MEASUREMENTS OF MOORING SYSTEM MOTIONS IN TIDAL AND OCEANIC CURRENTS AND THEIR ANALYSIS

In this paper, a drag coefficient of chained glass balls, to obtain the buoyancy force of a mooring system are determined on the basis of experimental data in the sea. Mooring motions are investigated by the lumped mass method using its drag coefficient. A taut mooring motion draws a circle in a rotating current, however, it draws a track like a figure 8 in an elliptically rotating current. Displacements of a taut mooring system can be estimated from current velocities based on two types of simple dynamical equivalent models. This makes measuring mooring systems easier than using an acoustical method.
