Maritime & Shipbuilding NDT Training in San Diego, California
San Diego combines NASSCO's new construction with one of the largest ship-repair concentrations on the West Coast, plus the naval base's own demand. Repair-side examination — thickness surveys, weld repair acceptance, class survey support — dominates the hiring, and the aluminium content of modern vessels keeps PT unusually prominent alongside the standard MT/UT load.
Maritime & Shipbuilding NDT in brief
Maritime NDT is its own world. The product is enormous, the material is thick section steel and increasingly aluminium, the welding is measured in miles, and the acceptance regimes — classification societies on the commercial side, NAVSEA technical publications on the naval side — are unlike anything in general plant work. Training for it has to reflect that, which is why a shipyard NDT technician's qualification path looks different from a refinery technician's from the first course onward.
What maritime & shipbuilding training covers
Volumetric weld examination dominates: UT on hull butts and seams, with phased array increasingly specified for erection joints because a yard cannot wait for film. MT is the everyday surface method — nearly everything is ferromagnetic — with PT covering the aluminium superstructure and non-magnetic fittings. VT under formal acceptance criteria carries survey work, and RT persists in new construction where a permanent image is contractually required. A maritime training plan front-loads VT and MT, then builds UT depth, because that is the order the work arrives in.
The governing regime
On the naval side, work answers to NAVSEA technical publications with qualification requirements layered over SNT-TC-1A — yards building or repairing naval vessels run some of the most tightly audited certification programmes in US industry. On the commercial side, classification societies (ABS above all in the US) set survey and acceptance requirements, and their surveyors expect examination records in class-recognisable form. A technician who understands why the two regimes differ — one is a customer's technical authority, the other an independent certifier — reads drawings and acceptance criteria correctly from day one.
Who employs certified technicians
US shipbuilding concentrates in a handful of yards, each a certification programme of its own: nuclear carrier and submarine construction in Virginia, submarine work in Connecticut, destroyers in Maine, amphibious and surface combatants in Mississippi, commercial and repair work on every coast. Around them sit the repair yards, the marine terminal operators, and the survey companies — all employing certified technicians against the same method set.
How people enter this sector
Routes into yard NDT are unusually structured: the major shipbuilders run apprentice and trainee pipelines that take people with no inspection background, and trade crossover is constant — welders move into examination faster here than anywhere, because the yards already employ them. Veterans, especially from hull and machinery ratings, map directly onto the work.

How training is delivered in San Diego
Atlantis delivers training on-site at employer facilities — your equipment, your procedures, your Written Practice — under ASNT Level III oversight. We do not operate walk-in classrooms, and say so plainly: for a company qualifying technicians, on-site delivery is the stronger model, and for individuals, cohorts form around employer demand.

Maritime NDT training in San Diego: the short answer
Short answer: Atlantis NDT trains San Diego ship-repair contractors, fabricators and technicians to ASNT SNT-TC-1A Level I, II and III in UT, PAUT, TOFD, RT, MT, PT, VT and ET. Theory runs live online or onsite at your facility, practicals run on real specimens under an ASNT Level III, and your employer certifies you under its written practice. Navy repair contracts may add NAVSEA qualification, which the contractor's programme controls.
San Diego's maritime inspection market is shaped more by repair than by new construction. The Navy's Pacific surface fleet, aircraft carriers and submarines are homeported or maintained here, and the private yards and repair firms that service them run a constant cycle of availabilities, each with its own inspection scope, deadlines and audit trail. That rhythm rewards technicians who can move quickly between methods and employers who keep their certification files in order. This section explains how SNT-TC-1A training fits that market, where Navy-specific qualification takes over, and how to get training delivered without pulling a crew off a repair job for a week. There is no Atlantis classroom in San Diego or elsewhere in California; we deliver live online or at your shop.

Maritime NDT work in San Diego Bay
General Dynamics NASSCO is the West Coast's largest new-construction shipyard, building auxiliary and support ships for the Navy alongside commercial vessels, and it also performs repair work. BAE Systems runs a major ship repair yard on the bay. Around them sits a large community of ship repair contractors, many working under the Navy's Master Ship Repair Agreement or Agreement for Boat Repair frameworks, together with the specialist subcontractors who do the welding, machining, coatings and inspection inside each availability.
Demand comes from several Navy installations: Naval Base San Diego on 32nd Street, the largest surface-ship base on the West Coast; Naval Air Station North Island on Coronado, where aircraft carriers are homeported; and Naval Base Point Loma, home to submarines. Federal maintenance organisations manage the repair work and set the technical requirements that flow down to contractors. The result is steady inspection volume in thickness surveys, weld repair acceptance, piping and valve work, and structural repairs on decks, foundations and hull plating.
The county's aerospace and energy manufacturers draw on the same technician pool. Gas turbine production, unmanned aircraft and defence electronics work bring PT, ET, UT and RT demand under aerospace specifications, which is useful to know if you are planning a career that may cross from the waterfront to a manufacturing floor.
