Sažetak

In the present paper, numerical investigations was carried out on a 1:45 scaled model of DSI nine sided polygonal non-ship shaped FPSO, by varying different parameters of the model. Parameters such as inlet pipe radius, and moonpool radius was considered for the study and the variation of the RAO in surge and heave were plotted and reported in the present paper. Previously, experiment were conducted by the author on a 1:45 scale DSI nine sided polygonal non-ship shaped FPSO model with three different mooring arrangements viz. 100% turret mooring, 50% vessel and 50% turret mooring, and 100% vessel mooring. Author also conducted experiments on the model with different sizes of damping plates attached at the keel and skirt portion of the model to study its influence on the responses of the vessel and comparison was made with numerical result obtained from Wave analysis, MIT (WAMIT) software. Numerical study was carried out in WAMIT on the scaled model and the results were compared with those obtained from model tests in the wave basin.
