Experimental Study of Hydrodynamic Responses of Cylinder Floating Production and Storage Offloading in Short-Crested Waves

Abstract

An experimental investigation is conducted to study the hydrodynamic responses of cylinder floating production storage and offloading (FPSO) subjected to heading short-crested waves of different spreading parameters. The motion response and mooring dynamics of cylinder FPSO are analyzed and the results are compared with those from the long-crested waves. The simulation experiment shows that the short-crested waves induce smaller surge motions and mooring tensions, but generate bigger sways and roll motions compared with those of the long-crested waves. There are statistically significant differences in hydrodynamics of cylinder FPSO between short-crested and long-crested waves. The research results provide important references for further study of short-crested waves and their interaction with ocean engineering structures.
