2017-2018
Minimized station down time through constructability sequencing.
Collaborative and integrated project team.
Simultaneously executed PLC hardware and PLC programs upgrades.
Challenges
- Hatch was retained by Pembina Pipeline Corporation (Pembina) to replace a number of discontinued Liquid-Cooled Variable Frequency Drives (VFD) with Air-Cooled VFDs at multiple pump stations on a Northeastern Alberta pipeline system.
- Hatch first conducted pre-FEED evaluation of viable replacement or upgrade options for each of the six facilities.
- Conducted a risk analysis of the outage time required to change the equipment.
Solutions
- Recommendations were made based on a detailed technical assessment and considerations for cost, reliability, operability, and constructability.
- Collaboration allowed the new equipment to be installed with minimum shutdown time and minimum disruption to the pipeline operation.
- Designed new electrical buildings at three of the sites.
Highlights
- The level of collaboration was very high between Hatch, Pembina engineering and the operations teams, site construction contractors, and the commissioning group.
- A parallel project to upgrade the station PLC hardware and PLC programs was successfully executed simultaneously with the VFD Replacement project, which added another dimension of complexity to the overall execution.
