Our QA Is the Product.
Not the Process.
Every weld, every dimension, every test result exists to cover surveyor's, insurer's, or yard PM's critical questions, months after delivery. We never skip tank verification, not under schedule pressure, not on simple jobs, not ever!

QA is never expedited
Schedule pressure never bypasses verification.
No tank ships without a signed test cert
It's our non-negotiable release gate on every job.
Documentation is a key part of fabrication
Missing docs = job incomplete regardless of tank status
Proof over promises
Specific claims backed by signed artifacts, not assurances.

How Every Tank Is Built
Each stage has defined checkpoints, sign-off requirements, and artifacts. A tank cannot progress to the next stage until the previous stage is documented and closed.
CAD Drawing & Approval
Every tank begins as a precision CAD drawing derived from a complete, verified intake. Envelope dims, fitting positions, baffle design, access plates, and mounting interfaces are resolved in the drawing, not improvised on the shop floor. Fabrication begins only after written drawing approval is received from the yard. This drawing revision becomes the contractual reference for what will be built.
Material Verification & Cert Capture
All incoming plate and fittings are checked against the material certificate before entering the production line. Heat and lot numbers are recorded, certs are filed against the job reference, and the traceability chain is opened. No material enters fabrication without a verified cert on file. This prevents traceability gaps that become impossible to reconstruct after the fact.
Nesting, Cutting & Dimensional Check
Plate is nested and cut to drawing. Critical envelope dimensions are verified against the approved drawing before welding begins. Any deviation at this stage triggers a design review and, if required, a change order. The impact ladder applies: changes after cutting carry higher cost and schedule impact than changes before the cut. This fact is communicated clearly at quoting.

Controlled Welding to WPS
All welding is performed to our internal Welding Procedure Specification (WPS), referenced to ISO 15614-2. Welder IDs are recorded on the QA traveler at every stage. Three defined in-process checkpoints: fit-up, root, and closure must be signed off before work proceeds. No weld stage is skipped, regardless of schedule pressure. Any rework is documented with root cause and corrective action before closure.
Visual Inspection & Dimensional Verification
Post-weld visual inspection covers all weld seams, fittings, access plates, and labels. The QA checklist records pass/fail against each inspection point with the inspector's sign-off. Standard Pack includes key envelope dimension verification. Assurance Pack extends this to a critical-dimension verification sheet with measured values recorded against the approved drawing - the "envelope-killers" that determine whether the tank fits first time.
Pressure / Leak Test
Every tank undergoes a leak or pressure test before any internal access plate is closed. The test method, pressure applied, duration, medium used, acceptance criteria, and result (PASS) are recorded on a signed test certificate. The tank's serial ID appears on the certificate, creating the immutable link between what was built, what was tested, and what was shipped. No tank leaves without a PASS on record.

Pack Completeness Check & EXW Release
No tank is released for collection until the Compliance Pack is complete and the release checklist is signed. This is a hard stop - not a guideline. A tank can be physically ready to ship and still be held internally because a photo is missing or a signature is absent. This discipline is what makes the pack trustworthy, so every document in it was produced when it should have been, not back-filled under pressure.
Photo Documentation & Serial ID
A photo record is produced at each stage of fabrication - pre-closure internals, weld stages, finished tank exterior, and close-up of the serial label. The Assurance Pack extends this to an expanded set with close-ups of critical features, fittings, and key interfaces. The serialized ID label is applied before shipment and becomes the permanent link between the physical tank and every document in the pack.

Nothing Ships Without These Five
A tank that holds pressure and has pretty welds on test day is not the goal. The goal is a tank that holds for the life of the vessel - in a bilge, in a refit, in charter service. That requires a controlled fabrication system, not a skilled welder and a prayer.

Schedule Pressure Is Not A Reason
Three scenarios yards try every year. Our response is the same every time. The alternative is a tank we can't stand behind.
"We accelerate scheduling. We never skip verification. That's how we protect your yard and our warranty"
"Skip the photos, just send it."
Photo documentation is not cosmetic. It is the only post-delivery evidence of what was inside the tank before closure, how the fittings were positioned, and what the label showed. Once a tank is installed and filled, these records cannot be recreated.
"Ship without testing. We'll test on site."
On-site testing after installation cannot replicate a controlled pre-installation test. The tank is in an enclosed space, fittings are connected to hoses, and a failure has consequences for the vessel and the people on it. There is no recovery from skipping this step.
"We don't need documentation."
The yard may not need it today. But the owner's insurer, their surveyor on the next refit, and the incident investigator six years from now might. Documentation produced at the time of manufacture is the only documentation worth anything. Back-filled records are legally and practically worthless!
