Abstract

Beginning in July 2009, a California regulation has required ocean-going vessels (OGVs) to use marine distillate fuels with progressively lower fuel sulfur contents when within 24 nm of the California coastline (including the islands) and while in port. Since January 2014, OGVs are required to use marine distillate fuels with a fuel sulfur content of 0.1% or less by weight. The North American Emission Control Area (ECA) began implementation in August of 2012 and also established fuel sulfur requirements. In January 2015, the ECA fuel sulfur limit was lowered to ≤ 0.1% by weight consistent with the California regulation. However, the ECA does not specify the use of marine distillate fuels and OGVs may use non-distillate fuels, such as a low sulfur heavy fuel oil to comply with the ECA requirements. This work presents the in-use criteria pollutant emissions and ultrafine particles from a modern very large crude oil carrier (VLCC) while operating on two different fuels: a marine gas oil (MGO) with less than 0.1% sulfur fuel and a novel low sulfur heavy fuel oil (HFO) that has a fuel sulfur level less than 0.1%. Measurements in this study followed the International Organization for Standardization (ISO) 8178 sampling procedures and protocol for in-use emissions testing and sample analysis. The overall plan focused on the measurement of the gaseous and particulate emissions, including: carbon oxides (CO, CO2,), oxides of nitrogen (NOx) and particulate matter (PM2.5), while the chosen engine operated at steady-state conditions specified in ISO 8178 with either California/ECA-compliant marine gas oil (MGO) or the new, low sulfur HFO that can be used to meet the ECA requirements.
