NDT Training in New Orleans — ASNT SNT-TC-1A Level I, II and III
Atlantis NDT delivers employer-based NDT training in New Orleans, USA: ASNT Level III-led Level I and Level II courses, examinations and certification records issued under your company's SNT-TC-1A or CP-189 written practice. New Orleans NDT training for Gulf Coast refineries, petrochemical plants, and offshore operations. Training runs on-site at your facility with instructors mobilised from Atlantis NDT's Houston, Texas base for the engagement, or as online theory with an in-person practical — there is no requirement to send technicians to a school.
Employer-based certification under SNT-TC-1A
In the United States, NDT personnel are qualified and certified by their employer under a written practice that follows ASNT Recommended Practice SNT-TC-1A, or the ANSI/ASNT CP-189 standard. Atlantis NDT works inside that structure: an ASNT NDT Level III reviews or authors your written practice, delivers the classroom hours SNT-TC-1A recommends for each method and level, administers the general, specific and practical examinations, and signs the certification records your customers and auditors ask to see.

Methods and levels delivered in New Orleans
Level I and Level II courses in ultrasonic testing (UT, including thickness and shear-wave weld examination), phased array UT (PAUT), radiographic testing and film interpretation (RT), magnetic particle testing (MT), liquid penetrant testing (PT), visual testing (VT) and eddy current testing (ET), each built to the SNT-TC-1A training-hour tables and examined against your procedures on your equipment. Level I and Level II cohorts typically run three to ten days per method; Level III candidates are prepared for the ASNT Basic and Method examinations.
What a New Orleans employer receives
A written practice reviewed or authored to SNT-TC-1A 2024 or CP-189, course records showing the hours delivered per technician, examination papers and graded practicals with the specimens used, a certification record per person per method, and a recertification calendar. The file is prepared to survive a customer audit — the question an auditor asks in New Orleans is not where the technician trained but whether the employer's certification record is complete. Ongoing Level III oversight is available through outsourced ASNT Level III consulting.
Delivery in New Orleans
On-site cohorts of 4 to 25 technicians at your plant, yard or shop, with Atlantis NDT bringing calibration blocks, reference specimens and examination materials; blended delivery with the theory online and the practical on your equipment; or fully online theory for Level I and Level II general examinations where your written practice permits it. Instructors and examiners are mobilised from Houston for the duration of the engagement. See employer-sponsored NDT training and NDT training across the US.

In more detail
A Level II certificate rests on three separate examinations: a general exam on the method's underlying physics and equipment, a specific exam on the employer's own procedures and product forms, and a practical exam demonstrating the technique on real specimens. SNT-TC-1A recommends passing grades of 70% general, 70% specific, and an 80% composite average across all three.
New Orleans sits at the foot of the River Parishes petrochemical corridor running upriver toward Baton Rouge, one of the densest concentrations of refining and chemical processing capacity in North America, and close to Port Fourchon, the onshore logistics base that services most Gulf of Mexico deepwater oil and gas production, along with the Louisiana Offshore Oil Port, the only US terminal able to receive fully loaded supertankers. The Port of New Orleans itself moves heavy steel, project cargo and fabricated modules that get examined before and after shipment. Layered on top of that industrial density is a coastal, hurricane-exposed, high-humidity environment that accelerates corrosion under insulation and atmospheric corrosion on external piping and tankage — which is why thickness survey frequency in this region often runs tighter than the code minimum rather than to it. A technician certifying here is certifying into that combination of asset density and corrosion severity, not into a generic Gulf Coast market.
| Exam component | What it actually tests | Set by | SNT-TC-1A recommended passing grade |
|---|---|---|---|
| General | The method's underlying physics, equipment, controls and standard terminology — content that does not change between employers | SNT-TC-1A body of knowledge for the method | 70% |
| Specific | The employer's own written procedures, equipment models, product forms and acceptance criteria | Employer's Written Practice | 70% |
| Practical | Hands-on calibration, examination, interpretation and reporting on real or representative specimens | Employer's Written Practice, administered by a Level III | 80% |
| Composite (all three) | Overall competency combining demonstrated knowledge and skill | SNT-TC-1A recommended minimum | 80% average |
What a compliant Written Practice actually documents
The Written Practice referenced throughout this page is not a policy statement — it is a detailed technical document, and understanding what it actually contains explains why an auditor asks for it before the certificate. A compliant Written Practice under SNT-TC-1A sets out, per method and per level: the education and experience prerequisites a candidate must hold before sitting for certification; the minimum classroom training hours; the structure and content of the general, specific and practical examinations, including minimum passing grades; the frequency of the near-vision acuity and color-contrast examination; the interval at which certification must be renewed and whether renewal requires reexamination or documented evidence of continued satisfactory performance; and the conditions under which a certification can be suspended, revoked or reinstated. It is signed by the employer's Level III, who carries responsibility for everything in it.
