Radiographic Testing (RT) Services in Nigeria 2026 — ASNT Level III Led

Why Nigeria generates RT 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 fabrication yards radiograph structural and piping welds before load-out; in-service, radiography is used selectively where habitat access and source control can be arranged.

Girth weld radiography under API 1104 remains the default on new pipeline construction in most jurisdictions, with acceptance criteria that differ genuinely from plant codes.

Refinery turnarounds pull radiography for weld acceptance on piping tie-ins and vessel repairs, where a permanent image is required before insulation and fireproofing close the work.

Shipyard new-building and major steel renewal use radiography on butt welds in primary hull structure, to class society acceptance.

What typically gets examined

In practice that means RT 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 Article 2 and ISO 17636, with acceptance from the referencing construction code and API 1104 on pipeline girth welds. 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 radiographic 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 RT 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.
