Modelling with process plan: 3D laser scanning allows operators to quickly and accurately model in the point cloud, which is particularly important when performing conversions. Consider tie-in flanges on a pipe. In that example, you must know exactly where that is down to a sixteenth of an inch.
The way it works is simple: operators pick two points on the scanned pipe and the software algorithms analyse the shape of the cylinder and determine the size of the pipe run. The software then models on the pipe using the predefined specification. Once the piping run is complete, it can be converted to solids.
Precision deployment: Scans uncover issues before maintenance teams can. In one instance, scans were analysed on behalf of a client, and it was noticed that fireproofing was falling off. With that information, the client’s repair crew knew exactly where the issues were and deployed to those locations without manually inspecting the entire facility.
Planning: Laser scan data is valuable for planning maintenance, construction, or decommissioning activities. For example, one frequent problem is fitting large equipment into an existing plant. Accurate drawings need to be reviewed but, in many cases, the original plans don’t show upgrades and changes. With laser scanning, a point cloud can be generated, and clash detection software deployed to guarantee the equipment will fit in advance of the project.
Large-part inspection: Consistent, accurate measurements are critical to maintaining design intent and performance of plant equipment, but it can be time-consuming and dangerous if done manually. Laser scanning takes precision measurements that minimise user variability and eliminates rework and scrap.
Decommissioning: Phasing out equipment, and plants is a time-consuming project requiring extensive documentation and verification. Once the project is underway, scanning can help owners and contractors document the entire process. And if environmental agencies are watching these remediation projects closely, detailed documentation is key. And laser scanning can get the job done in only a few hours.
Regulatory verification and documentation: Because 3D laser scanning creates an accurate digital representation of a site or project with a point cloud and photos, there’s an added layer of verification. A company can show regulators what is there before they inspect
Operator training: A company can create a virtual model of the entire plant to train employees, using the data the scans generate.
