Live-fire exercise (LFX) areas at sea threaten the safety of ships, whereas, and indiscriminately abandoned unexplodedbombs threaten the lives of fishermen. No statistical or scientific research has been conducted on the appropriate locationsfor LFX areas. Therefore, this study proposes a method for effectively arranging the LFX areas at sea that considersthe safety of passing ships and national security. First, the proposed method classifies ship tracking data collectedin the daytime based on the dawn and dusk times of the civil twilight phase. Second, the method uses a Geohashgeocoding process to identify whether an LFX area coincides with the daytime traffic area of the vessels. Finally, a gridsearch was conducted, in which the polygons of the LFX areas that required rearrangement were shifted by appropriatelysetting the search range. The methodology presented in this study can be used as a guideline for designing safe LFXareas at sea.
