Study Supports Wireless In Capital Projects, Emerson Says

Emerson Process Management has unveiled quantified results and other findings of two independent real-world greenfield projects that recommend wireless infrastructure be a key component of all new projects.  In one use case, JDI Contracts applied Smart Wireless technology to applications in a new process plant for a major U.S. chemical manufacturer; in the other, Emerson modeled a hydrotreater capital project. Economics, efficiency and other advantages made the case for wireless with both JDI and Emerson.

JDI worked with a major EPC and end user to study the project impact of wireless.  They compared engineering, construction, startup, and overhead costs for approaches using wired HART, wired bus technologies, WirelessHART, and combinations of each.  Wireless was used for non-safety, low speed control and monitoring, amounting to about 25% of the total points.

With each paradigm shift -- wireless being the latest -- plants realized savings and became smarter through simpler engineering and construction, flexible start-up, faster deployment and project completion, and changing automation needs.  For the use of Smart Wireless on 25% of points, overall plant engineering, construction and startup savings were about 10% of considered costs as compared with wired HART; for the bus installation, wireless savings were on a par with wired busing. Although not quantified, other considerations of flexibility and schedule impact were deemed very important in each approach.
