| Summary: | With the increased frequency of shipping activities, navigation
safety has become a major concern, especially when economic losses, human
casualties and environmental issues are considered. As a contributing factor,
the sea state plays a significant role in shipping safety. However, the types
of dangerous sea states that trigger serious shipping accidents are not well
understood. To address this issue, we analyzed the sea state characteristics
during ship accidents that occurred in poor weather or heavy seas based on a
10-year ship accident dataset. Sea state parameters of a numerical wave
model, i.e., significant wave height, mean wave period and mean wave
direction, were analyzed for the selected ship accident cases. The results
indicated that complex sea states with the co-occurrence of wind sea and
swell conditions represent threats to sailing vessels, especially when these
conditions include similar wave periods and oblique wave directions. |
