Focus on the Process in Your Safety Requirements Specification
A safety requirement specification (SRS) for a safety instrumented system (SIS), as part of the IEC 61511 global safety standard [from the exida blog]: …incorporates all the analysis done during the Risk Assessment, HAZOP [hazard and operability study]/PHA [process...
Moving Towards Inherently Safer Plants
In the early days of social networks and even for some process manufacturers and producers today, IT departments blocked these social networks including YouTube. I recommended that engineers point to sites such as the U.S. Chemical Safety and Hazard Investigation...
Embracing Safety Requirements Specifications
The Institute of Measurement and Control is hosting the Functional Safety 2016 conference this week in London. This conference seeks to engage practitioners from a wide variety of industrial sectors who have responsibilities in any functional safety lifecycle phase to...
Safety Logic Solver Validation on Logic Updates
The global safety standard IEC 61511 Functional safety - Safety instrumented systems for the process industry sector describes the validation process. The objective of the requirements of this clause is to validate, through inspection and testing, that the installed...
Testing Valves in Safety Instrumented Functions
Safety instrumented systems are a critical part of process manufacturers and producers overall process safety management in protecting personnel, environment, equipment, property, reputation and image. In an Offshore Engineer article, Safety Instrumented Function loop...
Midstream Oil and Gas Sector Trends
Natural gas processing facilities, terminals, pipelines and other forms of petroleum product transport are part of the midstream oil & gas sector. Operating these midstream operations safely, efficiently and reliably has proven to be an ongoing challenge....
Process Automation Nextgen Leaders
Given the important role that process automation plays in the products that process manufacturers and producers bring to the world, it's important to have continuity in leadership. Each year, Control Engineering and Plant Engineering magazines recognize Engineering...
SIS CHARMS in DCS and SIS Integrated Solution in DCS Modernization Project
Emerson's Janka O'Brien, with support from MC Chow, teamed up with Robert Ancrum, the SIS Technical Authority for a major Midwestern U.S. refiner, to tell a story of a control system and SIS modernization project. Their abstract: This session is to discuss DCS...
Verification in the IEC 61511 Safety Lifecycle
I received a great question about the application of the IEC 61511 safety lifecycle. The person noted that a question was raised after the safety integrity level (SIL) study and safety requirements specification (SRS) had been performed. The question is about the...
Control Valve Suitability in Safety Applications
Sometimes an email exchange turns up something developed years ago that still has great value. So is this case with an article I received as an attachment on final control elements and their suitability in safety instrumented functions (SIFs), a.k.a. safety loops. The...
Managing the Safety Lifecycle
Process safety revolves around managing the risks of your production process throughout the life of your plant, mill or production facility. The international safety standard, IEC 61511 (Functional safety - Safety instrumented systems for the process industry sector):...
