Abstract
It is very important to prevent the ships from global environmental pollution and to reduce emissions of greenhouse gases. So it is considered very useful with the object of the prevention of environmental pollution to use hybrid ships which operate by batteries in case of it is near from human habitation and they operate on port district is easy to give off an exhaust is produced by the incomplete combustion by the start and stop of the engine. Therefore, in this report, we consider to navigate by all the batteries when it comes into and leaves a port, and it calculates necessary battery capacity, size and charging time, as an example, it cover the several ships navigates in Tokyo Bay, and we discuss about navigation methods to take on batteries of large capacity. It values at number of a container in the way of the batteries put in a familiar container for the ships as for battery size. This shows between superimposed capacity of the cargos etc and battery size, and it complies battery capacity which mounted, and this report discusses battery about the charge methods and the battery charge time. And it shows practical navigation methods as hybrid ship.
