NDT Simulator and Hands-On Practice in Seattle

Seattle's NDT workforce lives in two worlds at once. On one side is aerospace: commercial airplane final assembly in Renton and Everett, a dense chain of machining, composite and component suppliers through the Kent valley and south King County, and maintenance and cargo operations at King County International Airport, better known as Boeing Field. On the other side is the water: shipyards and dry docks on Harbor Island and Lake Union, the North Pacific fishing fleet that calls Fishermen's Terminal home, the state ferry system, and the naval shipyard across the Sound in Bremerton. Both worlds depend on inspectors who can find a crack, a disbond or a lack-of-fusion flaw reliably, and both value inspectors who can move between methods. 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 environment where you log in from a browser or app, work realistic jobs in the Aircraft Hangar, Welding Workshop and other environments, and receive instant scored feedback. It serves a trainee learning eddy current for the first time and a seasoned technician keeping phased array skills sharp between contracts.

Why Hands-On NDT Practice Matters in Seattle's Aerospace and Maritime Sectors

Aerospace inspection is exacting. Airframe structures, fittings and composite parts are inspected to detailed procedures with small acceptance limits, and an inspector's findings feed directly into airworthiness decisions. Eddy current around fastener holes, ultrasonic inspection of composite laminates and bonded structure, and penetrant inspection of machined and forged parts all depend on consistent technique: probe handling, scan speed, reference standard selection and careful interpretation. Aerospace employers in the Seattle area typically operate to written practices influenced by standards such as NAS 410, and they expect inspectors to perform consistently every shift. Yet many technicians specialise narrowly, and when production shifts or a new part family arrives, they may be asked to use a method they have not practised in some time.

Maritime inspection has a different rhythm. Fishing vessels come back to Seattle for repairs and refits in the off-season, ferries rotate through maintenance periods, and shipyard work arrives project by project. Inspectors may do hull thickness gauging one week, weld inspection on a new deckhouse the next, and nothing technical for a fortnight after that. In both sectors, specimens are scarce. Aerospace parts with real flaws are controlled, and flawed weld coupons are costly and often locked in company labs. Practical NDT fills the gap by giving Seattle technicians a place to practise between shifts, contracts and seasons, without taking a part off a production line or tying up a lab bench.

Methods You Can Practice: Ultrasonic, Phased Array and Eddy Current Simulator Scenarios

Practical NDT covers 12 methods: PT, MT and VT on the surface side; contact UT, PAUT, TOFD and RT on the volumetric side; eddy current and MFL on the electromagnetic side; plus LRUT guided-wave screening, IRIS for heat-exchanger and boiler tubes, and PMI for alloy verification.

For Seattle's aerospace community, the Aircraft Hangar environment is the natural home. Its 54 jobs focus on airframe and component inspection. Eddy current scenarios cover surface and near-surface crack detection in aluminium structure and around fastener holes, where probe selection, lift-off control and impedance-plane interpretation decide whether a small crack is found. UT jobs reinforce systematic scanning of laminates and metallic parts, and PT and MT jobs build the discipline of preparation, dwell, development and interpretation. VT scenarios sharpen attention to corrosion, damage and workmanship.

For maritime and fabrication inspectors, the Welding Workshop offers 52 jobs on weld coupons and fabrication joints. Contact UT, PAUT and TOFD scenarios let you rehearse beam angle selection, coverage planning and flaw sizing on butt and T-joints of the kind found in hull and deckhouse structure. The NDT Lab environment, with 52 jobs on bench specimens and reference blocks, is the place to get calibration and fundamentals right. RT practice concentrates on image interpretation, so you can learn to distinguish porosity, slag and incomplete penetration without any radiation exposure.

Built for Every Skill Level

New trainees in Seattle come from aviation maintenance programmes, the military, welding schools and shop-floor roles at aerospace suppliers. Practical NDT gives them 33 guided lessons that build fundamentals one method at a time: what each technique can detect, how equipment is configured, how reference standards work, and how to recognise a relevant indication. Every attempt is scored and explained, so trainees develop correct habits early and can repeat difficult steps as often as they need.

