NDT Simulator and Practical Training in Kenai and Nikiski, Alaska

On the Kenai Peninsula, the nearest well-equipped NDT lab can be a long drive or a flight away, winter can close roads and cancel classes, and much of the inspection work happens on assets that are decades old and exposed to some of the harshest marine conditions in the country. The industrial corridor north of Kenai, running up through Nikiski along Cook Inlet, holds a crude oil refinery, a long-running LNG plant now being redeveloped as an import terminal, marine docks, tank farms and the onshore end of pipelines serving offshore platforms that have stood in the inlet since the 1960s. Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and Practical NDT is a strong fit for a place where distance, weather and small crew sizes make physical practice hard to organise. It is an immersive, 3D, game-like platform that runs in a browser or app. A trainee or a working Level III can open it in a camp room, an office in Soldotna or a kitchen in Kenai and practise realistic refinery, tank and pipeline inspection jobs with instant scored feedback.

Why Hands-On NDT Practice Matters on the Kenai Peninsula

Inspection in the Nikiski corridor is shaped by age and environment. Much of the infrastructure dates from the early development of Cook Inlet oil and gas, so the inspection agenda is dominated by corrosion: external corrosion and corrosion under insulation on piping exposed to cold, wet, salt-laden air; internal corrosion in process piping and vessels; pitting and wall loss in heat exchangers; and floor and shell deterioration in storage tanks. Welding repair and modification work is constant, and every repair needs inspection before it goes back into service. Cold-weather conditions add their own complications, from couplant behaviour to the simple difficulty of scanning a pipe with gloved hands in a short daylight window.

Crews here are also small, and the same few people cover a wide range of methods. A technician might do thickness surveys one week, help with exchanger tube inspection during a maintenance window the next, and then be asked to screen a long pipe run for corrosion. The hard, uncommon findings, such as a deep isolated pit in a tube, a mixed-up alloy in a repair, or a crack at a weld toe, may only turn up a few times a year. Getting to a lab with flawed specimens to practise those cases usually means a trip to Anchorage or further. Practical NDT lets Kenai technicians keep those skills alive locally, safely and whenever the schedule allows, without consuming specimens and without any radiation exposure for RT interpretation practice.

Which Practical NDT Environments Fit Kenai and Nikiski

Practical NDT is organised into five environments: an NDT Lab with bench specimens and reference blocks, a Welding Workshop with weld coupons and fabrication joints, an Aircraft Hangar for airframe and component inspection, an Oil & Gas Site covering weld, corrosion, tube and screening practice inside a process plant, and a Storage Tank environment for UT shell thickness surveys and MFL floor screening on a full-size tank. For the Kenai Peninsula, the Oil & Gas Site and the Storage Tank environment are the heart of it.

The Oil & Gas Site is the largest environment, with 73 jobs, and it maps closely to refinery and terminal work: corrosion surveys on piping, weld inspection on repairs, exchanger tube inspection with IRIS, alloy verification with PMI and guided-wave screening of long runs with LRUT. The Storage Tank environment covers shell thickness surveys and MFL floor screening, directly relevant to crude and product tank farms and LNG-related storage. The Welding Workshop, with 52 jobs, supports repair and fabrication inspection. The NDT Lab, with 52 bench jobs, is where new local hires should begin, and the Aircraft Hangar is available for the many Alaskans whose work also touches aviation, given how much of the state depends on aircraft.

Methods You Can Practice: Corrosion UT, IRIS, LRUT and Phased Array Simulator

Practical NDT covers twelve methods. Surface methods are PT, MT and VT. Volumetric methods are contact UT, phased array UT, TOFD and RT. Electromagnetic methods are ET and MFL. The platform also includes LRUT guided-wave screening, IRIS internal rotary UT for heat-exchanger and boiler tubes, and PMI for alloy verification. For Kenai’s refinery and terminal work, the most valuable are corrosion-focused. UT thickness scenarios teach the discipline of reliable readings, including how to handle pitted and rough surfaces. IRIS scenarios walk through tube bundle inspection and wall-loss map interpretation, so a technician can tell general thinning from isolated pitting. LRUT scenarios cover screening long pipe runs and deciding where detailed follow-up belongs, which matters on long piping and pipeline sections that are hard to access.

For repairs and new work, the ultrasonic testing simulator covers angle-beam weld inspection, and the phased array simulator lets you set up sectorial scans on weld geometries and characterise lack of fusion, cracking, porosity and slag. TOFD scenarios add diffraction-based flaw sizing. MFL scenarios in the Storage Tank environment cover floor screening. PMI rehearses alloy confirmation on piping components and repair materials. MT and PT scenarios cover surface-breaking cracks on welds and attachments, and RT scenarios build weld image interpretation without scheduling any radiography. VT scenarios reinforce a careful visual, especially important for spotting coating breakdown and corrosion under insulation indicators before instruments come out.

