ABOUT THESE PROJECTS

ISC worked in a major petroleum refinery for 15 years providing ongoing SIS and SIS related DCS development. In these implementations, ISC provided the entire EPC delivery of all site SIS upgrades and new system installations. As a part of that long standing assignment, our engineers, designers and construction leads worked closely with plant engineering, operations and maintenance personnel to install on-budget, on-schedule SIS/DCS projects. These systems meet industry and company compliance standards, but even moreover provide intelligent, operable, maintainable process protection solutions.

This particular customer operates their facility utilizing Honeywell TDC3000 (upgraded over this project span to Experion) and Triconex Tricon and Trident SIS platforms. The critical turbomachinery controls in this facility are also controlled via Triconex Tricon platforms.  ISC Engineering and Construction also engineered (with Honeywell) the DCS migration to Experion, and implemented the cutovers. As well, ISC engineered and constructed the upgrade of the Tank Farm automation and controls (DCS/SCADA).

ENGINEERING & CONSTRUCTION SCOPE:

  • Participated in the front end risk assessment of each target instrumented protective function and overall control system scheme
  • Worked with plant engineering staff to generate the instrumentation, electrical and control system engineering and construction work scopes, schedules and cost estimates (+/- 30 and +/-10) for plant funding processes
  • Completed detailed instrumentation, electrical and controls engineering design engineering packages to facilitate construction:
    • Instrument Specifications
    • Location Plan Drawings
    • Junction Box Wiring Drawings
    • Loop Drawings
    • SIS PLC Cabinet Integration and Wiring Drawings
    • Wiring Demolition Drawings
  • Completed all systems engineering functions consisting of the following:
    • SIS PLC Logic Narratives
    • C & E Matrices
    • Configuration and Programming of SIS PLC
    • DCS Configuration and Graphics Development for PLC SIS Interface
    • Factory Acceptance Test Procedures
    • Customer Witnessed Integrated FAT of DCS and SIS PLC Equipment
  • Generated SIS on-line and off-line testing procedures
  • Modified existing operating procedures to reflect SIS changes
  • Created training material and facilitated operating training of SIS system additions/changes
  • I/E construction
    • Procurement of New SIS Engineered Tag Items
    • Installation of New Infrastructure and New SIS Instrumentation
    • Calibration and Loop Check of New SIS Instrumentation
