The detection of potential collision situations by relative motions of vessels under parameter uncertainties in vessel manoeuvring is presented in this study. The detection process consists of the observations of the relative navigation trajectory and course-speed vector between two vessels. The proposed detection process is developed as a part of the intelligent navigation system that makes decisions under multi-vessel collision situations. A two vessel collision situation is considered and the extended Kalman filter algorithm is used in this study to estimate the relative navigational trajectory as well as the relative course-speed vector. Finally, prior and posterior collision/near-collision situations are simulated and successful simulation results on the detection of potential collision situations are also presented in this paper.
