Mission Valley Automation Skid Project

Project Summary


In this project I had the opportunity to work with brilliant engineers and multiple amazing teams on the 66 acres, 30 refined petroleum tanks with total capacity of 68382 barrels and design, do the procurement on multiple control valves, programmable logic controllers. I also designed various control loops on PIDs to ensure the sensors and final control elements are fully capable to address the requirements of the terminal.


Motor Control Center

One of the most challenging tasks of this project was the design and provision of indication and control signals from the MCC to the control center where PLC and SCADA systems can act on the signals, and take the right control strategy for the pumps and Variable Frequency Drives (VFDs).

Local Start / Stop Motor Stand with PLC Logic

I designed the control strategy for the emergency shut down, local start/stop, feedback loop and notification of the motors to the Remote Terminal Units (RTUs).

Selecting Control Valves and Final Control Elements

I reviewed the engineering design requirements and contacted various vendors to inquire about the requirements. After I ensured that the product would meet our engineering standards, I prepared the engineering data sheets as well as requisition for purchase and then completed the procurement process for in time delivery.

Design & Implementation of Feedback Control Loops

I designed the control strategy to make pumps function safely and transfer the medium to the delivery skid. I also ensured the control strategy are implemented successfully in PLC and SCADA for state data monitoring.

Fuel Terminal Control Design

In this section, I tapped into the analyzers, transmitters and designed the control and monitoring strategy for the fuel transfer.



This project was an amazing opportunity to work in various fields such as control, instrumentation, electrical power, data transfer, programmable logic controllers, setting up RTUs. Fortunately, the coordination with different engineering teams was perfect and we could resolve any problem in shortest amount of time.
