영문 초록

ECDIS provides safety function related to depth and contour lines to prevent grounding of ship. However, since the most ENCs contain depth contours at intervals of 2, 5, 10, 20, 30m, it is difficult to provide precise information to users and have limitations as a function of anti-grounding. Recently, the IHO recognized this problem and recommended the production of HD(High Density) ENC that provides depth contours at 1m intervals in confined water. In this study, spatial analysis was performed based on AIS and marine accident data to determine the depth contour ranges and areas required for HD ENC production. The study area was selected near Incheon and Pyeongtaek port on the west coast of Korea and depth contour lines with 1m intervals were created based on the TIN(Triangulated Irregular Network) interpolation algorithm and DEM(Digital Elevation Model) using the water depth data of the digital nautical chart. After that, the distribution of ship’s draft was analyzed based on the AIS data, and the spatial autocorrelation analysis using marine accident data indicates the need to provide dense contour lines in the fairway of Incheon and Pyeongtaek. It is expected to HD ENC that reflects the environment of the area and the characteristics of ships can help safe navigation of ships and prevent marine accidents.
