This research is filled out through a 22-item questionnaire by 40 security and controlling officers of Bushehrvessels. The results of Kolmogrov-Smirinov test suggest that the data are normal and T-test has been used for questionnaire analysis. The findings indicate that failure in technical and security certificates, failure of qualification certificate, failure of machinery and electrical appliances, structural safety defects, failure of telecommunication equipment, failure of security in under 500 tons motor boats and traditional and metal vessels [1]. As well, above 500 tons vessels traveling to Bushehr waters (state vessels) have suitable conditions.展开更多
