Wave Prediction

Waves play a major role during most offshore operations at sea. Unfortunately, sea waves behave in an irregular and unpredictable way. We know that waves occasionally exceed certain operational limits but we do not know when such waves occur. Till now...

Next Ocean’s prediction system has changed this: it predicts the actual time traces of waves approaching the ship and the resulting ship motion response. On-board and real time.


Gain Workability

Common practice is to take a statistical approach to operability: just a very low probability that a limiting wave event occurs is accepted. As a consequence the waves and resulting ship motions are well below the critical value during operation most of the time, leaving a huge gap in workability to gain.



Reduce Risk

Next Ocean predicts when and where high waves occur. This enables offshore operators to choose an optimal time window free of high waves for the most critical phase of their operation rather than wait for better conditions or ‘hope’ for the best.




Next Ocean Presents at Subsea Lifting Operations Conference in Stavanger

Alpha-Factors of greater than 1.0?! That was one of the discussion topics during the Subsea Lifting Operations conference in Stavanger past two days. MO4 and Next Ocean were invited by DNV GL to share the latest insights in ship motion forecasting technologies. The presentations of both Mark Paalvast and Peter Naaijen inspired the audience to think outside the box of conventional operational limits based on Hs and Tp. Great to see what these innovative technologies offer the offshore sector!

Next Ocean to Conclude Successful PSV Trial

Beginning of this year Next Ocean joined forces with Vroon Offshore Engineering to setup a trial with the Next Ocean WavePredictor on one of Vroon's Platform Supply Vessels (PSV). During the trial the WavePredictor proved to be capable of predicting waves and ship motions live during offshore operations. As it was the first live trial the crew did not use the system's output in their operations yet. However, the crew reported that the WavePredictor would significantly improve their awareness of incoming waves and potential loss of DP position in marginal conditions. Escpecially during operations at night.

Next Ocean Delivers Technology for The Ocean Cleanup

On the 8th of September The Ocean Cleanup launched their first plastic capturing system from San Francisco Bay into the Pacific: System 001. The coming several months System 001, nicknamed ‘Wilson’, is tested thoroughly and they hope to bring back the first batch of ocean plastics. Next Ocean’s technology is installed on board the ship that stays near the system and continuously keeps an eye on her during these first exciting months. With our technology we help The Ocean Cleanup to better understand the behaviour of the barrier in the wind and waves at the ocean. We are glad to contribute in this way to this much-needed project. We wish The Ocean Cleanup team a thriving continuation and many successful plastic catches!

The main input for Next Ocean’s wave prediction system comes from the ship’s navigation radar. An additional dedicated radar antenna is therefore not required but can optionally be installed.

Using established technology the directional wave spectrum and surface current are derived from the raw radar data. In addition to this technology, Next Ocean has developed new algorithms that provide valuable extra information: real-time prediction of approaching waves and the resulting ship motions minutes in advance.



Scanning the waves using the ship's navigational radar.



Radar energy reflects off sea surface.



Raw radar image. When no filtering is applied wave patterns are visible.




Next Ocean offers a complete hardware and software setup that enables real time wave and ship motion prediction on board of your ship: the 'WavePredictor'.

The hardware can be installed and tested within one day. Various options to directly purchase or rent the device for projects are available.




  • Red light: seconds to next workable window
  • Green light: seconds left to safely perform operation


The interface provided by Next Ocean consists of a traffic light and a timer. The traffic light shows whether or not a situation is 'workable'.

When the WavePredictor foresees a window approaching in the near future where the waves or resulting ship motions are within set limits and which is of sufficient length it starts to count down till this workable window reaches the ship.

As soon as the workable window reached the ship the traffic light jumps to green. The timer starts to count down again, this time till the end of the workable window.



For those interested in using the raw Next Ocean algorithm’s output in their own wave analysis and ship motion computer models, Next Ocean offers this possibility on a consultancy basis. We can help you to integrate our software within your own solutions.

About Next Ocean

Next Ocean is a Spin-Off from the Delft University of Technology. The company is founded in 2016 by Peter Naaijen and Karel Roozen. The company has its office in the Buccaneer, an energy and offshore accelerator situated in the city center of Delft.

Peter studied Maritime Technology at Delft University of Technology, specializing in Ship Hydromechanics. During past 12 years, Peter held a position as an assistant professor at the Ship Hydromechanics dept. of Delft University of Technology. Since 2008, Peter’s main research topic has been deterministic wave and ship motion prediction from ship radar, leading to various publications.

Karel studied Maritime Technology at Delft University of Technology where he specialized in Ship Hydromechanics. Right after his studies he started as a freelance engineer in the field of ship motion calculations. Nowadays he committed himself to commercializing the wave predicting technology.
