ship motion and the effect of disturbance in a short time. The
Joy-stick controller is an easy-handling apparatus for an operator to do the tasks,
especially when he intends to make a parallel shift without making turns and longitudinal
motion in front of a berth. Although it is easy to handle, an operator has to understand
the relation among orders he made, the output of actuators and ship motion.
So, an operator has to be trained to use it with well-understanding.
The Joy-stick is one of the examples of IBS operations.
The other operations, which requires observation of the relation
between ship motion and environment such as berthing maneuver, must also be trained by a
ship handing simulator.
○ Corresponding to emergency
In this section, emergency is defined as the case which all or any
parts of IBS break down. This is an important training for operating the system which has
high ability.
An operator must be trained on the following items;
To understand alarm information
To repair system troubles
To compensate the lack of function(s)
Education through classrooms and training on simulators regarding the
above stated items are required. (Table 2)

3.3 Arrangement of Training Environment
Generally speaking, pre-briefings and post-briefings determine
effectiveness of a training. The same can be said for a simulator training. Knowledge
taught in classrooms is mostly a basic and common knowledge. On the other hand, ship
handling techniques to be trained on a marine simulator are practical items, therefore, in
briefings, explanations must be made on how to combine and apply the basic/common
knowledge to the practical operations. By clearing this point, instructors and cadets can
evaluate results of the training good or not, and cadets can obtain reasonable
understandings.
There is an opinion saying that a training on a simulator is sufficient
by itself, so evaluation for the training is not necessary. Indeed, the simulator training
itself is useful, but the problem is evaluation on the results of the training is left to
cadets' judgement alone. In such a case, a lack of effectiveness and consistency of
evaluation would remain. It is important for the improvement of efficiency of the training
to explain and evaluate results correctly.
Contents of training items must be discussed thoroughly, in order to
obtain effective results. In the
