DIME Webinar

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…

DIME

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…

In-situ waves observation

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.…

At La Jument lighthouse

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…

Floating offshore wind

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…

COASTWAVE

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…

Wave energy

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…

Waves

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…

The Institute

An institute well-equipped to support the ORE sector A multidisciplinary team of 46 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 Marines…

Tidal currents

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…

Bottom-fixed offshore wind

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…

Can fixed-foundation wind farms alter the sea state to the extent of creating rogue waves?

Sea state changes within a fixed-foundation wind farm could be due to the diffraction phenomenon and the modulational instability caused by the turbine network. A rogue wave is a short wave with a severe combination of height and steepness. Rogue…
