1-8 痩型船型の新形式船尾形状の開発 : 耐航性能と操縦性能

抄録

In ocean going fine ships such as container ships with high power main engine, it seems almost impossible to improve their propulsive performance to a large extent so far as the conventional stern form is used. The reason is that severe design condition such as a draft restriction, TKM (transverse metacentric height) requirement and propeller tip clearance requirement, restrict the propeller diameter and the stern form modification to a narrow range. The authors developed a new stern form which has better propulsive performance under the above described design, restrictions. This paper describes seakeeping ability and maneuverability of the ship with the new stern form.
