INTECH’s Hot Cutover Expertise Enables Vastly Superior Process and Safety Control in West Africa
INTECH Process Automation Nigeria Limited successfully executed a hot cutover upgrade project at a dehydration plant in West Africa enabling vastly superior process and safety control at the facility.
The client, one of the major oil and gas companies in the world, boasts a long and successful presence in Africa. INTECH was awarded this project based on a burgeoning list of excellently executed automation projects with the client as well as years of successful business operations in the African continent.
The dehydration plant was set up to remove water content from the crude oil before shipping to mid-stream and down-stream facilities and customers. The said facility has evolved over time starting from a crude oil heater and a water knockout vessel to having extended processes of multiple heaters, chemical injection and separation units. Owing to this evolution, the control and safety systems are split into various packages (WashTank PLCs, Ground Flare PLCs and Gas Tech PLCs) and main process control PLCs.
INTECH team proceeded to firstly split the main process control PLC, which was a single PLC5 based control, into separate Process Control PLCs and the Safety Shutdown System PLCs and as well as to upgrade the PLC5 based system to full ControlLogix based system. Secondly the new object functionality was to be implemented into the packaged PLC systems, essentially changing the way operations were performing their day to day functions on the HMI and making them consistent for all PCS, SSS and Package systems.
The biggest challenge was that the client could not afford any downtime and therefore the system had to be kept live at all times. INTECH was therefore to perform a Hot Cutover of the main PLC into a split PLC and SSS. INTECH came strong in the ICSS design and package systems engineering phase conducting a successful FAT. Then exhaustive planning works and SAT preparations provided excellent stepping stones in planning and executing the Hot Cutover of the main PLCs into a split PCS and SSS. The project lifecycle was immaculately executed; to our client’s immense satisfaction; from Engineering phase to FAT. SAT was done on the Dehydration Site followed by the Hot Cutover of the Safety Systems; upgrade of the package PLCs, converting the PLC5 based Process Control IO system to ControlLogix IO systems and decommissioning activities.
The baseline FAT-ed package system applications became online smoothly when downloaded to their processors and not only were the client’s alarm management objectives achieved but to its utter delight, the solution enabled vastly superior historical trending and monitoring than before. The INTECH project team received raving reviews from the client and was lauded for its strict adherence to the timelines as well as the procedures and plant operating philosophy.
