NDT Simulator and Hands-On Practice in Portland

Along the Willamette River in Northwest Portland, a six-mile band of fuel terminals known as the Critical Energy Infrastructure Hub stores most of Oregon's liquid fuel supply. Some of its tanks are more than a century old, and they sit on river soils that geologists expect to liquefy in a major Cascadia earthquake. State law now requires terminal operators to assess the seismic vulnerability of those tanks, and city leaders have proposed rules to reduce storage over time. That alone makes tank and piping inspection a live topic in Portland. Add the 60-acre Swan Island shipyard with its giant floating dry dock, foundries producing large structural castings for aerospace and energy, heavy truck and railcar manufacturing, and the Columbia River hydro system, and you have a city whose NDT needs span storage tanks, ship welds and precision castings. 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 where you log in from a browser or app, practise realistic inspection jobs, and get instant scored feedback. It supports trainees and experienced technicians alike.

Why Hands-On NDT Practice Matters in Portland's Fuel, Shipyard and Casting Sectors

The fuel terminals along the Willamette put storage tank inspection at the centre of Portland's NDT conversation. Tank inspection is a specialised skill: planning UT shell thickness surveys, running MFL floor scans, recognising the difference between product-side and soil-side corrosion, and proving up indications with UT. Much of that work happens during out-of-service inspections, which are scheduled years apart for any given tank. An inspector may go months without scanning a tank floor, then be expected to perform flawlessly when a tank is opened. With seismic assessments and the scrutiny that comes with them, accurate data on shell and floor condition matters more than ever.

Shipyard work at Swan Island follows the arrival of vessels for dry-docking and repair, and inspection demand rises and falls with those projects. Weld inspection on new steel, thickness gauging on existing hulls and structural checks on repaired areas must be done quickly and correctly while a ship is out of the water. Casting inspection is steadier but more demanding: large structural castings for aircraft engines and industrial turbines are inspected with radiography, penetrant and ultrasonic methods to strict standards, and interpretation skills take years to develop.

In all three sectors, physical practice material is scarce. Tank floor sections, flawed ship welds and rejected castings are not available for casual rehearsal, and taking equipment off production work to practise costs money. Practical NDT gives Portland technicians a place to build and maintain skill between jobs, without specimens or lab bookings.

Methods You Can Practice: Storage Tank MFL, Weld PAUT and Casting Interpretation

Practical NDT covers 12 methods: PT, MT and VT for surfaces; contact UT, PAUT, TOFD and RT for volumetric inspection; eddy current and MFL for electromagnetic inspection; and LRUT guided-wave screening, IRIS internal rotary UT for exchanger and boiler tubes, and PMI for alloy verification.

For Portland's terminal inspectors, the Storage Tank environment is the most relevant. It places you in front of a full-size tank to practise UT shell thickness surveys and MFL floor screening, including coverage planning, identifying corrosion patterns and following up indications with UT. The Oil and Gas Site environment, with 73 jobs covering weld, corrosion, tube and screening practice in a process setting, adds piping corrosion surveys, LRUT screening on long pipe runs and PMI alloy verification, all common on terminal manifolds and transfer lines.

For shipyard and fabrication inspectors, the Welding Workshop offers 52 jobs on weld coupons and fabrication joints, with contact UT, PAUT and TOFD for volumetric flaw detection and sizing, plus MT, PT and VT for surface checks. For casting and component inspectors, the NDT Lab environment, with 52 bench specimen and reference block jobs, supports calibration practice and fundamentals, while RT image interpretation scenarios help you learn to recognise porosity, shrinkage, inclusions and cracks without any radiation exposure. The Aircraft Hangar, with 54 jobs, covers airframe and component inspection with eddy current and UT for anyone supporting aviation.

Built for Every Skill Level

Portland's NDT trainees often come from welding programmes, including the maritime welding training centre that Portland Community College operates beside the Swan Island shipyard, as well as from manufacturing, the military and trades. Practical NDT offers them 33 guided lessons that build fundamentals method by method: what each technique detects, how equipment is set up, how reference standards work, and how to plan coverage. Each attempt is scored with specific feedback, so trainees develop correct habits and can repeat difficult steps as often as needed.

