Abstract
Coastal areas due to geographic location, biodiversity and dependent ecosystems are sensitive and delicate areas. In this study, the sensitivity of the coastal ecosystems of the South Pars region has been determined, and the results have been evaluated by using Expert Choice software. Since, the south Pars region is constantly exposed to the drilling and extraction of the oil and gas wells, the Jack-up drilling platform is identified as one of the pollutant factors in the region and its effects as a pollutant factor on the Different ecosystems have been analyzed.  In order to assess risk through the basic definitions of risk assessment, as well as application of mathematical techniques, the probability, the severity of consequences, and the importance of habitat have been identified and calculated. In this study Fuzzy concepts are used for quantifying the qualitative parameters. In order to validate the results, the calculated mathematical model was compared with the actual values. The results of environmental events over a period of four years indicated the importance of considering environmental risks in drilling operation by jack-up, which is needed for management and protection of sensitive ecosystems in the region.
