A method of determining and visualizing safe motion parameters of a ship navigating in restricted waters
Abstrakt
The paper presents a method of displaying ship collision avoidance information which is based on an unconventional Collision Threat Parameters Area (CTPA) technique. The solution presented here extends CTPA's functionality from past works by supporting navigation in restricted waters and handling ship domains analytically instead of numerically. It visualizes potential navigational threats as well as possible collision avoidance manoeuvres. The proposed method provides three types of information: targets' motion parameters (typical for target tracking), combinations of own course and speed which collide with those targets (typical for CTPA displays) and combinations of own course and speed which collide with stationary obstacles (new elements). Optionally it is also possible to display only manoeuvres compliant with International Regulations for Preventing Collisions at Sea (COLREGS) for the present visibility conditions. A superposition of all these types of data enables a navigator to quickly choose an efficient collision avoidance manoeuvre. The paper includes a description of the proposed visualization technique as well as examples of visualised data for encounter situations, which demonstrate the proposed method's usefulness.
