3D Scanning for BWTS & Scrubber Retrofit Projects
The Challenge
Ship operators face strict international regulations requiring the installation of Ballast Water Treatment Systems (BWTS) and Exhaust Gas Scrubbers. Retrofitting these systems into existing vessels is complex due to limited space, dense piping networks, and outdated or missing documentation.
The client needed a fast and reliable way to document existing conditions in engine rooms, pump rooms, and deck areas before engineering the retrofit.
Our Solution
- Deployed high-accuracy 3D laser scanning across machinery spaces, pump rooms, and deck piping.
- Captured every pipe, valve, and support structure with millimeter precision.
- Registered scans into comprehensive point cloud datasets.
- Delivered CAD-ready 3D models for retrofit design and clash detection.
- Supported engineering teams in planning layouts for:
- Ballast Water Treatment Systems.
- Scrubber Towers & Piping.
- Additional retrofits including fuel system modifications, deck piping rerouting, and structural supports.
(See images – on-site scanning, detailed piping scans, and point cloud models of retrofit areas)
The Results
- Seamless Integration: Engineers could virtually “fit” new systems into existing spaces without guesswork.
- Reduced Risk: Clash detection eliminated costly errors during installation.
- Efficiency: Surveys were completed quickly, without disrupting vessel operations.
- Compliance: Supported IMO environmental regulations and ensured retrofit deadlines were met.
Client Value
ScanPro’s 3D scanning services provided the client with accurate, up-to-date vessel documentation, enabling successful integration of environmental compliance systems. The result was a smoother, faster retrofit process, reduced time in dry dock, and long-term operational reliability.
Key Takeaway
Retrofitting ballast water and exhaust gas treatment systems requires precision and foresight. With ScanPro’s 3D scanning, shipowners and engineering teams gain the confidence to execute complex retrofits efficiently, safely, and in full compliance with international standards.