Which NDT methods San Diego maritime work uses, and under which rules
This table is context for planning training. The contract, the work item and the purchase order always define the code, edition and acceptance clause.
| Method | Maritime application in San Diego | Code or standard usually cited |
|---|
| UT (Level I, II, III) | Thickness surveys on hull, tank and piping during availabilities; shear-wave examination of repair welds | MIL-STD-2035 for naval acceptance; ABS rules for commercial; ASME V |
| PAUT | Encoded weld examination and corrosion mapping where permitted by the contract | Contract technical requirements; ASME V Article 4 |
| TOFD | Flaw sizing on thick welds in new construction and commercial repair | ASME V; customer specification |
| RT | Piping and pressure-boundary welds requiring a permanent image | MIL-STD-2035; ASME V; B31.1 or B31.3 piping codes |
| MT | Crack detection on steel repair welds, back-gouges and structural members | MIL-STD-2035; AWS D1.1; ASME V Article 7 |
| PT | Aluminium superstructures and fittings, stainless and copper-nickel piping, non-magnetic valve bodies | MIL-STD-2035; ASME V Article 6 |
| VT | Visual acceptance of every repair weld and fit-up; first method in any job | MIL-STD-2035 visual criteria; AWS D1.1 |
| ET | Heat-exchanger and condenser tubing; surface checks on non-ferrous parts | Customer specification |
Method spotlight: PT and UT thickness. Aluminium content in modern ships and the volume of copper-nickel and stainless piping keep PT unusually busy in San Diego, and almost every availability starts with UT thickness surveys to define the repair scope. A technician with solid PT and UT thickness skills at Level II is useful from the first week of an availability.
Which certification scheme San Diego maritime employers expect
Atlantis trains to ASNT SNT-TC-1A. The rest of this table describes what employers may require on top, not something we provide.
| Scheme | Who in San Diego requires it | Does SNT-TC-1A training fit? |
|---|
| ASNT SNT-TC-1A (employer-based) | Commercial repair yards, fabricators, inspection firms, many subcontractors | Yes. This is what we train to, and your employer certifies you under its written practice. |
| NAVSEA T9074-AS-GIB-010/271 | Contractors performing NDT on Navy ship work where the contract invokes it | As a foundation. Naval qualification and certification run through the contractor's NAVSEA-compliant programme; a commercial course does not grant it. |
| Naval nuclear and submarine-specific requirements | Work on submarines and nuclear-powered carriers' controlled systems | No. These are programme-controlled qualifications. |
| Class society expectations (ABS and others) | Commercial vessels repaired or built under class | Usually yes, subject to the yard's approved procedures and surveyor acceptance. |
| NAS 410 / EN 4179 | Aerospace manufacturers in the county | Partly. Aerospace employers certify under their own NAS 410 written practice with a responsible Level 3. SNT-TC-1A theory is a foundation; we do not offer NAS 410 certification. |
The practical takeaway for a San Diego technician: an employer-certified SNT-TC-1A Level II in VT, MT, PT and UT is the most portable credential on the waterfront, and your Navy-contract employer will layer NAVSEA qualification over it where the work requires.
The SNT-TC-1A certification path for San Diego technicians, step by step
- Your employer's written practice. Each employer writes its own procedure setting training, experience, exams and certification authority. See written practice development if yours needs one.
- Formal training. Theory in the method and level. Recommended minimum hours are listed in our training requirements matrix; the written practice sets the actual figure.
- On-the-job experience. Logged, supervised time on real work. Repair availabilities generate plenty of it; the challenge is documenting it properly.
- Examinations. General, specific and practical exams administered and graded by a Level III, with the practical on real specimens.
- Vision examination. Near-vision and colour contrast checks on the written practice's schedule.
- Employer certification. Signed by your employer and valid under that written practice.
- Recertification. At the interval your written practice defines.
For the whole scheme, see SNT-TC-1A training and certification.
Radiation licensing and port access for San Diego RT crews
California is an NRC Agreement State, and the California Department of Public Health's Radiologic Health Branch licenses radioactive materials and registers X-ray equipment. California also issues its own industrial radiographer certificates under Title 17 of the California Code of Regulations, so a radiographer working in the state needs the CDPH certification in addition to the employer's NDT certification. An RT method course from any provider does not by itself satisfy the state requirement. Your company's radiation safety officer will specify what is needed.
Access is the other practical hurdle. Navy installations require base access credentials arranged through the employer, and commercial marine terminals regulated under the Maritime Transportation Security Act require a TWIC for unescorted access. If you want onsite training inside a controlled area, raise it at quote stage; it is often simpler to run the practical block at your own shop.
How San Diego crews can take the training
- Live online theory. Instructor-led sessions on Pacific time with recorded review, scheduled around shifts. See NDT training online.
- Onsite at your facility. A Level III runs the course at your shop with your equipment and procedures. Ideal between availabilities, and the best preparation for a prime-contractor or Navy audit because the training uses the procedures the auditor will review.
- Scheduled cohorts. Block courses quoted per cohort. We do not run a training centre in California.
Repair contractors live by the availability schedule, so we book onsite training into the gaps between jobs. Ask about onsite training for your San Diego crew and send us your quiet windows.
