AbstractIn October 1992, the Institute for Marine Dynamics (IMD) conducted a series of experiments with a 1:100 scale model of a Gravity-Based Structure (GBS). The experiments were performed in the Wave/Tow Tank at the Memorial University of Newfoundland (MUN). The primary purpose of the experiments was to demonstrate that the IMD has the capability to perform tow tests with waves and wind-induced moment, with measurements of model motions in six degrees of freedom, and bottom clearance in shallow water conditions. It was not intended that this be an exhaustive set of experiments which covers all combinations of drafts, tow and wind speeds, water depths, wave heights and periods, and towline geometries that might be specified in a commercial Request for Proposal. This report gives details of the model, the apparatus, and the instrumentation system. This report also defines the scope of the experiments and describes the experimental procedures, and finally outlines future experiments which would continue the study. This report presents the data in coherent form, and provides preliminary analysis of the data. This report makes suggestions for further analysis of the data and future experiments.
