SHIP MANOEUVRABILITY AND COLLISION AVOIDANCE

The paper describes some work conducted within a subproject of the newly formed Special Research Pool for Ship Technology (SFB 98) at Hamburg and Hannover. The author's team has developed an analytical model for computing collision rates by pitching collision avoidance capability versus demand in a statistically characterised traffic environment. The model accounts for both deterministic and random aspects of capability and demond. Deterministic aspects of collision avoidance making optimal use of manoeuvring capability are evalauted in detail using Isaac's theory of differential games. Here ships are modelled as circular discs moving with constant speed and freely controllable but bounded turning rate. Erratic use of manouvrability owing to misjudgement is modelled by solving nine different games ranging from optimal collaborative evasion to optimal collaborative rendezvous between two ships. Possible generalisations of the model are discussed.