A training plan for a San Diego repair contractor
Repair contractors rarely need every method at once. A plan that fits the way availabilities actually run usually looks like this. Start with VT for every welder-inspector and QA hand, because visual acceptance comes first on every repair weld and a shortage of qualified VT people slows an entire job. Add MT and PT next, matched to the materials in your normal scope: steel structures and foundations for MT, aluminium, stainless and copper-nickel for PT. Then build UT in two stages, thickness gauging first because it drives scope definition at the start of each availability, then shear-wave weld examination for repair acceptance. PAUT and TOFD come last and only for the technicians who will use them, since they demand more experience and the contract has to permit them.
Spreading that plan across a year, in short onsite blocks between availabilities and live online theory in the evenings, keeps the crew working while it upgrades. It also produces a steady stream of documented training and experience hours, which is what your Level III needs to certify people without delay when a new contract arrives.
What a San Diego employer receives from an onsite course
Each technician leaves with a training record listing method, level, hours, dates, course outline and instructor; graded exam records where Atlantis administers exams under your written practice; a description of the practical specimens; and a short note on any gaps between your procedures and the work items or codes you inspect to. The records are designed to drop straight into certification files so that your Level III can sign certifications and an auditor can trace every hour.
Level III services and written practices for San Diego repair contractors
Small and mid-size repair subcontractors often discover during a contract award or audit that their NDT programme has gaps: a written practice copied from another firm, missing practical exam documentation, lapsed vision tests, or procedures that do not match the work item. We provide written practice development, procedure review, exam administration and ongoing Level III support, and multi-method programmes through corporate NDT training and maritime corporate training. Local consulting is described on maritime NDT consulting in San Diego, and Level III exam preparation is covered on ASNT Level III training in San Diego. Book a Level III consultation if your programme needs a review.
Practise before the practical exam
The Practical NDT 3D simulator lets trainees practise 12 methods in five environments, including a welding workshop, an NDT lab and a storage tank. It builds familiarity with set-up and scanning between theory sessions. It is practice only and never replaces the practical exam on real specimens.
Your instructor
Training is led by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT, who sets course content, administers and grades examinations where your written practice assigns that role to Atlantis, and reviews employer written practices.
Local NDT training options compared
- Employer and shipyard programmes. The large yards and Navy-contract firms train and qualify their own inspection staff under naval requirements. For a career inside those programmes, apply directly.
- Southern California NDT schools. Private schools in the Los Angeles and Orange County area run fixed-date classroom courses, and some Los Angeles programmes focus on aerospace NDT. They suit individuals who can commute or travel for a block course.
- National online providers. Several schools sell self-paced online theory. Check whether your employer's written practice accepts self-paced hours before buying.
- Atlantis NDT. Best for repair contractors, fabricators and inspection firms that want instructor-led SNT-TC-1A training live online or onsite with Level III and written-practice support.

Frequently asked questions about maritime NDT training in San Diego
How do I get NDT certified in San Diego?
Work for or be sponsored by an employer with an SNT-TC-1A written practice, complete formal training and logged experience, pass the general, specific and practical exams under a Level III, and pass the vision test. Your employer signs the certification.
Can I take NDT training online in California?
Yes, for theory. Practical training and exams are performed on real specimens, onsite at your employer or in a scheduled block.
Does Atlantis provide NAVSEA certification for ship repair?
No. NAVSEA qualification is administered within the contractor's NAVSEA-compliant programme. Our SNT-TC-1A training is the foundation many contractors build it on.
How long does UT Level 2 training take?
It depends on your employer's written practice and your existing experience. Recommended minimums are in our training requirements matrix. Logged experience usually takes longer than the classroom part.
Do I need a licence for radiography in California?
Yes. California requires industrial radiographers to hold a state-issued certificate from CDPH under Title 17, and the company must hold a licence or registration for its sources or X-ray equipment.
What does maritime NDT training cost in San Diego?
Quote on request. Cost depends on method, level, number of trainees, online or onsite delivery and any Level III services. Request a quote and we reply within one business day.
Is ASNT certification recognised by San Diego ship repair employers?
Yes for commercial and most subcontract scope. Navy contracts that invoke NAVSEA requirements add their own qualification on top.
Can I use the GI Bill or WIOA funding?
Only at approved schools and programmes, and Atlantis does not claim that approval. San Diego has many transitioning service members; check with the VA, your base transition office or a local America's Job Center of California. Employer-paid training is the more common route in NDT. See veterans transitioning into NDT.
I was a Navy hull technician. Does that experience count?
Possibly toward on-the-job experience if it is documented and your new employer's written practice accepts it. Bring records of any inspection work you performed.
Which NDT method is most in demand on the San Diego waterfront?
UT thickness and VT start almost every repair job, with MT and PT close behind. Building all four to Level II gives you the widest options.
Is there an NDT training centre in San Diego?
Atlantis does not operate one. We deliver live online and onsite at employer facilities.
How do I prepare for the written exams?
Review your employer's procedures and use mock questions such as our UT Level 2 practice questions.
