In this article, a ship manoeuvrability-based simulation for ship navigation in collision situations is established. Under the general requirement from the Convention on the International Regulations for Preventing Collisions at Sea (COLREGs) and good seamanship, the determination of encounter situations is quantified to reduce navigators’ intervention. Meanwhile, the action manner by course alteration or changing speed in some typical encounter situations is graphically analysed for both the give-way and stand-on vessels. Then, the multiple genetic algorithm and linear extension algorithm are adopted to perform trajectory planning for collision avoidance. To improve the reliability of the simulation system, the mathematical model of ship motion and ship manoeuvring control mechanism are adopted, which can eliminate the insufficiency of neglect of ship manoeuvrability in the process of collision avoidance. Meanwhile, the course encoding technique is adopted to fit the ship manoeuvring control mechanism. Finally, a set of traffic scenarios emulating different encounter situations are applied to demonstrate the effectiveness, consistency, and practicality of this system.

“…The side force (toward the ship's port direction) and the clockwise turning moment (the ship's starboard turning moment), which are induced by the full astern engine, are assumed to be set up as 64 kN (6.5 ton) and 10,192 kNm (1040 tm) respectively, considering the diameter of the propeller and the number of propeller revolutions (Yoshimura and Nomoto, 1978). We also assume that the lag time to reach the full force of engine actuation and for it to be stopped is established as 60 s, empirically referring to seaman's knowledge, because it is very difficult to determine the effect exactly, and there is no information regarding this during the above tsunami situation.…”

“…Normal forces acting on the fins and rudders are basically estimated using a method for predicting the normal rudder force of ships (Yoshimura & Nomoto, 1978). Based on considering the symmetry of two pairs of fins and two pairs of rudders, the formulations of F F1 and F R1 are obtained as follows:…”
