Environmental Analysis Research Group


 This group not only engages in research by freely using various analyzers but also establishes analysis and evaluation techniques to solve issues related to chemical, material, and environmental fields caused by ships. For example, this group operates its test marine diesel engine under various conditions, analyzes the emitted substances from different angles, and performs measurements to evaluate the effects of technologies that reduce the environmental impact of substances. This group aims to contribute to the reduction of emissions of environmental impact substances. This group also aims to realize an environment-friendly ship by clarifying the behavior of antifouling substances for ship bottom antifouling paints in seawater. The results of these studies are used as technical data to make recommendations to the International Maritime Organization (IMO).
 In addition, this group is conducting research on material properties using advanced analytical techniques such as electron microscopy and X-ray analysis equipment.
