The model system used in this example is largely similar to that in the CALM Buoy Offloading System example and is shown in the first figure below. A close up of the floating body finite element model is shown in the second figure. Fluid is transferred between a FPSO and a floating body (i.e. a CALM buoy) by means of a steel transfer line that hangs in a wave type configuration. The buoy is moored using chain and steel wire rope mooring lines. Because the main focus here is on the floating body motions, FPSO motions are not considered. Instead the end of the transfer line remote from the buoy is fixed throughout. There are no prescribed vessel motions applied to the floating body. Floating body RAO motions in heave, surge and pitch are determined for both regular wave and random sea states in the time and frequency domains. The hydrodynamic characteristics are determined from a WAMIT analysis.
