The study of maneuverability hydrodynamic of damaged ship in yawing motion has not been found, although maneuverability hydrodynamic of damaged ship is a major and difficult issue. In order to predict damaged ship maneuverability in viscous flows, the continuous equation, the Reynolds-averaged Navier-Stokes (RANS) equation, and the SST k-w turbulence model are chosen to calculate the hydrodynamic force coefficients of yawed 29000 ton oil tanker in intact and damaged conditions, respectively. The total resistance, transverse force, bow wag moment and distribution of total pressure of body surface are calculated during the oil tanker ship navigating in different yawed degrees. The results of numerical calculation in the conditions between intact ship model and damaged one are compared, while the streamlines and path lines around the damaged cabin are described. The numerical results between the intact ship model and the damaged one are agreed with the truth after qualitative analysis combined with correlative references and practice. The research, which is innovative, indicates that SST k-w model applied is reasonable and credible, and the maneuvering hydrodynamic forces and flow fields in damaged condition are different from those in intact condition in due to the effects of flooding of damaged compartment, and the numerical results are of great significance for ship designers and ship commanders.
