36th WEGEMT Summer School on Manoeuvring and Manoeuvring Devices

This publication represents a series of lecturers' papers, which were presented at a five day event entitled Manoeuvring and Manoeuvring Devices. The event was hosted by INSEAN, Rome, from 14th to 18th May 2001. The manoeuvrability of ships represents a particular challenge that is influenced by a great many factors. One of these factors are the devices, which have to produce the forces for course correction, course keeping and manoeuvring. Steering units are subdivided into "ACTIVE" units, where active energy is used to generate the steering forces, and "PASSIVE" units, which use external energy sources like a conventional rudder positioned behind a propeller. The first part of the paper deals with active steering units and propulsion units, in particular steerable rudder propellers. The distinguishing feature of a steerable propulsion system is its ability not only to convert the engine power into thrust but also to make this thrust available in all directions by rotating the propulsion unit 3600 around. Nowadays the importance of Computer Fluid Dynamics (CFD) increases also as a tool to analyze special problems of steerable thrusters and to point out measures to improve these systems. The second part of the paper focuses the advantage of applying CFD-methods to analyses the performance of a modem propulsion system such as SSP. Before going in detail, some examples for active steering devices will be presented.
