3D Laser Scanning & Reverse Engineering for Brownfield Plant Revamps

Brownfield plant modifications frequently suffer from outdated 2D drawings and undocumented field modifications, resulting in expensive site clashes and extended crane downtime during turnarounds.

1. Sub-Millimeter Reality Capture MacProtec utilizes high-precision terrestrial LiDAR scanners and mobile SLAM sensors to digitize congested processing plants: - Capturing over 2 million spatial coordinates per second with ±1mm accuracy. - Geo-referencing point clouds to existing plant datum systems and coordinate grids. - Eliminating manual measurement errors in high-temperature or inaccessible plant elevations.

2. Intelligent As-Built 3D CAD Modeling Raw spatial point clouds are transformed into parametric 3D CAD models: 1. **Clash Detection & Clearances**: Running clash simulations between proposed new equipment and existing structural steelwork or pipe racks. 2. **Spool Pre-Fabrication**: Generating isometric spool drawings with 100% fit assurance prior to site delivery. 3. **Equipment Rigging Simulation**: Verifying crane lifting paths and clearance envelopes during heavy equipment placement.

3. Measurable Plant Revamp ROI - **Site Rework**: Reduced piping and structural field modifications by 94%. - **Downtime Savings**: Shaved 11 days off critical-path shutdown turnaround schedules. - **Safety Assurance**: Minimized scaffolding requirements and personnel exposure in elevated plant zones.
