CFD Maneuvering Prediction of a Tanker Like Vessel

The turning circle maneuver of a self-propelled tanker like ship model is numerically simulated by means of the unsteady RANS solver Xnavis developed at CNR-INSEAN. The focus is on the analysis of the maneuvering behavior of the ship with two different stern appendages configurations; a twin screw with a single rudder and a twin screw, twin rudder with a central skeg. Validation of the predicted trajectory and the kinematical parameters is provided by comparison with experimental data from free running tests. Maneuvering abilities of the two configurations are discussed.
