<P>PROBLEM TO BE SOLVED: To provide a maintenance management system and maintenance management program for hull structure capable of effective fatigue and life management of a structure and the maintenance management program, by intending automation of analysis for progress of fatigue cracks and automation of determination of the remaining lifetime, based on the result of the analysis. <P>SOLUTION: The maintenance management system comprises the display 102 for displaying various images; the communications device 101 for receiving the data of encountered marine phenomena via satellite communication acquired on the vessel during actual voyage; the memory device 104 for previously storing the received data of marine phenomena actually encountered, and each fatigue strength data of a plurality of prescribed structural positions and the estimated short-term marine phenomena model data; the remaining lifetime data evaluation means 105b for estimating the remaining lifetime for each structural position, by analyzing the crack progress based on each data in the memory device 104, estimating the crack progress amount of each structural position; and the display control means 105c for displaying on the display 102 by forming the diagnostic card screen 230 that includes the result of remaining lifetime evaluation. <P>COPYRIGHT: (C)2007,JPO&INPIT |
