外航船実態調査

Abstract

In these years, Port State Control has been done strictry for purposes of expelling sub-standard vessels. But there are still many sub-standard vessels in the world and some of them causes the terrible oil pollution by its casualties. We researched on the state of 1703 oversea vessels which came into Japanese ports during March, 1997 and found those vessels, which were commanded by captain from East Europe and Asian communist countries, have problems. Small vessels such as less than 5, 000GT have also problems.
