In the performance of Long Term Service Agreement (LTSAs) for Integrated Coal Gasification Combined Cycle (IGCC) plants, it has been required that the customer and Mitsubishi Heavy Industries Ltd. (MHI) should work together to perform appropriate Operation and Maintenance (O&M) work and smooth troubleshooting work on both sides to increase the plant operating rate. To this end, it is necessary to share information on O&M-related plans and their implementation results between the customer and MHI so that both sides can perform O&M work together. Furthermore, in order to smoothly perform O&M work in an IGCC plant which is comprised of a large number of facilities, it is also important to manage data for each facility. In conventional power generation plants, however, paper- or Excel-based management of maintenance work and daily operation reports has been conducted. In order to break away from such an analog management, we constructed the O&M Work Basic System (EAM : Enterprise Asset Management) that allows sharing of information on O&M work plans and their implementation results and integration of O&M work between the customer and MHI and management of maintenance plans, their implementation results, operating status, problems and troubleshooting status for each facility comprising the plant. The features of this system and actual use examples are introduced.
