Umberto Pugliese towing tank


The Umberto Pugliese towing tank is one of the largest worldwide. It is 470 m long, 13.5 m wide and has a depth of 6.5 m. It is equipped with a towing carriage that can achieve a maximum speed of 15 m/s. The towing tanks have many applications, mainly concerning resistance and propulsion tests for performance evaluation of proposed design. The size of towing tank no. 1 offers excellent capabilities for the investigation of large, self-propelled models of high-speed vessels (mono- or multi-hull, semi-planing and planing craft, etc.). Equipment and methodologies for testing submarines and sail boats are available. Various unconventional marine vehicles are also designed and tested. Tests performed include:
– Resistance and self propulsion in calm water
– 3-D wake surveys
– Vertical and horizontal planar motion experiments
– Resistance, self propulsion and hydrodynamic forces on submerged bodies
– Resistance, self propulsion tests for high speed marine vehicles
– Upright, yawed and heeled sailing yacht tests
– Tidal and current turbine tests
