Steep wave impact pressures and the structural dynamic response of FPSO (ship-shaped Floating oil Production Storage and Offloading vessel) bows are studied using 1/80 scale instrumented models and time domain simulation. The nature of the waves causing large impacts and the impacts themselves are discussed.
Simplified design rules for curved bows are proposed. The rules account for the effect of the size of the loaded area on the average pressure and the rise and decay times of the average pressure and hence the dynamic amplification of the response.