Working technicians use the platform to run rare-defect refreshers between assignments. An aerospace ET inspector who usually sees clean parts can drill small cracks at fastener holes until detection is automatic. A maritime UT technician who mostly does thickness gauging can rehearse weld flaw characterisation and sizing before a new-construction job. Because the platform adapts difficulty, it continues to stretch experienced users rather than repeating what they already know.

Level IIIs, inspection supervisors and training leads can build and assign scenario sets, benchmark crews objectively on identical jobs, and find coverage gaps across a team. That makes it easier to decide who is ready for a new part family or a new contract, and to target refresher training where it will help most. 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 NDT Practical Exam Preparation

Practical NDT is a practice and readiness tool, not a certification. It does not grant any level of qualification, and it does not replace the practical examination on real specimens that ASNT SNT-TC-1A requires through an employer's written practice. Under SNT-TC-1A, the employer defines training, experience and examination requirements, and practical exams are taken on actual specimens with actual equipment. A simulator score cannot substitute for that.

Where Practical NDT helps is before and after the formal steps. For NDT practical exam preparation, trainees can rehearse the full sequence of an inspection until it is familiar. After certification, technicians can keep skills fresh between assignments so recertification and new work are less stressful. Employers can use the platform as one part of an in-house programme alongside classroom instruction, supervised experience and formal exams. Atlantis provides formal NDT training and certification support and consulting, and Practical NDT is designed to complement it. Seattle aerospace employers may also require written practices aligned with NAS 410, and naval and marine employers may follow customer-specific requirements; those are local market context your employer will define, and Practical NDT helps you practise the techniques underneath them.

Seattle's NDT Landscape: Airplane Assembly, Suppliers, Shipyards, Ferries and Fleets

Commercial aerospace is the largest single driver of NDT demand in the Seattle area. Airplane final-assembly plants in Renton and Everett anchor a regional supply chain that includes machining, composite fabrication, bonding, forging and assembly companies across King and Snohomish counties. Inspection at those sites leans on UT for composites, ET and PT for metallic structure, and careful VT at every stage. The Aircraft Hangar environment and the NDT Lab mirror much of that work, and they give inspectors a way to practise techniques that production schedules rarely leave time for.

The maritime economy is the second driver. Shipyards and dry docks on Harbor Island and Lake Union build and repair vessels ranging from fishing boats and tugs to ferries and government ships. Fishermen's Terminal serves the North Pacific fishing fleet, whose vessels return for repairs and refits between seasons. The Washington State Ferries system operates vessels that need regular structural inspection. Across Puget Sound, Puget Sound Naval Shipyard in Bremerton performs maintenance on Navy ships and submarines, and its demand for skilled inspectors ripples through the regional labour market. Weld inspection, hull thickness gauging and corrosion assessment are the core tasks, which is where the Welding Workshop and PAUT and TOFD practice fit.

Energy infrastructure adds a third layer, including hydroelectric dams operated by the city's electric utility, fuel terminals and port cranes. For radiography, Washington is a Nuclear Regulatory Commission Agreement State, and the Washington State Department of Health Office of Radiation Protection licenses industrial radiography and requires third-party radiographer certification. Practical NDT keeps RT practice entirely virtual, so you can rehearse interpretation without a source or licence question.

Washington Radiography Rules and Aerospace Written Practices: What Seattle Inspectors Should Know

Two sets of rules shape day-to-day NDT work in Seattle more than any other: the state's radiation protection requirements for radiography, and the written practices that aerospace and marine employers use to qualify their inspectors. Understanding both helps explain where a simulator fits and where it does not.

On the radiation side, Washington regulates radioactive materials under its agreement with the Nuclear Regulatory Commission. The Washington State Department of Health Office of Radiation Protection handles radioactive materials licensing and inspection, X-ray registration and inspection, and related programmes, with headquarters in Tumwater and field offices in Spokane and Richland. A company that wants to perform industrial radiography with sealed sources applies for a specific industrial radiography licence, and the department's guidance notes that copies of each radiographer's third-party certification are required and that the licensee must keep required records at an in-state permanent address. The department also stresses how hazardous radiography sources are if mishandled. For an individual technician, that means real radiography experience comes only through a licensed employer, under its radiation safety programme, with appropriate training and supervision. It also explains why so many Seattle technicians review radiographs far more often than they expose them.

