Third-party inspection and document review for Western clients ordering ASME-coded pressure vessels, heat exchangers, and offshore structures from Korean fabricators.
South Korea is home to four of the world’s most technically capable heavy fabrication companies: HD Hyundai Heavy Industries, Samsung Heavy Industries, Hanwha Ocean (formerly DSME), and Doosan Enerbility. These shops fabricate some of the most demanding pressure equipment in the world — hydrocracking reactors, high-pressure hydrogen vessels, large-diameter pressure vessels for LNG and offshore applications, and heavy forgings.
The reason Western oil and gas clients require their own third-party inspection at these facilities is not a quality concern about Korean capability — it is a contractual requirement. The purchase order between the Western client and the Korean fabricator specifies the client’s inspection requirements, and independent TPI is the mechanism that verifies those specific requirements were met, separate from the fabricator’s own QC and the ASME AIA.
Norman QC provides the North American QA layer for Korean fabrication: remote document review of WPS/PQR and ITP packages before fabrication begins, and targeted on-site visits at defined hold points, with signed PDF reports delivered to the Western client.
| Code | Application |
|---|---|
| ASME Section VIII Div.1 / Div.2 | Pressure vessel fabrication |
| ASME B31.3 | Process piping |
| ASME Section IX | Welding qualification |
| TEMA | Heat exchanger mechanical design |
| Western Client Project Specifications | Client-specific purchase order requirements |
Korea’s major ASME-authorized fabricators are concentrated in the southern industrial cities. HD Hyundai Heavy Industries operates the world’s largest shipbuilding complex in Ulsan, where its process plant division fabricates ASME-coded pressure equipment. Samsung Heavy Industries is based in Geoje. Hanwha Ocean (formerly Daewoo Shipbuilding & Marine Engineering, DSME) operates in Geoje. Doosan Enerbility, specializing in nuclear-grade and high-alloy pressure vessels, is based in Changwon. These four facilities between them account for the majority of Western oil and gas orders from Korea.

Why do Western clients require their own inspector at Korean fabricators?
Korean fabricators are technically world-class — the equipment they build is genuinely excellent. The reason Western clients mandate their own TPI is contractual: the purchase order is between the Western client and the Korean fabricator, and the client's QA requirements specify independent oversight. The TPI verifies that the fabrication followed the client's specific WPS, ITP, and material requirements — not just the general ASME code requirements. It also provides an independent QC record that the client controls, separate from the fabricator's own documentation.
Does NormanQC review Korean fabrication documentation in English?
Yes. Major Korean fabricators — HD Hyundai Heavy Industries, Samsung Heavy Industries, Hanwha Ocean, Doosan Enerbility — prepare all documentation for international orders in English. WPS/PQR packages, ITPs, material test reports, NDE procedures, and inspection reports for Western client orders are in English. Remote document review from Edmonton is fully practical.
What hold points are typically required for Korean-built pressure vessels?
For a standard ASME VIII pressure vessel fabricated in Korea, typical hold points include: ITP and WPS/PQR approval before fabrication; material traceability verification before cutting and welding; fit-up and dimensional check at mid-fabrication; NDE completion and record review; pressure test witnessing (if designated as a hold point); and pre-shipment dimensional and nameplate inspection with shipping release. Complex equipment — thick-wall reactors, alloy vessels, PWHT-required items — may have additional hold points.
Which Korean fabricators does NormanQC cover?
Norman QC coordinates source inspection at all major Korean fabrication facilities, including HD Hyundai Heavy Industries (Ulsan), Samsung Heavy Industries (Geoje), Hanwha Ocean (Geoje), and Doosan Enerbility (Changwon). These are the four principal Korean fabricators for Western oil and gas pressure equipment and offshore structures.
What is the typical timeline for a Korean source inspection engagement?
Engage at purchase order confirmation. Remote document review (WPS/PQR, ITP) takes 3 to 7 business days depending on document volume. On-site visits are scheduled 2 to 3 weeks in advance of each hold point. Pre-shipment inspection is the final visit. For a typical vessel fabrication run of 3 to 6 months, the engagement begins immediately after PO confirmation and concludes with the shipping release.
