An Investigation into the Effects of Roll Gyradius on Experimental Testing and Numerical Simulation: Troubleshooting Emergent Issues

Abstract

This report presents the analyses, results and recommendations of an investigation into the specification and determination of a platform's roll radius of gyration and its influence on the measured or predicted roll response of a maritime platform. The investigation and report seek to resolve known deficiencies in the specification and determination of roll radius of gyration and provide direct guidance and supporting information to the experimenter and analyst to support ship motion analysis. Three solution sets were developed based on the results of the investigation. The solutions include: the establishment of a method of specifying roll radius of gyration requirements, the development of a decision tree tool to guide the analyst to the appropriate method of determining the roll radius of gyration and a set of system level technology solutions that enable the roll radius of gyration to be determined for model scale, full scale and virtual maritime platforms.
