Current problems and risk analysis on high pollution risk operation of ship

As we know, there is a great risk of pollution during the process of typical operations, such as tank cleaning, liquid hazardous goods barging, tank dismantling and wreck salvage. Especially for tank cleaning and tank dismantling operations, the pollution risk is more prominent since the small-scale private companies and the low quality of employees relatively. In order to prevent and control pollution of ships and their related operations to the marine environment, China has issued a number of laws and regulations. This paper reviews the relevant domestic legal system, and summarizes the present situation of typical high pollution risk operation of domestic ships. By analyzing the characteristics of high pollution risk of such operations, risk analysis is carried out. The research results are of great significance for regulating the high pollution risk operation of ships, reducing the pollution risk, improving the safety during operations, and preventing pollution from ships and related operations to marine environment.
