Abstract:

In order to further improve the classification and grading of hidden dangers of offshore oil in China, relevant laws and regulations, as well as departmental rules and standards were collected. Based on the characteristics of the offshore oil industry, the hidden danger was defined, and its classification principles were elaborated. The classification standards of hidden dangers issued by administrative departments, different industries, and oil companies were compared, and the classification method of hidden danger of offshore oil in China was given. The grading standards of hidden dangers issued by administrative departments, different industries, and oil companies were also compared. On the basis of the classification of hidden dangers in the department of emergency management, the grading method for hidden dangers of offshore oil in China was proposed. The results show that the proposed classification method of hidden dangers of offshore oil can be further extended to seven major categories such as operators, designs, equipment and facilities, materials, environmental conditions, management, and compliance, as well as 43 subcategories. The hidden dangers of offshore oil are classified into six grades: ″one vote veto″, particularly significant, major, comparatively major, general, and minor.
