A compilation is given of operating statistics for tankers in the 50,000- to 500,000-ton range. These statistics are plotted for construction cost, insurance cost, crew cost maintenance and repair cost, fuel consumption, and overhead cost all versus total deadweight. Actual operating time of tankers in the 200,000-ton range is limited to the Tokyo Maru ( 150,000 tons ) and the Idemitsu Maru (206,000 tons ). However, these statistics are also based on the expected operating costs of the 312,000-ton tankers presently under construction, and the 500,000-ton tanker being designed by Mitsubishi Heavy Industries, Ltd. In Appendices I and II, a proposed 1,000,000-ton tanker is compared with the Idemitsu Maru for two trade routes. The objective of this comparison is to find the maximum permissible construction cost of the megaton tankers by using the required freight rate of the Idemitsu Maru as an economic goal.
