Research on Theoretical Calculation and Simulation for the Maneuerability Index of Inland Navigation Ships
In recent years, with the flourish of the world’s seafaring, our country’s seafaring is rising rapidly. Our country inland waterways navigation mileage is up to 1.33 million kilometers, accounting for about 32 percent of the overall length of rivers. There are more than 1,300 inland ports in the nationwide, in which about more than 200 [...]
Calculation of Unsteady Hydrodynamic Forces on a Maneuvering Ship
The ability of ships to keep or change the speed, heading and position is the main research topic of ship maneuverability. Maneuverability is one of the most important navigational performances, which is closely related to navigation safety and efficiency. In order to ensure the safe navigation, it is necessary to predict ship maneuvering performances.One of [...]
Development and Application of Simulation Platform for Ship Maneuvering
Ship maneuverability is considered as an important index and relates closely to the navigation safety and economy. As the navigation abilities have been enhanced quickly,the transport quantity of ships increase so fast that the navigation conditions of waterway and navigation structures must be challenged with difficulties due to enlargement and rapid development of ships. In [...]
