopiles and jackets for Ocean Winds.

The monopiles will have an approximate length of 90 metres, a maximum diameter of 10 metres and a maximum weight of 2,000 tons. This type of XXL piles, the product with the highest market share among fixed foundations, is new to Navantia-Windar's offer.


The global execution period is 10 months, generating 280,000 working hours and an average of 150 direct jobs per month for the manufacture of the 14 XXL monopiles.


The Moray West offshore wind farm is being developed by Ocean Winds, a joint venture between EDP Renewables and ENGIE.  A small minority stake is held by UAB Ignitis Renewables. The project was awarded a 15 year CfD for the delivery of 294 MW wind generation at £37.35/MWh (in 2012 prices). It is located on the East coast of Scotland in the Moray Firth, approximately 22.5 km from the Caithness coastline and covers an area of covers 225 km2. It will be comprised of 60 wind turbine generators with an installed capacity of 882 MW. The wind farm is expected to make a final investment decision and reach financial close in the coming months while ramping up construction activity to meet planned first power in 2024.

In addition to Moray West, Ocean Winds awarded Navantia-Windar work for construction of 62 jackets for its
Dieppe le Tréport offshore wind farm, north of France. It will be completed in Fene (A Coruña) in the first quarter of 2023 with an approximate duration of two years and four million working hours. Therefore, for a few months the production of two types of foundations will take place for the same client.
