Abstract

Aiming at the south China sea semi-submersible platform, by using FEA simulate method,the wave parameters were studied in its extreme cases. According to ABS (American Bureau of Shipping) rules and DNV ( Det Norske Veritas) rules,the parameters of four extreme cases were searched and found by using stochastic method, such as case of the maximum rent force between buoyant hulls, case of the maximum fore-and-aft shear force, case of the maximum torsion and case of the maximum fore-and-aft vertical bending moment,which were used to calculate the surface loads distribution of this platform.
