The purpose of this research is to create an expert risk-based piping system inspection model. The proposed system includes a risk-based piping inspection system and a piping inspection guideline system. The research procedure consists of three parts: the risk-based inspection model, the risk-based piping inspection model, and the piping inspection guideline system model. In this research procedure, a field plant visit is conducted to collect the related domestic information (Taiwan) and foreign standards and regulations for creating a strategic risk-based piping inspection and analysis system in accordance with the piping damage characteristics in the petrochemical industry. In accordance with various piping damage models and damage positions, petrochemical plants provide the optimal piping inspection planning tool for efficient piping risk prediction for enhancing plant operation safety.

현재의 유지보수 시스템은 고정 설비 및 회전기계의 유지 및 보수에 대한 명확한 기준이 제시되지 않고 있으며, 고장이 발생되더라도 근본적인 원인분석 없이 교체 및 수리가 이루어져 더 큰 사고를 초래할 수 있는 환경이다. 따라서 본 연구에서는 예방보전을 통해 사전에 점검하고 유지 보수할 수 있도록 신뢰성 중심의 유지보수 시스템의 절차를 개발하였고, 향후 유지보수에서 설비의 고장형태에 따라 문제 발생 설비를 집중 관리함으로써 중대산업사고의 발생을 사전에 예방하고 관리할 수 있는 절차를 제시하고자 하였다.

Nowadays new water supply projects have been on the decline as the water-power constructions have saturated, which means that the existing power equipment have slowly aged and they require more efforts to maintain the system performance. An effective asset management method of power equipment has become a great necessity from both economical and technical aspects. To be balanced, the asset management should look into all three parts: management, engineering, and information. The purpose of this paper is to study a Risk-Based Maintenance (RBM) matrix method through the deterioration evaluation algorithm for an efficient reliability assessment of oil-immersed power transformers by considering both asset management and technical evaluation. Make use of this result, the equipment will be decided to be replace or repair otherwise on service.
