COES's Spilt Oil Dispersion Information System has been developed to predict the location of impact from a particular source, its movement and trajectory for entire China Offshore and shoreline. The analysis of spilt oil movement and property identifying based the data assigned of the speed and direction of currency and wind, has significantly helped operators in dealing with response more quick and precisely. The system can also predict the central point and the thickness, area, dimension of the spilt oil with adjustable function during the processing. The length of shoreline affected by the spilt oil can be carried out by this system since the database of sensitive area, the town onshore and the facilities offshore has been installed.

The system can also predict how wind, currents, and other processes might move and spread oil spilled on the water. This includes:-

• The trajectories are affected by inexactness ("uncertainty") in current and wind observations and forecasts.
• How spilled oil is predicted to change chemically and physically ("weather") during the time that it remains on the water surface.

The system has gone a long way to helping clients realize the significant benefits which can be achieved through improving the fast trace the spilled oil and then the efficiency of their response operations.
