An Analysis of Starting Points for Setting Up a Model of a More Reliable Ship Propulsion

This paper considers the important requirement for ship propulsion necessary for its immaculate operation, since any failure can endanger the ship and render it useless. Particular attention is given to the failure of auxiliary engines that can also seriously jeopardise the safety of the ship. Therefore the paper presents preliminary investigations for setting up models of reliable ship propulsion accounting for the failure of auxiliary engines. Models of most frequent implementations of electrical energy generating systems are defi ned, analysed and their infl uences assessed. Based on simulation results, analyses of the models and data from relevant data bases on ship machinery arrangements and failures, possible solutions for improving ship propulsion reliability are presented. An analysis of proposed possibilities leads us to the conclusion that it is necessary to defi ne a new model for reliable ship propulsion including auxiliary mashines
