Oil Spill Detection

How to detect oil using radars; advantegous or the SeaDarQ system; examples of automatic spill detection and validation and testing results.

The Nortek SeaDarQ system is an Oil Spill Detection system. Oil Spill Detection is the main function on which we focus and you will see that in your results.

Benefits to the user

  • Oil Spill are detected automatically. The system monitors the sea surface constantly and will give and show a warning when a suspect area is discovered. The alarm will sound when oil is detected.
  • Low false alarm rate. To detect oil is one thing but to get false alarms is annoying. We have gone great length to make sure that we detect oil and do not alarm on shadows behind vessel, shadows behind and natural phenomena at sea and many other causes.
  • The User Interface is clean. Suspect areas and detected spills are shown in color, the rest of the information i in black, white and grey.


SeaDarQ Hydrography gives you currents and depth information at high resolution and high update rate.

Would you like to see currents and depth information in an area of a radius of several kilometers ? Would a resolution of 100×100 m be enough ? And an update rate of 10 minutes ?

The image below shows current vectors (yellow) at the sand engine location in The Netherlands. Processed radar data of the sea surface is shown as an underlay. Together these give a very good insight in the structure of the current at the site. The structure is complex due to the coastal extension and the mixing of salt seawater and the fresh water outflow of the river Rhine. 

The data is being used by researchers and coastal management to position measurement equipment like ADCPs and to improve swimmer safety.
