API 650 AutoCAD Tank Drawings

I’m looking for someone who knows API 650 inside out and can translate that know-how into a clear, build-ready drawing set in AutoCAD. The job is to create a full package for an above-ground, vertical cylindrical storage tank with a working capacity of roughly 80 000 L.

What I need from you
• General arrangement showing complete tank dimensions and volumes
• Detailed fabrication drawings for shell courses, roof, floor, stiffeners, annular plates and ladders
• Material specifications that meet API 650 requirements
• Nozzle and fitting schedule with elevations, sizes and reinforcement details
• Bill of materials, weight summary and all relevant notes for fabrication and inspection

Delivery format
DWG (AutoCAD 2018 or earlier) and matching PDF sheets ready for shop use.

Acceptance criteria
Every sheet must reference the latest API 650 clauses, dimensions must close mathematically, and call-outs must be clear enough for a fabricator to cut, roll and weld without further clarification. One round of review is built into the scope; I’ll return comments promptly.

If you’re both an experienced drafter and comfortable acting as an API 650 checker, I’m ready to start right away.
