Nantes Wide Tank

The wide tank at Ecole Centrale de Nante was Edinburgh Designs' first wave machine capable of generating a continuous 1m sine wave. The 48 paddle machine is heavily used by the wave power community for wave power device survivability testing.  Installed in 2001, this tank is still in operation having never been drained.

A comprehensive refit in 2022 involved replacing all electrical cabinets, motors, bearings and force transducers.
The tank is now operating to modern standards and is ready to run for another 20 years.
