Context ORE systems deployed at sea are exposed to extreme waves that can jeopardize their mechanical structure. If these extreme waves are caused to break, the risk to the turbines is further increased. It is therefore essential to better understand…
The DIME project is coming to an end. Its objective was to improve the characterisation of extreme breaking sea states by coupling observations and modelling. The main results were presented during a webinar which was held on 15 October. The…
The DIMPACT project aims to better characterise the slamming forces and the effects of wave breaking on offshore floating wind turbines. It is led by Jean-François Filipot, Scientific Director of France Energies Marines. Whether it is modelling or in situ…
Download press release (PDF) Better forecasting of breaking waves to optimise the design of offshore wind turbines During storms, wind turbines are subjected to high wave amplitudes, which are taken into account in the stability calculations during the design phase.…
The DIME project on breaking waves is coming to an end. Before the results webinar on 15 October 2021, we take a look at the project with Rui Duarte, research engineer in site characterisation tools and methods. What is your…
Four new research and innovation projects
Offshore Wind - France Energies Marines launches four new research and innovation projects to support the acceleration of the sector On July 10, the Board of Directors of France Energies Marines approved the launch, in the fall of 2024, of…
Context For offshore renewable energies to be effectively integrated into the French energy mix, it is essential that they increase their competitiveness in the short and medium term. Under- and over-dimensioning of energy converters and their peripheral components, respectively, lead…
The DIME collaborative project, which focuses on improving knowledge of sea states in the event of storms, includes an unprecedented operation that began in December 2017 near the island of Ushant. The principle? To use La Jument lighthouse as an…
Wave observation and modelling for ORE development The most accurate knowledge of sea states is crucial in terms of input data for the definition and optimal design of ORE projects. These properties are used throughout the life cycle of a…
Motivation & background The quantification of cumulative impacts between offshore wind farms (OWF) development and fisheries relies on numerical models based on schematic representation of fisheries dynamics. A critical limitation lies in the simplicity of this representation which do not…
Sheets summarising the results of our collaborative R&D project At the end of each of the collaborative projects that we carry out, we prepare a fact sheet that includes the context, objectives, main achievements, output resources and a short conclusion…
Floating offshore wind sector: a market with promising development Floating offshore wind technology makes it possible to envisage the deployment of offshore systems in areas inaccessible to bottom-fixed wind turbines due to water depth of more than 60 m. Its…
A structuring document France Energies Marines' scientific and technical roadmap is a document that has structured the Institute's R&D activities since its creation. It guides us in our project development. Each of the four programmes is dealt with in terms…
Climate change impact on offshore wind
Taking climate change into account Over the lifespan of offshore wind farms which is more than 25 years, the wind resource, or in other words the wind distribution, might evolve leading to a modification of the associated energy production. The…
Precise knowledge of winds: a necessity for the ORE development The definition and optimal design of ORE projects requires an accurate knowledge of atmospheric flow properties such as the spatial and temporal variability of wind at turbine mast height, its…

An institute well-equipped to support the OFFSHORE WIND sector A multidisciplinary team of 100 employees, four R&D themes, a model of public-private collaboration shared with seven other institutes for energy transition and eight technological research institutes: this is France Energies…
Heavily urbanised coastal areas are increasingly exposed to the risk of extreme events such as storms. Improving knowledge of these phenomena in order to better predict their impacts is the objective of the MARLIT project coordinated by the AZTI Foundation…
A wide variety of concepts at the prototype stage Wave energy converters are systems for recovering the energy generated by the waves and transported by the swell to return it, usually in the form of electricity. Four types of installation…
FEM Tribune – ORE integration webinar
A 4-webinar series has been proposed in autumn 2020 in the framework of the Tribune de France Energies Marines. Organised this year around the theme of the integration and optimisation of ORE farmss, this event aims to discuss about R&D…
Le développement des EMR soulève un certain nombre d’interrogations souvent liées aux impacts environnementaux de ces nouvelles manières de produire de l’énergie. Les questions répertoriées sur cette page ont été traitées par des groupes d’experts scientifiques. Les réponses apportées ont…
Use of tidal currents: resources vs. constraints of tidal sites The potential of kinetic energy from tidal currents is subject to strong spatial and temporal variations. Although now mature enough to consider development on a commercial scale, tidal technology is…
Mature technology, but challenges for increased performance Bottom-fixed offshore wind technologyis emerging in Northern Europe as one of the main sources of renewable energy. At sea, as winds are more stable and often of higher average speed, offshore wind farms…
