MEASUREMENT AND ASSESSMENT OF GAS EMISSIONS FOR MARINE DIESEL ENGINE

Abstract

Vietnam currently fully participates in Annex VI - "Regulations on air pollution prevention by ships” of International Convention for the Prevention of Pollution from Ships (MARPOL 73/78). Therefore, the Vietnamese fleet needs to meet the strict requirements of IMO on emission control in accordance with the roadmap that has been set up. In order to do this, Vietnam needs to build a laboratory system and set up the process of measuring and assessing the conformity of emissions standards according to international standards to ensure the implementation of the convention and NO_x Technical code of all ships when arriving at member countries ports. A applicable option for measuring and evaluating on-board emissions is the use of high-precision portable emission measurement devices. The results of studies show that portable emission measurement device gives quick results, ensuring accuracy when directly measuring on ships at ports.
