There have been many accidents of passenger ships on the sea and they have caused a big loss of human lives. Maritime Safety Committee(MSC) of International Maritime Organization(IMO) made evacuation analysis of Ro-Ro passenger ships mandatory in order to save as many lives as possible at the time of accident. But this is a temporary regulation and HSC/IMO ties to introduce a performance-based regulation to improve the effect of regulation. Simulation-based evacuation analysis is the basis of performance-based regulation. In this paper, we performed a simulation-based evacuation analysis on a passenger ship, which is usually used in the plying between land and islands in Korea, with EXODUS system. Through inspecting the results from this analysis in more detail, we can make a proposal to improve the safety of passenger ship. Finally we describe the features of IMEX(Intelligent Model for Extrication Simulation), a new evacuation model being developed in KRISO.

For passenger vessels, twin shaft types in propulsion system is generally adopted to provide a high-speed performance in low draught due to restricted operating condition in harbors or water channels. Struts of twin open shaft type support the shafts, bearings, and propellers. Therefore, strut design is needed to consider not only hydrodynamic performance but also structural and noise/vibration performance, In this paper, considerations in strut design at the initial design stage have been discussed based on existing references, numerical calculations, and their comparisons. Also, the strut design of a RoPax ferry has been carried out at the initial design stage, for an example.

Recently, the Session of MSC $80^{th}$ has adopted the new harmonized requirements of damage stability for Passenger, Ro-Ro Passenger ship and Ory Cargo ship based on the probabilistic analyzing method reflecting the study of IMO for more than ten years. This paper introduces what have been changed in the SOLAS requirements about SDS (Subdivision and Damage Stability) and the results of investigation for design effects according to the new rules.

The paper describes a formalisation of a Design for Safety methodology in an integrated envi-ronment, outlines early developments of a software tool, and presents the results of an appli-cation of the methodology to a case study. The approach adopted attempts link safety per-formance prediction through the utilisation of appropriate technical tools, safety assessment deriving from risk-based methodologies and disparate design activities and issues. Black-board systems have been utilised as the platform in the development of the integrated design environment, allowing safety assessment to become an integral part of the design process. Finally, the case study addresses the application of the developed methodology to three dif-ferent arrangements of a conventional passenger Ro-Ro vessel, with the aim to demonstrate the validity of the process and methodology adopted. The findings are presented and dis-cussed, and recommendations given for the way forward.

All passenger ships aboard more than 36 passengers are to be able to easily find escape routes when the escape way by fire with flame spread were onboard vessel (incl. Ferry, Passenger, Ro-pax, Inland Ferry) It should be impossible by ordinary emergency lights. The international Maritime Organization (IMO) gives special requirement for luminescent evaluation onboard test procedure and applicable location of low location lighting. In order to maintain the residual light source for a certain time in the low location lighting with a strip-shaped light source, the light source material must be sufficiently exposed to the light due to the proper placement of the escape route. The lighting arrangement influence how maintain low location lighting strip luminescent which measured onboard in connection with what elements are mainly sustain luminescent.

A hull-form for a 32,000G/T class Ro-Pax ferry has developed in accordance with a need of ferry operators to reduce fuel oil consumption(FOC) due to the drastic increase in oil prices recently and strengthening of environmental rules and regulations such as CO2 emission. A twin-skeg type is applied as the hull-form in lieu of an open-shaft type in order to improve propulsion performance. In order to achieve this object, flow control devices are installed to reduce a propeller induced vibration which is a main reason to obstruct the application of twin-skeg type passenger vessels owing to an uncomfortable vibration level. Numerical simulation by using an in-house code and a commercial code (Fluent) has performed to find out an optimum design of the flow control devices and to check an improvement in cavity volume. Model tests in Samsung Ship Model Basin are carried out to evaluate propulsion performance with the developed twin-skeg type hull and a reference hull of open-shaft type. In conclusion, it is shown that the twin-skeg type hull is better than the open-shaft in FOC by around 7% and in cavity volume by 20% as well.

The 24th ITTC Specialists Committee on Stability in Waves is conducting an international benchmark study where numerical methods for the calculation of ship motion in damaged condition are compared on the basis of specified tests in order to assess the present state of the art in this field. The study is finished and some results are presented in this paper providing an initial insight into the status of damage models and numerical methods and a collective assessment of their performance. The preliminary analysis has shown that current methods are satisfactory, capturing the fundamental physical performance of damaged ships in specified conditions.

최근 여객용 선박을 즐기는 다양한 층이 확대되면서 일반 여행자들에게 공개하지 못할 공간 및 정보 등이 있다. 이런 이유로 특정 선박승무원 출입만 허용할 수 있는 보안시스템이 필요하다. 현재 보안시스템에 가장 많이 사용되는 생체인식 즉 지문, 홍채, 정맥 등 다양한 방법을 사용한다. 하지만 이 방법들은 흔적을 남기므로 또 따른 목적으로 사용할 수 있는 단점을 가지고 있다. 따라서 본 논문에서는 기존 암호입력 인터페이스의 문제점인 지문이 남는 위험을 방지하고자 손동작을 2차원 입력 영상으로부터 획득하여 손동작을 인식하고 3차원 영상 큐브를 이용한 암호입력 인터페이스 설계하고 구현한다.

In order to simulate the evacuation simulation of a ship during a sinking, the slope angle change of the ship must be reflected during the simulation. In this study, the passenger evacuation simulation is implemented by continuously applying the heeling angle change during sinking. To reflect crowd behavior, the human density and the congestion algorithm were developed in this research and the walking speed experiment in the special situation occurring in the inclined ship was conducted. Evacuation simulation was carried out by applying the experimental results and the change of the walking speed according to the heeling angle of the ship. In order to verify the evacuation simulation, test items suggested by International Maritime Organization (IMO) and SAFEGUARD Validation Data Set conducted on a large Ro-PAX ferry (SGVDS 1) which performed real evacuation trial in full-scale ships were performed and the results of simulation were analyzed. Based on hypothetical scenario of when a normal evacuation command is delivered to the passengers of MV SEWOL in time, we predicted and analyzed the evacuation process and the number of casualties.

Recently, the terror frequently has taken place for unspecified individuals as modern society is complicated. Especially, in case of a subway carriage fire as Daegu subway fire, because smoke spread path usually coincide with passenger's evacuation path, it will reduce visibility and can cause fatalities by asphyxiation. This study performs not only fire simulation with CFAST V6 but also evacuation simulation with EXODUS V4 for the purpose of taking measures for passengers's life safety in subway fire. As a result of evacuation simulation without fire, evacuation times are 36 s for EXODUS V4 and simple hand calculation, and when fire is occurred fire, 101 persons evacuated in 32 s. Therefore, a countermeasure of evacuation in subway carriage fire is required to repression of fire and emergency exit.
