WAVE-DRIFT DAMPING OF A TURRET MOORED SHIP

Aanesland, Karl Erik Kaasen, Jørgen Ranum Krokstad

Abstract

A method is presented for calculating the wave-drift damping in the horizontal plane for a turret moored ship. It consists of a combination of a full three-dimensional panel method for the damping contribution in surge and sway and a strip theory approach for the yaw motion. The results are intended used in simulation programs for calculating low frequency motions and extreme loads in a seaway. A parameter estimation method is proposed for estimating slow-drift damping from experiments. The linear and nonlinear damping coefficients are estimated in combined surge, sway and yaw motion from decay tests.
