... ABSTRACT Maneuverability is crucial for ship operators to understand the performance of escort tugs and improve seamanship. In this work, an escort tug model is taken as the studied ship. Oblique towing tests (OTT) are numerically simulated via the Reynolds-averaged Navier-Stokes (RANS) method...

... that the aerodynamic forces on the crosswind are affected by different container distributions. On the crosswind, the resistance coefficient and wind pressure coefficient show a linear relationship. The results can be used to ensure the maneuverability of the container ship on the crosswind, to prevent roll...

... and manoeuvrability, and is widely used in military and civil fields. Since the main hull has a strong influence on the resistance and maneuverability of the submarine, the optimization of the main hull should be prioritized. In the past, researchers often used the empirical mode of "modify-evaluate-re-modify...

... ABSTRACT Tugs have a simple hull form and good maneuverability. This paper works on the hydrodynamic performance of an ASD harbor tug with a skeg and bilge keels. Virtual oblique towing tests (OTT) and circular motion tests (CMT) are conducted via the Reynolds-Averaged Navier-Stokes (RANS...

... ABSTRACT With the new situation of inland ships maximization, the ship maneuvering is becoming more dangerous in restricted water. In this paper, a twin-propeller twin-rudder bulk carrier was chosen as the research object to study on the ship maneuverability in large artificial waterway...

..., furthermore the severity of ship conflict indicates the possibility of ship collision risk. Ship maneuverability, such as turning and braking and course changing and so on, is closely related to avoiding ship collisions. Firstly, a method determining minimum turn in crossing situation is built based on ship...

The maneuverability of the mining machine is thus a challenge while operating on the soft seabed. Predicting the traction of the mining machine and other associated parameters are very important for developing...

.... Therefore, it is necessary to understand the maneuvering behavior of a ship in waves in the viewpoint of ship safety in the design stage. According to ITTC (2008), the ship maneuverability in waves is of vital importance for navigation safety of seagoing ships. Various researchers have investigated...
