Abstract: = 0.58), indicating additional influencing factors. These findings enhance understanding of transient engine behaviour and fuel economy, informing strategies to optimise ship propulsion and improve emission inventories in port environments. In line with MARPOL Annex VI, which mandates sulphur limits in marine fuels within environmental control areas (ECAs), this study employed ultra-low sulphur diesel (ULSD). While absolute emission values may differ, the observed trends are applicable to refined marine fuels such as marine gas oil (MGO) and ultra-low sulphur fuel oil (ULSFO).
