The prediction of non-linear motions and hull girder loads of an FPSO operating in extreme seas is of critical importance. 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 2-D or 3-D 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. In addition to the non-linearities due to large motions non-linear hull girder loads due to slamming and green water and low frequency motions due to the interaction between the incoming waves and the non-linear dynamic motion characteristics of an FPSO will be investigated through computational and experimental studies. The results of this study together with other projects within the programme on: FPSO Hull Structural Response in Extreme and Fatigue Sea conditions will make a significant contribution in the establishment of a reliability based design and assessment methodology.
