122578 - Development of 3d Dimensional Inspection Methods for Pressure Vessels Using Portable, Non-Contact, Infrared Laser Type 3d Scanner 

During factory inspections of pressure vessels, there are many cases of missed allocations of attachments such as nozzles, clips and saddles. These oversights typically come to light during the installation of piping connections and/or platforms at the construction site, following the installation of the pressure vessel. Addressing this misallocation has led to a notable impact on project schedules and costs. The lack of comprehension in dimensional requirements of pressure containing equipment by fabricators causes these troubles. Additionally, oversights in verifying these requirements by inspectors prior to equipment shipment also contributes the issue. Accuracy of dimensional inspection result using conventional manual measuring depends on skills of inspectors especially for large pressure vessels. In addition, it takes a several days to prepare inspection report with prevalent method.

In order to address these issues, a recently advanced and rapidly evolving technology, the non-contact infrared laser type 3D scanner, is introduced for the purpose of "3D Dimensional Inspection" within the oil and gas industries. Advantages of infrared laser type 3D scanners are lesser initial investment and more portable with lesser restriction of regulations for international transportation against stationary laser type scanners.

This paper presents trial results inspected pressure vessel dimension and discusses the advantages and disadvantages of the 3D Dimensional Inspection. The prospects for its future application to project execution is introduced.
