QinetiQ's Ocean Basin is one of the largest hydrodynamic facilities in the World. Free-Manoeuvring models are controlled remotely using the latest wireless technology. Two-way real time communication is possible, allowing feedback of parameters such as pitch and roll. Model motion can be accurately captured and recorded by the Qualysis Motion Capture System to provide high quality information regarding performance. The wavermaker is capable of generating regular, irregular long or short crested waves, and our large basin size allows us to test the response of the vessel to waved from any angle. The wavemaking capability also allows investigation of floating, moored and offshore vessels and structures.
