Abstract

During the operational period on the gas pipeline network there are many potential damage that can result in pipeline failure. The pipeline operators need to perform risk analysis by identifying the damage, determining probability parameters, the consequences of pipeline failures and performing risk calculations so as to know the pipeline network risk profile and the impact for the people, the environment, assets, and reputation of the company. More effective inspections can reduce the risk level by reducing the frequency of future failures, through corrective and preventive action. In general, the purpose of this method is to screen all equipment in an operating unit of a facility to identify areas of high risk, calculate the risk value of all equipment in the operating unit of the product calculation of probability of failure and consequence of failure, determine the priority of equipment requiring inspection based on the calculation of risk, develop an appropriate and effective inspection program and manage the risk due to failure of an equipment and determine the mitigation method to reduce the risk. This study aims to conduct risk assessment that can be used further to minimize the failure that occurs in gas pipeline. The method used is risk-based inspection (RBI) to plan risk-based inspections by comparing probabilities and consequences, arranged in a risk matrix to obtain the level of risk. And the root cause of failure is investigated by using fault tree analysis (FTA) method which to identify the causes of failure in depth, identify weaknesses in a system, assess and propose for reliability or security, to identify the impact of human error, prioritize failure contributors, to identify effective upgrades to the system, to gauge the probability of failure and to optimize the test and maintenance so that the prevention solution can be found. Potential risks that cause the failure are congenital defects, less routine maintenance, operating frequency, easy to dust, material age, difficult to reach the places and less reliable operators. So the cause of the damage is human, equipment maintenance and environment
