Chevron Bangladesh is the largest natural gas producer in Bangladesh, who is supplying approximately 50 percent of Bangladesh’s natural gas consumption. Through subsidiaries, Chevron Bangladesh produces natural gas and condensate from three fields at Bibiyana, Jalalabad and Moulavi Bazar, in northeast of Bangladesh. Bibiyana Gas Plant is located at the Bibiyana field in Block 12 of the Habiganj District, Sylhet Division. The plant is approximately 150 kilometers in the northeast of Dhaka.
The existing gas plant had four gas processing trains. In order to process increased natural gas volumes from the Bibiyana field, the Bibiyana Expansion Project (BYX) was launched to add two new gas processing trains with additional development wells and an enhanced gas liquids recovery unit.
Chevron Bangladesh was looking for a process automation system for which operations can control the plant safely at its optimum performance with minimum downtime and keep the process within the limit of safety operation. Yokogawa offered CENTUM VP as the Distributed Control Systems (DCS), and ProSafe-RS as the Safety Instrumented Systems (SIS) and the fire and gas system(FGS), through the integrated Human Interface Station (HIS) between CENTUM VP and ProSafe-RS. Yokogawa (Thailand) Limited received a purchase order to replace Allen Bradley PLCs at the existing four gas processing trains with CENTUM VP and ProSafe-RS, and install CENTUM VP and ProSafe-RS at the two new gas processing trains. Yokogawa Engineering Asia Pte. Ltd. provided the engineering work and Yokogawa India Limited commenced the site activities for erection/commissioning and startup support to complete the project.
Yokogawa’s scope of work includes engineering, supply of CENTUM VP, ProSafe-RS, the DPharp (EJA-E) pressure/differential pressure transmitters, the YTA temperature transmitters, the ROTAMASS Coriolis Flowmeters, the Rotameter Variable Area Flowmeters, the Plant Resource Manager (PRM) asset management package, the Unified Gateway Station (UGS) subsystems integration package, the Advanced Operating Graphics (AOG) consultation and implementation for HMI graphics, Network Security Solution service, Alarm Management System, CCTV package, Data Historian, Vibration Monitoring System, and Erection and Commissioning/Startup support.
