Sunken vessels accidents have harmful impacts on the marine environment because of oils and chemicals in the vessels. The government has managed them and developed risk assessment which can evaluate potential risk quantitatively since 1999. But the grades of present risk assessment has changed greatly depending on quantity of remaining fuel oils, and the list of remaining fuel oils omitted in status report of sunken vessels. Therefore, the aim of the study is to estimate and develop model for quantity of remaining fuel oils and verify the remaining fuel estimation comparison with active vessels. To accomplish the purpose of the study, apply this verified estimation model to current risk assessment and recommend guideline for an accurate sunken vessels risk assessment.

Marine risk assessment considers events such as collision/grounding, sinking/capsize, fire/explosion and flooding, developing relationships between their causes and effects. In addition, risk assessment of previously sunken ships are also necessary since they continuously have possibility for further oil spill or can cause other marine accidents. The objective of this paper is to develop the risk assessment systems for sunken ships to prevent oil spill and further marine causalities in order to preserve safe and clean oceans around Korea peninsula. The risk assessment systems for sunken ships comprise of database management sub-system for sunken ships, qualitative risk assessment sub-system, quantitative risk assessment sub-system, and cost-benefit analysis subsystem.

This paper was provided to apply the ITC-Hulls Clauses & ISM Code for the accident of sunken ship which was occurred by seamen's barratry. For the causes of the sunken accident, the underwriter insisted toot shipowner submerged the vessel intentionally for the purpose of the insured amounts, while shipowner protests toot the ship was submerged because of crews faults. In this connection, the judge sentenced toot this accident was caused by humans errors as the Provisions of 6.2.4 of ITC-Hulls, however shipowner is responsible for hiring onboard qualified seafarers and carrying out the due diligence for performing ISM Code for ensuring ship's safety and seaworthiness.

해상에 설치된 등부표에 등화를 밝히기 위해서는 전력 생산장비와 전력 저장장치가 필요로 하는데 등대 및 등부표에 사용하는 등명기는 현재 태양전지와 축전지 및 광원인 등명기를 각기 별도 설치하여 운영하여 등대 관리에 많은 시간과 예산이 소요되는 단점이 있어 국제적으로 전원일체형 등명기를 사용하는 추세이다. 재생에너지를 이용해 안정적인 전원을 공급받으며, 연안 수역을 운항하는 선박이 항로표지를 쉽게 식별할 수 있고, 해양사고 발생 시 긴급 수색 및 구조시스템 외에 침몰선박의 위치를 알려주는 기술을 연구 개발하였다.

Our ocean where three sides are the seas is the state that the environmental pollution damage is serious because of all kinds of wastes. Therefore, environmental pollution will be considerably decreased if we leans forward in the saddle to manage net which is conquering a section equivalent among wastes and will be helpful to marine ecosystem. This study is to develop a fishing net management system identifying nets cast and withdrawn from the vessel The purpose of FNMS is to manage sailing vessels arrival and departure details in order to manage a net abandoned in the ocean, and restrain the occurrence of the wasted net abandoned without permission in the ocean, and prevent environmental pollution and sailing vessels sank in and around the ocean.

The sinking of the M/V SEWOL in April 2014 was not a mere marine accident, but a marine catastrophe. This grim case developed into a social tragedy that impinged the national sentiment and communal integrity. It is imperative that thorough provisions and measures be outlined at the national level with regard to massive marine accidents, oil pollution, and natural disasters that might critically affect government affairs. Pivoting on "The Black Swan Theory," a concept of improperly rationalizing a national crisis based on uncertainties, this research assesses a variety of response strategies that minimize the national economic and social damage caused by a large-scale marine disaster. Along with the effort of minimizing any potential defects in each protective barrier, the "Black Swan Detection System of the Marine Disaster" needs to be incorporated to prevent cases wherein such defects lead to an actual crisis. Maritime safety must be systematically unified under a supervisory organization, and a structure for maritime crisis on-scene command and cooperation must likewise be established in order that every force on the scene of a marine disaster may act effectively and consistently under the direction of an on-scene commander.

The purpose of this study is to introduce United States Coast Guard (USCG) in order to suggest a direction to advance the system of Korea Coast Guard. After the effect of United Nations on the Law of the Sea in 1994, the world is facing with new era of maritime age with emergence of new maritime border 'Exclusive Economic Zone(EEZ)'. Along with new maritime era, Korea also has been facing with the conflicts caused from EEZ. Also, there is a increasing concern about maritime safety and security since people looking for maritime tourism and leisure sports are dramatically increasing in Korea. Moreover, national security matters are a big issue in Korea due to the several incidents occurred in the sea such as the attack on Yeon-Pyung Island and the sinking of Cheonan naval vessel. Arising concern on these issues in maritime space requires Korea Coast Guard to handle these effectively. However, the systematical and structural limitation of Korea Coast Guard limits the effective management of recent issues. The United States Coast Guard which is considered as one of the military force in the United States has continuously reformed and developed its system and structure to better handle the maritime safety and security issues through developing project such as the Integrated Deep Water system. Also, maritime police system and structure in the United States is different with in Korea. This study expects to suggest a way to advance the system and structure of Korea Coast Guard through examination of United States Coast Guard and comparing maritime police system and structure between Korea and the United States in order to properly deal with the maritime safety and security issues arising recently.
