New opportunities in a market of tomorrow: offshore wind power

FuturENERGY September-October 2020

Since Navantia signed its first offshore wind power contract with Iberdrola in 2014, the sector has represented a new horizon of opportunities for this military shipyard, bringing diversification and growth, both in jobs and in the GDP of the Spanish economy. The experience of Navantia in the oil & gas sector allows them to maintain a varied offshore wind power portfolio, including jacket-type fixed assemblies, floating structures and offshore substations. Its two facilities, one in NE Spain, the Fene shipyard and the other in the south, the Puerto Real shipyard, fitted out to undertake this activity in record time, are currently ranked among the best equipped and most extensive in Europe.

Navantia has specialised in building these supports for offshore wind. These 60-metre structures or more have to withstand the water for a minimum of 25 years, subjected to the adverse conditions of erosion and currents. They must also withstand possible collisions with vessels, preventing the turbine from falling, while allowing the structure to bend to minimise damage to the impacted vessel. Similarly, within its wind power department, the company manufactures offshore electrical substations that are installed in open waters, to receiving energy from the turbines for its subsequent transformation and sending to land for consumption.

Navantia’s debut in offshore wind is thanks to Iberdrola, entrusting them with the manufacture of jackets and electrical substations for the Wikinger, East Anglia One and Saint-Brieuc wind farms, where the latter is the latest contract to be signed by the company in the offshore wind sector and its largest in this segment.
