NDT Simulator and Hands-On Practical Training in Savannah

Few mid-sized American cities pack as many different kinds of inspection work into one river corridor as Savannah. Business jets are designed, built and maintained at the airport. One of the busiest container ports in North America moves cargo through cranes, wharves and rail yards that all need structural inspection. Five miles downstream, the Elba Island terminal liquefies and ships natural gas. And west of the city, new automotive and battery manufacturing is reshaping Bryan County. Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and Practical NDT brings that portal to Savannah’s inspectors: an immersive, 3D, game-like platform where you log in from a browser or the app and work realistic jobs in an aircraft hangar, a welding workshop, a storage tank, a process plant and an NDT lab. Twelve methods, 33 guided lessons and adaptive scenarios mean a new trainee and a seasoned Level II can both get real value from it, at their own pace, without booking a single specimen.

Why Hands-On NDT Practice Matters on the Savannah River Corridor

The defining feature of NDT work around Savannah is variety. A contract technician in Chatham County might spend one month on airframe components, the next on crane and wharf structure at the port, and the next on piping and tank work at an industrial site along the river. Each of those jobs calls on different methods and a different eye. Eddy current on an aluminium skin has little in common with ultrasonic thickness mapping on a carbon-steel tank shell, and the technician who is excellent at one can be rusty at the other simply because months have passed.

That is the core problem Practical NDT addresses: skills perish when they are not used. Pattern recognition for a particular defect in a particular geometry fades quietly, and nobody notices until the indication is missed. Traditional refresher practice depends on specimens, reference blocks and lab time, all of which are limited, and on-site practice is rarely possible on an operating LNG facility, a working container terminal or a customer’s aircraft.

There is a safety dimension, too. Liquefied natural gas plants handle cryogenic fluids and flammable inventories; aircraft carry passengers; port cranes lift loads over people and equipment. Inspectors in these settings need to be proficient on day one of an assignment, not partway through it. A simulator lets technicians rehearse the job, make their mistakes where they cost nothing, and arrive on site with their judgement already warmed up. For employers, it offers an objective way to see who is ready for which kind of work before the crew is deployed.

Mapping Savannah’s Industries to Practical NDT Environments

Practical NDT has five workplace environments, and Savannah is one of the rare places where almost all of them map directly to local work.

The Aircraft Hangar, with 54 jobs, fits the business aviation cluster at Savannah/Hilton Head International Airport. Airframe and component inspection scenarios exercise eddy current, visual, penetrant and ultrasonic techniques on the kind of structure and fittings that production and service technicians handle.

The Storage Tank environment fits the LNG terminal, fuel and chemical tank farms along the river, and port-side bulk storage. It lets inspectors run UT shell thickness surveys and MFL floor screening on a full-size virtual tank, practising grid layout, coverage and interpretation of wall loss.

The Oil & Gas Site, with 73 jobs, covers weld inspection, corrosion assessment, tube inspection and screening practice in a process plant setting. That is relevant to gas processing, chemical and industrial sites on the river and to inspectors who travel to Gulf Coast work.

The Welding Workshop, with 52 jobs of weld coupons and fabrication joints, fits the heavy fabrication behind port infrastructure, new manufacturing plants in Bryan and Effingham counties, and structural steel work across the region. The NDT Lab, also 52 jobs, is where everyone builds and refreshes fundamentals on bench specimens and reference blocks.

Methods You Can Practise in the Simulator

Practical NDT covers twelve methods. The surface group is PT, MT and VT. Penetrant scenarios on aerospace alloys teach dwell, removal and interpretation; magnetic particle scenarios on welds and ferromagnetic components cover field direction, particle application and relevant versus non-relevant indications; and visual scenarios reinforce the discipline that underpins every other method.

The volumetric group is contact UT, PAUT, TOFD and RT. The ultrasonic testing simulator covers straight and angle beam work, calibration, sensitivity and sizing. The phased array simulator lets technicians set up sector and linear scans on welds and interpret indications in a way that mirrors field practice. TOFD scenarios build familiarity with diffraction signals and the characteristic patterns of planar and volumetric flaws. Radiography scenarios teach exposure logic and image interpretation with no source involved.

The electromagnetic group is ET and MFL, with eddy current central to aircraft work and MFL central to tank floor screening. Finally, the advanced group is LRUT guided-wave screening, IRIS internal rotary UT and PMI. LRUT scenarios cover screening long pipe runs for corrosion; IRIS covers heat-exchanger and boiler tubes; and PMI covers alloy verification, which matters wherever stainless and alloy piping must be confirmed before service, including in cryogenic and chemical systems.