SNT-TC-1A is a recommended practice, not a mandatory standard, so an employer is free to adopt its recommended tables as written or to modify them — shortening a recertification interval, adding a method-specific practical exercise, raising a passing grade — provided the modification is documented and defensible. That flexibility is the entire point of the SNT-TC-1A model, and it is also why two Level II certificates issued by two different Gulf Coast employers, even in the same method, are not necessarily built to the same requirement. Companies without an in-house Level III typically engage an outsourced Level III to write and administer it, which does not change what the document has to contain. A client auditor reading the Written Practice is checking exactly that: not whether a certificate exists, but whether the document behind it holds up.
The three-part examination and what each part is actually checking
Every method-level certification under SNT-TC-1A rests on three separate examinations, and conflating them is a common misunderstanding among candidates preparing for a first Level II. The general examination tests the fundamentals of the method itself — the underlying physics, the equipment and its controls, standard terminology and reference procedures — content that does not change from one employer to the next and that maps onto the broader body of NDT standards referenced across every code stack an inspector works under. The specific examination tests the candidate against the employer's own written procedures: the equipment models actually in use, the product forms and material thicknesses actually examined, and the acceptance criteria the employer's contracts actually reference. The practical examination is a hands-on demonstration — calibrating the equipment, examining a real or representative specimen, interpreting the indication, and producing a report that would stand in a client's file. SNT-TC-1A recommends passing grades of 70% for the general and specific examinations and 80% for the practical, with an 80% composite average across all three; an employer's Written Practice can set a higher bar but rarely a lower one.
Recertification follows the same three-part logic on a longer interval. SNT-TC-1A leaves the exact renewal period to the employer's Written Practice but recommends it not exceed five years, and requires either reexamination or documented evidence of continued satisfactory performance in the method at renewal, on top of an annual near-vision acuity and color-contrast check that runs independently of the certification cycle itself. A technician whose eyesight fails that annual check is not qualified to interpret indications regardless of how recent the certificate is.
Where Louisiana's NDE demand actually concentrates
The industrial geography around New Orleans is not evenly spread, and a training programme built for this market benefits from following where the work actually sits rather than treating the whole Gulf Coast as one undifferentiated zone. Running north from New Orleans along the Mississippi River, the River Parishes — St. Charles, St. John the Baptist, St. James and neighbouring parishes — carry one of the densest concentrations of refining and petrochemical processing capacity in North America, all of it running scheduled turnarounds that pull heavily on ultrasonic thickness surveys, shear-wave weld examination and radiography. South and west of the city, Port Fourchon functions as the onshore logistics base for the large majority of Gulf of Mexico deepwater oil and gas production — subsea trees, risers, platform modules and supply vessels moving through it all carry inspection requirements before deployment and after recovery. The Louisiana Offshore Oil Port, the only US deepwater terminal able to receive a fully loaded supertanker without lightering, sits offshore from the same corridor. Closer to the city, the Port of New Orleans and the marine fabrication and repair yards along the lower Mississippi examine hull structure, cranes and heavy steel to ABS and USCG survey requirements, where magnetic particle carries most of the volume on fatigue-critical welds.
Layered across all of it is the coastal climate: prolonged humidity, salt-laden air and hurricane exposure that together accelerate corrosion under insulation on piping and vessels, and atmospheric corrosion on unlagged steel. That is a genuine, measurable driver of inspection frequency in this specific region, not a generic Gulf Coast talking point, and it is one reason experienced Louisiana inspectors are valued for judgment about where to look, not only for a certificate that says they are allowed to. Atlantis runs this same on-site, follow-the-work model across other Gulf Coast and national training locations, because the logic — go to the crew rather than make the crew travel — does not change with geography.
