The creation of a clash free, error free design will still leave a project open to considerable risk unless the fabricated parts match the design intent. If newly fabricated components do not fit, ongoing work may be delayed and rework may be required. Using laser scanning, Quest Integrity can identify fabrication errors, allowing variations from design to be easily detected and visualized.
In a fabrication verification process, spool pieces are scanned in the fabrication or laydown yards. They are compared to the design intent to be sure that they will fit properly. Blunders and missing connections can be quickly found and efficiently addressed before the parts are shipped.
Quest Integrity can provide reports which verify individual spool pieces or entire lines. Flange center, bolt rotation, flange skew and critical design lengths can all be identified. Moreover, a full set of fabricated spools, valves, fittings and gaskets can be shown to mount together and fit within the assembly tolerances of the tie point coordinates.
This fabrication verification process is extremely valuable during refinery turnarounds, offshore platforms and is becoming commonly used in other onshore facilities as well. By verifying fabricated items match design, our clients have been able to reduce field fit-up welds and eliminate fabrication clashes saving time and money.
