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. The aerodynamic loading is performed by a state of the art Software In the Loop system, with real time execution of OpenFAST modules.

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.
