Estimation of Marine Emissions in Zhanjiang Port Area Based on AIS Data

In order to clarify the pollution gas structure of ships in the Zhanjiang Port area, it proposes targeted ship monitoring measures in the port. In this paper, the statistical data of ships in Zhanjiang Port area are extracted from the ship automatic identification system. The results show that the ship type with the largest contribution rate of exhaust emissions from Zhanjiang Port area is the cargo ship. Among the components of exhaust gas emissions, the gas with the highest contribution rate is CO2. In the operating conditions, the sharing rate of parking conditions is the largest. It shows that AIS is convenient and operative based on the calculation of regional seaborne emissions by data.