Every job is scored instantly on setup, coverage, detection, characterisation and false calls, so repetition turns into measurable improvement.

Built for Every Skill Level

New trainees start with the 33 guided lessons, which step through the principles and practical sequence of each method. The early scenarios are forgiving and explanatory; later ones remove the prompts. For employers taking on apprentices from local welding and aviation maintenance programmes, this is a structured way to build confidence before trainees shadow real inspections.

Working technicians use rare-defect refreshers between assignments. A technician moving from aircraft work to a tank survey can spend an hour on wall-loss mapping and MFL floor indications first; one heading to a fabrication job can drill lack of fusion, porosity and cracking in PAUT and TOFD. The point is to keep rare but critical indications familiar.

Level IIIs and team leads can build and assign scenario sets, benchmark crews objectively, and see where coverage gaps exist, for example a crew that is strong on UT thickness but weak on angle beam weld interpretation. The scenario library was designed by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT, who also leads Atlantis training.

How It Complements Formal ASNT Training

Practical NDT is a practice and readiness tool. It is not a certification and it does not replace the hands-on practical examination on real specimens required by an employer’s written practice under ASNT SNT-TC-1A. Under that framework, the employer certifies its personnel after documented training, experience, and written and practical examinations with real equipment on real parts. The simulator does not grant a level and should never be presented as doing so.

What it does is prepare people properly. Candidates can rehearse the full sequence of an NDT practical exam, from calibration through scanning to reporting, until the process is second nature. After certification, the same platform helps them stay proficient during quiet periods. Atlantis offers formal NDT training and certification support aligned to SNT-TC-1A, and Practical NDT is designed to sit alongside that training, not in place of it. Savannah employers in aerospace may also require qualification under aerospace standards such as NAS 410, and marine or port clients may reference other schemes; those are local market requirements, and the simulator is simply practice that supports whichever programme applies.

Savannah’s Sector Anchors: Business Jets, Containers, LNG and New Manufacturing

Savannah has been home to a major business-jet manufacturer since 1967, and its headquarters campus at the airport includes manufacturing, research and development, and maintenance and service operations. That has made Savannah the leading aerospace centre in coastal Georgia and built a deep local workforce of airframe, composite and inspection specialists, along with a supply chain of machine shops and component suppliers.

The Port of Savannah, operated by the Georgia Ports Authority, includes Garden City Terminal, described by the authority as the largest single-operator container terminal in North America. Container cranes, wharf structures, straddle carriers, rail interchange and warehousing all create steady demand for structural weld inspection, fatigue crack detection and corrosion assessment in a humid, salt-laden environment.

Downriver, the Elba Island LNG terminal on Elba Island in Chatham County began as an import and regasification facility and was expanded, with the work completed in 2020, to liquefy and export natural gas. LNG facilities involve cryogenic piping, large storage tanks and alloy materials, which is exactly the territory of UT, PMI, weld inspection and tank survey practice.

West of the city, Bryan County has become home to large-scale electric vehicle and battery manufacturing investment, with suppliers spreading across the surrounding counties. New plants bring structural steel, process piping and tooling that need inspection during construction and operation. Pulp, paper and chemical operations along the Savannah River add further demand for tank, piping and pressure vessel work.

For radiography, Georgia is an NRC Agreement State, and the Radioactive Materials Program of the Georgia Environmental Protection Division licenses industrial radiography, including multiple job-site operations. Radiographers working at the port, at fabrication yards or at industrial sites do so under that framework. Practical NDT’s radiography scenarios involve no source at all, so trainees can build exposure and interpretation judgement safely before working under a real licence.

Bringing Practical NDT to Your Savannah Team

There is no hardware to install and no lab to set up. Technicians log in from a browser or the app, which suits a workforce that moves between the airport, the port and industrial sites. A typical Savannah rollout starts with a demo for the Level III or quality lead, then a choice of which environments to prioritise, often the Aircraft Hangar for aerospace teams, the Storage Tank and Oil & Gas Site for energy and terminal work, and the Welding Workshop for fabrication. The lead assigns scenario sets, the crew works through them on their own schedule, and the lead reviews objective results to decide where formal training time should go.

Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience so that inspectors could keep their skills sharp between very different kinds of work.
