For process manufacturers and producers with safety shutdown applications, local control panels are often installed to provide visibility and control actions to operators locally out in the process area. Actions can be taken at these panels to initiate an emergency shutdown. I caught up with Emerson’s Riyaz Ali about how these local control panels work […]
Imagine 30% of a country’s energy supply relying on two safety shutdown valves to flow natural gas and liquid condensate safely from offshore oil & gas production platforms to an onshore processing facility. It’s critical that the valve actuators reliably perform their function to close the valves when a shutdown command is issued by the […]

I’d like to thank the ISA Kuwait staff and encourage readers in this […]
InTech magazine has a web exclusive on the importance of safety valves in a safety instrumented system. The article, Valve failure: Not an Option, describes methods of implementing partial stroke testing (PST) to reduce the probability of failure upon demand, average (PFDavg). For those not familiar with a partial stroke test, I found this definition: […]
