This paper proposes an evaluation to Target Factor Values of Port State Control Inspections(PSCITFV) using AHP because PSCITFV is very simple methode, This AHP is the more rational and objective methode than existing TFV methode. AHP is relative measurement., but, weights should be re-calculation whenever alternative plan add. To this solve, therefore, this paper, used an absolute measurement and involved an marine casualty factor in PSCITFV, that IMO go ahead with it., Also, accomplished with evaluation some ships for the practice.

어선의 경우 어선운영자의 어선 자율정비 및 안전관리 능력이 미흡하고, 안전관리 수행 인력이 절대적으로 부족한 상태이다. 또한 어선 및 어선사업장의 지도 감독업무가 지방자치단체에 위임되어 있으나 인력 및 전문성 부족 등으로 개별어선에 대한 직접 관리가 곤란하여 어선 해양사고 예방을 위한 적극적 관리가 되지 못하고 있다. 따라서 국내 어선의 안전관리 현황과 문제점을 분석하여 수산업계에 대한 자율적인 안전관리체제의 구축 등 안전관리시스템 개선방안을 제시하고자 한다.

본 연구에서는 소형선박용 고속디젤기관의 고장으로 발생되는 해양사고를 저감하기 위하여 엔진의 상태를 사전에 기관운전자가 알 수 있도록 시스템을 구성하여 기존의 엔진에 이상이 발생하였을때 가시가청 경보를 울리는 것보다 한 단계 전에 엔진의 상태를 미리 알 수 있도록 하여, 기관의 고장으로 인한 해양사고 저감에 목표를 두고 과제를 진행하였다. 또한, 대형선박에서 사용하고 있는 고가의 고성능을 발휘하는 고장예측진단시스템은 많이 개발되어 있으나, 영세한 소형어선에 적용할 수 있는 소형의 저렴한 시스템 개발에 최종목표를 두고 1차년도 연구과제를 수행하였다.

In port and its approach channel, traffic accidents such as collision, aground, minor collision have reached about 77% of total marine casualty in the area. In this paper, an attempt to enhance the safe navigation was proposed by offering marine traffic supporting system which helps VTS operator assist vessel effectively with the quantitative assessment on difficulty of each vessel. The system collects navigation data from onboard AIS, assesses the data in assessment mode to analyze the navigation difficulties of each vessel and displays the degree of danger of each vessel on the ECDIS in real-time to decide the intervention time or order of priority for VTS operator. The effectiveness of the system was verified by the VTS operators in Korea.

In recently, IMO consider including an marine casualty factor when Port State Control Inspection evaluate.. This paper proposes an evaluation to Target Factor Values of Port State Control Inspections(PSCITFV) using absolute measurement. To this solve, therefore, this paper used the absolute measurement which is informed compensate the defect and the more rational and objective methode, checked the effectiveness to compare an result with absolute measurement and PSCITFV of Tokyo MOU using Wilcoxson test. Finally, rate change of PSC was investigated by an experiment which changed the values of evaluation factors. As a result, it was evaluation factors of high rate change that was detention, ship's age, casualty factors. Therefore, this factors have to a priority management to do for prevent of PSC.

Ship is being operated under a highly dynamic environments and many factors are related with ship's collision and those factors are interacting. So, an analysis on the ship's collision causes is very important to prepare countermeasures which will ensure the safe navigation. And the analysis confirmed that ship's collision is occurred most frequently and the cause is closely related with human factor. The main purpose of this study is to build a model of human factors in ship's collision cause using SD(System Dynamics} approach and to measure a effect which is risk control countermeasures of ship's collision. To achieve this aim, the structure analysis on the causes of ship's collision using FSM are performed, and the structure was changed by quantitative, qualitative factors and their feedback loops in casual map. This model was performed over 20 years(1993-2012) in a standard simulation model and 8 policy simulation models.

Ship is being operated under a highly dynamic environments and many factors are related with ship's collision and those factors are interacting. So, An analysis on the ship's collision muses is very important to prepare countermeasures which will ensure the safe navigation.

The main purpose of this study is to build a model of human factors in ship's collision muse using SD(System Dynamics} approach and to measure a effect which is risk control countermeasures of ship's collision.

Ship damage caused by maritime casualties leads to marine pollution and loss of life and property. To prevent serious damage from maritime casualties, several types of safety regulations are applied in ship design. Damage stability regulation is one of the most important safety issues. Designs of ships for long international voyages must comply with these regulations. Current regulations, however, do not consider the characteristics of the operating route of each ship and reflect only ship size and type of cargo. In this paper, a damage safety assessment was undertaken for a ship carrying radioactive waste in actual wave conditions. Damage cases for safety assessment were constructed on the basis of safety regulations and related research results. Hull form, internal arrangement, loading condition and damage condition were modeled for damage safety simulation. The safety simulation was performed and analyzed for 10 damage cases with various wave heights, frequency and angle of attack on an operating route. Based on evaluation results, a design alternative was generated, and it was also simulated. These results confirmed that damage safety analysis is highly important in the design stage in consideration of the operating route characteristics by simulation. Thus a ship designer can improve safety from damage in this manner.

The marine traffic congestion has increased due to the expansion of vessel traffic volume in Korean coastal waterway these days. Heavy traffic could bring serious marine casualties which cause the loss of human lives, properties and marine pollution in coastal area. In this paper, the probability analysis of marine casualties in Korean coast. To achieve this aim, clears up the cause of accident and examines closely the mutual relations among marine casualties, weather condition, and marine traffic volume. These casualties are classified into several patterns or the point of view of ship's size, ship's type and ship's age and its characteristics of each pattern are described In detail.

It is very important for ability to be treated to protect and secure the loss of life and property in emergency situation at sea. 80% of maritime casualty are incurred by human factors rather than a mechanical reason, which means that most maritime incident does not come from only one factor by mistake, but multiple potential factors causing a fault and error. Therefore, after research of the leadership effect to the ship, decision making process and behavior characteristics occurred in emergency situation, this paper presents settlement scheme and strategy in order to reduce human error in the ship.