That is exactly where Practical NDT is useful. Because RT in the platform is image interpretation only, inspectors can practise recognising porosity, slag, incomplete penetration, lack of fusion and cracking on weld images as often as they like, with no source, no exposure and no licence involved. What they cannot do in the simulator is gain the supervised radiography experience or radiation safety qualification the state and their employer require. Those stay firmly in the real world.

On the qualification side, aerospace employers in the Puget Sound region typically run written practices influenced by NAS 410, while many marine and industrial employers follow ASNT SNT-TC-1A. Either way, the employer defines training hours, experience requirements and examinations, including a practical exam on real parts or specimens. Aerospace written practices also tend to specify method and technique detail closely, and inspectors are often qualified to specific part families or procedures. When a production change introduces a new part or a new technique, an inspector may need to demonstrate proficiency again.

A sensible Seattle approach is to use the simulator for the parts of that journey that benefit from repetition: rehearsing eddy current around fastener holes before a new structural inspection task, drilling UT scanning discipline on laminate-style parts, or refreshing weld UT and PAUT before a shipyard contract. The Level III can then use benchmark results to decide who needs extra supervised time before the formal demonstration. The simulator builds readiness; the employer's written practice and the real practical exam decide qualification.

Bringing Practical NDT to Your Seattle Team

Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and Seattle's mix of aerospace and maritime work makes it a natural fit. A typical rollout begins with a demo in the environments that match your work: the Aircraft Hangar and NDT Lab for aerospace manufacturers, suppliers and maintenance shops, and the Welding Workshop for shipyards and fabricators. From there, a Level III or training lead can set up trainee scenario sets, refresher sets for technicians returning from other assignments, and benchmark sets to compare inspectors objectively before a new programme or contract starts.

Frequently Asked Questions

Does Practical NDT replace the practical certification exam?

No. Practical NDT is a practice and readiness tool only. ASNT SNT-TC-1A places certification under the employer's written practice, and practical exams must be taken on real specimens. The simulator helps you prepare and stay current, but it does not certify you or replace any required exam.

What experience level is it for?

All levels. New trainees use 33 guided lessons for fundamentals, working technicians use rare-defect refreshers between assignments, and Level IIIs and supervisors build and assign scenario sets, benchmark crews objectively and identify coverage gaps. Difficulty adapts as you improve.

Can inspectors who work across both aerospace and marine jobs use one platform?

Yes, and that is one of the reasons it suits Seattle. The same login gives access to the Aircraft Hangar for airframe and component work, the Welding Workshop for hull and structural welds, and the NDT Lab for calibration and fundamentals. An inspector who moves between a supplier's composite line and a shipyard contract can keep both skill sets current, and a Level III can track progress across both environments in one place.

Is there aerospace-specific practice for Seattle inspectors?

Yes. The Aircraft Hangar environment has 54 jobs focused on airframe and component inspection, including eddy current, UT, PT and VT practice. It does not replace employer-specific qualification to NAS 410 based written practices, but it gives you a place to rehearse the techniques those programmes rely on.

Can maritime and shipyard inspectors use it too?

Yes. The Welding Workshop contains 52 jobs on weld coupons and fabrication joints, with UT, PAUT, TOFD, MT, PT, VT and RT interpretation scenarios that match hull and structural weld inspection. Thickness and corrosion practice is available in the Oil and Gas Site and Storage Tank environments.

Can I get radiography experience for a Washington licence through the simulator?

No. RT in Practical NDT is image interpretation practice only, with no source involved. Real radiography experience, radiation safety training and any third-party radiographer certification required for Washington work must come through a licensed employer and its radiation safety programme. The simulator helps you become a stronger film or digital image interpreter, which is valuable, but it does not count toward licensing or certification requirements.
