Burner Management System Upgrade Challenges and Opportunities in Brownfield Installations
by Mike Scott, P.E., CFSE, aeSolutions Founder & Paul Gruhn, P.E., CFSE
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 organization to further maximize savings. Actual experience doing this on repeat BMS projects indicate the level of overall savings can be as high as 75% on the safety lifecycle, 70% on the control system design and integration, and 35% on the operation and maintenance activities. The combined overall savings are roughly 60%.
