ABSTRACT
A ship operation system is now in transition corresponding to the
advancement of electric technology and computer technology.
In a new operation system, many of the tasks would be executed by a
computer system. The ability required of a human operator is to operate the newly
introduced system correctly as well as conventional operation ability.
In this paper, a human operator's function which is required in the
Advanced Navigation System is discussed compared with the human function in the
conventional navigation system. And also discussion is made on the ability necessary to
execute the function and on the training to bring up the ability.
Moreover, in order that the Advanced Navigation System which is
currently developing could realize a sufficient supporting system for an operator, its
final image is indicated. On principle, a ship operation system should be designed by an
operator.

1. INTRODUCTION
It is said that more than 80% of the causes of marine casualty are
human errors according to accident analysis and following items are represented results in
Reference 5. Paramore et al.(1979)
○ Over 60% of grounding casualty within harbor and harbor entrance
area are caused by failure to maintain positions resulting from an incorrect assessment of
wind and current effects.
○ Many accidents caused by position measuring errors in narrow water
channels happened.
From this report, we can understand that many accidents are led by
human errors. Reliability of total ship handling system including human must be improved
by compensating the tasks where human could make mistakes. Although compensation for
hardware such as double hull can be effective to minimize the damages of accidents, more
reasonable and effective compensational way is to develop the ship handling system that
prevents accidents.
The modernization of handling apparatus is proceeding in northern
European countries. This system is
