Asset Integrity Digital Twin for Nigeria
Atlantis Digital Twin puts measured inspection data, API 581 risk-based inspection scoring and API 579-1/ASME FFS-1 fitness-for-service on a single live 3D model of the asset, for operators and integrity contractors working in Nigeria.
The asset base this is built for
The Dangote refinery and petrochemical complex, NNPC and its joint ventures, Shell, TotalEnergies, Chevron and ExxonMobil offshore assets, Port Harcourt and Warri refining, and the FPSO fleet operating in the Gulf of Guinea.
The regulatory and code environment
NUPRC and NMDPRA regulate upstream and midstream/downstream operations respectively, with NCDMB local-content requirements shaping how contractors staff and register. Inspection follows ASME Section V, VIII and IX, API 510/570/653 and API 580/581, with ISO 9712 or ASNT personnel certification and, offshore, class-society requirements.
Why it matters here specifically
Offshore and FPSO work here carries very high mobilisation cost and constrained inspection access, so inspection planning quality has an outsized effect on total cost — and evidence provenance matters because operator audits are frequent and documentary.
What the twin does
- Binds every thickness reading and indication to a CML or TML with persistent identity, so a reading taken years apart is genuinely comparable.
- Assigns damage mechanisms per API RP 571 against actual process service — sulfidation, naphthenic acid corrosion, HTHA per API 941, wet H2S cracking, chloride SCC, CUI, MIC, erosion-corrosion — so inspection targets the mechanism that is credible for that circuit.
- Computes RBI under API 580/581 from measured corrosion rates rather than defaults, which changes which equipment is genuinely flagged.
- Runs API 579 Level 1 and Level 2 assessments — Part 4 general metal loss, Part 5 local metal loss, Part 9 crack-like flaws — against the stored thickness grid, rendering pass/fail zones spatially.
- Retains full provenance on every record: procedure revision, inspector certification state and instrument calibration state at the time of test.
- Integrates with SAP PM, Oracle eAM, IBM Maximo, ServiceNow, AVEVA PI and OSIsoft historians, with documented REST API and full bulk export.
Regional asset detail
- Lagos — Lagos serves as the commercial hub for Nigeria's petroleum industry, with the Dangote Refinery — Africa's largest at 650,000 bpd capacity — recently commissioned alongside existing NNPC-operated refineries and the growing deepwater offshore sector. The scale of new refinery assets and the need to establish world-class inspection data management from commissioning create an ideal environment for digital twin implementation.
- Port Harcourt — Port Harcourt serves African energy, refining, mining, or maritime operator workflows where Atlantis NDT Digital Twin platform integrates inspection + RBI + FFS data with Sonatrach, NNPC, Sasol, Sapref, Engen, Sonangol, Tullow, Anglo American, Glencore operator stacks. Affordable, accessible, fully customizable..

Frequently asked questions
What does an asset integrity digital twin change for operators in Nigeria?
It moves the integrity case from a spreadsheet snapshot to a live model. Every UT, PAUT, TOFD, RT, MT, PT and ET reading binds to a corrosion monitoring location with a persistent identity, so corrosion rates come from a real time series rather than an assumed default. RBI under API 580/581 then ranks on measured condition, and API 579 fitness-for-service runs against the stored thickness grid. Offshore and FPSO work here carries very high mobilisation cost and constrained inspection access, so inspection planning quality has an outsized effect on total cost — and evidence provenance matters because operator audits are frequent and documentary.
Which codes and regulators does it have to satisfy in Nigeria?
NUPRC and NMDPRA regulate upstream and midstream/downstream operations respectively, with NCDMB local-content requirements shaping how contractors staff and register. Inspection follows ASME Section V, VIII and IX, API 510/570/653 and API 580/581, with ISO 9712 or ASNT personnel certification and, offshore, class-society requirements. Every record carries provenance — which procedure revision was in force, which inspector performed the work and what their certification state was at that moment, and whether the instrument was in calibration — which is the bundle a regulator, insurer or client audit actually asks for.
Do we need to laser-scan the plant first?
No. Geometry can come from LiDAR or photogrammetry capture, drone survey, or from existing BIM, CAD, isometrics and P&IDs. Many first deployments start from isometrics and add scan-derived geometry later, because reconciling the CML register — not capturing geometry — is the task that actually gates the timeline.
How long until the first unit is live?
Ten to fourteen weeks is typical: two to three weeks of geometry capture or import, three to four weeks reconciling the CML register and importing historical thickness data, two to three weeks assigning damage mechanisms per API RP 571, then RBI and FFS configuration and integrity-team training. Subsequent units are considerably faster once the data model and conventions are set.
