SCADA Graphics and Controls

A subsidiary of one of the largest refiners in North America is responsible for safe and efficient operation of pipelines that transport crude oil to the refineries and distribute refined product. SKW was contracted to standardize key monitoring and control elements of the pipelines’ SCADA system through provision of the following:

API-compliant graphic displays

Line balancing and batch tracking smart objects

Operations/Reference Manuals

The SKW-designed standards replace the varying graphic symbols and control methods inherited from acquired pipelines so that operators can quickly adapt to different terminal and process locations, minimizing training time and enhancing safety.

Deployment of a standard line balance control “smart object,” compliant with all PHMSA requirements contributes to safety and environmental security. Precise batch tracking informs marketing of the availability of each products on a real-time basis, facilitating “spot” sales and allowing for fine-tuning of refining operations to meet fluctuating demand.

The API’s Recommended Practice for SCADA Pipeline Displays identifies best practices for development of human machine interfaces (HMI) to provide optimal transfer of information to the user. The API-compliant display standards developed by SKW encompass graphics screen layout, equipment and processes, screen navigation, and alarm and event handling.

An example of the new standard is the banner that displays at the top of every screen showing Batch Status, Alarms, and Leak Detection data. These critical variables are placed where they most naturally draw the operator’s attention.
