Study on Life Cycle Impact Assessment for Ships

概要

We have developed LCA software to estimate the environmental impact of a ship during its life cycle. We incorporated a recently developed comprehensive life cycle impact assessment (LCIA) methodology, called LIME, which quantifies the potential environmental risk and creates a single economic index specific to Japan's conditions. Analysis was conducted on a bulk carrier based on data obtained from field studies at a shipbuilding yard and a dismantling yard and on the analysis of navigation logbooks of actual bulk carriers. The results of stage-by-stage analysis clarified that almost all the environmental impact during the ship's life cycle occurs at the operation stage and that the primary environmental impact categories are acidification, global warming, resource consumption and urban air pollution. Based on the LIME index, the result also made it clear that the emission of CO_2, NO_x, SO_x, NMVOC and PM as well as the consumption of crude oil are major environmental load items contributing to environmental impact during the ship's life cycle.
