Wind tunnel testing is an almost universal practice in the design of floating production installations (FPIs). The results of these tests have been applied to many aspects of design; including mooring and stability analyses. This paper reports on the parametric study of six different FPIs that operate in the Gulf of Mexico and compares the results of the stability analyses based on wind moments determined with wind tunnel tests and wind moments calculated by the conventional Building Block Methodology. The results of this investigation are presented in the form of allowable VCG and relative effect of the topside weight capacity.
