Trans-Northern Pipelines upgrades ten-year-old SCADA system
Trans-Northern Pipelines upgrades ten-year-old SCADA system Trans-Northern Pipelines Inc. (TNPI) recently completed a major upgrade program to modernize its supervisory control and data acquisition (SCADA) system. When compared to the in-place, ten year-old SCADA system, the upgraded system provides enhanced connectivity, safety and efficiency. TNPI`s rationale for installing a new SCADA system was based on a number of economic and other factors. On the cost side, the high upgrade expenses associated with the dated hardware and software of the existing system created a strong justification for replacing the system. Apart from leak detection and batch tracking, a major focus of the upgrade was to consolidate points of measurement on the pipelines for ticketing, billing and EDI transfer to other organizations. TNPI decided at the specification stage that full functionality for each operator at product delivery points and centralized offices was needed. This fully automated an operator`s daily duties, increased accuracy of transportation and communicated valuable SCADA data to the people and processes that would need it. This paper describes the design, performance, and the design making process that went into this system.
