DAMAN – PTCS M&C - Giải Pháp Web/ App Tương Tác 3D/360


Currently, most of the offshore projects, oil and gas rigs, oil and gas exploitation rigs, petrochemical refineries, gas electricity fertilizer processing factories in particular and factories in general are designed in total. able and then divide and fabricate modules. Once the modules have been manufactured, they will be moved back to the installation location. Before that, the modules will be manufactured and manufactured by QA / QC units, according to the design drawings. Especially, the points that connect the components together need to be checked and evaluated for accuracy in the most detailed way. Currently, manufacturing units are using total stations to conduct tie-in points. However, the data collection by the total station takes a lot of time, the data collected from the total station must take many steps to be able to give the location of the assembly points. Calculation results from discrete data of total stations have not achieved high accuracy, especially for works such as pipelines, oil and gas rigs, spool assemblies, skit assemblies in factories, or combined pipe rack. As a result, the accuracy of the millimeter QA / QC must be conducted many times, consuming a lot of time, effort and affecting the project progress. Especially for oil and gas constructions, offshore constructions take place offshore so the parameters must be determined almost exactly.

Nowadays, with the development of 3D laser scanning technology and processing software, the identification of connection points, as well as assembly and simulation of after-fabricated modules are done in an easy way to save time. time and effort. Improve work efficiency and save operating costs. We have implemented a tie-in point identification and assembly simulation solution using 3D laser scanning technology for DAMAN rig base construction at PTSC port.

The first step of the solution is to use the Faro Forcus S350 long-range scanner, scan the entire DAMAN stand construction. With this project, we have placed four scanning stations around the site to collect data. Instead of having to aim from point one like a total station, the 3D laser scanner allows up to a maximum of nearly one million points within a second. So the data collection was shortened to about an hour instead of one or two sessions when using the total station.

The data collected will be put into specialized software to handle pairing scan stations together. The result is a point cloud model in 3D space of the building.

After the pairing is complete, the data is exported to a common format such as RCP, XYZ, … and proceeds to import this data into the software to determine the coupling points and assembly simulation
