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....

... impact probabilities of environmental impact factors were calculated according to Equation (5), and the results are shown in Table 5. The variations in the impact probability with the impact factor level were plotted through analysis of the probability of natural occurrence in the case study ( Figure 5). The water environmental characteristics of the study area are shown in Figure 4. ...

The effects of the navigational environment on ship collision accidents in the study area are presented in Figure 5. It is clear that the impact probabilities fluctuated greatly according to the levels rather than having a single linear relationship. ...

... 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. ...
