This paper examines the applicability of formal safety assessment to the passenger ships. This is followed by an analysis of passenger ship characteristics and a proposed formal safety assessment methodology. Five interlocking steps are described to construct a safety model including novel risk assessment, cost-benefit analysis and decision-making approaches. A case study is carried out in order to demonstrate the proposed methodology. Further development in formal safety assessment in the context of passenger ship safety is finally discussed in detail.

Formal Safety Assessment(FSA) was introduced by the IMO as "a rational and systematic process for accessing the risk related to maritime safety and the protection of the marine environment and for evaluating the costs and benefit of IMO's options for reducing these risks". FSA can be used as a tool or a rule making process to help develope new rules and regulations. The purpose of this paper is to conduct a general review of the FSA methodology and to propose ways to use it in rule making process of machinery parts.

Formal safety assessment (FSA) is defined as a structured and systematic methodology aimed at enhancing maritime safety including protection of life, health, and the marine environment and property, by using risk and cost/benefit assessment or, more specifically, it is a process of identifying hazard, evaluating risk and deciding on course of action to control those risks. Emphasis is placed on the structural aspect of the failure of cargo hold. This study is expected to illustrate how a new methodology, i.e. the Formal Safety Assessment, can be applied to specific ship safety problems.

The prevention of marine accidents has been a major topic in marine society and various policies and countermeasures has been developed, applied to the industries. Formal Safety Assessment is a structured and systematic methodology, aimed at enhancing maritime safety, including protection of life, health, the marine environment and property, by using risk and cost-benefit assessments. In addition, it provides a means of being proactive, enabling potential hazards to be considered before a serious accident occurs. In this paper, we has been screening and ranking of hazards using fuzzy structural modeling method and quantitative risk assessment for the ship's collision in the last 10 years marine accidents.

이 연구에서는 국제적으로 관심이 집중되고 있는 FSA를 선박의 화재 안전 분야에 도입하기 위한 준비과정으로 화재안전도의 가장 중요한 지표인 사망확률의 근거가 되는 피난계산을 실습선의 모의훈련에 의해 계산하여 피난시간의 계산 및 성능기준 화재의 안전설계를 검토하였다. 그 결과 승선인원과 대피 통로의 폭과는 일정한 상관관계가 있으며 최적의 폭을 산정할 수 있음을 보였다. 그러나 선박 내부의 좁은 통로와 선박의 종류에 따른 특수한 구조를 고려할 때 일괄적인 적용은 어렵다. 또한 대피시간을 모의실험에 의해 추정하고 유출계수를 구한 결과 공용실의 유출계수와 비교하여 기관실의 인명위험성이 약 4배이상 높게 나타났다.

The risk management case is an organization's formal arrangement to ensure the safety of its work activity within risk management system. It allows an organization to demonstrate its capability in achieving its safety objectives and in meeting regulatory requirements. This paper presents how the safety assessments are described, prepared and maintained to meet the criteria specified by the upcoming safety regulations. We propose the elements of risk management system that include arrangements for the ongoing identification of hazards, assessment of risks and the implementation of necessary control measures.

Present-day rules and regulations for the design and construction of ships are almost without exemption of a prescriptive and deterministic nature. Often it is argued that this situation is far from ideal; it does no right to the advances, which have been made during the past decades in engineering tools in marine technology, both in methodology and in computational power. Within IMO this has been realized for some time and has resulted in proposals to use Formal Safety Assessment(FSA) as a tool to improve and to modernize the rule making process. The present paper makes use of elements of the FSA methodology, but instead of working towards generic regulations or requirements, a Risk Assessment Approach, not unlike a 'safety case'; valid for a certain ship or type of ship is worked out. Delft University of Technology investigated the application of safely assessment procedures in ship design, in co-operation with Anthony Veder Shipowners and safety experts from Safely Service Center BV. The ship considered is a semi-pressurized-fully refrigerated LPG carrier. On the basis of the assumption that a major accident occurs, various accident, scenarios were considered and assessed, which would impair the safety of the carrier. In a so-called Risk Matrix, in which accident frequencies versus the consequence of the scenarios are depicted, the calculated risks all appeared lo be in the ALARP('as low as reasonable practicable') region. A number of design alternatives were compared, both on safety merits and cost-effectiveness. The experience gained with this scenario-based approach will be used to establish a set of general requirements for safety assessment techniques in ship design. In the view that assessment results will be most probably presented in a quasi-quantified manner, the requirements are concerned with uniformity of both the safety assessment. These requirements make it possible that valid comparison between various assessment studies can be made. Safety assessment, founded on these requirements, provides a validated and helpful source of data during the coming years, and provides naval architects and engineers with tools experience and data for safety assessment procedures in ship design. However a lot of effort has to be spent in order to make the methods applicable in day-to-day practice.
