Abstract
This body of work proposes the study of the community impacts from hazardous air pollutants (HAPs) from various sources. Composed of several studies, the first being real-time composition of tier II marine vessel emissions and comparing the efficiency to tier III OGVs. Both vessels have been built by the same shipbuilder and engine manufacturer. This study will serve to quantify the chemical composition and concentration of HAPs from marine vessels between the two technology classes and regulatory fuel blends. A full spectrum of samples has been taken from the main engines at various speeds with respect to the regulated engine load points based off of the ISO 8178 testing cycle. Samples will be collected with the two regulated fuels used in operation. Work shown will be gathered from two tier III vessels, and one tier II vessel. All three engines being classified as category 3. Full speciation analysis will show the OC:EC ratio, as well as present HAPs from the stack emissions.
