Ultrasonic Testing (UT) Services in Indonesia 2026 — ASNT Level III Led

Why Indonesia generates UT demand

Indonesia's market spreads across the archipelago — Pertamina's refinery upgrades, LNG at Bontang and Tangguh, the world's largest nickel processing build-out on Sulawesi, and coal and gas power across Java.

In refining, UT is the backbone of the corrosion programme — thickness monitoring at condition monitoring locations across crude, vacuum and coker circuits, shear-wave and phased array on repair welds, and high-temperature techniques where insulation cannot come off.

LNG service means cryogenic materials — UT on 9% nickel and stainless welds demands procedures qualified for the attenuation and geometry those materials bring, and thickness work on regas and boil-off circuits.

Mining equipment lives on UT — wear plate and chute thickness, dragline and shovel boom welds, and mill trunnion examination where a failure stops the whole train.

Power plant UT ranges from boiler tube thickness campaigns to turbine rotor bore and blade root examination, where phased array brings coverage a single-angle probe cannot.

What typically gets examined

In practice that means UT work across refinery units under RDMP upgrades, LNG trains, nickel smelters and processing plants, offshore platforms, and power station boilers — with scope set by the damage mechanisms each asset actually runs, not by a standard menu.

Certification and acceptance in Indonesia

Migas certification requirements apply to oil and gas work alongside owner specifications; B4T and Depnaker requirements touch statutory equipment, and the nickel smelter boom brings Chinese EPC quality systems into the same market as Western owner standards.

Examinations themselves are performed to ASME Section V Articles 4 and 5, ISO 17640 and ISO 16810, with thickness data feeding API 510, 570 and 653 remaining-life calculation. 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 Indonesia

Atlantis delivers ultrasonic 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 UT service overview, see how results are recorded and retrieved, or tell us about the Indonesia scope and we will respond with an honest view on mobilisation.

Work in Indonesia is delivered under the same procedures and Level III oversight described on our national ultrasonic testing page, which covers thickness surveys, weld examination, corrosion mapping and phased array performed to a qualified procedure.
