Abstract
Amid calls for the reduction of greenhouse gases to prevent global warming, the marine industry has been considering strategies and countermeasures. This time, it was decided that an onshore power supply system will be installed for the first time in Japan on a large ferryboat on an exploratory basis, and at the same time the world’s largest-class photovoltaic power generation system for marine use will also be installed on the ship. This article describes this project and its background and provides the project’s technical aspects.
