The majority of marine vessels in service today do not have digital documentation or CAD models. Despite the fact that vessels currently under construction are designed based on 3-D data, they suffer the same lack of documentation of their true as-built geometries. Due to the inherent inaccuracy of the build process and the tolerances of the engineering techniques involved, there is always a mismatch between design data and reality. The actual as-built shape of the vessel, from the hull to the layout of internal features such as piping, does not accurately reflect design prints.

When they are due for any kind of fitting or refurbishing, the process is hit or miss as to whether new parts will fit and function correctly. Long-range laser scanning’s true-to-life modeling results offer marine engineers a way to ensure their vessels are built and modified correctly and safely the first time, saving them time and money.
