  • Benefits of Two Mitigation Strategies for Container Vessels: Cleaner Engines and Cleaner Fuels.
  • Khan MY, Giordano M, Gutierrez J, Welch WA, Asa-Awuku A, Miller JW, Cocker D.AbstractEmissions from ocean going vessels (OGVs) are a significant health concern for people near port communities. This paper reports the emission benefits for two mitigation strategies, cleaner engines and cleaner fuels, for a 2010 container vessel. In-use emissions were measured following International Organization for Standardization (ISO) protocols. The overall in-use nitrogen oxide (NOx) emission factor was 16.1±0.1 gkW-1h-1, lower than the Tier 1 certification (17 gkW-1h-1) and significantly lower than the benchmark value of 18.7 gkW-1h-1 commonly used for estimating emission inventories. The in-use particulate matter (PM2.5) emission was 1.42±0.04 gkW-1h-1 for heavy fuel oil (HFO) containing 2.51 wt % sulfur. Unimodal (~30 nm) and bi-modal (~35 nm; ~75 nm) particle number size distributions (NSDs) were observed when the vessel operated on marine gas oil (MGO) and HFO, respectively. First-time emission measurements during fuel switching (required 24 nautical miles from coastline) showed that concentrations of sulfur dioxide (SO2) and particle NSD took ~55 minutes to reach steady-state when switching from MGO to HFO and ~84 minutes in the opposite direction. Therefore, if OGVs commence fuel change at the regulated boundary, then vessels can travel up to 90% of the distance to the port before steady state values are re-established. The transient behavior follows a classic, non-linear mixing function driven by the amount of fuel in day tank and the fuel consumption rate. Hence, to achieve the maximum benefits from a fuel change regulation, fuel switch boundary should be further increased to provide the intended benefits for the people living near the ports.
