Sažetak
Reduction of ship emissions is nowadays one of the most important research topics in maritime sciences. This is particularly true for decarbonization, where different technical and operational measures, as well as various business strategies, are being investigated to reduce carbon dioxide (CO2) emissions. Fishing vessels generally do not belong to these categories, but their effect on humans and environment is very important since fishing operations are mainly performed in coastal waters. On the other hand, fishing vessels are mainly equipped with an outdated low-efficient diesel engines resulting in relatively high emissions. In Croatia, fishing has a long tradition and the indented coast of the Adriatic, as well as the rich sea, have enabled the coastal population to engage in fishing for generations. The Croatian fishing fleet includes 5% purse seiners, which make the largest amount of catches. This paper investigates the possibilities of implementing alternative fuels in power systems of purse seiners and their effect on the reduction of CO2 emissions. 5-year data on fuel consumption and catch of purse seiners with different technical characteristics from the Croatian fishing fleet are used to calculate the level of emission release of possible solutions. Life-Cycle Assessment (LCA), which includes the ship operation and the process of fuel supply, is used to compare a diesel-powered configuration with alternative ones. In conclusion, a complete assessment of the efficiency of alternative fuels is given and guidelines for further research are proposed.
