Risk Analysis of Central Java Gas Transmission Pipeline by Risk-Based Inspection Method
During the operational period of gas transmission pipeline was found a potential hazard that could result in pipeline failure. As a consequence, the problem of the pipeline failure happening more and more. Economic and environmental factors, as well as human life, be considered to involve the current challenges as structural integrity and safety standards. Therefore, the reliability of structural integrity and security of gas pipelines under various conditions, including the existence of defects should be carefully evaluated. The results of this study were the steps for setting a Risk Level on any instrument using the Risk-Based Inspection API 581 standard and the subsequent results are recommended as an effective inspection planning by Risk Level and Remaining Life Time.
Study of a risk-based piping inspection guideline system.
A risk-based inspection system and a piping inspection guideline model were developed in this study. The research procedure consists of two parts--the building of a risk-based inspection model for piping and the construction of a risk-based piping inspection guideline model. Field visits at the plant were conducted to develop the risk-based inspection and strategic analysis system. A knowledge-based model had been built in accordance with international standards and local government regulations, and the rational unified process was applied for reducing the discrepancy in the development of the models. The models had been designed to analyze damage factors, damage models, and potential damage positions of piping in the petrochemical plants. The purpose of this study was to provide inspection-related personnel with the optimal planning tools for piping inspections, hence, to enable effective predictions of potential piping risks and to enhance the better degree of safety in plant operations that the petrochemical industries can be expected to achieve. A risk analysis was conducted on the piping system of a petrochemical plant. The outcome indicated that most of the risks resulted from a small number of pipelines.
Experienced knowledge for the description of maintenance packages
The presented work is included in the research theme that specifies some means of capitalization and exploitation of knowledge from experience feedback processes in the context of industrial maintenance management. Our research on it is a more precise definition of the proposed project, built with a problem asking how to handle the management of repair packages. Upstream, the knowledge of various experts are materialized in the form of expert reports. Downstream maintenance wants to quickly repair products based on symptoms or change parts in advance. For this, we propose a methodology by analysing the feedback to improve the response time for maintenance services. This is implemented in the context of a manufacturing traction motors for the railway industry.
