Miros’ dry-mounted Wavex has been selected by EQUANS to collect operation-critical wave and current data on the offshore substation for Iberdrola's
Saint-Brieuc offshore wind farm off the coast of France.

Wavex is a virtual sensor designed for wave and current measurements, capturing and processing sea surface backscatter data via a standard X-band marine navigation radar. Through adaptive algorithms, it calculates and displays directional wave and surface current data. According to Miros, the contributes to increased vessel operability, improved safety, and cost savings.

As the Saint-Brieuc maintenance strategy relies on using surface vessels, jack-up vessels, and ROVs/UAVs maneuvering close to the foundations and cables, the maintenance work would typically be limited by current speeds as low as 1m/s. Since the site current speed exceeds 1m/s daily, Iberdrola needs to manage the working time of the vessels concerning the specific operational characteristics of those vessels.

Emilie Dorgeville, VP Business Development Renewables & Ports at Miros AS, said: “This is an ideal project where our dry-mounted, IoT-enabled Wavex sensor will deliver at its best and showcase what it is good for - accurate, reliable ocean-monitoring, measuring local sea state conditions and making the data accessible in real-time to all stakeholders both onshore and offshore.”

Alain Goddyn, Section Manager Department Water Section Marine at EQUANS, commented: “The Wavex sensor is an addition to the meteorological system which is developed by our section and to be deployed on the Saint Brieuc substation for the measurement of the local meteorological conditions.”

Iberdrola is working together with EQUANS, which is responsible for the integration work on the substation locally in Belgium, before transporting it to the site on the North Coast of France.  

The 496 MW
Saint-Brieuc wind farm, 16 km off the French coast, will feature 62 Siemens Gamesa SG 8.0-167 DD turbines, standing at 207 metres high. It is being developed by Ailes Marines, subsidiary of Spanish energy giant Iberdrola. Covering an area of 75km2 the project will be the first large-scale offshore wind farm in Brittany and, when operational it will be capable of generating 1,820 GWh/year of electricity, expected to meet the demands of  835,000 people.
