Refinery Uses Wireless Network to Improve Plant Visibility, Safety
IPS was awarded the turnkey contract to supply a complete “offsite” solution to the Milford Haven refinery. Offsite operations are crucial in the production process, providing handling and storage for high quantities of gas or liquid in the form of tank farms and terminals.
Extronics worked with IPS to provide significant improvements in the efficient operation of these offsite facilities at Milford Haven in Zone 1 and Zone 2 related hazardous areas.
IPS required Extronics to provide a robust and cost-effective measure to deliver work scheduling and position status feedback to operators, in real time, on more than 1,500 manual valves involved in the offsite operations to be displayed on a process mimic.
On Extronics’ recommendation, an intrinsically safe and explosion-proof WLAN was installed. This enabled Windows Mobile rugged PDAs and RFID tags to be used together by operators to enter the status of the valves and feed the information back to the process mimic.
By using the wireless network, IPS was able to offer an economic and secure solution for Total’s extreme environments and Zone 1 and 2 hazardous areas throughout the Milford Haven plant.
