Abstract
The air separation plants in the POSCO's Gwangyang Steel Works require high standard on quality as well as reliability as they have to continuously supply essential utility gases as oxygen, nitrogen and argon. And the plants are in the category of high pressure gas systems by the regulatory guidelines, which signifies that they have to maintain utmost level of safety. As an effort to systematically understand and calculate the risk potentials in the air separation plants, risk assessments have been performed on a phased approach: qualitative and followed by quantitative POSCO has chosen to use hazard and operability study and fault tree analysis to satisfy the requirement. As a result, the risk assessment team has identified number of safety and operability related findings. With importance of each and ever findings calculated, a priority list for what/when to do for them could have been presented on a balance fashion.
