HULL FORM DEVELOPMENT OF COASTAL SHIP WITH HIGH ECONOMICAL PERFORMANCE.

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. 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.
