Visual Testing (VT) Services in Vietnam 2026 — ASNT Level III Led

Why Vietnam generates VT demand

Vietnam's Dung Quat and Nghi Son refineries, the offshore fields off Vung Tau, fast-growing fabrication yards taking regional work, and a coal-to-gas power transition give it one of Southeast Asia's fastest-expanding inspection markets.

Every refinery inspection starts visual: external corrosion under insulation evidence, support and foundation condition, and internal vessel entry examinations that decide what the rest of the scope becomes.

General visual inspection programmes on platforms feed the anomaly register that drives everything else — coating breakdown, anode depletion, dropped-object damage and seafastening condition.

CWI-style visual acceptance is the first gate on every production weld: profile, undercut and reinforcement checked before any volumetric method is spent.

Boiler internal inspections, casing and duct condition, and remote visual work in headers and drums set the volumetric scope for every outage.

What typically gets examined

In practice that means VT work across refinery process units, offshore platforms and FSOs, fabricated jackets and modules for export, and new-build power plant — with scope set by the damage mechanisms each asset actually runs, not by a standard menu.

Certification and acceptance in Vietnam

PetroVietnam group specifications lead oil and gas work with international codes applied directly; ASNT certification is the accepted currency, and yards building for export work routinely host client and class surveillance on top of local requirements.

Examinations themselves are performed to ASME Section V Article 9, AWS D1.1 visual acceptance for structural welds, and API 510, 570 and 653 in-service visual requirements. The evidence chain — technician certification current on the day, instrument and reference block calibration, and the procedure revision in force — travels with every report, because that bundle is what an audit actually checks.

Working with Atlantis in Vietnam

Atlantis delivers visual testing through inspection teams mobilised to site, working under Atlantis procedures with ASNT Level III oversight — we are straightforward that this is a mobilised model rather than a walk-in local office, because for planned inspection work that is usually the better arrangement anyway: the crew, procedures and equipment arrive matched to your scope. Read the VT service overview, see how results are recorded and retrieved, or tell us about the Vietnam scope and we will respond with an honest view on mobilisation.

Work in Vietnam is delivered under the same procedures and Level III oversight described on our national visual testing page, which covers direct and remote visual examination against named acceptance criteria, with the evidence chain written to survive an audit.
