AI Technical Summary

Technical Problem

Existing technologies are unable to obtain unified statistical data for dry bulk terminals, resulting in the inability to accurately calculate the reduction in particulate pollutant emissions during the use of shore power by ships at port, and the inability to effectively promote the use of shore power and formulate emission reduction policies.

Method used

This paper provides a method for calculating the reduction of particulate pollutant emissions during the use of shore power by ships at dry bulk terminals, which is based on the difficulty of obtaining statistical data at different levels. The method uses three levels of calculation methods: based on the number of ships using shore power, throughput or time, combined with the type of auxiliary machinery, terminal operation process and dust pollution prevention and control measures, the reduction of particulate pollutant emissions is calculated.

Benefits of technology

It has achieved accurate calculation of the reduction in particulate pollutant emissions during the use of shore power by ships, promoted the efficiency of shore power use at the terminal, solved the problems of ship pollution supervision and environmental protection, and provided an effective reference for policy making.

Abstract

The invention discloses a method for accounting emission reduction of particulate pollutants in a ship using shore power period, and the method comprises the steps: S1, proposing a first level for accounting emission reduction based on the number of ships using shore power according to the difficulty of obtaining the statistical data of a wharf, the second level is used for accounting the emission reduction amount based on the shore power ship throughput or the shore power time, the third level is used for accounting the emission reduction amount based on the shore power usage amount, and the selection priority sequence of the third level > the second level > the first level is that the third level > the second level > the first level; s2, according to the selected level, acquiring data for accounting the emission reduction amount of particulate pollutants during the period when the ship uses the shore power; s3, the emission reduction amount of particulate pollutants during the shore power utilization period of the ship is calculated; according to the method, three data analysis levels with different priorities are set based on relatively large management differences of different wharfs and different data acquisition difficulty levels, so that the method is suitable for all dry bulk cargo wharfs to use, and effective accounting can be realized on the emission reduction amount of particulate pollutants during the ship shore power use period.
