Abstract
A ship that reduces the total amount of fossil fuels and other energy sources required, thereby saving energy. The ship () has a plurality of subsystems () constructed by dividing a network of power supply lines () and signal lines () into groups. The subsystems () consist of at least two subsystems among a bridge subsystem () on the bridge; a propulsion subsystem () in an engine room; a deck subsystem () installed on a deck; a ballast cargo subsystem () for ballasting and equipment installed in a hold; and an information processing subsystem () corresponding to communication equipment. The subsystems () each have a storage battery () and a smart meter (), each of which is linked to a microgrid monitoring and control system (), which detects the amount of electric power consumed by the subsystems (), and controls the transfer of electric power between the subsystems.
