Towing Tank at HSVA


The institute operates a towing tank, which is located at HSVA.

Test Section Dimension  

The test section is 80m long, 5m wide and 3m deep.

Towing Carriage

The carriage operates at a maximum velocity of  approximately 3.5m/s. Models from 2m to 6m can be towed. The height above the water surface is 0.8m.

Wave Maker

Waves between 0.3m and 6m can be generated with the plunger type wave maker. 

Data Aquisition and Measurement Techniques

The tunnel has computerised control system. A modern state-of-the-art data-processing software and  hardware supports to make maximum use of the facility.

A number of measurement techniques for the acquisition of hydrodynamic quantities are available, amongst them are a 6 DOF inertial system, consisting of three fibre-optical gyro sensors and three acceleration sensors, for survey of motions during manoeuvring and seakeeping tests.
