EPC Support Services
Manpower · Materials · Site support
PEC supports EPC contractors and project owners with the people, materials and site services a project needs, from skilled and semi-skilled manpower on site to timely material supply, through construction, commissioning and handover.
PEC offers EPC services through its partner companies.
Manpower on siteMaterial supply
Site support
Skilled and semi-skilled manpower supply for site works
Mechanical, piping and coating site works
Construction and industrial equipment rental
Shutdown and turnaround support
Pre-commissioning and commissioning support
Inspection, testing and QA/QC support
Material supply
Reliable, timely delivery of steel pipes and fittings, pumps, spare parts, consumables and PPE through a strong vendor network and strict quality control.
Inspection, testing and reliability engineering for enhanced safety and regulatory compliance. Quality checks and NDT testing confirm the steel before anything is sealed in, and every PEC repair is inspected before the asset is handed back to operations.

From PEC's project record
Supply and technical support for NDT activities along the MIC GASAL GAN pipeline — GASAL Q.S.C., 2018
Rubber lining inspection on mixed bed vessels, with in-situ rubber lining repair — Q-Chem, 2023
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.
The first link in PEC's complete downstream maintenance package for oil & gas, LNG facilities and marine assets — turnkey packages rather than just raw material supply.

EPRS — Emergency Pipeline Repair Systems
Onshore · Offshore · Subsea · With 3X Engineering
When a line leaks, waiting for a shutdown is not an option. EPRS seals the leak online — in minutes, without interrupting operations — and then restores integrity with composite repair designed to ISO 24817 and ASME PCC-2. PEC offers 3X Engineering's EPRS kits — STOPKiT®, STOPKiT® VESSEL and FIXOKiT® — for Qatar's onshore, offshore and subsea installations.

02Reinforce with composite
Composite repair, designed to ISO 24817 and ASME PCC-2, restores long-term integrity.
03Inspect & hand over
The repair is inspected and the asset is handed back to operations.
