With the development of water transport, there is a rapid increase in maritime traffic density. Therefore, navigation security should be given adequate attention. In this study, a risk evaluation system combining wind field model, wave model and standards of risk grades was proposed and applied in the Qiongzhou Strait (QS), China. Based on meteorological data, a wind filed model was established by Fujita–Takahashi formula and was verified using observed data set of typical typhoon process. Then, a simulation wave nearshore wave model which was used to simulate the significant wave height (SWH) was established with bathymetry data. In addition, through the analysis of the types and quantities of wrecks and ships in the research area, the typical ship was selected and classified by tonnage. Combining the as low as reasonably practicable with wind speed and SWH, the risk evaluation system for navigation security was proposed. Applications on QS showed that the system could provide an hourly reference of risk grades to water traffic safety early warning. Also, the conclusions of this study could serve as recommendations for Maritime Administration to manage navigation safety.
