Unique selling points
The facility, equipped with a state-of-the art motion capture system installed by Qualisys™, is used primarily for constrained and free-manoeuvring surface ship and submarine model tests in calm water or waves.
Free manoeuvring surface models are fitted with infra-red emitting markers (typically four) and tracked using 16 cameras distributed around the basin. The specification of the Qualisys™ system is: spatial resolution: 0.3 mm; relative accuracy: ± 3 mm; measuring frequency: 1-100 Hz in real time; simultaneous tracking: up to five models.
Technical features
- 40,000 tonnes of clear water
- Free-manoeuvring models are controlled remotely using the latest above and underwater wireless technology
- Wavemaker comprises 122 independently actuated paddles, which can generate regular, irregular, long/short crested, transient, and breaking waves, which can also be user defined
