Panelists at a session at the 2019 ARC Industry Forum, Safety Systems: Integrated versus Not? Does It Really Matter?, set out to discuss the pros and cons of the approaches and how they accommodate different risk factors. ARC Advisory Group's Mark Sen Gupta moderated...
One of my first assignments as a newly minted Electrical Engineer was to tend to a triple modular redundant (TMR) safety instrumented system (SIS) on an offshore Gulf of Mexico oil & gas gathering facility. This was back in the 1980s when these systems were...
A safety instrumented function (SIF) within a safety instrumented system (SIS) consists of a sensor, logic solver, and final element. As part of the IEC 61511 global safety standard, these elements within the SIF must be tested during the operational phase of the...
Partial stroke test is one of the viable means to check mechanical integrity of Final Element of Safety Instrumented Function (SIF) loop. Generally, end users struggle on question of credit of PST for improvement in SIL (Safety Integrity Level). IEC 61508 and IEC...
Emerson's Zach Brooks and Steven Kormann described how compliance with National Fire Protection Association (NFPA) with modern burner management and combustion control hardware systems has been simplified. They explored how recently released (and upcoming) standard...
Pressure relief valves (PRVs) are critical safety and equipment protection devices to prevent overpressure conditions. They need ongoing maintenance to assure that they operate as designed for their intended applications. In a Valve magazine article, Lifecycle...
Wikipedia defines a High-integrity pressure protection system (HIPPS) as: …a type of safety instrumented system (SIS) designed to prevent over-pressurization of a plant, such as a chemical plant or oil refinery. The HIPPS will shut off the source of the high pressure...
For manufacturing processes with hazardous substances that are combustible or can cause harm to people and property, flame and gas detection systems are often used as part of the risk mitigation strategy. This 11-minute video, Rosemount Flame and Gas Layers of...
Across the energy supply chain bulk petroleum storage terminals play an important role in managing supply and demand. A critical safety function is to prevent an overfill condition in each of the storage tanks. Another critical function is to manage the pressure...
A safety instrumented function (SIF)'s purpose is to reduce the risk of a specific hazard. For example, an upset condition in an oil and gas production separator may cause a series of SIFs within a safety instrumented system (SIS) to shut in the wells feeding the...
Authors: Enrico De Carolis, Mike Johnson As packaging line machinery has become more sophisticated, it's also become more complex. This increased complexity, coupled with a high number of interactions between operators and machines, increases the potential for safety...
