Abstract

A previously developed approach (Vishnubhotla, Falzarano, and Vakakis, 1998) was applied to a tanker based floating production, storage, and offloading vessel. This approach makes use of a closed form analytic solution which is exact up to the first order of randomness, and takes into account the unperturbed (no forcing or damping) global dynamics. The method was quite powerful and capable of handling rather general systems. Although the application herein required that the zeroth order solution to be known in closed form; this is not a requirement and actually it could be known numerically. The results demonstrate the effect of random external excitation and the amount of nonlinear roll damping on the global nonlinear roll dynamics of this vessel. However, Since the tanker is so large these rather severe seaways did not dramatically affect the manifolds. Nevertheless, the difficult to predict nonlinear viscous damping did not dramatically effect the size of the safe basin. This is an abstract of a paper presented at the 10th International Offshore and Polar Engineering Conference (Seattle, WA 5/28/2000-6/2/2000).
