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

Why Nigeria generates UT demand

Nigeria's inspection demand centres on the Niger Delta — offshore platforms and FPSOs, an ageing pipeline network under constant integrity pressure, and the Dangote refinery, which added a world-scale process complex to Lagos overnight.

Offshore, UT carries both topside integrity — thickness on separators, risers and process piping — and structural work, with lamination checks and weld examination on primary steel.

Pipeline integrity leans on UT to verify in-line inspection calls — direct assessment digs confirm metal-loss depth at the anomalies MFL reported, and AUT examines new girth welds where radiography is displaced.

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.

Marine work is thickness gauging at scale — hull plating diminution against class allowables, tank internals, and shaft and rudder stock examination during docking.

What typically gets examined

In practice that means UT work across FPSO topsides and hulls, delta flowlines and export pipelines, Dangote and NNPC refinery units, and terminal and jetty infrastructure — with scope set by the damage mechanisms each asset actually runs, not by a standard menu.

Certification and acceptance in Nigeria

NUPRC and NMDPRA oversight frames oil and gas work, operators run their own stringent vendor approval, local-content rules under NOGICD shape crew composition, and security planning is part of every field mobilisation in a way it is not elsewhere.

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 Nigeria

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 Nigeria scope and we will respond with an honest view on mobilisation.
