CHALLENGES IN THE DEVELOPMENT OF A RISK MANAGEMENT SYSTEM FOR NATURAL GAS AND HAZARDOUS LIQUID PIPELINES

摘要

This paper covers some challenges encountered in the development of a risk management system for onshore natural gas and hazardous liquid pipelines. This system is based on the premises of PID - Petrobras Pipeline Integrity Management Program that defines rules for risk calculation and risk mitigation actions to be carried out whenever risk is above a level defined as tolerable. Commercial risk assessment software was customized to PID and is being upgraded with an algorithm able to assist in optimizing risk mitigation projects based on proposed scenarios. This study presents the challenges and benefits of implementing such a risk management system on a prototype pipeline system and the difficulties faced along the development of a scenario optimization algorithm, which is still in progress at the date of its publication.
