Development of a New Stern Form for Ocean Going Fine Ships

抄録

In ocean going fine ships such as recent container ships with high power main engine, it seems almost impossible further to improve their propulsive performance to a large extent so far as the convetional stern form is used. The reason is that severe design conditions such as a draft restriction, a large TKM (transverse metacentric height) requirement and an enough propeller tip clearance requirement restrict the propeller diameter and the stern form modification to a narrow range. The authors have tried to break through this wall and, as a result, have developed a new stern form, "Kawasaki SCS (Sophisticated Concave Stern)" (patent pending). This paper describes the development of the stern form.
