Project Scope

Avanceon was mandated with the procurement, supply, delivery, installation, testing and commissioning of the entire Truck Loading Automation System [TLAS] of the OGDCL KPD site regarding its custody transfer and operations management.


The main challenge and objective of this project was to deliver an Inventory Management and Product Delivery Solution based on field instruments, control system hardware and Truck Loading software which enabled an accurate custody transfer from plant to loading trucks, managing transactions, keeping a historical record of the transaction and generating on demand reports. The scope of work was to deliver a fully functional PlantPax DCS for controlling and monitoring field instruments and management software for transaction management


The deliverables of the project included the detailed design, development, supply, delivery, and commissioning of the TLAS System for the OGDCL KPD site for custody transfer and operations management. It was agreed that transfer would apply to LPG and condensate, which would be using three bays, each with a dedicated batch controller and loading arm and real time monitoring of gantry operations. The system was based on PlantPax DCS included HMIs, alarm and event servers and historian module.

TLAS System Topology
The system was built to allow information flow from the field layer on to the DCS ad the TLAS Management software.

The system overview

  • TLAS Control Room controlled and monitored all bay operation via PlantPAx HMI with all field devices connected
  • TLAS-CS Client station and the HMI are showing statuses of the field devices installed at loading bays, including monitoring bay operation, runtime status of pumps, alarms, and trends

  • TLAS-MS Client operator station was provided at the Control Room and carried out terminal operations including: creating/maintaining customer orders, drivers and carrier companies data, manual entry of truck loading order and shipments, updating RFID, and managing queue management and assigning loading bay to the shipment

  • TLAS-MS Server was responsible for maintaining TLAS DBs and FT Historian

Batch Controller Unit [BCU]
The main function of the batch controller was to assist the loading of the liquid products at the storage area to another containment vessel. The batch was also built to smooth the movement and ensure measurement accuracy of the product.

TLAS-MS Application & Software Application

  • Terminal rules for truck
  • TLAS-MS bay assignment rules for truck loading

  • User management
  • Weighbridge
  • Report management through SQL server reporting services

  • TLAS-MS manual entry
  • TLAS-MS process rules


The TLAS for the Kunnar Pasakhi Deep project was successfully delivered and commissioned as per applicable standards. The project designed, developed, supplied and commissioned the entire system in the presence of all stakeholders involved.
