Crew reductions require a thorough understanding of the reliability and maintainability of ship systems if economic gains are to be made. This was an investigation of reliability of ship systems on 16 motor cargo ships and 12 motor tankers over a 200 ship-year period. Failure was defined as an unexpected deterioration of machinery performance, requiring additional repair work besides the regular routine maintenance work. Stress was laid on the general character of failure and its frequency of occurrence in relationship to maintenance, as the first approach to reliability engineering. This study learned how many man-hours are required to meet the need of maintenance and failures in ships' systems. Therefore it provides a guide to where further research is needed to improve economics through more reliable equipment.
