Sažetak
The first part of the paper presents a survey of approaches to maintenance in the last thirty years. Here is presented a structure of maintenance costs and maintenance concept adjustment and design (MA-CAD) of the ship machinery (propulsion engine), which provides the required safety level and the lowest costs in the life cycle. Improvement and extension of the MA-CAD method can be achieved by an analysis of the most frequent of the propulsion engine significant (critical) items that fail mostly in operation, by designing maintenance intervals and planning the spare parts quantity. A diesel-engine propulsion system with gearbox has been chosen for the research. The data about failures and maintenance activities at the propulsion engine breakdown in a seaway within the period of thirteen years are obtained from the engine s log book. The critical items that fail mostly in operation are defined by an analysis of breakdowns (registered failure cycles). The critical components include the exhaust valve, the injection valve and the fuel pump. The most jeopardized item of the propulsion engine is the exhaust valve with the highest failure rate. By application of the mentioned method we obtain the model for the maintenance concept adjustment and design. The suggested model consists of two parts (a new MA-CAD): the ship and the office. The engine machinery behaviour is monitored aboard the ship (failures and maintenance functioning) and the data are sent to the office. On the basis of the data, the office performs the analysis and adjusts (models) maintenance concept.
