NDT Inspection Services in Alaska

Short answer: Atlantis NDT provides non-destructive testing inspection in Alaska: ultrasonic thickness surveys and corrosion mapping, phased array (PAUT) and TOFD weld inspection, radiography through radiography crews licensed for work in Alaska, magnetic particle, penetrant, visual and eddy current testing, plus the NDE that API 510 pressure vessel, API 570 piping and API 653 storage tank programmes rely on. Work is performed by ASNT-certified technicians under ASNT NDT Level III oversight, crews are mobilised to your site, from Anchorage and the Kenai Peninsula to Fairbanks, Valdez and the North Slope, and results arrive as a code-referenced digital report.

Inspection in Alaska is shaped by three things that do not apply in the lower 48 in the same way: distance, cold and a regulatory map that leans heavily on federal agencies. A crew bound for Prudhoe Bay flies through Deadhorse and works a rotation; a crew at a Cook Inlet platform depends on weather and marine logistics; a tank inspection at Valdez sits under some of the most closely watched oil-spill rules in the country. Alaska is also not an NRC Agreement State, and it has no state pipeline safety programme, so PHMSA and the NRC deal with operators directly. This page maps where inspection work is, what methods and codes apply, which agencies shape scope, and what Atlantis does and does not deliver. When you are ready, request an Alaska inspection quote with the asset, method, code, location and season.

Where inspection work is in Alaska

Direct answer: Alaska inspection demand concentrates on the North Slope oil fields around Prudhoe Bay, Kuparuk and Alpine, along the Trans-Alaska Pipeline System to the Valdez Marine Terminal, in Cook Inlet and on the Kenai Peninsula at Nikiski, in the Fairbanks and North Pole area, and in Anchorage with its port, airport and military bases. Mining, power and marine work add scopes across the state.

North Slope: Prudhoe Bay, Kuparuk, Alpine and new developments

The North Slope is the centre of Alaskan oil production. Prudhoe Bay, Kuparuk and the Alpine fields carry thousands of miles of well lines, flow lines and transit lines, plus gathering centres, flow stations, compressor plants, seawater treatment and power generation, and new developments such as Willow and Pikka are adding modules, piping and facilities. Inspection work is dominated by corrosion: produced water, CO2 and solids drive internal corrosion, and elevated, insulated lines are exposed to corrosion under insulation where moisture gets behind jacketing. After the 2006 Prudhoe Bay transit-line leaks, internal corrosion monitoring and inspection of low-flow lines received intense attention across the industry. The everyday scopes are UT thickness and corrosion mapping on piping and vessels, profile radiography and UT at CUI-prone locations where insulation can be opened, weld inspection on module tie-ins and repairs, and tank inspection at pads and plants. See practical NDT for North Slope work.

Trans-Alaska Pipeline System and Valdez

The Trans-Alaska Pipeline System runs roughly 800 miles from Prudhoe Bay to the Valdez Marine Terminal, operated by Alyeska Pipeline Service Company, with pump stations along the route and the terminal's crude storage tanks and berths at the head of Prince William Sound. Pipeline integrity there is driven by the operator's programme, in-line inspection and federal regulation; contractors supply NDE for repairs, station piping, tanks and terminal equipment. Valdez also hosts refining and fuel distribution. Tank floor scanning, shell thickness surveys, weld inspection on station and terminal piping, and structural inspection on marine and dock steel are typical. See our pipeline inspection services.

Cook Inlet, Kenai and Nikiski

Cook Inlet has produced oil and gas since the 1950s and 60s. Offshore platforms, subsea and onshore pipelines, gas fields that supply Southcentral Alaska, the Marathon Kenai refinery at Nikiski and associated terminals and gas facilities make the Kenai Peninsula a dense inspection market for its size. Older assets mean thickness surveys, corrosion mapping and repair-weld inspection on piping and vessels, API 653 work on refinery and terminal tanks, and structural inspection on platforms and docks in a strong-current, icy marine environment. See the refining Level III consulting page for Anchorage and Southcentral and practical NDT for refinery work.

