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.

Abstract

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.File in questo prodotto:
