| Abstract |
Most formulations of mathematical modelling of ship manoeuvres in shallow water discussed in literature are based on the expressions for the deep water case. Several usual and unusual phenomena occurring during manoeuvres at limited under keel clearances (10% to 50%) are not considered. A tabular model for the hull forces is proposed, taking the shallow water condition as starting point, with the intention to cover wide ranges of kinematical parameters so that a great variety of manoeuvres can be simulated. The implementation of the mathematical model is based on captive model tests with 4 m models of the tanker Esso Osaka and a fourth generation container carrier. The experimental program consists of well-known, classical PMM test types combined with alternative tests. Guidelines are given according to the influence of the selected test parameters on the hydrodynamic coefficients. |
