Abstract
It becomes a more and more common practice to build facilities bigger and more integrated in an effort to optimize the process within limited resources and spaces. As the capacity of facilities increases, so does the flow rate and pressure. This in turn leads to a high consequence of accident. Not only are these facilities vulnerable to leakage because of their high pressure, but also subsequent fire and explosion can be threatening. For these reasons, there is an urgent need to come up with solutions to assess and minimize the damage from an accident. The Quantitative Risk Assessment(QRA) is one of the most efficient ways to solve problems on pressurized pipelines. The QRA can be re-enforced by applying reduction factors. In this study various types of accidents in a pressurized pipeline were evaluated. The damage from accidents were computed, then. Finally the reduction factors were very effective to decrease consequences of high pressure pipeline accidents.
