PURPOSE: A multi-use collision risk identifying support system is provided to prevent possible collision accidents among vessels from taking place by effectively identifying a vessel's or several vessels' risk of colliding with other vessels. CONSTITUTION: An input unit (100) receives information about one or more passing vessels via Automatic Radar Plotting Aids (ARPA) or Automatic Identification System (AIS). A calculation unit (200) analyzes the received information and calculates out the nearest time, the nearest distance, and a collision risk of the one or more passing vessels. A display unit (300) displays the collision risk of the one or more passing vessels, which is calculated by the calculation unit, on an electronic navigation chart. [Reference numerals] (100) Input unit; (200) Calculation unit; (300) Display unit; (AA,EE) Latitude; (BB,FF) Longitude; (CC,GG) Course; (DD,HH) Speed; (II) Calculate the TCPA and DCPA of passing vessels; (JJ) Calculate collision risks among the passing vessels regarding their traveling directions; (KK) Calculate comprehensive collision risks among the passing vessels; (LL) Display the passing vessels identified by ARPA and AIS on an electric marine chart; (MM) Highlight the collision risks among the passing vessels with colors; (NN) Flicker the vessels with a high risk of collisions |
