Maintenance Concept Adjustment and Design

The paper presents a method for adjustment and design of the ship machinery system maintenance concept. The method begins from an installed component to the risk analysis, namely from the failure mode to the maintenance concept. The system decomposed into units and further to the level of installed components, which are classified as the type item of a component. The data about failures and maintenance activities at the ship machinery breakdown in a seaway are obtained from the engines log book. The failure mode1 analysis includes specification of the type of components, the sub-type and the components itself. The risk analysis comprises the definition of the upper and the lower risk criterion, as well as the definition of a risk index. For each significant component with a risk index found to be unacceptable or undesirable, an efficient maintenance policy needs to be adopted. Improvement and extension of the MA-CAD method can be achieved by an analysis of the most frequent of the ship machinery significant items that fail mostly in operation, by designing maintenance intervals and planning the spare parts quantity.
