NDT Simulator and Hands-On Practice for Erie’s Locomotive and Great Lakes Shipyard Workforce

Erie is Pennsylvania’s only Great Lakes port, and its industrial identity rests on two very heavy products: locomotives and ships. In Lawrence Park, on the eastern edge of the city, one of the largest locomotive plants in North America has been building freight locomotives for over a century. On the bayfront, a shipbuilding and repair yard operates one of only two dry docks on the Great Lakes able to take thousand-foot lake freighters. Around them sits a supply chain of foundries, machine shops, fabricators and plastics manufacturers. All of that work is held together by welds and castings, and all of it depends on inspectors who can find what matters. Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and Practical NDT is that portal: an immersive, 3D, game-like platform, accessed from a browser or the app, where users work realistic inspection jobs with virtual equipment and get instant scored feedback. It serves every skill level, from a trainee who has never set up a flaw detector to a Level III building assessments for a crew. This page explains how it fits Erie’s rail, marine and manufacturing inspection work, and makes clear what it is not.

Why Hands-On NDT Practice Matters for Erie’s Rail and Marine Manufacturing

The locomotive plant in Lawrence Park, opened as a General Electric works and now part of Wabtec since the 2019 acquisition of GE Transportation, is Erie County’s largest industrial site and one of its largest employers. Locomotive manufacturing involves heavy welded underframes and platforms, large structural fabrications, castings, machined rotating components and traction equipment. For inspectors, that means a constant mix of visual weld inspection, magnetic particle testing on welds and castings, ultrasonic testing on thick sections and heavy weldments, and eddy current on machined surfaces and fastener holes. Much of the locomotive supply base — foundries, forges, machine shops — is spread across northwestern Pennsylvania and nearby Ohio and New York, and those shops need the same skills.

On the waterfront, ship repair has a strongly seasonal rhythm. Great Lakes shipping largely pauses in winter, and freighters come in for layup maintenance, steel renewal, repowering and dry docking. The Erie yard, one of only two on the Lakes that can dry dock thousand-foot vessels, sees hull plate replacement, weld repairs, thickness gauging and structural inspection compressed into those months. A technician may spend summer on fabrication work and then face a surge of hull thickness surveys and weld repairs when the fleet comes in.

That seasonality is exactly why skills fade and why practice matters. Real flawed specimens are scarce, calibration blocks are shared across shifts, and nobody wants to learn a new technique on a live hull repair against a sailing deadline. Practical NDT lets inspectors rehearse the methods and defect types they will need, whenever they have time, without consuming specimens or lab time, and without any radiation exposure for RT interpretation practice.

Methods and Environments: an Ultrasonic Testing Simulator for Welds, Castings and Hulls

Practical NDT covers twelve methods — PT, MT and VT for surface work; contact UT, PAUT, TOFD and RT for volumetric work; ET and MFL for electromagnetic inspection; and LRUT guided-wave screening, IRIS internal rotary UT and PMI alloy verification — spread across five workplace environments. For Erie, three environments carry most of the value.

The Welding Workshop, with 52 jobs on weld coupons and fabrication joints, is the natural home for locomotive and ship fabrication inspectors. Users practise angle-beam UT on butt and T-joints, phased array sectorial scans for lack of sidewall fusion and incomplete penetration, TOFD for through-wall sizing, and MT on fillet welds, where the direction of magnetisation relative to a toe crack decides whether it shows up at all. RT interpretation scenarios help inspectors read porosity, slag and cracking on images without a source anywhere near the shop.

The NDT Lab, 52 jobs on bench specimens and reference blocks, is where casting and forging inspectors get the fundamentals right: calibration on reference blocks, straight-beam UT for shrinkage and inclusions, attenuation effects on coarse-grained material, and PT and MT on machined surfaces. It is also where a new trainee builds the base before moving into site environments.

The Aircraft Hangar, 54 jobs, is less obviously Erie, but its eddy current scenarios — bolt-hole inspection, surface cracks around fasteners, conductivity checks — transfer directly to machined rail and traction components. The Oil & Gas Site, 73 jobs, adds IRIS and ET on heat-exchanger tubes, corrosion mapping on piping and PMI alloy checks, relevant to plant engineering in local manufacturing and power facilities, and the Storage Tank environment covers UT shell thickness surveys and MFL floor screening for the fuel and bulk-liquid storage that any working port depends on. Thickness surveys learned on the tank shell carry straight over to hull gauging practice.

Built for Every Skill Level

Erie’s inspection workforce includes long-tenured technicians in heavy manufacturing, seasonal marine hands and newcomers from welding programmes. Practical NDT handles all three. New trainees start with 33 guided lessons covering the fundamentals of each method: how to set range and velocity, how to find the exit point and refracted angle, what a proper MT field looks like, and why surface preparation decides a penetrant result. Each lesson ends in a scored job, so progress is visible rather than assumed.

Working technicians use the platform to stay sharp through the quiet part of the year and before the busy part. A marine inspector can refresh hull thickness and weld UT before the winter fleet arrives; a plant inspector can revisit PAUT sizing before a new weld procedure comes in. Rare-defect refreshers and adaptive scenarios mean the platform pushes each user a little past what they already handle comfortably.