Anchorage and the Mat-Su

Anchorage is the logistics hub of the state: the Port of Alaska, Ted Stevens Anchorage International Airport with its large air-cargo operation, Joint Base Elmendorf-Richardson, utility power plants and fuel terminals. Industrial inspection here covers fuel tanks and transfer piping, power-plant pressure equipment, structural steel and cranes, and fabrication shops that build modules and skids for the North Slope. Aviation maintenance NDT follows FAA and manufacturer requirements and is normally done by certificated repair stations, so we focus on the industrial side. See third-party inspection in Anchorage.

Fairbanks, North Pole and the Interior

The Interior combines fuel refining and terminals at North Pole, power plants in Fairbanks and Healy, Eielson Air Force Base and Fort Wainwright, and large hard-rock mines such as Fort Knox and Pogo. Winter temperatures far below zero shape everything: equipment, couplants, PT materials and personnel all have limits. Scopes include tank inspection, boiler and pressure vessel NDE, mill and crusher structural welds, and piping thickness surveys.

Southeast and Western Alaska

Southeast Alaska has a shipyard at Ketchikan, mines such as Greens Creek and Kensington, seafood processing and hydro power, while Western and Northwest Alaska include the Red Dog mine and its port, and fuel tank farms in hub communities. These scopes are planned around barge and air logistics and short seasons, and usually bundle several assets into one mobilisation.

NDT methods we deliver in Alaska

Direct answer: Atlantis delivers UT thickness and corrosion mapping, PAUT, TOFD, conventional shear-wave UT, radiography through crews licensed for Alaska work, MT, PT, VT, eddy current and MFL tank floor scanning. Cold-weather limits on couplants, penetrants and equipment are addressed in the procedure. Final method selection is agreed with your inspector of record during scoping.

Cold changes the physics. Ultrasonic velocity varies with temperature, so thickness readings on cold steel need calibration on a block at a similar temperature; couplants must be chosen so they do not freeze; batteries and screens lose performance; and liquid penetrant examination outside the standard temperature range in ASME Section V requires a procedure qualified for the actual temperature. Every Atlantis procedure is reviewed by an ASNT NDT Level III with these limits in mind, and every technician is certified under an SNT-TC-1A written practice. Where your site requires its own procedures, we work to those.

API 510, 570 and 653 inspection support in Alaska

Direct answer: Atlantis performs the NDE that API 510 pressure vessel, API 570 piping and API 653 storage tank inspections rely on, including thickness surveys, weld examination, tank floor scanning and visual examination, and hands documented results to your API-certified Authorized Inspector, who remains the inspector of record and signs the inspection report.

API 510 pressure vessels. Separators, scrubbers, slug catchers, heaters, refinery drums and exchangers across the North Slope, Cook Inlet and the Interior run on API 510 programmes. We carry out external visual examination, UT thickness at the vessel's CMLs, corrosion mapping where localised loss is expected, PAUT or TOFD on welds with a cracking history or prior repairs, and MT or PT on nozzles and attachments during entries. Readings are reported against the previous survey so your inspector can calculate corrosion rates and set intervals. See API 510 pressure vessel inspection support.

API 570 piping. On the North Slope the piping population is enormous and largely insulated, so CML surveys, injection-point and deadleg scanning, and CUI screening where insulation is opened are the core of most programmes. At refineries and terminals the same work runs on process and transfer piping. Results are delivered per CML so they load into your inspection data system. See API 570 piping inspection support.

API 653 storage tanks. Alaska's tanks range from the crude tanks at Valdez to refinery tanks at Nikiski and North Pole, fuel terminals in Anchorage and tank farms in remote hub communities. For out-of-service inspections we perform MFL floor scanning with UT follow-up, shell course thickness surveys, shell-to-bottom and repair weld examination and nozzle work; for external inspections we survey shell thickness, examine roof, shell, foundation and appurtenances, and take settlement measurements presented against API 653 Annex B, which matters on permafrost and frost-susceptible foundations. See API 653 tank inspection support.

What we do not do: Atlantis does not sell risk-based inspection (API 580/581) or fitness-for-service (API 579) assessments, and it does not act as the Authorized Inspector. Our reports give your engineers clean, traceable data; the integrity decisions built on it stay with your programme.

