Carnot MERS webinar – Presentation of GHARSA project by Frédéric Grondin

Monday 16 January à 11 h 00 12 h 00

The Carnot MERS webinars will be an opportunity to present one or several research projects on the marine engineering theme. On the program, the discovery of the objectives and the main results of the projects financed by the Carnot MERS as well as exchanges with the project leaders.

This 1st webinar will welcome Frédéric Grondin, professor at GeM to present his project on a system for monitoring the degradation of structures immersed in the sea (déGradation cHemo-mécanique des mAtériaux pleins ou cReux immergéS dans l’eAu de mer (GHARSA)).

Olivier Kermogant from LS2N will present his project to follow with accurately the evolution of biocolonization on offshore structures offshore (GOROV).

Développement d’un dispositif de mesure de la déGradation cHemo-mécanique des mAtériaux pleins ou cReux immergéS dans l’eAu de mer (GHARSA)

The objective of this project is to implement a system for monitoring the degradation of structures immersed in the sea. Whether they are made of concrete, composites, elastomers or other new innovative materials, these structures are subjected to chemical reactions in contact with sea water while being mechanically stressed. The analysis of the degradation of these materials is generally done by decoupling the phenomena: chemical test in water loaded with chloride ions, followed by a mechanical test. However, in the case of porous or hollow structures, the mechanical loading can contribute to accelerate or slow down the chemical degradation, and vice versa. Therefore, to represent the situation at sea, it is preferable to use water with characteristics close to those of the sea.
