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.
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.
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.
