ON THE PRACTICAL EVALUATION OF HYDRODYNAMIC COEFFICIENTS OF SEMISUBMERSIBLE PLATFORMS, BASED ON SYSTEMATIC MODEL TESTS

The paper summarises the results of an experimental investigation of the hydrodynamic coefficients in motion equations for prediction of catamaran-type semisubmersible platform's behaviour in waves. Using the method of forced oscillations, the effect of hull geometric characteristics, fluid viscosity and oscillation frequency on added masses and damping coefficients have been calculated for a series of semisubmersible drilling platforms (SSDP) models. Particular attention has been paid to the semisubmersible's hydrodynamic characteristics at horizontal motion in the low frequency range. The data obtained have been processed by regression analysis for use in computations of the dynamic and kinematic characteristics of free-floating and anchored offshore structures in waves.