Turnarounds, shutdowns and planned inspection

Direct answer: In Alaska, inspection timing is set by season and logistics as much as by turnaround schedules. Atlantis joins the planning stage, agrees methods and procedures, completes site prequalification and mobilises crews on dates fixed during scoping, often bundling several assets into one trip to make the most of each mobilisation.

Summer is the main window for tank out-of-service inspections, tank-farm work in remote communities, construction-season weld inspection and marine and dock work, because barges and roads are open and temperatures allow normal procedures. Winter brings ice roads and pads on the North Slope, which opens access to some locations but pushes NDE into heated enclosures and procedures qualified for low temperatures. Plant turnarounds at refineries and gas facilities follow their own calendar, and North Slope facility outages are planned well ahead.

A good scope still has three layers: on-stream work before the outage (thickness surveys, external visual, in-service weld examination), work that needs entry or isolation during the outage, and re-examination of repair welds before start-up. In Alaska we add a fourth: logistics. Crew travel through Anchorage, Fairbanks or Deadhorse, camp space, North Slope orientation such as the North Slope Training Cooperative programme required by many operators, equipment freight and weather contingency all have to be planned before the dates are fixed. Tell us early and we will build the plan around your season. Plan an Alaska inspection campaign.

Alaska regulations that shape inspection

Direct answer: In Alaska, boilers and unfired pressure vessels are regulated by the Department of Labor and Workforce Development Mechanical Inspection Section; radioactive materials, including radiography sources, are licensed by the NRC because Alaska is not an Agreement State; PHMSA directly regulates both interstate and intrastate pipelines; AKOSH enforces process safety; and ADEC regulates oil discharge prevention.

Boilers and pressure vessels: Mechanical Inspection Section

The Mechanical Inspection Section of the Division of Labor Standards and Safety administers Alaska's boiler and pressure vessel programme under AS 18.60, covering both new construction and existing installations. A state certificate of operation is required for boilers and unfired pressure vessels, with exemptions set out in the regulations, and inspections may be made by state deputy inspectors or approved inspectors. NDE data from Atlantis supports those inspections and the owner's API 510 programme; it does not replace the commissioned inspector. Confirm the status of a specific vessel with the Mechanical Inspection Section.

Radiography: NRC licensing because Alaska is not an Agreement State

Alaska has not signed an agreement with the NRC, so licences for radioactive materials such as industrial radiography sources are issued and inspected by the NRC, through its Region IV office, rather than by the state. The state keeps jurisdiction over X-ray equipment and certain other sources. Atlantis does not claim to hold an NRC or Alaska radiography licence: radiography on Atlantis scopes is performed by radiography crews licensed for work in Alaska, working to reviewed procedures under our Level III. Where radiation exclusion zones are hard to manage on a crowded pad or in a module, PAUT or TOFD may be an alternative if your code and owner accept it.

Pipelines: PHMSA directly, plus state right-of-way oversight

Alaska is one of very few states that has not filed a state certification with PHMSA for gas or hazardous liquid pipelines, so PHMSA's Office of Pipeline Safety inspects and enforces the federal regulations (49 CFR Parts 192 and 195) for both interstate and intrastate operators in Alaska, with staff based in Anchorage. Separately, the state oversees pipeline right-of-way leases on state land, including the Trans-Alaska Pipeline System, through the Department of Natural Resources. Girth-weld inspection on new construction normally follows API 1104.

Process safety, tanks and oil discharge prevention

Alaska runs an OSHA-approved State Plan, Alaska Occupational Safety and Health (AKOSH), which enforces process safety management requirements equivalent to 29 CFR 1910.119: written inspection and testing procedures, inspection following recognised and generally accepted good engineering practice, and documentation of each inspection. For oil storage and facility piping, the Alaska Department of Environmental Conservation administers oil discharge prevention and contingency plan rules under 18 AAC 75, which include tank and facility-piping integrity requirements, and EPA's SPCC rule (40 CFR Part 112) expects tank integrity testing to an industry standard such as API 653 or STI SP001. The result is that Alaskan operators need well-documented tank and piping inspection records.

