Best Practice : Use of Light Detection and Ranging for Ship Production
The University of New Orleans, College of Engineering has been conducting research on the use of Light Detection and Ranging for ship production.
The University of New Orleans, College of Engineering's (UNO COE’s) Gulf Coast Region Maritime Technology Center (GCRMTC) conducted research on the use of Light Detection and Ranging (LIDAR) for ship production. The LIDAR system is a unique technology that can take a three-dimensional (3-D) scan of an object through multiple scans. This system can be used to determine the accuracy and quality of as-built modules and complete vessels to greatly speed and improve the manufacturing process. It can also be used to obtain as-built drawings and perform reverse engineering on as-built subsystems.
The GCRMTC determined the Riegl LPM-25HA-C LIDAR as one system that is suitable to the shipyard production environment based on range, data collection rate, accuracy, and eye safety. Acquiring multiple scans of an object from different views is needed because LIDAR scanners can only capture data from one perspective. PolyWorks and MENSI 3Dipsos 2.4c software is being used to combine scans to form one-point cloud and produce 3-D models and conventional 2-D drawings. The accuracy of two mating assemblies that are to be fitted can be determined using PolyWorks IMAlign software. The alignment error as a function of position is graphically represented, and the alignment error can then be corrected.
Interior and exterior measurements of a ship or building and numerous other shipyard applications can be easily acquired through LIDAR. The GCRMTC plans to introduce and train the shipbuilding industry on the use of LIDAR.
