Measuring Marine Engine Emissions
Support vessels, fishing vessels, passenger boats, and port fleets: marine engines are subject to increasing scrutiny regarding the quality of their emissions, driven by policies to monitor air quality in port and coastal areas.
The measurement principles remain the same as those we use for automobiles—exhaust gas analysis, smoke opacity, and particle counting—but the conditions under which they are applied have changed: access to the exhaust system, engine speeds, the saline environment, and the confined space of engine rooms.
