Abstract

With the disclosure of more and more Marine investigation accident reports, it becomes a new way to study ship collision characteristics through big data of ship collision accidents. In this paper, based on the big data of ship collision accidents, a radar window risk of ship collision (ROC) cognitive model based on Kriging interpolation and the Gaussian mixture method (KGMM) is constructed to study ROC characteristics. First of all, the spatial and temporal feature perception model of collision risk perception is established under the radar window. Secondly, a method based on KGMM is constructed. The method includes two parts which were data set interpolation using the Kriging interpolation method and the Gaussian mixture clustering method to cluster the interpolation results. Finally, different collision scenarios were set for 101 cases, and the spatial-temporal differentiation characteristics of ROC are identified by the ROC cognitive model in the radar window. The results show that the ROC presents a risk-sensitive area under the radar window. The characteristics of the risk-sensitive areas of different ships in the encounter situation are consistent with the overall characteristics. The research results can provide a reference for the ship officers to choose the low-risk and favorable position to avoid the ship under Convention on the International Regulations for Preventing Collisions at Sea (COLREGS).