Level IIIs and team leads can build and assign scenario sets, benchmark crews objectively against identical defects, and identify coverage gaps — which technicians have not practised TOFD recently, or who struggles with geometric reflectors on T-joints. The scenario library was designed by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT, who leads Atlantis training.

How It Complements Formal ASNT Training and the Practical Exam

Plainly stated: Practical NDT is a practice and readiness tool. It does not grant certification and does not replace the practical examination on real specimens that ASNT SNT-TC-1A and an employer’s written practice require. Under SNT-TC-1A, each employer certifies its own NDT personnel according to its written practice, which sets training hours, experience requirements and general, specific and practical examinations. The practical exam uses physical specimens and real equipment and is graded by a qualified examiner.

What a simulator adds is preparation. For NDT practical exam preparation, candidates can run many jobs of the type they will be examined on, see their mistakes immediately, and practise again without needing another specimen or supervisor. Employers get objective readiness data to decide who is ready for the formal exam. Experienced technicians use it to keep methods fresh between assignments. The formal route remains the formal route; Practical NDT helps people arrive better prepared. For structured coursework and certification preparation, see Atlantis NDT training and certification.

Some Erie manufacturers supplying international rail or marine customers may be asked by those customers for other qualification schemes. That is contractual market context only; Atlantis frames its training and Practical NDT around ASNT SNT-TC-1A.

Erie’s Industrial Map: Lawrence Park, the Bayfront and the Supplier Belt

Erie’s geography explains its inspection needs. Lawrence Park, a township that grew up around the locomotive works and recently marked a century as a community, remains dominated by that plant, with a unionised manufacturing workforce and decades of locomotive-building know-how. The bayfront along Presque Isle Bay is where the port, the shipyard and its dry dock sit, protected from the open lake by the Presque Isle peninsula. The commercial port handles bulk and project cargo, and the shipyard handles new construction, repair, conversion and repowering of Great Lakes vessels. These facilities are named here as industry context only; none is presented as a Practical NDT customer.

Beyond the lakefront, the region’s supplier belt includes foundries, forging and machining shops and a well-known plastics and tooling cluster. Plastics moulding relies on precision steel tooling, which brings its own inspection needs, but the heavier NDT demand comes from castings, weldments and machined rail components. Interstate 79 and Interstate 90 link Erie to Pittsburgh, Cleveland and Buffalo, so inspectors often work across state lines.

Radiographic work in Erie falls under Pennsylvania’s radiation control framework: Pennsylvania is an NRC Agreement State, and the Department of Environmental Protection’s Bureau of Radiation Protection licenses radioactive materials, including industrial radiography sources. That regulatory overhead is one reason employers welcome RT interpretation practice that needs no source at all.

Hands-On NDT Training in Erie and NDT Training Online in Pennsylvania

Erie is a long way from the big training centres of Pittsburgh or Philadelphia, which is why many people search for NDT training online in Pennsylvania or virtual NDT training they can do locally. Online theory prepares candidates for written exams, and supervised hands-on training on real equipment builds the practical skill and hours the written practice demands. Practical NDT is the flexible middle layer: hands-on style practice that can be done from home in Millcreek, Harborcreek or Fairview, on the night shift break at the plant, or in a hotel during a job elsewhere on the Lakes. Then the scarce bench time and field supervision provided by the employer can go into the things only real equipment teaches.

Bringing Practical NDT to Your Erie Team

Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and a live walkthrough is the fastest way to see how it would work for an Erie crew. Demos for Erie teams typically focus on the Welding Workshop and NDT Lab for locomotive, casting and fabrication inspectors, plus thickness-survey scenarios for marine repair crews preparing for the winter fleet, and the Level III tools for assigning and reviewing scenario sets. Rollouts usually start with a pilot group and one lead choosing scenarios, then widen once the crew is comfortable with the scoring and feedback. Pricing is quoted on request based on team size; there is no public price list.

Request a Practical NDT demo for Erie. Marine repair supervisors can ask about pre-season refreshers for winter layup crews, and manufacturing quality teams can ask about weld and casting scenario sets. General questions can go to info@atlantisndt.com.

Frequently Asked Questions

Does Practical NDT replace the practical certification exam?

No. ASNT SNT-TC-1A certification is granted by the employer under its written practice, and the practical exam must be taken on real specimens with real equipment. Practical NDT helps people prepare and stay sharp; it does not certify anyone.

What experience level is it for?

All levels. Trainees follow 33 guided lessons, working technicians use rare-defect refreshers and adaptive scenarios, and Level IIIs build and assign scenario sets, benchmark crews objectively and find coverage gaps.

Is it relevant to Great Lakes ship repair?

Yes, as practice. Weld UT, PAUT, TOFD and MT scenarios in the Welding Workshop cover the weld repairs common in hull and structural work, and UT thickness survey scenarios on the Storage Tank shell build the same scanning discipline used in hull gauging. It supplements, but does not replace, any qualification required by your yard or classification requirements.

Can casting and forging inspectors use it?

Yes. The NDT Lab environment focuses on bench specimens and reference blocks, suited to straight-beam UT on castings and forgings, plus MT and PT on machined surfaces. Eddy current scenarios in the Aircraft Hangar environment also transfer to machined components.

Do we need a lab or special equipment?

No. Practical NDT runs in a browser or the app, with no specimens, calibration blocks or radiation sources consumed, so technicians can practise anywhere with a reasonable computer or device.
