Delivering prefabricated substations

The client needed an independent certification partner providing multi-discipline design review, certification, inspection, and hazardous area compliance for prefabricated substations and buildings.

Prefabricated substations

McPEC required Australian-compliant certification for five prefabricated substation buildings manufactured offshore at its Batam yard and delivered to the Burrup project in Australia.

The project involved complex, multi-discipline certification requirements, extensive documentation under shifting priorities, and strict Australian regulatory compliance. Any failure would have created rework risk, schedule delays, and regulatory exposure.

Waterline delivered a packaged engineering solution, acting as McPEC’s trusted certification partner over a two-year period, delivering:

  • Design review and certification of prefabricated substation buildings
  • Switchroom certification
  • Compliance with AS/NZS 3000 and the National Construction Code
  • Structural, architectural, fire rating, and electrical certification
  • Hazardous area inspections in accordance with AS/NZS 60079, securing IECEx/ANZEx certification
  • Fire detection system design reviews for Australian compliance

Five substations were successfully certified for operation in Australia, meeting all regulatory and compliance requirements.

Certification was achieved without impacting fabrication schedules or delivery timelines, protecting overall project momentum.

Hazardous area and fire protection systems were validated to both Australian and relevant international standards, ensuring safety and operational integrity.

Despite evolving project demands, certification outcomes remained consistent, reliable and aligned with compliance expectations throughout.
