Why It Matters
In plant construction, quality inspection of equipment was previously conducted by the person in charge directly comparing drawings and manufactured products, which took a long time and could cause deviations depending on the inspector's skill level.
GS E&C announced on the 15th that it will promote digitalization of quality inspection by introducing 'Twyn', a digital inspection solution from Vizometry, a German augmented reality (AR) specialist company, to plant sites.
Equipment used in plant construction undergoes a quality inspection to check whether the design drawings match the actual manufactured product before installation on site.
Previously, the method in which the person in charge directly compared drawings and manufactured products was mainly used, so inspection took a long time and there was a possibility of deviations depending on the inspector's skill level. If quality defects are not discovered during the manufacturing stage, additional correction work may be required during field installation.
Twin, introduced by GS E&C, is a solution that allows comparison of 3D design information and actual manufactured products by overlapping them. Inspectors can use a tablet to compare the design model and the actual manufactured product on site to check whether they match.
The 'shape-based automatic registration and tracking' technology, which automatically matches the position and direction of the 3D design and equipment, is applied to compare the equipment shape captured by the tablet camera with the 3D design.
Through this, we first check for major quality abnormalities such as missing equipment, incorrect installation, and location/orientation abnormalities, and if additional verification is necessary, a detailed inspection is performed with a 3D laser scanner.
GS E&C expects to use AR-based inspection and 3D laser scanning in stages to reduce the time required for quality inspection and to increase the accuracy and efficiency of inspection by focusing on targets that require detailed inspection.
A GS E&C official said, "The biggest advantage is that we can quickly check for quality abnormalities and select objects requiring detailed inspection by directly comparing the 3D design model and the actual manufactured product on site. We will continue to increase the efficiency and reliability of plant quality management work by actively utilizing digital technology."
