Verification Services

Design Verification

Traditional engineering workflows can be enhanced through the use of laser scan data in the design process. The design verification work process results in the elimination of design error due to human error, omissions and dimensional uncertainty while enabling interactive design reviews, owner oversight of the design process, and the removal of field fit-up welds from the base design. The scan data and design coordinate systems are aligned, the design documents are overlaid into the scan data and discrepancies are determined through the use of clashing algorithms and validation processes.

By identifying and resolving design issues, Quest Integrity helps clients minimize design time, eliminate design clashes and reduce field fit-up welds.

Clash Detection

Piping Clash Reports review 2D isometrics or 3D CAD piping designs with the scan data to identify clashes and suggest resolutions, such as alternate routings or by locating likely flow line routings. This helps to ensure the piping can be installed with minimal or no clashes.

Interposing design models with the scan data is an effective method to find issues quickly before fabrication.

Fabrication Verification

Fabrication Verification

The creation of a  clash freeerror 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.
