Read the waves and predict the vessel motions
Scan the sea surface
The x-band radar scans the sea surface. By means of Bragg Scatter reflections a digital map of the sea surface is derived. This is a continuous process. Sophisticated signal processing is applied to get the best possible view on the waves.
Propagate the waves
The Next Ocean Proprietary software decomposes the sea surface into its underlying wave components, all with their own amplitude, frequency, direction and phase angle. This calculation is done real time.
Know your wave system and vessel motions
In a first pass, we calculate the wave spectrum, along with significant wave height (Hs), wave period (Tp) and the surface current.
Using linear wave theory and the wave to vessel motion transfer functions (also known as Response Amplitude Operators, or RAO) a prediction is made for the motions of the vessel, up to 240 seconds ahead of time. All 6 degrees of freedom (DOF). Self learning algorithms and AI driven system identification continually ensure the highest accuracy of the predictions. This accuracy is evaluated real time to provide the user with a prediction he can rely on.
The Motion Severity Index (MSI) and its limit can be defined for each relevant operation. The MSI is based on the motions and accelerations predicted for any combination of DOF and translated to the point of interest for the operation. This can be the tip of a crane, the A frame at the rear deck, the gangway or the helideck.

Quick, clear and safe
At a glance, you can decide if you have enough time to execute the critical step in your operation safely.
Our system monitors vessel motion in real-time, highlighting the motions that are outside accepted limits. The traffic light display ensures crews know what to do, making offshore operations safer and more efficient.
