Abstract

Quantitative Risk Assessment (QRA) that had been used in the industry before is known to be static and a dynamic risk assessment is form using real time data and Bayesian theorem where the assessment is updated with near misses or accident that had occurred. Research has proven that dynamic approach in risk assessment can predict the incident that occurred in BP Texas refinery. Steps in conducting the dynamic risk assessment are scenario identification, prior function calculation, formation of the likelihood function and posterior function calculation. A calculation tool using Visual Basic (VB) software is develop base on the function and is validated with published data. Result shows that it is possible to develop a tool for this assessment using coding by VBA software. Dynamic failure assessment also manages to prove that risk of failure of component also increasing over time.
