Abstract

Japan Coat Guard was established in 1948. The fleet of patrol vessels has been constructed and played an important role in rescue activity and law enforcement. It is an issue to replace smoothly old vessels by modern ones. Some groups of patrol vessels were constructed in short periods, but it is hard to replace them at the same time in the current situation. The movement of the replacement is not so fast, and the fleet is aging gradually compared with merchant vessels. We observe this phenomenon by the several kinds of graphs.
