Assessing gas turbine safety and efficiency: A comprehensive analysis of HAZOP, LOPA, and SIL methodologies

Abstract

This work has been conducted at the Roude Nouss gas compression station with the aim of managing the risks associated with the “PGT25 gas turbine” section, assessing the Safety Integrity Level (SIL), and optimizing the safety and performance of the facilities. The findings of the simulation prove that a risk reduction factor of 32 has been achieved for scenario 1 through the implementation of a Safety Instrumented System at SIL2 level, which reduces the frequency of undesired events to 9.86×10⁻⁸ per year. Regarding scenario 2, a risk reduction factor of 100 requires the establishment of a safety barrier of the IPL type, resulting in a reduced event frequency of 9.98×10⁻¹⁰ per year. On the one hand, scenario 3 reveals a risk reduction factor of 32, thereby justifying the adoption of a Safety Instrumented System at SIL2 level, with a reduced event frequency of 9.85×10⁻⁷ per year. The simulation conducted by using the ALOHA software highlights the risks associated with an accidental release by illustrating the potential extent of environmental impacts and threats to human safety.
