Offshore Wind

Open Ocean’s expertise has been recognized for its strong added value in the decision process for Offshore wind project management




Customer: RTE 

Context: RTE, the French electricity transmission system operator is in charge of the high voltage grid installation, connection and management onshore and offshore. This includes the connecting of all the marine renewable energy farms being developed in France.

Challenge: With the growth of marine renewable energy developments in France with numerous offshore wind and floating offshore wind farms, RTE needs several metocean studies along the cable routes to plan and design the installation in the best possible manner. Because of the numerous needs, RTE decided to set up a framework contract.

Solution: Open Ocean in collaboration with ACRI-HE has been awarded this framework contract to provide metocean studies to RTE when required for subsea cable installation.




Customer: Eoliennes en mer

Context: Eoliennes en mer is a joint venture between ENGIE, EDPR and Neoen Marine created for the development of the offshore wind farms offshore Dieppe-Le Tréport and offshore Yeu and Noirmoutier Islands.

Challenge: Eoliennes en mer requires metocean data and parameters for the farm development, the infrastructure design and the operations planning.

Solution:  Open Ocean provided Eoliennes en mer with an access to Metocean Analytics, the first online offer for metocean study on-demand. Metocean Analytics allows Eoliennes en mer to obtain easily and promptly metocean data and statistics at the exact locations of interest for the two farms located on different shores of the French coast.


Customer : RTE

Context:  RTE is in charge of the French offshore wind farms connection to the coast and to the national grid.

Challenge : RTE needed to take decisions regarding the most relevant cables    route with respect to the oceanic and sedimentary constraints. RTE needed to  consider the cables installation method with the required burial depth in oder to deal  with the agitation due to currents and waves.

Solution : In collaboration with Egis, Open Ocean  provided RTE with a complete        analysis of ocean currents and waves along the potential cable routes for the wind      farm projects offshore Saint Brieuc and Saint Nazaire. Based on existing metocean  database, tailored modeling, and statistical analysis, Open Ocean computed extreme  wave values, storm surge analysis, as well as bottom current estimate at numerous  locations from the offshore wind farm to the coast.
