Study on Characteristics of Ship Emissions from Surrounding China Seas

Abstract

In order to analyse the characteristics of air pollutants emissions from coastal vessels in China, this study collects and analyses the static data and emission parameters of ships both at home and abroad based on the data of automatic identification system. Based on the actual navigation Data of ships, the paper also analyses the emission characteristics under the condition of five vessels including port, mooring, low speed and cruise in port, and statistics the emissions according to different sea areas, and gives the ship atmosphere of the three emission control areas In China Pollutant emissions. The results show that the SO2, NOX and PM10 produced in the vicinity of China's coastal waters within a year are about 879,800 tons, 1,378,400 tons and 117,300 tons, respectively. Source of emission analysis shows that the host is the main source of emissions from the three main sources of emissions on the ship's main engine, auxiliary engines and boilers. Spatial analysis of ship-borne pollutants shows that 90% of ship emissions occur within 96 nautical miles of the coastline to the baseline of the territorial sea.
