The seaborne cargo volume in Korean trade was 22 million tons in 1970 and has increased to 94 million tons in 1980, with an annual growth rate of 15.5% from 1970 to 1980. Against this backdrop, the Korean government supported Korean shipping companies to expand their fleets in order to back up the rapidly rising trade volume. Therefore, building up a national fleet became one of the key policy initiatives to achieve Korea's economic take-off and ensure its economy stability.
