Built by a working API 653 inspector
API 653 Inspection Software Built for the Field.
Capture field inspection data once, carry it through API 653 calculations, diagrams, findings, and review, then deliver professional reports and interactive client access from the same inspection record.
The problem
One inspection shouldn’t require six disconnected tools.
Field data should not have to be re-entered, reconciled, and reformatted every time it moves from inspection to engineering review and final delivery.
- 01Field notes
- 02Spreadsheets
- 03Calculators
- 04CAD files
- 05Photo folders
- 06Report templates
FieldSight inspection record
One source from field entry to client delivery.
- Linked inspection data and calculations
- Photos, findings, and review in context
- Versioned professional deliverables
01Capture
Record the inspection once.
Open one tank record and move through a structured inspection workflow without separating measurements, observations, photos, and findings into different files.
- Structured shell, bottom, roof, and appurtenance records
- UT and field measurements tied to the inspection
- Photos and findings captured in context
- Saved and synchronized inspection records
02Calculate
Keep the engineering beside the data.
Carry field measurements directly into API 653 evaluation workflows so the source readings, governing calculations, results, and review basis stay connected.
- API 653 Annex B settlement evaluation
- Corrosion rates, remaining life, and inspection intervals
- Shell, bottom, roof, and appurtenance calculation paths
- Reviewable inputs, results, notes, and supporting evidence
03Document
Turn field measurements into a visual inspection record.
Build tank layouts, locate indications by X/Y coordinates, document repairs, and keep every visual tied to the same inspection data.
- Bottom, shell, fixed-roof and floating-roof diagrams
- X/Y indication and weld-defect records
- Automatic plate-level views and repair geometry
- CAD/DXF drawing export
04Generate
Generate the deliverable without rebuilding the inspection.
Carry the inspection record into a client-ready deliverable without reassembling the calculations, drawings, findings, photographs, and document structure by hand.
- Professional PDF and editable Word output
- Company branding and report formatting
- Calculations, diagrams, findings and photos carried forward
- Finalization and controlled report versions
05Share
Deliver the report without another handoff.
Finalize the inspection and provide clients a controlled interactive report they can review from a browser, while retaining professional PDF and Word deliverables when traditional files are required. Contact FieldSight for a guided walkthrough of the complete workflow and a finalized demo report.
- Interactive browser-based client reports
- No account or software required for report recipients
- Professional PDF and Word deliverables remain available
- Controlled finalized report sharing

What inspection teams ask before they start.
Clear answers about professional judgment, report delivery, calculations, and the difference between FieldSight plans.
What is FieldSight?
FieldSight is API 653 tank inspection and reporting software that connects field data, engineering calculations, diagrams, findings, photographs, report generation, and client delivery in one inspection record.
Who is FieldSight built for?
FieldSight is built for API 653 inspectors, field technicians, technical reviewers, inspection managers, and inspection companies performing aboveground storage tank inspection work.
Does FieldSight replace the API 653 inspector or engineering judgment?
No. FieldSight organizes inspection data and assists with calculations, evaluations, and documentation. The qualified inspector remains responsible for reviewing the inspection data, applying the governing requirements, exercising professional judgment, and approving the final report.
Can FieldSight generate PDF and Word inspection reports?
Yes. FieldSight Pro generates professional, company-branded PDF and editable Word inspection reports. The Basic Suite provides PDF calculation exports for its API 653 calculation tools.
Do my clients need a FieldSight account to view an interactive report?
No. Recipients can open a finalized interactive report through its controlled public link in any modern web browser. No FieldSight account or additional software is required, and a PDF download remains available.
Does FieldSight support API 653 Annex B settlement evaluations?
Yes. FieldSight supports API 653 Annex B settlement evaluation workflows, including calculated results and report-ready output for inspector review. Annex B Settlement is available as an optional Basic Suite add-on and is included with FieldSight Pro.
Can I use my company’s branding on reports?
Yes. FieldSight Pro supports company logos, colors, contact information, report styling, and sign-off details so finalized client deliverables consistently reflect your company’s branding.
What is the difference between the Basic and Pro suites?
The Basic Suite focuses on API 653 calculators, saved jobs, and PDF calculation exports, with Annex B Settlement and the Tank Diagram Builder available as optional add-ons. FieldSight Pro adds the complete inspection workflow, includes Settlement Engine and Diagram Builder, and carries inspection data through engineering evaluations, findings, photographs, branded PDF and Word reports, interactive client sharing, and team controls. The 30-day Pro Solo evaluation is a $99 one-time purchase, requires a card, and is not a free trial. Existing FieldSight customers use their same account and data, and a paid Calculators subscription remains active during the Pro evaluation.
Create your FieldSight account and choose the tools that fit your work—from API 653 calculators to the complete inspection, reporting, and client-delivery workflow.