Louisiana's LNG build-out downriver in Plaquemines Parish and along the western part of the state adds a further, distinct source of demand: new-construction inspection on liquefaction trains and cryogenic piping calls for radiography and phased array on welds that will operate at temperatures far below anything a typical refinery unit sees, which is a different qualification emphasis than a turnaround crew doing routine thickness surveys. A New Orleans-based technician who wants to work that scope needs method qualification that specifically covers the applicable code — usually ASME Section VIII and B31.3 with project-specific procedure qualification — rather than assuming a general Level II covers it automatically.
Corporate cohorts versus individual enrollment — what actually changes
The practical differences between an employer-sponsored cohort and an individual signing up alone go beyond who pays. A corporate cohort is scheduled around the client's own production calendar — often built to land before a turnaround window rather than on a fixed public calendar — and it trains against the employer's own Written Practice from day one, using the employer's own equipment models and, where possible, specimens that resemble what the crew will actually examine in production. Every technician in the cohort finishes with a personnel file built the same way: same procedures, same Level III administering the exams, same documentation format. That consistency is what a client audit is actually looking for when it reviews a contractor's technician roster — not that certificates exist, but that they were issued under one coherent, defensible process rather than assembled from whatever each technician happened to bring from a previous employer.
An individual enrolling alone does not get that head start. Training can be completed through a scheduled cohort or blended delivery, but the certificate itself still has to be issued by an employer against that employer's Written Practice — SNT-TC-1A does not permit a training provider to certify someone into a vacuum. That means the practical bottleneck for an individual is rarely the training itself; it is finding the employer relationship that will certify against documented on-the-job hours once training is complete. Candidates who line up an employer first and training second generally reach a working Level II certificate faster than candidates who train first and look for work afterward, simply because the experience clock cannot start until the employment does. For a crew with a turnaround date already on the calendar, the useful next step is a direct conversation about scheduling a cohort rather than a generic quote request.
Procurement looks different too. A corporate cohort is typically arranged well ahead of a turnaround window and locked into a training and outage schedule set months in advance, while an individual candidate typically enrolls into whatever cohort or blended slot is next available. Neither path is a shortcut around the underlying experience requirement, but a company sending a full crew through the same cohort captures a second benefit an individual cannot: the Level III running the exams already knows the plant's own procedures and equipment, so specific and practical exam content is built around exactly what the crew will be examining on Monday morning rather than a generic industry scenario.
What passing grade does SNT-TC-1A recommend for a Level II examination?
SNT-TC-1A recommends a minimum of 70% on the general examination, 70% on the specific examination, and 80% on the practical examination, with an 80% composite average required across all three. An employer's Written Practice can raise those thresholds — some Gulf Coast operators require a higher composite for methods tied to fitness-for-service decisions — but SNT-TC-1A discourages setting them lower, since the recommended grades already represent a floor rather than a target.
How often does a Level II certificate need to be renewed?
SNT-TC-1A leaves the exact interval to the employer's Written Practice rather than fixing one, but recommends it not exceed five years and requires either reexamination or documented evidence of continued satisfactory performance in the method at renewal. Layered on top of that cycle is an annual near-vision acuity and colour-contrast check that runs independently — a technician can hold a current certificate and still be pulled from interpretation duty on a failed vision test.
Why does a coastal climate like New Orleans change inspection frequency?
Prolonged humidity, salt-laden air and repeated hurricane exposure accelerate corrosion under insulation on piping and vessels, and atmospheric corrosion on unlagged steel, faster than a code-minimum inspection interval assumes. Operators in this region commonly shorten ultrasonic thickness survey frequency below the API 510 or API 570 code minimum in response to actual measured corrosion rates, not because the code requires it — a judgment that rests on inspection history, not on the certificate alone.
Does a corporate cohort still produce individually issued certificates?
Yes. Each technician in a cohort is examined and certified individually against the same employer Written Practice — there is no shared or group certificate under SNT-TC-1A. What a cohort standardizes is the process behind those individual certificates: the same Level III administering every exam, the same procedures, equipment and specimens, and the same documentation format, so the resulting personnel records are consistent across the whole crew rather than reflecting whatever each technician's prior employer happened to document.
What role does Port Fourchon play in Louisiana's NDE demand?
Port Fourchon is the onshore logistics base supporting the large majority of Gulf of Mexico deepwater oil and gas production, so the subsea trees, risers, platform modules and supply vessels staged through it all carry method-level inspection requirements before deployment and again after recovery for repair or requalification. That steady traffic is one reason ultrasonic and magnetic particle demand in this region tracks offshore activity as closely as it tracks refinery turnaround schedules.
