There is a need to study the evolutionary laws of the risks in the navigation environments of complex marine areas. This can promote shipping safety using an early-warning system. The present study determines shipping flows and meteorological conditions in a marine area on the basis of meteorological and automatic identification system (AIS) data....

... calculating and analyzing the impact probabilities of each accident case, their distribution remained unknown. Nevertheless, using the statistics of all possible navigational environment conditions (i.e., the whole sample), the accident case impact probability, and the full sample, the impact probability distribution diagram was drawn, as shown in Figure 6. . Variations in impact probabilities with navigational environment impact factor level. ...

Nevertheless, using the statistics of all possible navigational environment conditions (i.e., the whole sample), the accident case impact probability, and the full sample, the impact probability distribution diagram was drawn, as shown in Figure 6. It can be seen in Figure 6 that when the impact probabilities were sorted, the impact probability distribution of the accident cases was mostly concentrated in the upper part of the whole sample, which is consistent with the usual subjective perception of risk; that is, the higher the impact probability, the higher the probability that an accident will occur. ...

... Thus, flange and shaft can be connected by using chamfers as shown in Fig. 1a. Due to the frequent changes of winds, waves and currents and other geographical environment and navigational status of ships during sailing [1], the main shaft could be subjected to cyclic torsional and bending loads, and the structural inhomogeneity could also lead to the occurrence of elastic stress concentration effects. This main shaft with one notch for research purpose can be shown in Fig. 1b, T is the torque, D is diameter of cross section of smooth part of the specimen, d is diameter of cross section of notch part, h is the radius difference of cross section between smooth part and notch part, and ρ is curvature radius of the u-notch. ...