Working technicians use rare-defect refreshers between assignments. A tank inspector can rehearse MFL interpretation before an out-of-service inspection. A shipyard UT technician can drill crack characterisation and TOFD sizing before a repair project. A casting inspector who usually reviews radiographs can practise ultrasonic techniques, or vice versa. Adaptive difficulty keeps every user working at the edge of their ability.

Level IIIs and inspection leads can build and assign scenario sets, benchmark crews objectively on identical jobs, and find coverage gaps across the team. That helps when assembling a crew for a tank programme or a dry-dock availability, and when deciding where to focus refresher training. 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 does not replace the practical examination on real specimens that ASNT SNT-TC-1A requires through an employer's written practice. SNT-TC-1A leaves training, experience and examination requirements to the employer, and practical exams are performed on actual specimens with actual equipment. A simulator does not change that.

What the platform offers is better preparation and maintenance. For NDT practical exam preparation, trainees can rehearse the full sequence of an inspection until it feels routine. For working technicians, it keeps skills current between assignments. For employers, it can be one component of an in-house programme, alongside classroom instruction, supervised experience and formal exams. Atlantis offers formal NDT training and certification support and consulting, and Practical NDT is designed to complement it. Portland employers in aerospace castings may also operate written practices aligned with NAS 410, and terminal owners may require separate tank inspector credentials; those are local market context set by employers and owners, and Practical NDT helps you practise the NDT methods underneath them.

Portland's NDT Landscape: The CEI Hub, Swan Island, Castings, Trucks and Hydro

The Critical Energy Infrastructure Hub is the most distinctive NDT story in Portland. Its terminals store and distribute hundreds of millions of gallons of fuel, and analyses have warned that liquefaction and lateral spreading in a major earthquake could rupture many tanks. Under legislation passed in 2022, the Oregon Department of Environmental Quality runs a fuel tank seismic stability programme that requires operators to submit seismic vulnerability assessments. Tank condition data from shell thickness surveys, floor scans and weld inspection feeds into that kind of engineering work, and it is exactly what the Storage Tank environment helps inspectors rehearse.

Swan Island is the second anchor. The 60-acre shipyard, established in World War II, is one of the largest full-service yards on the West Coast and home to what is described as the largest floating dry dock in North America. It repairs and builds vessels and fabricates bridges and steel structures, all of which require weld inspection. Portland is also home to railcar and marine barge manufacturing on the Willamette, the North American headquarters and a manufacturing plant for a major heavy truck maker, and foundries that produce large structural investment castings for aerospace engines and industrial gas turbines, where RT, PT and UT interpretation skills are critical.

Energy infrastructure rounds out the picture. The federal power marketing administration that operates the Columbia River transmission system is headquartered in Portland, and Bonneville Dam and other Columbia hydro projects nearby need penstock, gate and structural inspection. For radiography, Oregon is a Nuclear Regulatory Commission Agreement State, and Oregon Health Authority Radiation Protection Services regulates radiation use, with state rules covering industrial radiographic operators, including on-the-job training requirements. Practical NDT keeps RT practice virtual, so there is no source and no exposure when you practise.

Oregon Rules for Radiography and Fuel-Tank Seismic Work: What Portland Inspectors Should Know

Two regulatory threads run through Portland NDT work in ways that make practice valuable: Oregon's rules for industrial radiography, and the state's attention to the seismic safety of the fuel tanks along the Willamette.

Industrial radiography in Oregon is regulated by Oregon Health Authority Radiation Protection Services, which works to protect Oregonians from unnecessary exposure from X-ray equipment, radioactive materials and other sources. The rules for industrial radiographic operators sit in the Oregon Administrative Rules, chapter 333, division 105. Among other things, those rules set expectations for on-the-job training: before an individual may act as an X-ray radiography machine operator, the registrant must ensure they have had hands-on experience under the supervision of a qualified operator, with a minimum of one month, or 160 hours, of active participation in industrial X-ray work. The rules also define concepts such as cabinet radiography, where the enclosure is shielded so that dose limits for the public are met outside it.

