With the increase in the pollution caused by oil industry developments and related infrastructures in the last century, setting priorities for decisions in sensitive coastal areas to oil spills is important. This study uses the reports in the field of environmental sensitivity index in shorelines and applies the Delphi method to determine the criteria and sub-criteria allowed for adjusting the effective hazard components of the shoreline to pollution. Finally, using hierarchical analysis and network analysis methods helped in determining the priorities of the indexes in the evaluation of the shoreline hazards to oil spills. This study compares priorities by utilizing Expert Choice software for hierarchical analysis and Super Decisions software for network analysis process within the framework of multi-criteria decision-making methods. Based on this, biological resources, socio-economic resources of pollution, the physical characteristics of the shorelines, and the related sub-criteria were prioritized. Accordingly the final ANP/AHP maps are produced by using Index Overlay method.

This paper presents a three- dimensional numerical model for prediction of the movement of oil slicks from a spill accident in the Strait of Singapore. The results of this model are compared with the results of the model which was run by Chao et al. This model has previously been developed for prediction of movement of gas condensates from spill accidents in the Assalouyeh marine Oil and Gas region and has achieved good results. The model is simulated based on the solution of the Navier-Stokes and the continuity equations. For the solution of advection term an upwind weighted multidimensional positive definite advection transport algorithm (MPDATA) used. This algorithm uses an explicit finite difference scheme with an anti-diffusive velocity for equilibrium diffusion. Comparison of the results of the two models showed good consistency that is considered for the introduced model as a reliable verification.
