They included Alstom, Elsevier, Engie, Cerema, Marinet, Embassy of Canada, IEA-OES Annex IV, EDF, INORE.

Two exhibitions dedicated to the MREs in the “Cité des Congrès”

The large hall of the convention center and the mezzanine level gave us the opportunity to organize two distinct exhibitions:


A pedagogical exhibition on Marine Renewables accessible to the general public. Installed by the staff (PhD – researchers – technicians) of the academic Lab LHEEA at ECN, using models from their experimental facilities and posters especially designed to explain the matters to visiting school classes and non expert visitors.



A professional exhibition reserved for EWTEC partners, industry or institutions, keen on presenting their skills, new products or technical offer to the participants. It was located in the hearth of the Conference venue.

Fourteen  boothes were occupied , from Monday to Thursday noon, and visited by the participants during the breaks or between the sessions.

EWTEC 2015 Social events

EWTEC2015-the banquet in the cage of the Big Elephant

The banquet, supported by ALSTOM, was held in the hall of a former shipyard transformed into a factory where strange mechanical animals, like this big elephant, are assembled just for people to enjoy. It helps to maintain the tradition of marine building excellence in Nantes. Indeed good french food and wines, as expected here, and jazz music by the splendid Nantes University Big Band : SWINGOCAMPUS.

EWTEC2015-ECN wave basin

Visit at ECN facilities: On Thursday afternoon, two groups of EWTEC participants were admitted to visit the LHEEA Lab facilities at ECN, where demonstrations of waves were performed in the large 30m x 50m Ocean multidirectional waves basin. Wave energy converters are routinely tested there, together with floating offshore wind turbines thanks to our facilities able to reproduce natural wind blowing above sea waves.

Post Conference tour: Tidal Barage “La Rance” and  “Mont Saint Michel”

MSM 187-15


Starting on Thursday afternoon and ending on Friday at 15:00, a short tour was organized to visit one of the Mont Saint Michel, in northern Britany.

La Rance: EDF 240MW tidal plant

On Friday morning, the twenty EWTEC participants were admitted to visit the 240 MW electrical plant of the “La Rance” barrage, the oldest (1966) and most powerful connected tidal plant in Europe. During a one hour meeting within the plant, the Director and engineers of the technical staff kindly answered EWTEC visitors questions related to operating such a unique and atypical plant.


First to all our partners and sponsors, listed here.

To the EWTEC Technical Committee, and to all the reviewers for their thorough peer reviews which permitted to maintain this high scientific quality of the selected papers despite the increase of the number of submitted abstract for this 2015 issue.

And, last but not least, to the team of volunteers, all students or staff of the LHEEA Research Dept. at ECN, who did really a great job and who made this 2015 EWTEC a great success.


the happy EWTEC 2015 volunteers. See you soon back in Nantes !!
