| Summary: | The purpose of this research article is to perform a greenhouse gas (GHG) impact assessment using a lifecycle analysis of a cold-ironing solution for vessels at anchorage in a retrofitted barge and a marine genset combusting biomethane in dual fuel mode. A lifecycle methodology is developed based on the 4th International Maritime Organization (IMO) GHG study. Eleven impact scenarios are evaluated in terms of CO<sub>2</sub> and harmful pollutants (SO<sub>x</sub>, CO, PM<sub>10</sub>, PM<sub>2.5</sub>, NMVOC, and NO<sub>x</sub>). Vessels operated by Petronav Ship Management Ltd are examined, specifically M/T Alexandria and M/T Astraia. The scenarios reveal CO<sub>2</sub> reductions of up to 21% and CO increases of up to 60% due to the combustion of biomethane in dual fuel mode, alongside SO<sub>x</sub> reductions of up to 20% with increasing biomethane energy substitution. Particulates and NO<sub>x</sub> decrease due to the utilization of biomethane. This article presents a pragmatic solution for cold ironing for vessels at anchorage with proven lower GHG emissions with the exception of increased CO emissions, therefore the benefits outweigh the drawbacks. |
