      The life and working conditions of a machine depend on maintenance-repair activities. Marine diesel engines, together with the heart and main drive system of the ship, carry many risks due to their size during maintenance. These risks can cause serious loss of compensation if they occur. In this study, maintenance and repair activities carried out in two stroke marine diesel engines were examined in terms of risk magnitudes and the most risky maintenance-repair activities were tried to be determined. For this purpose, the Fuzzy Analytical Hierarchy Process (FAHP) method is used in the Multi Criteria Decision Making (MCDM) methods, which transforms the qualitative information obtained from the experts into the quantitative form. The 46 identified maintenance-repair studies were compared with the Buckley and Chang approaches and the risk weights were determined for the most frequently used FAHP methods in the literature. It is thought that the results obtained will shed light on future work to reduce risks by eliminating losses.
