Storage Tank Inspection in Three Rivers, TX

Storage Tank Integrity Across South Texas

Aboveground storage tanks support refining, production, terminals, and other process operations throughout the Eagle Ford and Coastal Bend. For facilities around Three Rivers, a tank’s condition can affect containment, throughput, regulatory obligations, and safe operations. Corrosion, floor metal loss, shell thinning, settlement, or roof deterioration may develop over time and can remain difficult to identify through routine visual checks alone.

A planned inspection program gives plant managers and integrity engineers better evidence for maintenance and operating decisions. TechCorr’s Three Rivers team serves South Texas pipeline and refining clients with field inspection capabilities that include pipeline NDE, radiographic testing callouts, and conventional NDE. That regional experience helps us coordinate tank assessment alongside broader asset integrity needs, with inspection scope shaped around the asset, its service history, operating constraints, and applicable requirements.

Storage Tank Inspection as NDT and NDE

Storage Tank Inspection is a structured application of non-destructive testing and inspection methods to evaluate a tank without damaging the asset. The approach can include visual examination, ultrasonic (UT) thickness measurement, corrosion mapping, magnetic flux leakage (MFL) floor scanning, and engineering evaluation. Each method provides different evidence: visual inspection documents observable conditions, UT measures remaining thickness, and MFL identifies floor areas that may warrant targeted follow-up.

NDT results are not a substitute for engineering judgment. Findings must be interpreted in context, then confirmed or quantified where appropriate. For example, UT prove-up can assess MFL floor indications and help determine their volumetric significance. Depending on the inspection objective and tank status, assessments may be performed while a tank is in service or during an out-of-service inspection. Acoustic Emission (AE) and TANKPAC™ testing may also support condition assessment without taking a tank out of service when suitable for the application.

The right combination of NDE techniques depends on access, tank configuration, service conditions, prior inspection data, and the questions the owner needs answered. A defined scope helps avoid treating a single test result as a complete condition assessment and supports clear, defensible recommendations.

What TechCorr’s Three Rivers Team Delivers

TechCorr provides in-service and out-of-service visual inspection, UT thickness readings, and UT corrosion surveys of tank shells and roofs. For floors, our capabilities include MFL testing and UT prove-up of relevant indications. Inspection scope can also include API 653 calculations, shell and edge settlement assessment, and verticality measurements, as appropriate to the tank and project requirements.

Before fieldwork, the team can coordinate the inspection plan, access needs, operating constraints, and required records with the facility. During execution, inspectors collect and document condition data using the methods selected for the scope. The aim is to give the owner useful information for repair planning, continued-service decisions, and longer-term asset integrity management—not simply a list of readings.

Deliverables are compiled in a comprehensive electronic report. Depending on the scope, the report can include findings and recommendations, relevant calculations, API checklist items, CAD drawings, and photographs. Clear documentation helps integrity teams compare conditions over time, prioritize follow-up, and retain a usable inspection record for maintenance and compliance workflows.

Standards, Qualifications, and Inspection Planning

Storage tank work should be planned against the standards and regulatory obligations applicable to the asset and inspection activity. API 653 is a central reference for aboveground storage tank inspection, repair, alteration, and reconstruction. API 510 and API 570 address pressure vessel and piping inspection programs; they may be relevant to a broader facility integrity plan, but they are not interchangeable with API 653 tank requirements. The owner and responsible engineering personnel should confirm which codes, editions, jurisdictional rules, and inspection intervals apply.

Personnel qualifications and written procedures also matter. ASNT qualification frameworks are relevant to NDT personnel and method-specific work, while project requirements and employer programs govern how qualifications are established and documented. NACE, now part of AMPP, provides corrosion-related standards and guidance that may inform coatings and corrosion-control considerations. ISO standards can support quality management and consistent work processes, depending on the service and contract scope. TechCorr aligns inspection planning and reporting with applicable requirements and the agreed scope; specific qualifications and code responsibilities should be confirmed for each project.

Why TechCorr Three Rivers

TechCorr brings advanced tank inspection capabilities together with a Three Rivers field presence serving South Texas pipeline and refining operations. Our local strengths in pipeline NDE, radiographic testing callouts, and conventional NDE support coordinated field response across the Eagle Ford and Coastal Bend. For tank owners, that means access to a technically broad team able to plan inspection around operational needs and provide documented findings for integrity decisions.

Whether you are planning an out-of-service inspection, evaluating an in-service tank, or developing a recurring assessment program, TechCorr can help define a practical scope and select appropriate NDT methods. Contact the Three Rivers team to discuss tank type, service history, available records, access, operating status, and inspection objectives. We’ll work with your team to plan Storage Tank Inspection that supports safe operations, informed maintenance, and long-term asset integrity.
