Abstract |
Many energy and production facilities are operating without clear formal safety requirements, which are considered the base for good process safety management practices. Safety requirements are typically specified during process design based on identified hazard scenarios. This paper proposes a practical framework and methods to systematically synthesize safety requirements based on qualitative and quantitative fault and hazard scenarios. Our aim will be to design a proper safety verification framework which would provide some guidelines regarding the sequence of steps to be taken in the plant for the verification of the safety of that plant. The objective of this paper is to show how the safety verification techniques meet the safety requirements of any production plant. We will clarify Safety Life Cycle and the detailed steps for safety design and verification and also analyze current practices and challenges of safety verification in instrumented/non-instrumented systems. We will also develop possible activity model for safety verification process and will propose safety requirements representation that will facilitate safety verification. Case study of experimental setup is used to demonstrate the proposed framework, which will support safety design and verification. |
