EMDT modifies site investigation schedule

In: Windfarms
Eoliennes en Mer Dieppe Le Tréport (EMDT) is commencing a geophysical survey at the French Dieppe-Le Tréport offshore wind farm, but has postponed the UXO campaign following objections from fishery organisations.

The geophysical campaign concerns an area around the future foundations, the electrical substation and along the cable route to better understand the nature of the seabed. It will also involve mapping the seabed, using a multibeam sounder, and collecting three-dimensional images of the sea depths using a lateral sonar.

A short geotechnical campaign will run alongside, with the aim of researching bacteriological corrosion. It will involve carrying out 5 vibrocarotings and a sampling approximately 500 litres of seawater. Surface sediment will be studied in the laboratory and will provide useful data to improve knowledge of the corrosion rate of future foundations.

Noordhoek Pathfinder, a vessel from Noordhoek Survey BV, arrived in Le Treport on 20th July. The survey is expected to take approximately one month.

Earlier this month, a letter signed by elected officials and associations was sent to French President Emmanuel Macron, requesting cancellation of the wind farm. In the letter, the signatories explain how fishermen of Le Tréport and neighboring ports have continuously expressed their opposition for the project. The area is rich in shellfish and fish and the signatories consider that project would impact fishing, tourism and trade. The letter also requested cancellation of project site investigations scheduled for this summer, stating that they would cause further disruption to the fishing industry, which has already seen impacts from storms and COVID-19 in 2020.

Taking comments of the Regional Committees for Maritime Fisheries and Marine Fish Farms in Normandy and Hauts-de-France on board, EMDT has decided to postpone a UXO survey initially due to take place August-September. The planned identification and neutralization campaign was scheduled to identify possible explosive devices from the Second World War.

The 496 MW
Dieppe-Le Tréport wind farm will be located 17 km from Dieppe and 15.5 km from Le Tréport, with a seabed depth ranging from 14 to 24 metres.

EMDT represents a consortium of ENGIE (31%), EDP Renewables (29.5%), Sumitomo Corporation (29.5%) and Banque des Territoires (10%). EMDT acquired the administrative authorizations necessary for the construction of the wind farm in February 2019. Commissioning of the project, which will feature 62
Siemens Gamesa 8.0-167 DD wind turbines, is scheduled for 2023, subject to the appraisal of appeals against it.
