| Abstract: | The failure modes of the marine boiler water supply are discussed based on the Probabilistic Risk Assessment method.The water supply system fault tree has been established and the minimum cut sets are obtained.The probability of the water supply system and the importance of root nodes is calculated by the Monte-Carlo simulation method.Some improvement advices are offered in the end. |
