摘要：

In this work, the roll damping behavior of the offshore heavy lift DP3 installation vessel Orion from the DEME group is studied. Boundary element codes using potential flow theory require a roll damping coefficient to account for viscous effects. In this study, the roll damping coefficient is calculated using the Computational Fluid Dynamics (CFD) toolbox STAR-CCM+. Firstly, the CFD model setup is validated by performing roll decay tests and comparing the results with experimental scale model tests in a towing tank. Secondly, the roll damping is assessed by the Harmonic Excited Roll Motion (HERM) technique for various excitation frequencies and for different forward speeds. These high-fidelity full-scale simulations result in better estimations of roll damping coefficients for various conditions. This enhances the accuracy of efficient Boundary Element Methods (BEM) codes for wave-current-structure interactions simulations.
