Simulation Analysis on Passengers' Normal Evacuation Scenarios Considering the Changes of Heeling Angle during MV Sewol's Sinking (세월호 침몰시의 힐링각변화 조건에서 승객의 정상적인 탈출시나리오에 관한 시뮬레이션 분석)

  • Under the conditions of invested actual changes of heeling angles during MV Sewol's sinking, this study proposes passengers' evacuation scenarios, which are based on the assumption of normal orders of evacuation being given to the passengers, and evaluates using a marine-specialized human evacuation simulation tool. As results, when the heeling angle is set as 0 degree or 30 degree, it is found out that almost every passengers can success to evacuate to the musterstations, even though the evacuation times are different depending on the scenarios and the walking speeds. Meanwhile, when the heeling angle is varied as the Sewol incident, 3.1 %(Scenario Sc-Va which set chutes on port side as evacuation routes), 11.1 %(Sc-Vb, every open decks of port side as evacuation routes) and 20.0 %(Sc-Vc, every open decks of port and AFT sides as evacuation routes) among 476 passengers can successfully reach to the musterstations from their cabins with the condition of average walking speed as 2.04 m/s on flat. And only 0.8 %(Sc-Va), 3.8 %(Sc-Vb) and 10.7 %(Sc-Vc) can success to evacuate with the condition of average walking speed as 1.48 m/s on flat.

  • In spite of the methodology of evacuation process on vessels should be different comparing to the architecture on land, some have simulated the evacuations onboard ship with simulation tools which is developed only for the architecture. On this study, a vessel-oriented simulation tool is used to analyze the possibility of evacuation for a passenger ship. ${\cdots}$(중략)${\cdots}$ As a result of the simulation analysis, it is clear that the initial responding time and start-to-move time are so important, ${\cdots}$(중략)${\cdots}$.

  • Even though the passengers' safety has priority on Passenger ship, there is no criterion on the evacuation performance related with human behavior. To uncover the potential problems of domestic criteria on safety of passenger ships, this study performed simulation ad analysis the evacuees safety before and after the Sewol's remodelling. It is clear that the assembly stations of both before and after Sewol remodelling have sufficient areas to satisfy the domestic criterion by simply human- body's-area, but those are failed to assemble all the passengers by the simulation tool that reflects the human behaviors' characteristics. For the healing angle as 0 degree, and the criteria of SOLAS, it was found out that all the passengers can safely evacuate from each cabins to the embarkation stations for both of the before-and-after the Sewol remodelling. But for the healing angle as 20 degree, both of the before-and-after Sewol remodelling are evaluated as possible to make all the passengers evacuate for day scenario and impossible for night scenario of SOLAS criteria. And because of the worse conditions after the remodelling, the probabilities of Sewol(before) are showed wide band comparing to Naminoue (after).
