Abstract:

A 3-D oil spill model was developed to study the behaviour of heavy spilled oil in the sea. The model could describe the behaviour on the spilled oil on the sea surface, throughout the water column and sedimentation process on the bottom, by using the empirical formula derived from the laboratory experiments. The model results show that the spilled oil could settle on the sea bottom, if the specific gravity of spilled oil increased due to fire, adsorption of the heavy component of oil to the suspended matter and emulsifying process.
