4 Comparison of the emissions from the container vessel's boiler and the boiler on a crude oil tanker The emissions from the boilers depend heavily on the size of the boiler and the extent of their use. On the container vessels, boilers are usually used for auxiliary hotel loads while on crude oil lightering vessels the boilers are used for discharging the crude oil. In Table 4, the gaseous emissions from a tanker boiler in a past study3 are compared to the container vessel under consideration in this study. It is evident from Table

4 that the gaseous emissions from the boiler on a crude oil tanker are higher. Table 4: Comparison of the Gaseous Emissions from a Crude Oil Tanker3 and the Container Vessel (kg/tonne) Crude Oil Tanker
