Abstract
In this paper, we investigate educational effect on delivery type experimental education of maintenance engineers. Experimental lecture time is about 6 hours. Experimental content is the principles of corrosion and corrosion protection. Instruments was used which was improved to the micro scale. Experimental lecture text was produced what can be easily understood only in presentation materials. In this lecture, engineer of three fields (ground, underground, floating facilities) participated. The total number of participants was 263 people. Expertise of its people were mechanical, electrical and civil engineering. It was people with a variety of experience to veterans from rookie. The results of questionnaire survey, understanding of basic knowledge of corrosion was increased to more than 95%. Micro-scaled experimental instruments is better to use a few people than one person. These instruments was found that the education effect is increased enough. Although experimental lecture were carried out 6 hours, participants did not go to sleep.
