Practical NDT Training Simulator for the San Francisco Bay Area (Richmond/Martinez)

The refinery corridor of Contra Costa County, running from Richmond on San Pablo Bay east along the Carquinez Strait to Martinez and beyond, is one of the most heavily regulated industrial areas in the country, and it is going through the biggest change in its history. Crude refining continues at major sites, while two neighboring refineries have been converted to renewable diesel and fuels production, and a refinery just across the strait in Benicia stopped refining in April 2026. For inspectors, that means a mix of classic refinery mechanical-integrity work, new equipment and metallurgy in converted units, and decommissioning and repurposing work. 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 you open in a browser or app to practice realistic inspection jobs on piping, heat-exchanger tubes, pressure vessels, storage tanks, welds and structural members. It serves new trainees, working technicians and Level III leads. If you have been looking for an NDT simulator in the Bay Area, or NDT practice for Richmond and Martinez refinery work, this page explains how it fits.

Why Hands-On Practice Matters on the Richmond–Martinez Refinery Corridor

Refinery inspection in Contra Costa County is shaped by some of the strictest process safety rules anywhere. California’s refinery-specific process safety management standard, Title 8 Section 5189.1, applies to petroleum refinery processes and supersedes the general standard for those facilities. On top of that, Contra Costa County’s Industrial Safety Ordinance strengthens the state accidental release prevention program for refineries and chemical plants in the unincorporated county, and the City of Richmond has its own Industrial Safety Ordinance covering facilities within city limits. Under this framework, mechanical integrity programs, damage mechanism reviews and inspection data quality receive intense scrutiny. An inspector’s call on a thickness reading, a tube wall loss indication or a material verification can end up in a regulator’s review.

That scrutiny meets a workforce challenge. Much refinery NDT is concentrated in turnarounds, when dozens of technicians arrive for a few weeks of intense work on exchangers, columns, drums, piping and tanks. Between turnarounds, many of those technicians work other jobs or other methods. Perishable skills like IRIS tube data interpretation, recognizing localized corrosion in a thickness grid, or reading guided-wave screening results fade quickly. And the conversion of units to renewable feedstocks has introduced different process conditions, including different corrosion and hydrogen-related concerns and new or replaced equipment with different materials, so even experienced inspectors are seeing situations they did not see ten years ago.

Practice on real equipment is hard to get. Flawed tube bundles and corroded pipe specimens are expensive and bulky, reference standards are tied up in daily work, and radiography practice requires licensed sources or registered X-ray equipment regulated by the California Department of Public Health Radiologic Health Branch, plus restricted areas and trained staff. California also requires a state-recognized radiographer card for industrial radiographers. A simulator addresses the practice part: you can repeat the same tube-inspection or corrosion scenario as often as you want, safely and without consuming anything.

Methods You Can Practice: IRIS, PMI, LRUT and Tank Scenarios for Refinery Work

Practical NDT covers 12 methods. Surface: penetrant testing (PT), magnetic particle testing (MT) and visual testing (VT). Volumetric: contact ultrasonic testing (UT), phased array ultrasonic testing (PAUT), time-of-flight diffraction (TOFD) and radiographic testing (RT). Electromagnetic: eddy current testing (ET) and magnetic flux leakage (MFL). Specialist: long-range guided-wave ultrasonic screening (LRUT), internal rotary inspection system (IRIS) ultrasonic testing for heat-exchanger and boiler tubes, and positive material identification (PMI).

For refinery corridor work, the specialist methods are especially valuable. IRIS jobs let you work through heat-exchanger tube inspection, reading rotary ultrasonic data for wall loss, pitting and wear, which is a turnaround staple. PMI jobs train you to verify alloys on piping components and fittings, a mechanical-integrity basic that matters even more when units are rebuilt or converted and materials change. LRUT jobs cover guided-wave screening along pipe runs, where you learn to distinguish welds, supports and bends from zones that need follow-up inspection. The ultrasonic testing simulator jobs cover thickness surveys, corrosion interpretation and angle-beam weld inspection.

Phased array jobs cover corrosion mapping logic and weld inspection, and TOFD jobs cover diffracted tip signals for flaw detection and sizing in welds. In the Storage Tank environment, you work UT shell thickness surveys and MFL floor screening on a full-size tank, mirroring the tank farms along the corridor. Eddy current and surface-method jobs cover crack detection on welds and components, and RT interpretation jobs let you evaluate virtual weld radiographs for porosity, slag, lack of fusion, incomplete penetration and cracks, with no radiation involved. Every job is scored with immediate feedback on what you found, missed or mis-sized.

Built for Every Skill Level

There are three kinds of users. New trainees get guided fundamentals: 33 guided lessons explaining what each method is doing and what a correct result looks like, followed by beginner jobs that get harder as you succeed. In the East Bay, that trainee might be coming from a local community college process technology or welding program, moving from operations or maintenance into inspection, or starting as a helper at an inspection company that works the corridor.

Working technicians get rare-defect refreshers between assignments. Adaptive scenarios raise the difficulty when you are consistently right and ease off when you are not. That makes the platform a natural warm-up in the weeks before a turnaround, or when a technician is asked to pick up IRIS or PMI after months of thickness work.

