The Ship Hydromechanics Test facilities include three elements:
1. The large towing tank.
With dimensions: L = 142 m.; B = 4,25 m.; D = 2,5 m. The towing carriage is completely computer controlled and capable of speeds up to 8,0 m/s. The basin is equipped with a hydraulically activated wave generator of the hinged flap type, capable of generating both regular and irregular waves, ranging from 0,75 to 10,00 m. length and with a maximum height of 0,25 m. Extensive equipment forms part of the facility, including 6 D.O.F. oscillators and measurement equipment.
2. The small towing tank.
With dimensions: L = 75 m.; B = 2,5 m.; D = 1,2 m. The towing carriage is capable of speeds up to 3,0 m/s. The basin is equipped with a hydraulically activated wave generator of the hinged flap type, with adjustable rate of rotation versus translation, so capable of simulating shallow water conditions. Wave generator range is capable of generating regular and irregular waves, ranging from 0,50 to 6,0 m. in length and approx. 0,15 m. in height.
3. The cavitation tunnel.
The closed circulating water cavitation tunnel has two cross sections both of 300 by 300 millimeters. One measuring section is dedicated to measurements on friction drag reduction by air lubrication, the other is specialized for measurements on cavitation vortices.
