Application The main objective of this project visual images of ships exhaust system real-time monitoring and video evidence collection , control and audit quickly implement contingency measures against ship pollution , while applying remote sensing technology to monitor the harbor pollution situation , assess the effectiveness of pollution control measures , a shipping sulfur content of oil surveys and research PM2.5 emission characteristics of Keelung area and plan effective control strategies.
The project application CCTV video surveillance system to monitor ship operations smoke , 102 years since the end of April to 12 , recording a total of 130 abnormal situations smoke and smoke for seven abnormal situations ( six exceptions, a public petition ) be informed of the EPA and Keelung Keelung Harbor Branch , field personnel to determine opacity does not exceed 40% , non- smoking violations improper circumstances , have switched to include follow- main track objects. Another follow-up work for the year and out the exhaust port and ship exhaust situation shows that smoke -compliance is still the main harbor and naval -based Star Cruises . Another oil with sulfur content of ship Port sampling and analysis , to understand the main ship oil usage , until the end of October to complete the 20 samples analyzed ( 10 heavy oil , diesel 10 ) , the results showed that the sulfur content of oil under test Petroleum oils sold in volume within specification range and far below the MARPOL 73/78 Convention norms .
New Year smoke image recognition task , the use of image recognition technology to identify the ship exhaust be assessed . Ships accuracy of image recognition system for ship identification and visual exhaust smoke sentence has been compared to about 85% can be achieved , and with automatic notification system detects smoke can instantly get the message to do the relevant response , the use of automatic identification system will be able to enhance the efficiency of artificial visual and enhance automatic detection of the instrument for the future of the ship determination of smoke will have some help.
Archives UV-DOAS monitoring results show that Port Sulphur dioxide (SO2) and nitrogen dioxide (NO2) and the daily average concentration of Keelung station contrast, sulfur oxides (SO2) part , Keelung area air quality monitoring stations compared to the average height of 2.3 times ; nitrogen oxides (NO2) part , Keelung area air quality monitoring stations compared to an average high of 28% , and the other benzene (Benzene), toluene and on - the concentration trend xylene (p-Xylene) of no significant correlation. Japan and China in various unusual events , and videos through the upwind direction confirmed a significant impact on ship exhaust sulfur dioxide (SO2). Monitoring results for the present and the prevailing wind direction display , ship smoke on gaseous pollutants SO2, PM10 and PM2.5 sources of suspended particles have a significant effect .
Fine suspended particles PM2.5 monitoring, sampling analyzers with automatic and manual sampling of two parts , PM2.5 automatic and manual sampling and analysis results, while manual monitoring results section and the measured value of the project compared with the EPD , the two trends are still similar. Another analysis of the prevailing wind direction during the monitoring period showed that the ship had to exhaust gaseous pollutants SO2, PM10 and PM2.5 sources of suspended particles significantly affect to the prevailing wind direction , the main factors causing increase in pollutant concentrations Port to Port activities around as the main source ; secondary aerosol derived part to NOR SOR value and value terms during the year to perform the detection of ( May 27-July 28 ) primarily from the conversion of local pollutants generated ; according to NH4 + utilization index J value and I value parsed , I value greater than 2, J value of less than 1 indicates that most of the local pollution sulfate and finished with NH4 + in nitrate -free medium and finished, it should control nitrate , in addition to control of nitrate reduction in PM2. 5 of the form , for solving the problem of ozone will also help the city .
Monitored by UV-DOAS , PM2.5 component analysis, estimate wind speed and direction and the number of ships entering and leaving the harbor , such as cross- comparison, estimated within the port activities ( including the ship out of port and vehicle access , etc. ) significantly affect Hong Kong changes in the measured value of the SO2 in the region ; international trends, future oil 2020 tightened to reduce the sulfur content to 0.5 % or less, the current measured value of oil , were much higher than this standard.
Above, to maintain the quality of ambient air , Minato , in addition to strengthening the future of ship oil control operations , should also be on the road within the port speed access to the ship , the ship smoke behavior , Minato surrounding behavior to regulate mobile sources of pollution , and implement Minato such as the use of shore power , thereby reducing air pollution within the port fact , maintaining good air quality and public life .
