Deep-sea fishing vessel No. 501 Oryong was fully flooded through the openings and was sunk down to the bottom of sea due to the very rough sea weather on the way of evasion after fishing operation in the Bearing Sea with many crews dead and/or missed. In this study, calculation of ship stability was carried out using KST-SHIP(ship calculation system of KST), considering the effect of flow fluid and fish catch arrangement according to the progress of its sinking accident, and damage stability was analyzed. For this study, intact stability calculation of its accident ship under the full load departure condition and its calculation result were verified by comparing with each other, and intact stability according to displacement from the departure of accident ship just before the accident was calculated and analyzed. Damage stability was calculated according to the progress during sinking accident and also analyzed.

Deep-sea fishing vessel No. 501 Oryong was fully flooded through its openings and sank to the bottom of the Bering Sea. The tragic accident was attributed to rough sea weather after a fishing operation in the Bering Sea, and led to the death or loss of many crewmen. In this study, the ship stability calculation was carried out using KST-SHIP (ship calculation system of KST), considering the free surface effect and fish catch arrangement according to the progress of its sinking accident, and stability after flooding was analyzed. The calculation results obtained using KST-SHIP were verified by comparing them to intact stability calculation sheet of the accident ship under the full load departure condition, and intact stability according to displacement from the departure of accident ship up to the moment of the accident was calculated and analyzed. The stability after flooding was also calculated and analyzed according to the progress during its sinking accident.
