The ship domain in port areas: A case study in the Port of Rotterdam

Increased complexity on the waterway asks for more insight into distances between vessels. A method is created to determine the ship domain in a port area based on AIS data analysis. The method includes location, encounter types, relative position and ship-specific parameters.

Dynamic anti-collision A-star algorithm for multi-ship encounter situations

For the complex multi-ship encounter scenarios, this article proposes a dynamic collision avoidance path planning algorithm based on the A-star algorithm and ship navigation rules, namely Dynamic Anti-collision A-star (DAA-star) algorithm. A dynamic search mechanism of the DAA-star algorithm considering time factors is designed to enable the...

Integration of elliptical ship domains and velocity obstacles for ship collision candidate detection

The maritime shipping industry has been making significant contributions to the development of the regional and global economy. However, maritime accidents and their severe consequences have been posing an incrementing risk to the individuals and societies. It is therefore important to conduct risk analysis on such accidents to support...
