Services · 10 disciplines
Engineering, maintenance & repair — one team.
Turnaround & shutdown, call-off maintenance, asset integrity, corrosion protection, surface preparation & coating, mechanical maintenance and emergency repairs — for onshore, offshore, LNG and marine assets.
Maintenance, Turnaround & Shutdown
Reliability · Safety · Uptime
Maintenance services for the oil & gas industry — ensuring asset reliability, safety and operational excellence. A shutdown takes a unit offline for inspection, maintenance and upgrades, and every day of it costs production. PEC plans call-off and turnaround scopes to bring plants back online safely and on schedule.
