Offshore Wind

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


Customer: CNIM

Context: CNIM is developing an innovative ship for wind farm’s maintenance in the North Sea.

Challenge: In order to conceive a ship working in harsh conditions specific to the North Sea CNIM needs to know historical metocean conditions at differents geographical locations in the North Sea.

Solution: Open Ocean provided CNIM with an access to the Metocean Analytics solution. Thanks to this online solution, CNIM obtained directly all the wind, wave and ocean current datas as well as the statistics necessary to identify  sea conditions at different wind farms located in the North Sea.





Customer: DCNS Energies 

Context: DCNS Energies is involved in numerous marine renewable energy technology and project developments especially in the tidal, ocean thermal energy conversion, and floating offshore wind sectors.

Challenge: Considering the geographical market widespread for these technologies, DCNS Energies needs to identify and characterize offshore sites of interest around the world with respect to the historical metocean conditions.

Solution:  Open Ocean has provided DCNS Energies with an unlimited access to the Metocean Analytics solution. With Metocean Analytics, DCNS Energies obtains directly online all the wind, wave, ocean current, and sea temperature data and statistics required to qualify potential offshore sites of interest for development.




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: RES Offshore

Context:  RES-Offshore offers integrated development, engineering, construction and AO&M services for utility-scale renewable energy projects. 

Challenge: RES Offshore needed a long wave time series for a location offshore northern Scotland.

Solution: Open Ocean provided them with the main wave parameters from a proprietary wave numerical simulation covering the whole northern Scotland.



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.
