Research on Fault Tree Analysis of Ship Electrical Accident Based on Cloud Model

In the context of economic globalization, the commercial trade between countries is increasing. Sea transportation is a mode of cargo transportation widely used in international commodity trade. However, electrical accidents in the process of ship work will affect the normal cargo transportation and have a certain adverse impact on economic development. With the rapid development of science and technology, many advanced electrical equipment and various components are also applied in the process of ship design and manufacturing. Because the technology and operation are not perfect, there are certain potential safety hazards in electrical grounding, which affects the safe operation of the ship. Therefore, it is necessary to discuss the electrical faults of the ship. In this paper, the diagnosis method of ship electrical fault is analyzed by using cloud model theory, and the qualitative analysis results are obtained. Then it further expounds the treatment methods, which is of great significance to improve the safety of marine electrical equipment.
