The CCG have collected 3D scan data to assist with engineering and maintenance work for several years now. We have also experimented with various 3D technologies and have started to receive new build vessel models as part of the as-built TDP. The CCG Integrated Technical Services (ITS) Marine Engineering (ME), responsible for the maintenance of CCG vessels, are looking for innovative applications for 3D data and tools to provide solutions to alleviate long-standing pain points. One of those pain points is the validation of TDP from new builds or Vessel Life Extension (VLE) projects to confirm that the TDP received is an accurate representation of the physical configuration of the asset in order to confidently use this data for future engineering and maintenance work.  Traditional TDP validation of a new builds is a manual process with inspectors physically on ship, validating 2D drawings prior to the acceptance of the vessel. The ME Mechanical Systems group wanted to see if it was possible to develop a process using the 3D model provided by the shipyard with the TDP package and 3D scan data acquired by CCG during the build process to validate/accept the traditional 2D TDP. This presentation will demonstrate the development this process for the fuel oil fill and transfer system on the Offshore Fisheries and Science Vessel (OFSV) as a first test case.