Inspection reports clients can use

Direct answer: Every Atlantis inspection in Alaska produces a digital report built in our own reporting platform: each reading, indication and photo tied to the asset, location, procedure, technician certification and instrument calibration, with acceptance criteria quoted from the governing code. Reports are reviewed under ASNT Level III oversight before release.

Remote work makes good field data capture essential. Our reporting tools capture data offline, which matters on a pad, a platform or a remote tank farm with no reliable connection, and sync when a connection is available. Inspectors of record, ADEC, PHMSA and insurers reject reports for predictable reasons: readings that cannot be traced to a CML, indications without a procedure and acceptance criterion, technicians whose certification cannot be shown, and instruments without calibration records, including the calibration temperature for cold-weather UT. The platform is designed around those points and exports in formats your inspection data management system can import. Read more on our NDT inspection software page, or compare options in best NDT reporting software 2026.

The data can also go further than a PDF. Results can feed scheduling, certification tracking and invoicing in Atlantis ERP (see NDT ERP in Alaska), or be placed on a 3D model of a pad, module or tank farm in our digital twin platform (see digital twins in Alaska), which is especially useful when engineers in Anchorage or outside the state need to review findings on assets they cannot easily visit.

Frequently asked questions about NDT inspection in Alaska

Which NDT inspection services does Atlantis offer in Alaska?

UT thickness and corrosion mapping, PAUT, TOFD, conventional UT, radiography through crews licensed for Alaska work, MT, PT, VT, ET and MFL tank floor scanning, plus NDE support for API 510, API 570 and API 653 programmes and pipeline inspection, under ASNT Level III oversight.

Do you have an office in Anchorage?

No. Atlantis does not operate a physical office or lab in Alaska. Crews are mobilised to your site, and travel, freight and schedule are agreed during scoping.

Can you work on the North Slope?

Yes, by arrangement with the operator. North Slope work requires operator prequalification, site orientation, camp space and travel through Deadhorse, all planned during scoping before dates are fixed.

Is Alaska an NRC Agreement State for radiography?

No. Alaska is not an Agreement State, so the NRC licenses radioactive materials, including industrial radiography sources, through Region IV. Radiography on our scopes is done by crews licensed for work in Alaska.

Who regulates pipelines in Alaska?

PHMSA. Alaska has not filed a state pipeline safety certification, so PHMSA's Office of Pipeline Safety regulates both interstate and intrastate pipelines in the state. The Department of Natural Resources oversees right-of-way leases on state land.

Does Alaska inspect boilers and pressure vessels?

Yes. The Department of Labor and Workforce Development Mechanical Inspection Section regulates boilers and unfired pressure vessels and issues certificates of operation, with inspections by state or approved inspectors.

Can you perform API 653 tank inspections in Alaska?

We perform the NDE an API 653 inspection relies on: MFL floor scanning with UT follow-up, shell thickness, weld examination and settlement measurement. Your API 653-certified Authorized Inspector remains the inspector of record and signs the report.

Can NDT be done in sub-zero temperatures?

Yes, within limits. UT needs couplants that do not freeze and calibration at a similar temperature, PT outside the standard range needs a qualified procedure, and much winter work is done in heated enclosures. Our Level III reviews these limits in the procedure.

How much does NDT inspection cost in Alaska?

Atlantis quotes on request. Cost depends on method, number of locations or welds, access, travel, freight and camp logistics, season, crew size and the report format required. Send the scope and you will get a written quote.

When is the best time to schedule tank inspections?

Most out-of-service tank work and remote tank-farm inspection is scheduled in summer, when barges and roads are open and temperatures allow standard procedures. Book early, because the season is short.

Will our inspector or regulator accept your reports?

Reports quote the procedure, acceptance criteria and code, list technician certifications and instrument calibration, and are reviewed under ASNT Level III oversight. Agree the report format with us during scoping.

Do you offer RBI or fitness-for-service assessments?

No. Atlantis does not sell API 580/581 risk-based inspection or API 579 fitness-for-service assessments. We provide the inspection data those programmes use.
