The basin is fitted for floating structures of any kind. Models can vary between 3 and 6 metre of length. The size is depending on water depth and wave conditions (usually between 0.2 m for buoys and 4 m for platforms)

CARRIAGE

The carriage enables efficient testing and monitoring of offshore tests. The carriage can follow the movements of the model in both directions of the horizontal plane at a speed up to 3.2 m/s. With an extra installed turntable, the system is able to perform captive manoeuvring tests in shallow and deep water. Therefore rotating arm tests are possible.

ENVIRONMENT

Waves: Wave generators are positioned at two adjacent sides of the basin and consist of hinged flaps. Each segment (width 40 cm) has its own driving motor, which is controlled separately. The wave generators are able to simulate various wave types, such as short crested wave patterns. The system is equipped with compensation of wave reflection from the model and the wave absorbers. Opposite this wave generator, passive wave absorbers are installed.
Wind: For wind generation, a free moving and positionable platform of 24 m width, equipped with electrical fans is available.
Current: Current can be simulated with all kinds of profiles (hurricane, deep water current etc). Divided over the water depth of 10.2 m, six layers of culverts, each equipped with a pump, are installed.
Movable floor: The concrete movable floor has dimensions of 36  31 m and a height of 1.75 m.
Instrumentation: An optical tracking system is mounted on the sub carriage for the measurement of 6 D.O.F. model motions.
