by aeSolutions Technical Team This paper will discuss how quantitative methods can be utilized to select the appropriate Safety Integrity Level associated with Burner Management Systems. Identifying the required amount of risk reduction is extremely important especially when evaluating existing legacy Burner Management Systems. Selection of an overly conservative Safety Integrity Level can have significant cost impacts. These costs will either be associated with increased Sa

by aeSolutions Technical Team ​ A two‐prong templatized approach to multiple brownfield burner management system upgrades can result in significant cost savings. The first step requires coming up with an equivalent design for the safety instrumented burner management system following the ISA 84 safety lifecycle , as allowed in current NFPA standards. The second step utilizes a templatization approach for multiple units with common functionality that will allow an organizatio
