MATHEMATICAL MODEL FOR THE MANOEUVRING SHIP MOTION IN SHALLOW WATER

Yohei Yoshimura

Open publisher page 41 citations

Abstract

Maneuvering behavior significantly changes according to water depth. An examination of safety in harbor navigation therefore requires clarification of the characteristics of ship motion in shallow water. Following the full-scale trials of the ESSO OSAKA, many model tests were performed to observe the characteristics of hydrodynamic forces acting on hull or rudder. These hydrodynamic data are insufficient, however, for the prediction of maneuvering motion in shallow water, and more theoretical approaches have been desired in addition to experimental data. In this article, the predicting techniques are investigated based on the well-known MMG's mathematical model.
