The authorities conducted an overnight search to find the three missing crew members of the 127 Oceans, which sank off the coast of Geoje-si, Gyeongsangnam-do.
The Tongyeong Maritime Police Department said that although it expanded the search range to a 20km radius and mobilized 21 patrol boats, it did not find any missing persons.
A storm warning has been issued on the water at the accident site.
The unfavorable weather, such as a wave height of 2 to 3.5 meters and strong winds of 10 to 16 meters per second, makes the search more difficult.
The water temperature at the site was recorded at 12.3 degrees, a little from around 15 degrees in the afternoon on the 23rd of yesterday.
According to the Marine Vessel Accident Crisis Response Manual, the maximum survival time for a missing person in an ocean accident is 25 hours.
The Coast Guard is planning to further expand the search network by mobilizing aircraft, etc.
