Hydrodynamic and ocean engineering tank

Measuring 50 m long by 30 m wide by 5 m deep, this Centrale Nantes tank is equipped with a segmented wavemaker composed of 48 hinged flaps to generate directional waves. A wind generator producing an airflow of 3m by 3m with speeds up to 15m / s can be positioned over the tank.

This tank is used for small scale physical simulation of floating, sailing or moored offshore structures (i.e. ships, MRE systems or oil rigs).

Due to its size and generation capacity, it is currently the largest tank in France for this type of study.
