Offshore wind environmental monitoring and impact studies are an important component of the research conducted at the SEM-REV offshore test site. The PIAFF&CO project will improve knowledge of flying fauna - birds and bats - in the vicinity of offshore wind farms. The project is run by Centrale Nantes in conjunction with the Centre d'Écologie et des Sciences de la Conservation du Muséum national d'Histoire naturelle, the St Nazaire offshore wind farm and BW Ideol.

The SEM-REV offshore test site is tasked with meeting the R&D challenges of Marine Renewable Energy technologies. To this end, measurements have been made on the offshore site since 2009. SEM-REV has just published a report summarising the meteorological and oceanic data from the site, located off the coast of Le Croisic.

With 295 applications received, 170 projects selected and the funding of more than 600 weeks of access to the MaRINET2 consortium's test facilities, the outcomes of the MaRINET2 Transnational Access program are extremely positive. This transnational program is a major component of the MaRINET2 project (H2020-INFRAIA, 2017-2021) aimed at accelerating the development and deployment of Marine Renewable Energy (MRE) technologies.

Work began offshore ten years ago on installing the export cable, thereby making SEM-REV - Centrale Nantes' offshore test site - a reality. Since then the site has certainly lived up to its initial promise.

Centrale Nantes has a new postdoctoral position available within the framework of the EU H2020 FLOATECH project. The overall objective of this project is to increase the technical maturity and the cost competitiveness of floating offshore wind energy. Among the different specific objectives, readiness of a real-time prediction of the wave field from a set of measurements and feeding the wind turbine controller is thought to be improved. Find here the complete offer and the application procedure.

Enedis has already connected more than 536,000 renewable energy installations in the Pays de la Loire region and is committed to playing an active role in renewable energy development across France. The power grid operator has thus responded positively to the requested increase in power capacity on Centrale Nantes' offshore test site, SEM-REV.

Maritime transport is currently experiencing rapid growth and it is also the most efficient form of transport in terms of GHG emissions (gCO2/Tonne/km). Centrale Nantes, via the LHEEA, and MAN Energy Solutions have been working together on this subject since 2018, as part of an industrial chair on the gradual decarbonisation of marine propulsion and electricity production. Read on for an update on this chair.

A long-term working relationship between Mann+Hummel and Centrale Nantes, via the LHEEA, began over 13 years ago with several collaborative projects. These joint research activities led to the creation of two chairs led by David Chalet. The first between 2014 and 2018 was on "Innovative intake manifolds and thermal management". A new chair is underway, until 2023, on a different topic: "Filtration systems: fluid dynamics and reduced energy consumption". Read on for an update on this chair!

One of the major challenges in the maritime field today is to take extreme sea conditions into account when designing marine structures. The WASANO project, which brings together 10 international universities and 3 companies, is addressing these issues through several disciplines. Read on to learn more about the first series of tests carried out in March in the Centrale Nantes towing tank.

On 24 March 2022, a first-ever evacuation exercise by helicopter from a floating wind turbine (FLOATGEN) took place on the SEM-REV offshore test site in France. This exercise in real conditions required cooperation between CROSS Etel, the Sécurité Civile, the SNSM, BW Ideol and Centrale Nantes.

Rogue waves are very high ocean waves, compared to their immediate neighbours, which can form on both calm and rough seas. This sudden and unpredictable phenomenon may be rare, but it needs to be studied because of its danger to sea users. These rogue waves are the subject of joint collaboration between researchers from Centrale Nantes - via the LHEEA - the CNRS and the universities of Paris and Lille as part of the ANR DYSTURB project.

Jeroen Wackers, a research engineer in the METHRIC team, works on the simulation of maritime flows using the automatic mesh refinement method.
