RECENT DEVELOPMENTS IN ENERGY SAVING TECHNOLOGY FOR SHIPS AND THEIR APPLICATION TO VLCCS

This article summarizes energy-saving technology developed for ships designed by Mitsubishi Heavy Industry, Japan, and applied to the VLCC NISSEKI MARU delivered in April 1988. The developments dealt with the reduction of ship resistance, the propulsive performance, the machinery plant and the general navigation system. They involved hull form modifications; a reduction in hull weight; reduction in air resistance; the use of a large, slow propeller; improvements in propeller material; stern appendages; contrarotating propellers; an engine combustion control system; a waste heat recovery plant; and the Mitsubishi SUPER TONAC navigation control system. Incorporating these developments, the NISSEKI MARU delivers high propulsive performance, representing fuel oil consumption of less than 50 tons per day.