The point for a Portland technician is straightforward. Real radiography experience comes only from supervised work with a registered or licensed employer, and no simulator hours can be counted toward it. What Practical NDT can do is make those supervised hours more productive. A trainee who has already practised recognising porosity, shrinkage, inclusions, lack of fusion and cracking on radiographic images arrives at the job able to focus on setup, safety and technique rather than on basic interpretation. Experienced casting and weld interpreters can use the RT scenarios to keep their eye sharp on less common discontinuities.

The fuel-tank thread is newer. Following 2022 legislation, the Oregon Department of Environmental Quality manages a fuel tank seismic stability programme that requires operators at the Critical Energy Infrastructure Hub to submit seismic vulnerability assessments. City officials have also proposed rules that would require the hub's 11 terminals to cut fuel storage capacity by at least 20 percent by 2036. Seismic assessment is engineering work, not NDT, but it relies on knowing the real condition of tank shells, floors, welds and connected piping. Accurate shell thickness surveys, careful floor screening with follow-up UT, and sound weld inspection all feed that picture.

For Portland tank inspection crews, that raises the value of consistent technique. The Storage Tank environment lets inspectors rehearse shell thickness survey planning and MFL floor screening before a tank is opened, and the Oil and Gas Site covers the piping and manifold corrosion work that surrounds it. A Level III can benchmark tank crews on identical scenarios so that data collected by different inspectors, on different tanks and in different years, is gathered with the same discipline. The simulator does not make anyone a tank inspector or satisfy any regulatory requirement; it helps the qualified people doing the work stay sharp.

Bringing Practical NDT to Your Portland Team

Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and Portland's mix of tank, ship and casting work shows how broadly it applies. A typical rollout starts with a demo in the environments that match your work: the Storage Tank and Oil and Gas Site for terminal operators and tank inspection contractors, the Welding Workshop for shipyards and fabricators, and the NDT Lab for casting and component inspectors. A Level III or training lead can then set up trainee sets, refresher sets before tank programmes or dry-dock periods, and benchmark sets to compare crews objectively.

Frequently Asked Questions

Does Practical NDT replace the practical certification exam?

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

What experience level is it for?

Every level. New trainees follow 33 guided lessons, working technicians use rare-defect refreshers between assignments, and Level IIIs build and assign scenario sets, benchmark crews objectively and find coverage gaps. Difficulty adapts as you improve.

Does it help shipyard welders at Swan Island move into inspection?

It can. Welders already understand joint design and how flaws form, which is a strong foundation for inspection. The Welding Workshop lets them practise finding and characterising those same flaws with UT, PAUT, TOFD, MT, PT and VT, and the 33 guided lessons explain each method from the ground up. Moving into certified inspection work still requires formal training, supervised experience and examinations defined by an employer's written practice under SNT-TC-1A.

Can I practise storage tank inspection for fuel terminals?

Yes. The Storage Tank environment covers UT shell thickness surveys and MFL floor screening on a full-size tank. It helps inspectors prepare for out-of-service inspections, although owner requirements and the applicable tank inspection standards still govern the real work.

Do simulator hours count toward Oregon's radiography on-the-job training requirement?

No. Oregon's rules for industrial radiographic operators require supervised, hands-on experience with real X-ray equipment under a qualified operator, and simulator time is not a substitute. Practical NDT's RT scenarios are image interpretation practice only, with no radiation involved. They can help you get more out of your supervised hours, but the hours themselves must be earned on the job through your employer.

Is it useful for casting and foundry inspectors?

Yes. RT image interpretation scenarios and NDT Lab bench jobs help casting inspectors practise recognising discontinuities such as porosity, shrinkage, inclusions and cracks, and UT and PT scenarios support the other methods used on castings. Employer and customer specifications still define acceptance criteria.
