Abstract

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.

초록

원양어선 제501 오룡호는 황천 중인 베링해에서 조업 후 피항하던 중 개구부를 통한 침수로 인하여 침몰하였으며 많은 선원들이 사망하고 실종되었다. 본 연구에서는 사고선박 침몰사고의 진행상황 별 유동수 영향과 어획물 배치 등을 고려한 선박복원성 계산을 KST-SHIP (선박안전기술공단 선박계산시스템)을 사용하여 수행하고 사고선박의 침몰사고 시의 침수 후 선박복원성을 분석하였다. 먼저 만 재출항상태 (Full Load Departure Condition)에서의 사고선박의 비손상 복원성 계산서와 KST-SHIP을 사용한 비손상 선박복원성 계산 결과 를 비교하여 검증하고, 사고선박의 출항 시부터 사고 직전까지의 배수량에 따른 비손상 복원성 계산을 수행하여 비손상 복원성을 분석하였다. 또한 사고선박 침몰사고 시의 진행상황 별 침수 후 선박복원성 계산을 수행하여 침수 후 복원성도 분석하였다.
