In order to improve an economical situation of a coastal transportation, to develop a hull form with high performance for saving a fuel oil consumption is very important. The research project concerning the hull form development of the so-called 999G.T. type coastal oil carrier was carried out from 1984 to 1985. This report shows the research procedure and the results of model tests. The outline of the study is as follows. (1) The prototype was sellected as the base of hull form improvement. (2) The first stage of hull form improvement was made by using the proportion of hull, which showed the minimum operating cost among the some combinations of principal dimensions. (3) The second stage was made by modifiying the shape of fore body and by adding bulbous bow. In this stage, the statistical analysis method based on the wave-making resistance theory and the type ship method were applied. (4) In the third stage, the thrust deduction factor was improved by using the calculating method on the propeller-hull interaction. (5) The final stage was made by adopting the low speed propeller with large diameter and stern bulb shape. As the result of this study, the remarkable reduction of the engine power had been achieved. Besides the items mentioned above, the evaluation about the vibratory forces induced by propeller and the economical advantage by making use of the ship with a newly developed hull form are also shown in this report.
