Abstract Marine transportation is a crucial activity in the development of human civilization. Following the track of the history, the focus has been shifted not only on the safety of vessels, but the protection of the ocean environment and the keep of the working space and accommodation for crews. Therefore, the Port State Control (PSC) is getting popular around the world. This paper is trying to introduce the origin, contents, working scope of the Port State Control, and summarize the PSC executive condition of foreign countries, the local area MOU (Memorandum Of Understanding) organizations, the international marine organization, and the regulations of Port State Control. Based on the concept and spirit of Total Quality Control (TQM), i.e. PDCA (Plan, Do, Check, Action), the Port State Control (PSC) could be managed smoothly and efficiently, for either the Port State Control Officers (PSCOs) or the marine transportation. In this paper, we introduced the present condition of PSC of our country and the concept of PSC. And an ideal PSC flow chart has been proposed for the Kaohsiung Port and Taiwan, ROC. This thesis is proposing several substantial suggestions for the PSC in Taiwan, ROC. For fulfilling the obligations as a member of the earth village, I do hope these suggestions could be a useful reference for PSCOs in the country.
