The prediction of non-linear motions and hull girder loads of an FPSO operating in extreme seas is of critical importance for the assessment of structural integrity of the vessel. Although the non-linear effects due to large-amplitude ship motions and the associated hydrodynamic loads are generally recognised, the effect of different non-linearities on the prediction of hull girder loads and responses requires to be identified through systematic studies. FPSO hull girder loads are commonly calculated using ship classification rules or predictions based on linear two- or three-dimensional hydrodynamic theory with additional factors to account for non-linearity. The level of inherent uncertainty in these prediction techniques has to be identified through case studies. The paper presented here investigates the effect of non-linear load predictions on the ultimate hull strength assessment of an FPSO.
