This page covers Corpus Christi specifically

What follows relates to inspection and consulting work in and around Corpus Christi. If you are looking for the service itself rather than local coverage — outsourced ASNT Level III, written practice authoring, procedure approval and audit support, delivered wherever you operate — that is set out in full on the outsourced ASNT Level III page, which is the right starting point for a national or multi-site enquiry.

What an outsourced ASNT Level III actually does

Most inspection companies do not need a full-time Level III; they need the functions a Level III performs. Those are specific and separable: authoring and signing the written practice, developing and qualifying procedures for each method offered, examining and certifying Level I and Level II personnel, validating techniques and equipment, and being available and named when a client audits the programme. Engaged as a retained service, that covers the technical accountability without carrying the salary.

The Corpus Christi asset base and what it demands

Corpus Christi is the largest US crude oil export terminal, with Cheniere's Corpus Christi LNG complex (Trains 1-3 plus the Stage 3 expansion) loading more than 15 mtpa of LNG, and Citgo's Corpus Christi Refinery, Flint Hills Resources West Refinery, and Valero's Bill Greehey complex collectively processing over 850,000 bpd. The Port of Corpus Christi has invested billions in deepening the channel to accommodate VLCCs, driving inspection demand on jetty structures, loading arms, and a dense cluster of new export-grade storage tanks. Hurricane exposure on the Texas Gulf Coast and the high cyclic loading of LNG loading operations on cryogenic equipment create a strong case for digital twin asset-integrity programmes.

Service lines

• Written practice authoring and revision to ASNT SNT-TC-1A, ANSI/ASNT CP-189, NAS 410 or ISO 9712, including the annual review most quality systems require and few actually perform
• Procedure development and approval across UT, PAUT, TOFD, RT, MT, PT, ET and VT, written against the governing construction or in-service code and qualified on representative specimens
• Personnel qualification and certification — general, specific and practical examinations, vision examination administration, and the experience-hour records that support them
• Risk-based inspection programme design under API 580 and API 581, built on measured corrosion rates rather than default rates
• Fitness-for-service assessment under API 579-1/ASME FFS-1 — Part 4 general metal loss, Part 5 local metal loss, Part 9 crack-like flaws
• ISO 17020 and ISO 17025 accreditation support, internal audit and pre-assessment against the standard the assessor will actually apply
• Failure investigation, root-cause analysis and expert-witness support where a finding becomes contentious

Codes and client regimes covered

ASME Section V, Section VIII and Section IX; ASME B31.1 and B31.3; AWS D1.1 and D1.5; API 510, API 570, API 653, API 577, API 578 and API 1104; ISO 17635, ISO 17636 and ISO 17640; NACE/AMPP MR0175 and MR0103 for sour service. Operator-specific approvals — Aramco, ADNOC, QatarEnergy, KOC, PETRONAS, Shell and similar — are prepared against the client's own vendor-qualification checklist rather than a generic template.

How engagements are structured

Most procedure reviews and written-practice updates are returned signed and stamped within two to five business days. Larger scopes — building a multi-method programme from nothing, preparing an ISO 17020 accreditation package, or standing up an RBI programme — are scoped individually with a defined deliverable list. Work runs per-project or on retainer, and a retainer is usually the better arrangement once a company is being audited by more than one client.

What tends to be found first

• A written practice that has not been reviewed since it was adopted, and no longer matches how the crews work
• Technique sheets circulating in several uncontrolled versions beneath a controlled procedure
• Certification records complete for the certificate but missing vision examinations or documented on-the-job hours
• Calibration certificates held for instruments but not for probes, wedges and reference blocks — the most common ISO 17025 finding
• No way to reconstruct which procedure revision applied to an inspection performed two years ago

This page covers Corpus Christi — not the national service

Atlantis supports inspection programmes in Corpus Christi, Texas across the refining cluster, the export terminals that grew with crude and LNG shipments, and the wind and marine work along the coastal bend. Work here answers to API in-service codes across the refining and terminal estate, with marine scopes answering to classification societies. Teams mobilise to your site under Atlantis procedures — we do not claim an office or laboratory in Corpus Christi, and say so plainly.

If you are looking for ASNT Level III consulting as a national engagement rather than support in this specific market — a named Level III of record, procedure approval and written practice ownership, technique qualification and audit defence, delivered wherever your sites are — that is the page to read. This one stays scoped to Corpus Christi.

Three refineries line the Corpus Christi Ship Channel: Flint Hills Resources Corpus Christi West at roughly 300,000 b/d, CITGO at about 157,000 b/d, and Valero's East and West plants at a combined 370,000 b/d, East on light sweet crude and West on heavier grades. Inspection work here is audited against OSHA PSM (29 CFR 1910.

Cheniere's three-train LNG terminal sits on the La Quinta Channel, with the ExxonMobil-SABIC Gulf Coast Growth Ventures cracker at Gregory and Chemours' refrigerant plant nearby. Enbridge Ingleside Energy Center, the largest US crude export terminal, loaded 415 million barrels in 2025. Corpus Christi Army Depot is the world's largest helicopter overhaul facility, and Kiewit Offshore Services' 550-acre Ingleside yard builds offshore jackets and topsides. Inspection demand is driven by operators including Flint Hills Resources Corpus Christi West Refinery, CITGO Corpus Christi Refinery, Valero Corpus Christi East and West Refineries, Cheniere Corpus Christi LNG (La Quinta Ship Channel), whose contracts set the qualification bar their supply chain has to meet. An outsourced ASNT Level III covers the signing authority a firm needs without carrying the role on staff — written practice, procedure approval, examination oversight and audit attendance.

Which codes govern NDT inspection work in Corpus Christi?

OSHA PSM (29 CFR 1910.119), API 510 / 570 / 653, 49 CFR 193 and NFPA 59A (LNG facilities), NAS 410 and FAA 14 CFR Part 145 (depot and aviation MRO), USCG 33 CFR 154 (marine transfer operations), ASNT SNT-TC-1A are the regimes named in contracts here. Each puts the obligation on the employer: a written practice, a Level III who signs it, and records that survive an audit. Which one binds a given job is set by the client contract and the construction code, not by preference.

Can an outside Level III sign our written practice in Corpus Christi?

Yes. SNT-TC-1A places the obligation on the employer, and the employer may designate a contracted Level III to write and sign the written practice, approve procedures and administer examinations. The Level III must be qualified in each method they sign for. What an outside Level III cannot do is substitute for the employer's own records.

Which employers in Corpus Christi drive inspection qualification requirements?

Flint Hills Resources Corpus Christi West Refinery, CITGO Corpus Christi Refinery, Valero Corpus Christi East and West Refineries, Cheniere Corpus Christi LNG (La Quinta Ship Channel) and their contractors. Approved-supplier requirements flow down: a firm bidding into that supply chain inherits the qualification bar whether or not its own client names it directly, which is why audit-readiness is a bidding issue rather than a paperwork one.

How quickly can a firm in Corpus Christi get audit-ready?

The written practice and procedure set can be drafted and signed inside weeks. What cannot be compressed is documented experience: on-the-job hours accumulate in real time, and reconstructing undocumented hours needs employer attestation. Firms that start when the audit is scheduled rather than when it is announced clear it without findings.

Does Atlantis deliver training as well as Level III cover in Corpus Christi?

Yes — training is delivered on-site at the employer's facility, at an arranged venue, or blended with online theory and an in-person practical, under the same Level III oversight. Employers building a cohort rather than certifying one technician usually pair the two so the written practice and the training programme match.
