Influences of site specifics on passing ship effects Conference Paper uri icon


  • This effort explores the nature of passing ship effects as observed by a moored ship perpendicular to the ship path in confined shallow water. A Chimera, Reynolds-Averaged Navier-Stokes based viscous flow solver in conjunction with a three dimension motion tracer was used to address the hydrodynamic couplings between the passing and moored ships. This paper articulates the influences of basin geometry, ship layout, speed and standoff distance of passing ship, and mooring properties. Several unique trends are observed in the fluid forces induced by the passing ships with the moored ship perpendicular to the ship path. Most of the differences from the observations with moored ships parallel to the ship path are associated with large scale flow patterns governed by the overall geometry of basin and ship layouts. Evidences are illustrated in excitation forces on the moored ship. The radiation forces due to the motion of the moored ship are as significant as the excitations. A seamless, self-sustained simulation procedure is required to preserve the phase relations of the radiation forces.
