Developing Tolerable Risk Criteria for Gas Transmission Pipelines

After completing an extensive risk assessment stage, PGPB’s Risk Management Team was ready to move towards Risk Management philosophy. Comparing PEMEX’s algorithm with the typical values of the industry enabled the risk assessment approach adopted in PGPB. As a result of a comprehensive study that gathered several of the users of the same analysis tool, an optimised and normalised algorithm was obtained to support the risk assessment programme and comply with the company’s policies.The risk assessment stage included more than 1,700 kilometres of LPG pipelines and 3,500 kilometres of natural gas. This stage was granted as final until consistent risk values were achieved in every segment section. To move into the Risk Management stage a comprehensive study was performed to define tolerable risk criteria for PGPB pipeline network.Copyright © 2000 by ASME
