| Abstract |
An overview of results of systematic captive manoeuvring test series with a container carrier model and a tanker model above a solid bottom as well as above and in simulated mud layers is presented. The effect of under keel clearance on linear manoeuvring coefficients and dynamic stability parameters is discussed, with emphasis on very small and even negative values referred to the water-mud interface. Controllability and manoeuvrability appear to be affected particularly by the influence of water depth on the lateral force due to yaw, as at very small under keel clearance the centrifugal inertia force is completely compensated by a hydrodynamic centripetal force. |
