Classification: CPC G | IPC G

Claim 15:
16. A collision avoidance system comprising:
at least one processor;
at least one memory storing computer readable instructions;
the at least one processor being configured to read the computer readable instructions to:
obtain real time data relating to a path of two or more vessels,
identify a collision risk between the two or more vessels,
determine if the collision risk is above a predetermined threshold,
when the collision risk is above the predetermined threshold, determine one or more collision avoidance manoeuvres by comparing the real-time data with historical navigational data corresponding to the real time data,
wherein the determining of the one or more collision avoidance manoeuvres is provided by a model having an input of the real-time data and an output of the one or more collision avoidance manoeuvres, and the outputs are provided by model parameters defined using the historical navigation data in which a historic collision risk between two historic vessels reduces;
wherein the model is an artificial neural network or polynomial expression; and
provide the one or more collision avoidance manoeuvres to an operator of one of the two or more vessels.
