Abstract

Land fire receives additional extinguishing methods easily by professional extinguisher. But because of isolation and independence from land when sailing on the sea, ships are difficult to get special help from land. Generally, the death ratio by suffocation is higher than the death rate by flame and to reduce suffocation death ratio, fast evacuation is required. This paper aims to improve survival ratio at ship fires by soot density reduction. This study examines soot density and visibility using FDS. And also examines evacuation time by Pathfinder. The FDS(Fire Dynamic Simulator) is a 3 zone model(Field Model) analysis tool and the patherfinder is a useful analysis tool for evacuation. This research examined about evacuation time using the current regulations of the ship's corridor width and exit width first. And then studied evacuation time again when ship's structure was changed according to the method that is proposed in this paper. And finally compared the results each other.

선박은 충돌로 인한 침수, 화재 등 여러가지 이유로 긴급피난을 감행해야하는 경우가 많다. 특히, 선박의 경우 그 구조의 특성상 좁고 미로같은 복잡한 형태로 구성되어 신속한 탈출이 어렵다. 화재에 의한 인명손상의 경우 연기에 의한 질식사가 대부분을 차지하므로 신속한 탈출은 생존율 향상에 중요한 역할을 한다. 이 연구에서는 선박화재시 연기거동과 가시거리 확보 등에 대해 화재 분석 전용프로그램인 FDS(Fire Dynamic Simulator)를 이용하여 검토한다. 승무원 피난의 경우는 인간행동특성을 고려한 Pathfinder로 검토하였다. 이러한 분석 프로그램을 이용하여 기존 선박구조에 대한 화재확산과 승무원 피난시간을 검토하고 이와 동시에 변경된 구조가 승무원 피난에 미치는 영향을 검토하고자 한다.
