OSD3000 - Oil Spill Detection

Researching in small target detection based on radar makes it necessary to search for targets with a signal to noise (clutter) ratio of less than 1.

In order to detect targets in such environments VisSim has developed an extensive library of pattern recognition and parameters analysis algorithms for studying of sea clutter. For this research VisSim has developed a Video Extractor Module, which acquires radar data with a high sampling rate (up to 100 MHz) and delivers raw digitized radar video for different radar video processing applications.

The technology we are using for acquisition of radar signals allows us to perform several types of processing based on the same radar, e.g. tracking targets for VTS purpose, detecting Oil Spills, calculating wave parameters, etc.

The Oil Spill Detection module is based on raw video from commercial X-band radars, independent of the make. Typical suppliers of these types of radars are: Sperry Marine, Furuno, Raytheon, GEM, Terma, Atlas, etc. Preferable antenna size is 6 ft or above.

The following screenshot shows automatic detection of the slick from spill of oil emulsion from Statfjord A platform in may 2008.

We started research in Oil spill detection and sea clutter analysis based on standard marine radars in 2002. The first development was a module for operator assisted oil spill detection. Then we developed a fully automatic solution, which will run as a “background” application in our VTS installations monitoring oil spills around oil platforms, in ports and along coast lines providing an early warning of possible oil spills for VTS operators. Later Oil Spills Detector program was extended with Wave Parameters Measurement module based on sea clutter analysis in X-band marine radar. This module can provide possible oil slicks detection and wave parameters measurement.
