The adoption of RANS techniques is widely spread in terms of resistance and self-propulsion prognosis for merchant and military vessels; however, on the other hand, the captive evaluation of hydrodynamic manoeuvring forces across numerical procedures still concerns great computational effort and challenge. When it comes to deal with Escort or...

The purpose of this study is to investigate the feasibility of a simple but robust approach for the identification of the main interaction effect of hull and propeller on the rudder inflow in a conventional manoeuvring simulator. The manoeuvring simulator adopts a modular/MMG based approach in which the hull, the rudders and the propellers are...

an Azimuth Stern Drive Escort Tug. This study is devoted to identifying a proper mathematical model to be included in a dynamic manoeuvring simulator. The hydrodynamic problem is therefore decomposed in the hull and skeg components. The hydrodynamic characteristics of the skeg were so explored by varying its span and chord systematically,...

An industrial-academic collaboration between Rosetti Marino shipyard and University of Genoa presided over a deep theoretical and experimental insight into the maneuvering performances of a new escort tug family. The presented z-drive azimuthal stern drive class is characterized by high intact/damage stability margins, good maneuvering...
