Towing tank


Overview


The towing tank at Centrale Nantes is 140 m-long, 5 m-wide, with a constant depth of 3 m. It is equipped with a towing carriage able to go both ways, at speeds up to 8 m/s. At one end of the tank, a wave maker allows generating waves with wave heights up to 0.5 m. At the other end, a beach allows waves to break, therefore limiting the reflection of waves in the tank.

Dimensions :

140m x 3m x 5m

Carriage :

The carriage has a maximum speed of 8 m/s and runs over the total length of the basin.

Preparation area :

A large preparation area (10 x 10m) is dedicated to the assembly and the preparation of the tests.

Overhead crane :

The overhead crane covers the central area of the towing tank, as well as the preparation area. It features a 2.5 tons hoist. The maximum clearance is 6.50m from the ground

Divers :

A team of two qualified IB category divers is available to operate in the towing tank.

Main features


Waves :

The tank is equipped with an hydraulic flap-type wavemaker (unidirectional waves only). Opposite the wave generator, a passive wave absorber is installed.
