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.

Environmental Friendly Technology!

Next Ocean's wave predicting technology is acknowledged being an environmental friendly technology by the Dutch Government. Short term wave predicting technologies enable more efficient use of ships. Therefore the use of such technology is stimulated by tax reduction via the MIA(36% investment reduction on fiscal profit) and VAMIL(75% variable write off) regulations.

Technology

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.

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.

The system is currently undergoing operational tests in the North Sea. Test results are expected by the end of 2017. The Next Ocean wave prediction system is targeted for market entry in 2018.

Product

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

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 Wave Predictor foresees a window approaching in the near future where the waves or resuling ship motions are within set limits and which is of sufficient lenght 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.

 

Consultancy

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.
