Environmental Analysis Research Group


 The Environmental Analysis Research Group not only engages in research by making full use of various analyzers, but also establishes analysis and evaluation techniques in order to solve issues related to chemical, material, and environmental fields caused by ships. For example, we operate our test marine diesel engine under various conditions, analyze the emitted substances from various angles, and also perform measurements to evaluate the effects of technologies that reduce environmental impact substances. We aim to contribute to the reduction of emissions of environmental impact substances. We are also aiming 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, we are conducting research on material properties using advanced analytical techniques such as electron microscopy and X-ray analysis equipment.
