Radac - Model Waveguide 5 – On Board -Accurate Wave Monitoring System
The WaveGuide Onboard installation compensates for the vertical motions of the ship, so it measures the waves the ship actually has to endure. This accurate wave monitoring system is an easy to use, reliable and robust device to measure vessel draft level, 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 maritime use.
The Onboard wave radar, mostly installed at the helideck, bow or bridge of the ship, measures the distance to the water surface. The distances measured are compensated for the heaving, pitching and rolling motion of the radar. Thanks to a highly sensitive motion sensor is incorporated into the radar unit. The WaveGuide Onboard measures the waves the ship actually has to endure.
The radar measures the distance to the water surface 10 times per second. The radar itself facilitates data acquisition, data processing, data presentation and remote service. Data will be internally stored on the device and distributed over the network. Any device connected to the (private) network can access the web-based user interface.

1) Valid for a stationary flat water surface.
2) 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.
3) 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.