Built for Every Skill Level

New trainees start with 33 guided lessons that cover fundamentals in a logical sequence, with immediate feedback on every setup and scan. On the Kenai Peninsula, where many people move into inspection from operations, maintenance, welding or commercial fishing and marine trades, the ability to learn fundamentals locally rather than waiting for a class in Anchorage is a real advantage.

Working technicians use the platform to refresh rare-defect recognition between assignments. A Level II who has done mostly thickness readings through the winter can rehearse IRIS interpretation before an exchanger job, or practise phased array crack sizing before a repair campaign. Level IIIs and team leads can build and assign scenario sets, benchmark a small crew objectively on identical jobs and identify coverage gaps, which is especially useful when crews rotate and the same Level III is responsible for people who are rarely in the same place at once. The scenario library was designed by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT, who also leads Atlantis training.

NDT Practical Exam Preparation: How It Complements Formal ASNT Training

Practical NDT is a skills-practice and readiness tool. It is not a certification, it does not grant any level, and it does not replace the practical examination on real specimens that ASNT SNT-TC-1A and your employer’s written practice require. Under SNT-TC-1A, your employer’s written practice sets the training, experience and examination requirements, and the practical exam is conducted with real equipment on real specimens under the responsible Level III. No simulator result substitutes for that.

In a remote region, though, preparation matters even more, because every trip to a lab or exam session is expensive and weather-dependent. A candidate who has already rehearsed setups and interpretation many times gets far more out of limited real hands-on time. That is why Practical NDT is positioned as a complement to our NDT training and certification programs. Plant owners in the Nikiski corridor may also expect in-service inspectors to hold industry inspector credentials for piping, vessels or tanks; those are employer requirements and market context only, and Practical NDT does not train toward, administer or certify to them.

The Nikiski Industrial Corridor: Refining, LNG, Cook Inlet and Regulation

The Kenai refinery at Nikiski, on the east shore of Cook Inlet roughly sixty miles southwest of Anchorage across the water, is a crude oil refinery with a capacity in the region of 68,000 barrels per day, supplying fuels to Southcentral Alaska. Nearby, the Kenai LNG plant exported liquefied natural gas to Asia for more than four decades before it was mothballed in 2017. In late 2025, Harvest Alaska completed its purchase of the facility with plans to repurpose it as an LNG import and regasification terminal to help address Southcentral Alaska’s tightening gas supply, with full-scale operation targeted around 2028. Converting an export plant to import service means inspection of existing tanks, piping, docks and process equipment, plus new construction. These facilities are named as industry context only, not as Atlantis customers.

Offshore, Cook Inlet holds seventeen production platforms, most installed in the 1960s, and the great majority now operated by a single company focused on mature fields. Several have stopped producing, and aging subsea pipelines connecting platforms to shore have been a recurring public concern. Keeping that system in safe service, or eventually decommissioning parts of it, relies on corrosion inspection, weld inspection on repairs and careful integrity management of old steel in cold, fast-moving, sediment-laden water.

Regulation shapes radiography here in a specific way. Alaska is not an NRC Agreement State, so licensing and inspection of radioactive materials used for industrial radiography in Alaska fall directly under the U.S. Nuclear Regulatory Commission rather than a state program. That makes source logistics and compliance more involved for small local operators, and it is one more reason RT interpretation practice in a simulator is attractive: technicians can build interpretation skill without any source being shipped, stored or used.

NDT Practice in Kenai Without Travelling for Lab Time

For most Kenai Peninsula technicians, the biggest barrier to regular practice is geography. Flawed specimen libraries and experienced trainers are concentrated in larger cities, and winter travel is unpredictable. Practical NDT removes that barrier for practice. A trainee can work a guided lesson in the evening in Soldotna, a technician on rotation can rehearse IRIS interpretation in camp accommodation, and a Level III in Anchorage can assign scenario sets to a crew spread across the peninsula and review the results remotely.

Employers get visibility they rarely have with dispersed crews. When everyone works the same scenarios, it is clear who reads corrosion data confidently and who needs more supervised time on real equipment before taking on acceptance responsibility. That supports staffing and coaching decisions without replacing the supervised experience and certification steps your written practice already requires.

Frequently Asked Questions

Does Practical NDT replace the practical certification exam?

No. It is a practice and readiness tool. Certification under ASNT SNT-TC-1A follows your employer’s written practice, which includes a practical exam on real specimens with real equipment. Practical NDT helps you prepare and stay current, but it does not certify anyone.

What experience level is it for?

All levels. Trainees use 33 guided lessons, working technicians use rare-defect refreshers between assignments, and Level IIIs and team leads build and assign scenario sets, benchmark crews and find coverage gaps.

Does it work with limited or rural internet?

Practical NDT runs in a browser or as an app. For sites with constrained connectivity, talk to us during the demo about your setup so we can recommend the most practical way to access it for your crew.

Is it relevant to refinery and LNG terminal inspection?

Yes. The Oil & Gas Site covers corrosion surveys, weld inspection, IRIS on exchanger tubes, PMI alloy verification and LRUT screening in a process plant, and the Storage Tank environment covers shell thickness surveys and MFL floor screening.
