The marine safety investigation inquires and concludes the facts and causes of the marine casualties and incidents with the objective of preventing similar roses in the future. Thus, IMO and most states adopt and revise marine safety related conventions and national laws based on the results of marine safety investigation. In particular, IMO recently adopts mandatory IMO Casualty Investigation Code to identify the precise cause of rose with states' cooperation, to report the result of investigation, and to establish new international safety standard helping prevention of similar cases based on the report. The Judgement of the Korean Maritime Safety Tribunal system based on the 'Act on the investigation of and inquiry into marine accidents' is used for the purpose of marine safety investigation in Korea to prove cause of marine accident and to improve marine safety. Therefore, this study examines the Code and compares the Code with the Act to reflect the contents of provisions in the Code into the Act. The study would also be the basic references in relation to revising of marine safety investigation system in Korea Specially, the contents in relation to the independence of investigation authority and mandatory counselling system, and guarantee of seafarers human rights to ensure fairness of investigation would be included.

In the shipping industry, it is well known that around 80 % or more of all marine accidents are caused fully or at least in part by human error. In this regard, the International Maritime Organization (IMO) stated that the study of human factors would be important for improving maritime safety. Consequently, the IMO adopted the Casualty Investigation Code, including guidelines to assist investigators in the implementation of the Code, to prevent similar accidents occurring again in the future. In this paper, a process of the human factors investigation is proposed to provide investigators with a guide for determining the occurrence sequence of marine accidents, to identify and classify human error-inducing underlying factors, and to develop safety actions that can manage the risk of marine accidents. Also, an application of these investigation procedures to a collision accident is provided as a case study This is done to verify the applicability of the proposed human factors investigation procedures. The proposed human factors investigation process provides a systematic approach and consists of 3 steps: 'Step 1: collect data & determine occurrence sequence' using the SHEL model and the cognitive process model; 'Step 2: identify and classify underlying human factors' using the Maritime-Human Factor Analysis and Classification System (M-HFACS) model; and 'Step 3: develop safety actions,' using the causal chains. The case study shows that the proposed human factors investigation process is capable of identifying the underlying factors and indeveloping safety actions to prevent similar accidents from occurring.

Recently, fatigue related to marine accidents was recognized to be very important contribution factor when marine accidents such as collision, aground, fire, etc. were investigated Many studies concerned about fatigue factors related to human error can be found. In this study, the analysis and examination of USCG Fatigue Investigation Program were carried out in order to investigate marine accidents happened in Korean waters. The Fatigue Investigation Program was established on the MAIFA(Marine Accident Investigators Forum in Asia) web site. Finally, the application plan of the program was discussed.

The purpose of Maritime Safety Tribunal is that experts about ship operation investigate and reveal causes of marine disasters and suggest plans to prevent recurrence in Korean Maritime Safety Tribunal which is a kind of administrative court. Despite the fact that 72% of marine disasters is fishing vessel accidents and 75% of collision accidents between vessels which most occur is related to fishing boats, it is the very serious problem that there is no any person with licenses of marine technicians for fishing vessels in judges and investigators of Korean Maritime Safety Tribunal. The operational characteristics of fishing vessels, their sizes, and shift patterns of duties in wheelhouses are completely and incommensurably different from those of merchant vessels. By the way, if the investigators and judges who just consist of merchant vessel experts investigate and judge marine accidents about fishing vessels, there could be errors in establishment of policies to investigate and reveal their causes and prevent recurrence of accidents. Especially, in case of collision accidents between fishing vessels and merchant vessels, it is thought that the marine accident interested provides causes which can be doubtful about fairness of judges. Therefore, it is thought that the ratio of judges and investigators is most desirable to compose it to be similar to the occurrence frequency of marine accidents. For this, the following solution plans are suggested. First, qualification for appointment requires first class marine technicians. But there is the only one vessel which needs the first class in fishing vessels. Therefore, it is thought that the provisory clause should be added so that the second class marine technicians can be used instead of the first class ones. Second, the marine accidents of fishing vessels reach 72% but the fact that there is no any judge and investigator with licenses of marine technicians for fishing vessels is thought to go against the purpose of establishment of Korean Maritime Safety Tribunal. Therefore, it is thought that there is, at least, one more judges and investigators in the central and local Korean Maritime Safety Tribunals. The same method should be applied to judge assistants and investigation assistants.

In the present paper, the analysis is on the safe navigation between ships moving each other in restricted waterways under the external force, such as wind or current The numerical simulation of manoeuvring motion was carried out to propose an appropriate safe speed and distance between ships, which is required to avoid marine disasters from the viewpoint of marine safety. From the inspection q this investigation, it indicates the following result In case of proximal navigation between ships under the wind and current, the low-speed vessel is potentially hazardous because the rudder force if low-speed vessel needed for steady-state course-keeping is not sufficient, compared to the high-speed vessel The manoeuvring characteristic based on this investigation will be very useful for keeping the safety of navigation from the practical point of ships design and traffic control in restricted waterways.

Saigon-Vungtau fairway is the main and the most important fairway of the major economic areas: Ho Chi Minh City, Dong Nai Province and Ba Ria-Vung Tau Province in Vietnam. In last 5 years, 80% of accidents happened on the fairway were caused by collision and contact/impact. This presentation study on marine traffic investigation in the adjacent of the fairway to find out problems related to marine traffic for improving Marine Traffic Safety Management in this area.

The marine accident investigation of Korea Marine Safety Tribunal does not keep up with the international rule and guideline. Also there is no proper investigation manual. This study analyzed the investigation system and manual of Korea. USA and Japan etc., and proposed the newly investigation system and manual of KMST including the classfication guideline of marine accident investigation and analysis.

This paper reviews the analysis of a given scenario according to the Hybrid Model, and why accident causation models are necessary in casualty investigations. The given scenario has been analyzed according to the Hybrid Model using its main five components, fallible decisions, line management, psychological precursors to unsafe acts, unsafe acts, and inadequate defenses. In addition, the differences between the SHEL and the Hybrid Model, and the importance of a safety barrier during an accident investigation, are shown in this paper. One unit of SHEL can be linked with another unit of SHEL. However, it cannot be used for the analysis of an accident. Therefore, we must use an accident causation model, which can be a Hybrid Model. This can explain the "How" and "Why" of accident, so it is a suitable model for analyzing them. During an accident investigation, the reason we focus on a safety barrier is to create another safety barrier or to change an existing safety barrier if that barrier fails. Hence, the paper shows how a sea accident can be investigated, and we propose a preventive way of avoiding the accident through combining the methods of different models for the future.
