dc.description.abstract | This report is a safety analysis of the Isle of Wight waste plant in England. Energos AS prepared a Hazard and Safety analysis in connection with this project. In the analysis Energos AS has defined Safety Integrity Level (SIL) requirements for SIF. This report verifies the fulfilment of the SIL requirements, and recommends design modification for the functions. Two quantitative requirements and one qualitative requirement must be fulfilled to obtain the given SIL. This report verifies only fulfilment of the quantitative requirements. It is important to be aware that the qualitative requirements are the foundation of the SIL analysis, and MUST be fulfilled to achieve the given SIL for instrumented safety functions. Chapter 3 gives the analysis of 20 ESD actions. Typical ESD actions are: Start hydraulic pump, Close guillotine and Stop air fan. Chapter 4 presents the analysis of 12 hazard case functions. The hazard case functions comprise ESD actions from Chapter 3, and single ESD components. The composition of ESD actions for each hazard case function is defined by the safe state for the hazard case. Chapter 4 will first present the analytical result from the original system together with the requirements, which must be fulfilled, to obtain the given SIL. Afterwards some design modifications are suggested, and new architecture requirements are given to fulfil the SIL requirements. | nb_NO |
