Exploring the concept of taking proof test credit for an unplanned shutdown in order to delay a Safety Instrumented Function (SIF) proof tes

Is our industry addressing the problems facing it today? We idealize infinitesimally small event rates for highly catastrophic hazards, yet are we any safer? Have we solved the world’s problems? Layers of protection analysis (LOPA) drives hazardous event rates to 10-4 per year or less, yet industry is still experiencing several disastrous events per year. If one estimates 3,000 operating units worldwide and industry experiences approximately 3 major incidents per year, the tr
