heal.abstract	Assessment of an oil-spill behaviour in the maritime environment is absolutely necessary, as a great amount of petroleum is transported by cargo ships and pipelines through this environment. Moreover, the increase in offshore oil exploration, and the drilling and production activities enhance the potential for oil spills that damage the marine ecosystems, given that oil toxicity creates major environmental problems. Assessment of the impact of an oil spill on the marine environment may be based on mathematical models, that appear to be important tools for relevant studies. This paper describes a general deterministic model developed to simulate the time-dependent behaviour of oil spills near coastal regions a? well as in the open sea. The model solves the full Navier-Stokes equations for transient two-phase, three-dimensional turbulent flow, heat and mass transfer, including most of the important aspects of the physical, chemical and biological processes that govern the behaviour of oil slicks at sea. The solution method is based on the finite-volume method. The model capabilities are demonstrated by applying it to oil spills at two coastal regions; near Carava, at the island of Lesvos, and near Eretria, in the Evvoikos bay, both being in the Aegean sea, Greece. It is concluded that meaningful and useful results are obtained within reasonable computer resources. © 2008 Civil-Comp Press.	en
