WaveGuide 5 Direction Onboard 2

The next level of our innovative wave radars: measuring waves, directly from a
floating structure. A motion compensated (roll-pitch-heave) version of the unique directional system.
It accurately measures wave direction, wave height, wave period and draught.
No water contact, no maintenance and no (re-) calibration. So no hassle.

The WaveGuide 5 Direction Onboard 2 is an easy to use, reliable and robust device to measure draught, wave direction, wave height and wave period. The sensor is capable of maintaining a high level of precision and accuracy in harsh environmental conditions.

And is particularly suited to floating offshore installations such as floating turbines, semi-subs, FPSO’s and other offshore vessels.

1) Valid for a still water surface.
2) For a water surface with waves.
3) The accuracy of the wave parameters is not limited by the radar sensor, yet it is defined by the stochastic nature of sea-surface measurements. 4) SWAP is the Standard Wave Analysis Program, in accordance with the applied standards of the Dutch Ministry of Infrastructure and Environment and of the International Association of Oil and Gas producers.
5) The wave period is not compensated for the horizontal motion. Hence, for a moving vessel, the sensor measures the wave period as encountered by the vessel. 6) Wave direction is given with respect to the vessel heading.
