While the oil resoures have become 60% among the overall cost, the propulsive energy which is used to rotate the propeller have been consumed as the about 32% against total shaft horse power which is made in the marine main engine. We consider that the using fuel oil must be the saving of the energy converting from the thermal calorific fuel oil energy to the rotating energy of propeIler. So, here we quantitatively clarifired for saving energy of main engine of T/V Kakuyo?Maru during 1990 to 1998. Due to advancing of the marine fouling animals of the hull bottom and the propeller blades, the propulsive coefficient have been deteriorated． In this study, it is recognized that fuel consumption value increases up until 22.24% and SM increases large up until 9.4～16.4% for the second half-year of each year.
