MATHEMATICAL MODEL FOR THE MANOEUVRING SHIP MOTION IN SHALLOW WATER, 3RD REPORT: MANOEUVERABILITY OF A TWIN-PROPELLER TWIN RUDDER SHIP

Yohei Yoshimura, Hirotaka Sakurai

Open publisher page 23 citations

Abstract

Ship turning and course-keeping qualities change significantly with water depth. In previous papers, the authors presented techniques for predicting maneuvering ship motions in both deep and shallow water for a single-propeller, single-rudder ship. In this paper, maneuverability and its prediction techniques are investigated for a twin-propeller, twin-rudder ship. Results are described for captive model tests and digital simulations carried out for two different ships of this design, and the mathematical model is presented.
