In the 1960s and 1970s, some Western economists asserted that the bigger the vessel, the better it will operate. At that time, many owners competed to order large and very large ships, especially tankers. From 100,000 DWT in the 1950s to 200,000 DWT in the 1960s, by the 1970s the world’s largest tanker reached 470,000 deadweight tonnes.
