Abstract
Currently an increasing number of modern ships is equipped with podded propulsors. Advantages are an improved propulsive efficiency, an improved manoeuvrability of the ship and the possibility to use a diesel-electric propulsion plant and a decrease of vibrations in the stern of the vessel.
Besides application to cruise ships the pod concept is nowadays also applied to other ship types and to vessels of a higher speed range. Major benefits are normally obtained, but still areas of special attention exist. Due to the possibly large steering forces, large steering-induced heeling angles can occur. Additionally, the directional stability of ships with pods tends to be less than comparable ships with conventional propulsion.
This paper describes the aspects of application of pods from a manoeuvring viewpoint. In particular the differences in use compared to conventional propulsion and shallow water effects are highlighted.
