This thesis describes the development of comprehensive algorithms for the analysis and prediction of the transient behaviour of marine electromechanical systems with particular reference to dynamically positioned vessels. The type of oscillatory behaviour studied may be divided into two categories. The first is concerned with predicting response to normal operational conditions commensurate with maintaining on-station duties, involving various load profiles on both thrust and main propulsion systems. The second concerns the prediction of transient behaviour in response to abnormal operating conditions such as that brought about by various system faults. The method of solution is illustrated by reference to simulated results for a practical system for which a comprehensive data set was made available. Digital computer programs are derived for both linear and non-linear time-domain formulations which are designed to be suitable for the analysis of general marine power installations. These programs are based on the developed algorithms which incorporate a full representation of the component parts of the system including rotational and static electrical plant and all relevant drive mechanisms and system controlling functions.
