Documented Fuel Tanks Ready for Yard Sign-Off

Our workflow is designed for predictable fit, controlled scope, and clean handover. 
Lead times are committed only from a complete intake and an approved drawing revision.

1.  Intake & Constraints (RFQ)

We first evaluate complete tank envelope, access, fittings, mounting concept, and schedule requirements, so we could create a clear and precise quote and avoid fit disputes.

Input

  • GA / envelope + access constraints

  • Fitting list (fill/vent/pickup/return/sender)

  • Required date window + delivery terms (EXW)


Output

  • Complete RFQ confirmation

  • Clarification questions (if needed)

  • Quote-ready scope baseline

2. CAD & Design Review

We focus on CAD-first engineering -  fittings map, service access, mounting strategy, and practical installation are fully considered and included into the build.

Checkpoints

  • Access / serviceability
  • Vent routing clearances
  • Mounting & drainage approach


Output

  • Drawing Rev A that issued for your review and sign-off

3. Quoting & Lead Time

We quote from a point of a controlled deliverable: engineering + fabrication + selected certainty pack. Find out more about our  Certainty Packs, and lets together find the perfect fit for your project.

4. Drawing Approval Policy

We are guided by our strict policy - No cutting or fabrication begins until the yard approves the drawing revision in writing. It's how we convert uncertainty into accountable scope and protect your project from unwanted scope creep. We accept approval via email reply (“Approved Rev B”) or signature on drawing.

5. Fabrication & QA Traveler

Controlled fabrication with recorded checkpoints. Fit-up, welding stages, and final inspection are tracked on a traveler sheet.


Checkpoints

  • In‑process inspection points
  • Serialized Tank ID applied
  • Critical dimension checks (depending on the Certainty Pack)


Output

  • Completed fabrication traveler + inspection sign‑off

6. Testing & Compliance Assembly

Every tank is verified and documented. Period! We issue a signed test certificate and compile the Compliance Pack documentation agreed in the quote.

Release Policy

  • Non-negotiable type of policy (Critical Pack can't override it)
  • Passed test certificate
  • Serialized Tank ID + traceability references
  • Signed QA traveler
  • Pack completeness confirmed
