Abstract
Numerous plant construction projects have been executed so far all over the world. Each project normally manages risks of the project for its success. However, overlooking the risks of various projects will enable project management that reflects the tendency of risks. This paper aims to indicate the tendency of risks that may happen during project execution and the problems that are relevant to such risks by analyzing the risk registers of several projects in relation to the characteristics of projects. After classifying risks by cluster analysis, we visualize how the risks are associated with the characteristics of projects by using mathematical quantification theory class III, and then analyze how sensitivity to the risks affects the success of projects.
