ZAP provided engineering and design on a brownfield site.
Projects > Oil and Gas > Pneumatic to Distributed Control System Upgrade
To help our client meet product specification and station uptime requirements at a 50 year old 60MMSCFD gas fractionation plant, ZAP engineered a solution to replace the controls system while drastically minimizing production outages during the upgrade.
Existing control system consisted of local and panel mount pneumatic controllers and paper chart recorders that required extensive maintenance support and operator attendance. A requirement of the upgrade was to allow the work to be performed with minimal plant downtime.
