The maneuverability, besides the security and economy, is another factor to evaluate on the routing of naval vessel. Aiming to the lack of the considering of maneuverability influence existing in traditional automatic shortest routing methods, this paper proposes a method for automatic routing based on comprehensive evaluation on limiting conditions of maneuverability. The proposed method has defined...
Aiming at the drawbacks of traditional static methods not considering dynamic changes of depths on a chart, the paper proposes a method for determining the navigability of a planned route based on an instantaneous depth model. Firstly, Instantaneous water levels are forecasted based on a grid tide model and incorporated into depths in a chart, and obstacle areas are acquired dynamically with changing...
A shortest routing is crucial in emergent navigations including rescue and military applications. This paper proposes an automatic method of the shortest routing for emergent navigation. Firstly, un-navigable shallow areas are obtained by tracing safety contour for the ship navigation, and they are processed together with other obstacle areas. Then navigable paths are tested based on the predefined...
