.... INTRODUCTION So far, three classic spars, Neptune, Genesis and Hoover, have been installed for dry tree applications with deep draft 198m (650 ft). After Hoover spar installed on 2000, spar designs evolved into truss spar and cell spar. variation good agreement hurricane floating production system...

... rough sea scenario, Hurrican Juan, has been selected to evaluate the two ship interaction seakeeping behaviors in deep water and in shallow water. The comparison results have been presented and discussed. INTRODUCTION Two ships operating in close proximity can be found from the operation of ship...

... of fuzzy-neural hybrid systems expressed by a union Gaussian function in terms of two independent parameters were studied and then typhoon waves decaying due to land effect was well described by a model (Hsien-Kuo Chang, 2006). It is possible to determine an equivalent fetch for a hurricane which...

... to evaluate the survivability of the platform in 100-year hurricanes. Higher-order boundary element method (HOBEM) has been utilized to generate the first- and second-order wave forces on the platform and its motions were predicted by a frequency-domain method. It was found that the optimized motions can...

... ABSTRACT The source terms of wind input, depth-induced wave breaking, and bottom friction, in the SWAN wave model, are investigated with NDBC buoy data during two hurricane processes in Carolinas coastal ocean. It is found that SWAN results with Komen wind input are more consistent with buoy...
