Oil & Gas / Petrochemical
Process plants, pipe racks and pressure systems — construction under a permit-to-work culture.
An oil and gas facility is structural steel, pressure systems and an unforgiving permit-to-work culture. The civil works are heavy — foundations for rotating kit, blast-rated buildings, piperack steelwork by the thousand tonnes — but the job is really about installation: piping, electrical and instrumentation, then a pre-commissioning and start-up sequence that brings the plant to life one system at a time.
The four guides in this sector cover the facility works. The site access, survey and ground-investigation guides are shared with Power Generation and link through to their canonical pages there.
What does Oil & Gas / Petrochemical cover?
Process guides in Oil & Gas / Petrochemical
- Heavy Civils & Foundations — Equipment foundations, machine blocks, tank bases and piperack civils — the concrete that a process plant stands on, and the anchor bolts everything else lines up from.
- Structural Steel & Equipment Setting — Piperack steel, technological structures and the heavy lifts that land vessels, columns and compressors onto the civils — planned to BS 7121 and surveyed to the millimetre.
- Piping & E&I Installation — Pressure piping fabricated as spools and welded to qualified procedures, plus the cable, tray and instrument installation that makes the plant controllable — the longest bulk-installation phase on the job.
- Pre-commissioning & Start-up — Proving the plant without hydrocarbons — testing, flushing, drying and inerting — then the readiness reviews and controlled first introduction of feed that turn a construction site into an operating facility.
