Evaluation of the Risk of Collision Between Two Target Ships Based On Observation Data From A Third Party

Abstract

Detecting the risk of collision is a very important step to prevent marine accidents. For detecting the risk of collision, radar plotting is often used. Based on therelative position and motion of two ships, the risk of collision between them can be evaluated. However, the present radar equipmentis not supported to detect the risk of collision between two target ships from the observation data measured by a third party. This causes difficulties for officers of shore stations, when evaluating the marine traffic situation to maintain the safety of navigation.To solve this problem, it is necessary to develop a method to evaluate the risk of collision between two target ships from the observation data measured by the shore station radar (the third party). In this article, the development of such method is introduced..
