Initial assessment of the asset management process of a large industrial plant including probabilistic reliability analysis

Abstract

Engro Fertilizer and Siemens PTI jointly completed a study on the supply reliability situation and on the asset management process in Engro Fertilizer's Daharki (Pakistan) plant. This project complemented earlier projects on, e.g., the overall design and the dynamic performance of the captive generation units in this industrial power supply system. Probabilistic reliability calculations validated that the reliability level throughout the plant is adequate and rather constant. A few individual exceptions are well-known to the operators and covered by explicit processes and measures. Also the asset management process was reviewed from the perspective of the plant's overall reliability performance, and the development plans existing with Engro Fertilizer were confirmed. For certain individual assets or groups of assets, the investigations indicated the need for faster implementation in order to maintain the required risk levels for the plant's operation.

Fault Location Method for Overhead Power Line Based on a Multi-Hypothetical Sequential Analysis Using the Armitage Algorithm

“…The reliability of the functioning of power systems as well as the ability to provide a reliable power supply to consumers depend on the availability of reserve OHPLs, as well as the time required to search for and eliminate a fault on OHPLs [18][19][20]. To eliminate the fault on OHPL, it is necessary to implement organizational and technical measures, which consist of the departure of the repair team to the place of fault and the implementation of emergency recovery work.…”
