Daniel Jarvis and Ashley Holt have recently finished phase 1 of the installation and commissioning for project Shell CPUG PWRI Metering & Leman AC MSC Integration.
Phase one of I&C consisted mainly of the AC MSC integration, hardware changes to the existing AK metering panels and DCS end-to-end testing. The scope of this project included the integration of 4 metering stations into the existing Leman & CPUG TruST MSC:
Leman PWRI – New flow computer application
AK Leman Fuel Gas – New flow computer application
AC Gas Export – Existing flow computer application
AC Fuel Gas – Existing flow computer application
Shell had requested that the existing AC metering panel is to be tied back to the TruST MSC, as the current AC supervisory system is now obsolete. The AC system consists of two existing metering stations, AC Gas Export and AC Fuel Gas, which are now successfully tied back into TruST. In addition, the Gas Chromatograph is now tied back into TruST, which had previously lost communications to the existing system and was not in operation.
Integrating the fuel gas systems into TruST has now enabled automated ETS emission calculations using live composition, reducing the uncertainty, workload and risks involved.
This integration has also enabled complete remote surveillance capabilities of the fiscal and fuel gas systems on Leman and possible onshore intervention ensuring reliability and continued production.
A new single bay metering panel housed with one EXI SFC3000 flow computer and network equipment has been installed and powered up for the new Produced Water Re-Injection application. The second phase of I&C will consist of completing the PWRI flow computer application tests and the GE compressor control interface.
