Replacing or migrating process safety systems, however, carries with it a unique set of concerns and considerations compared to process automation systems.
ARC estimates that the value of the installed base of process safety systems reaching the end of their useful life could be in the neighborhood of $8 billion worldwide. Replacing or migrating process safety systems, however, carries with it a unique set of concerns and considerations compared to process automation systems. Conforming to international safety standards, such as IEC 61511, means that end users must conduct a hazards and risk analysis in addition to allocating safety functions to protection layers. Users should also consider the benefits of remote diagnostics provided by today's intelligent safety instrumented system (SIS) devices and control valves. Learn more about unique considerations in safety system migration and the IEC 61511 lifecycle.
