ARCHIMEDES
AI-Powered Process Engineering Calculations
Engineering calculation software that replaces spreadsheet-based process calculations with auditable, code-compliant, AI-assisted computation — from pressure relief sizing to heat exchanger design, all traceable to ASME, API, and applicable standards.
Calculations That Are Traceable, Auditable, and Standards-Aligned
Engineering calculations at refineries live in thousands of Excel spreadsheets — unversioned, unvalidated, and invisible to OSHA PSM auditors. ARCHIMEDES replaces this scattered approach with a structured calculation environment where every result is traced to the specific code edition used, the input assumptions, and the engineer who ran it. This isn’t just better software. It’s a PSM program defense.
Pressure Relief Sizing
API 520/521/526-compliant relief device sizing calculations with automatic code edition tracking, scenario documentation, and stamping data export.
Heat Exchanger Design
TEMA-aligned shell-and-tube and air-cooled exchanger calculations. Fouling allowances, tube count optimization, and ASME VIII pressure rating verification built in.
Hydraulic Analysis
Pipe flow, pump head, and pressure drop calculations with Darcy-Weisbach, Hazen-Williams, and Crane TP-410 methods — all traceable to the reference edition used.
Fired Heater Analysis
Process-side heat duty, tube metal temperature, and radiant section efficiency calculations aligned to API 560 and ASME heater standards.
Calculation Package Export
One-click export of complete calculation packages in audit-ready format — input sheet, methodology, code references, results, and engineer signature block.
AI Calculation Assist
Describe the engineering problem in plain language. ARCHIMEDES identifies the applicable calculation method, pulls the right code sections, and runs the computation with your inputs.
Spreadsheets Are a PSM Audit Liability
- OSHA PSM requires documented, reviewed engineering calculations for mechanical integrity
- Spreadsheet calculations have no version control — auditors can’t verify the code edition used
- Relief device sizing spreadsheets are frequently out of date with current API 520 editions
- ARCHIMEDES generates a complete traceability chain from input to code reference to result
- Calculation packages are formatted for inclusion in PHA documentation and MI records
- AI-assisted calculations reduce the time to produce a compliant calculation from hours to minutes
Platform Details
ARCHIMEDES is designed as a Windows desktop application with optional network shared library for teams — consistent with the same offline-capable architecture as NORMEX Standards AI. Your calculation inputs and proprietary process data never leave your facility.
Replace your calculation spreadsheets with something defensible.
