The western Black Sea is a busy sea where ship traffic is intense and used by 6 riparian countries for export and import. This water area is a region with a high economic and ecological value, which is extensively exploited from marine living resources by sea trade. In recent years, in addition to the transportation and living resources of the Black Sea, seabed resources have also become important. In particular, importance has been given to oil exploration. Oil exploration areas being located in the north-south transition areas of the western Black Sea, where ship traffic is heavy, increases the risks of platform and ship accidents. The oil that will spread after an accident that may arise from the platforms in the same area will create significant environmental risks. In the study, the ship traffic routes in the oil exploration areas in the Black Sea were determined and the risky areas on these routes were revealed. Then, the oil distribution area and budget that will occur after a platform ship accident that may occur in these regions have been determined by simulation. In terms of ship traffic, it has been understood that the Sinop and Ereğli offshore areas constitute risky areas. In terms of oil pollution, the most important risk areas in the western Black Sea were identified as Kefken coasts.
