Support for engineers in SIL rated processes

16 September 2014

The IEC industry standards detailing the safety performance requirements for hazardous operations have been widely adopted by many industries (IEC 61508 and IEC 61511). However, the requirement within high integrity industries, such as the oil and gas sector, to further quantify levels of compliance within these standards has led to the implementation of the Safety Integrity Level (SIL), another measurement of the reliability of protection systems in hazardous processes.

 


Elfab rupture discs and burst detection assemblies contribute to these systems. Rupture discs have become an increasingly popular method of pressure relief in modern process plants with ever-increasing safety standards and environmental considerations. The need for reliable yet cost-effective detection systems to indicate when a disc has functioned has also become a pressing requirement.

 

This has led disc manufacturers and customers alike to seek increasingly advanced systems that provide reliable protection. In response to customer requirements Elfab is now able to assist engineers working within stringent SIL rated conditions.

 

Knowing suppliers comply with such requirements enables users to specify more suitable pressure relief and associated detection devices into their high-risk installations, where the reliability of the safety system is paramount. Using generally recognised models for risk assessment and risk reduction, engineers are now finding this an effective way to improve a systems overall safety.
