Alternative Power Options for Improvement of the Environmental Friendliness of Fishing Trawlers

The fishing sector is faced with emission problems arising from the extensive use of diesel engines as prime movers. Energy efficiency, environmental performance, and minimization operative costs through reduction fuel consumption are key research topics across whole maritime sector. Ship emissions can be determined at different levels complexity accuracy, i.e., by analyzing ship technical data assuming its profile, or direct measurements parameters. This paper deals analysis footprint a trawler operating in Adriatic Sea, including three phases Life-Cycle Assessment (manufacturing, Well-to-Pump (WTP), Pump-to-Wake (PTW)). Based on consumption, viability replacing conventional diesel-powered system alternative options analyzed. results showed that fuels such LNG B20 represent easiest solution would result harmful gases have positive impact overall costs. Although electrification hydrogen one cleanest forms energy, due to their high price complex application an obsolete fleet, they do not present optimal for time being. effect emissions, but further work needed find environmentally acceptable economically profitable pathway redesigning power trawlers.
