The whole-process operation and maintenance management of compressor sets based on ERP system

Natural gas pipeline systems are becoming complex gradually and there are a variety of old and new assets, especially the key equipments (e.g. compressors) which are diversified in brands and models. Therefore, the comprehensive control is more and more difficult. In this paper, a whole-process operation and maintenance management module for compressors was established in ERP system to conduct the following operation plans, including check and repair optimization, predictive maintenance, preventative maintenance, upgrading, spare parts procurement and energy consumption. Then, based on the whole-process management function of the platform, various activity data of key equipments in the whole life cycle were collected for each unit. The collected data includes historical data, basic information, operation and maintenance records, energy consumption and spare parts consumption. Finally, compressor set BOM technology was developed to analyze reports using system attributes and logical data. Based on that, combinational analysis was carried out on the data of compressor sets in terms of key equipment costs, energy output contrast, energy consumption per hour, comparative cost of manufacturers and economy of each type, so as to optimize equipment maintenance programs, improve equipment reliability and reduce maintenance costs.