Level III and team leads can build and assign scenario sets, benchmark crews objectively and find coverage gaps. Before a turnaround, a lead can check whether incoming technicians are consistent on tube inspection, corrosion interpretation or alloy verification, rather than finding out halfway through the job. The scenario library was designed by Anoop Rayavarapu, ASNT NDT Level III and founder of Atlantis NDT, who also leads Atlantis training, so the scenarios reflect the calls a Level III has to stand behind in a heavily regulated plant.

How It Complements Formal ASNT Training and NDT Practical Exam Preparation

Stated plainly: Practical NDT is a practice and readiness tool, not a certification. It does not grant any level, and it does not replace the practical examination on real specimens required by ASNT SNT-TC-1A and your employer’s written practice. Under SNT-TC-1A, the written practice defines training hours, experience hours and the general, specific and practical exams for each method and level, and the practical exam uses real equipment on real specimens. It also does not replace any site-specific qualification a refinery or its contractors require, or California’s radiographer card requirements.

What it does is help you arrive prepared. Candidates who struggle in practicals often know the theory but have not seen enough varied indications to recognize and document them quickly under pressure. Practical NDT gives you that repetition and builds procedural discipline, since each job expects the right steps in the right order and scores you on them.

For formal training and certification preparation, see the Atlantis NDT training programs. Structured training and supervised experience are your qualification path; Practical NDT is the extra repetitions in between.

The Contra Costa Refinery Corridor: Regulation, Renewable Conversions and the Workforce

Described as industry context only, the corridor’s NDT demand has deep roots. Refining in Richmond and Martinez dates back more than a century, and the area has long been one of the West Coast’s key fuel-producing regions, supplying Northern California with gasoline, diesel and jet fuel. Crude refining continues at large sites in Richmond and Martinez, along with chemical plants, marine terminals, pipelines and tank farms along San Pablo Bay and the Carquinez Strait.

The corridor is also changing fast. In 2023 a Martinez refinery was converted to a renewable fuels facility, and in 2024 the refinery at Rodeo was converted to renewable fuels production. Across the strait, the Benicia refinery, which produced around 170,000 barrels per day of fuels, stopped refining in April 2026. These shifts bring new inspection work: converted units with new equipment and different process conditions, decommissioning and mothballing inspections, and continued mechanical integrity work at the remaining crude refineries. For inspectors, that means a wider range of materials and damage mechanisms to recognize.

Regulation is a defining feature. Cal/OSHA’s refinery process safety management standard, Title 8 Section 5189.1, governs refinery processes statewide. Contra Costa Health administers the county’s Industrial Safety Ordinance, and the City of Richmond has its own. The Bay Area Air Quality Management District regulates emissions, and the California Department of Public Health Radiologic Health Branch regulates industrial radiography and administers radiographer certification. These frameworks put a premium on accurate, well-documented inspection, and on technicians who can make reliable calls consistently.

Matching Corridor Work to the Five Practical NDT Environments

Practical NDT’s five workplace environments map onto the corridor clearly. The Oil & Gas Site, with 73 jobs, is the core environment: weld, corrosion, tube and screening practice in a process plant, including IRIS, PMI and LRUT. The Storage Tank environment covers UT shell thickness surveys and MFL floor screening on a full-size tank, matching the corridor’s tank farms and marine terminals. The Welding Workshop, with 52 jobs, covers weld coupons and fabrication joints for VT, MT, PT, RT interpretation, phased array and TOFD, relevant to turnaround repairs and unit conversions. The NDT Lab, with 52 jobs, offers bench specimens and reference blocks for calibration discipline. The Aircraft Hangar, with 54 jobs, is available for technicians who also support Bay Area aviation maintenance. A Level III can build turnaround-readiness sets combining the Oil & Gas Site and Storage Tank environments.

Bringing Practical NDT to Your Richmond or Martinez Team

Start with a walkthrough. Request a Practical NDT demo for the Bay Area and we will show you the environments, methods and Level III tools using the kinds of jobs your team handles, such as exchanger tube inspection, alloy verification, piping corrosion and tank inspection. It runs in a browser or app, so there is nothing to install on a plant network.

Rollouts usually start with a small group before a turnaround: some trainees, a few experienced technicians and the Level III who builds scenario sets. The lead reviews scoring, identifies gaps and adjusts assignments, then extends the program across the crew. Pricing is quote on request, depending on team size and use; ask for a quote. Atlantis built the first-ever online practical NDT simulation portal for practice and hands-on experience, and we would like East Bay refinery inspectors to try it.

Frequently Asked Questions

Does Practical NDT replace the practical certification exam?

No. It is a practice and readiness tool. Under ASNT SNT-TC-1A, certification follows your employer’s written practice, which requires training, experience and a practical examination on real specimens. It also does not replace site qualifications or California’s radiographer card requirements. It helps you prepare and stay sharp.

What experience level is it for?

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

Can it help crews prepare for a refinery turnaround?

Yes, as practice. A Level III can assign IRIS, PMI, thickness, LRUT and tank jobs in the weeks before a turnaround and use the scoring to see who is ready and where coverage is thin. Actual turnaround work follows the plant’s procedures and inspection plans.

Does it reflect the renewable fuels conversions on the corridor?

The scenarios focus on core inspection skills, such as corrosion interpretation, tube inspection, alloy verification and weld inspection, that apply to both crude and converted units. It does not model any specific plant; your site’s damage mechanism reviews and procedures still govern real inspections.
