Module Inspection Using Glove Fit
Oil & Gas
Problem
A Canadian fabricator needed to quickly and accurately inspect a module that was fabricated in their shop. Traditional and manual measurement tools were used throughout the fabrication process. The fabricator needed the inspection to be fast, accurate, and provide feedback that was easy to understand for workers on the fabrication floor. It was determined traditional Dimensional Control (DC) methods were too time-consuming and the fabricator chose Glove Fit for fast QA/QC on the module.
Objectives
1. Perform quick inspection on the module
2. Find and fix erroneous parts on the module
3. Complete fabrication on time
Challenges
1. Typical Dimensional Control approaches were too time-consuming
2. The geometry of the module was complicated
3. Constraints of resources and build time
4. Accuracy is impeded; cannot rely on measurement tools used throughout the fabrication process (tape measures!)
Solution
The Fabricator used Glove Fit (Glove Software) to scan the module and compare the resulting image with its design model to detect all deviations.
A FARO Focus laser scanner was used to scan the module, which then generated an exact digital version of the module into Glove Fit, an easy-to-use point-cloud measurement program by Glove. The result of the FARO scan is shown next to the 3D model of the module in the Glove Fit application.
Results
Utilization of Glove Fit allowed the fabricator to get to their results under 2 hours!
Glove Fit was able to quicky detect a major error. The fabricator was able to immediately detect a major deviation on one of the pipes. The fast feedback allowed for timely remediation on the module. This quick inspection in-turn saved the fabricator more than $10,000 worth of back charges and onsite delays.
The feedback is provided by the initial overlay as well as a deviation analysis using Glove Fit.
