🚀 Introduction
The role of a process safety engineer in 2025 is more critical—and more complex—than ever before. With industries such as oil & gas, petrochemicals, pharmaceuticals, and renewable energy embracing digitalization, software tools have become essential for accurate analysis, risk mitigation, and regulatory compliance.
Gone are the days when spreadsheets and hand calculations were enough. Today’s process safety professionals need smart, reliable, and integrated tools to handle the increasingly sophisticated demands of HAZOP studies, SIL analysis, QRA, dispersion modeling, and emergency planning.
