Energy and marine consultancy ABL France has announced the successful completion of a crucial marine technical study for French tidal energy developers Normandie Hydroliennes (NH) and Hydroquest. The study is aimed at supporting the safe development of the NH1 and FloWat tidal turbine pilot projects, strategically located off the coast of Normandy, France.
The NH1 and FloWat tidal turbines, slated for installation in proximity to the Raz Blanchard ferry route, known as one of the most powerful tidal sites globally, presented a unique challenge. To mitigate potential risks and ensure the safety of marine traffic, an exclusion zone was deemed necessary and had to be defined and communicated to local authorities.

Normandie Hydroliennes (NH) and Hydroquest engaged the expertise of ABL's team in France to conduct a comprehensive technical study. The primary objective was to provide substantiated justification for the required vessel exclusion zone at the project site.
ABL's study focused on determining the drifting speed and direction of a relevant vessel type under diverse weather conditions. The data generated was meticulously analyzed in conjunction with the distance between the ferry route and the tidal turbine farms to precisely delineate the exclusion zone.
Leveraging ABL's extensive marine operational experience, the study took into account various factors, including the captain's reaction time, the number of motors on ferries, vessel draft, and other criteria crucial in minimizing the risk of contact between the vessel and the tidal turbines.
