Hydrodynamical loads on a floating dock towed in sea conditions

Abstract

Response amplitude operators (RAOs), short-term and long-term predictions of hydrodynamical response of a floating dock towed in conditions of Baltic and North Sea, are presented and analyzed. The research was focused on: heave and pitch motions, dynamic pressure induced in different parts of the dock’s bottom, vertical bending moment and resistance of the dock towed in head seas. The RAOs of the considered responses were determined by means of model tests and/or a computer calculation program based on strip theory. Discrepancies between so obtained values of the characteristics and predicted values of relevant responses, calculated on their basis, were indicated.
