At recently, Oil spill accident of large size oiler that happen domestic and outside the country is occured to social impact us as well as economical damage in sea environment. Also, because spread extent of pollution accident is reaching harbor, bay and close water areas, as necessity that traffic control ships are sea place. VTS is changing to concept that control space is magnified gradually. Our country is operated to 14 harbors which is control center. But abroad is operating coastal VTS that do main waterway and coastals to authority dimension. Therefore, necessity that traffic density of ship manages high coastals and ship traffic of waterway to our country is risen. This paper is execute sea traffic survey at Mokop sea areas and sea casualty occurs. It proposal that coastal VTS center field of most suitable and position of radar site.

It is unsafe to attempt a complete definition of the expression 'perils of the seas', because in practice the question 'what is a peril of the seas' is inextricably woven up with the further question, 'was the loss proximately caused by the sea peril ?' Such casualties as stranding, collision and heavy weather appear with monotonous regularity in the daily reports, and are the obvious examples. However, what can be included in the term 'perils of the seas' seems to be inexhaustible, although most circumstances appear to have been covered by the Courts. Two cases heard in 1887 were instrumental in defining perils of the seas. In The Xantho Lord Herschell made the following remarks: "The term ... does not cover every accidents or casualty which may happen to the subject matter of insurance on the sea. It must be a peril 'of' the sea. Not every loss or damage of which the sea is the immediate cause is covered by these words. They do not protect, for example, against that natural and inevitable action of the winds and waves which results in what may be described as wear and tear. There must be some casualty, something which could not be foreseen as one of the necessary incidents of the adventure. The purpose of the policy is to secure an indemnity against accidents which may happen, not against events which must happen. ... If a vessel strikes upon a sunken rock in fair weather and sinks, this is a loss by perils of the sea."

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.

Naval ships could be seriously damaged by enemy attacks in battle. Moreover, this damage could be spread and deteriorated into a secondary accident. Secondary accidents that have adverse effects on naval ship's survivability, such as fire, flood, smoke extension, and patient occurrence, are defined as casualties. These casualties sharply degrade the survivability of naval ships. Furthermore, naval ships could be burned-out and sunk by casualties in isolated sea. Therefore, damage control and rapid suppression of the casualties in the naval ships is essential. This study was conducted in the establishment of suppression paths according to the characteristics of each casualty so that the developed system can support the rapid suppression in an emergency and even the training situation on a regular state. To establish the suppression paths, the two-dimensional numerical map is designed by converting the three-dimensional features of the naval ships, and the well known algorithms are compared to present the appropriate one for path finding problem on the naval ships. Finally, we devised a specific routing algorithm that fits the characteristics of each casualty in accordance with the Korean Navy's doctrines and handbooks of casualty suppression.

The amount of Sea Casualty is increased by heavy sea traffic, increasing sea-borne cargoes, and superannuated vessels. This study analyzed the circumstance of ship salvage in Korean Salvage Units and management of Salvage Divers in Korea and other countries in order to make establishment of Ship Salvage Divers. This paper reputed the object, the necessity and the character of Ship Salvage Divers. For the purpose of study two parts are considered in order to analyze the environment of salvage divers(the circumstance of Sea Casulties and Ship Salvage). Under the present circumstance in Korea this development planning study may be restricted, but the effective planning to activate Korean Ship Salvage Diver is abstracted as follows; First, the political assistance of concerned government authority is needed. Second, establishment of new course, grade, certificate and licence for Salvage Diver is a Pre-requisite factor for the successful enactment. Third, establishment of Korean Ship Salvage Diving Center or School is strongly required.

The ship's signal sound dispersed by air, obstacles, and noises due to absorption, reflection, and disturbances, respectively. It is one of the factors of marine casualties by misjudgment if receiving direction The last target of this study is to prevent inherent marine casualty using the analysis-evaluation techniques if the interferences of ship's signal sound. In this work, three-dimensional sound field control model is proposed to simulate various sound transmitting characteristics according to sea environments at sea The efficiency test of the model was carried out using VR-based ship simulator.

A party to the charter will not be able to rely upon the doctrine of frustration if an event which makes further performance impossible has been caused by his breach of the charter. Strictly speaking, this is not a situation of frustration at all but rather a case of discharge of the contract by breach. In the Sea Angel case, the defendant entered into a Lloyd's Standard Form of Salvage Agreement with owners of the casualty on the LOF 2000 form, incorporating the SCOPIC clause. The time charter was on the terms of the Shelltime 4 form. This case the trial of the action brought by the claimants owners of the vessel Sea Angel claiming outstanding hire from the defendant charterers. This Case was issued whether charterparty frustrated by refusal of port authorities to issue "No Demand Certificate" allowing port clearance pending payment of oil spillage clean-up costs. The court concluded that no attempt had yet been made to invoke the assistance of the Pakistani court to obtain the release of the vessel. There was not so radical or fundamental a change in the obligation assumed by defendant as to establish frustration. The purpose of this study aims to analyse frustration and time charter in the Sea Angel case.

A tragic disaster happened by capsizing O-Ryong 501 trawler at Western Bering Sea in 1st, Dec. 2014. The disaster was caused by the severe weather and the long deferred escape from the storm in fully developed high sea. Lots of sea water from poop deck rushed into the fish ponder with fishes all together after hauling net and then remove the fishes from codend. The vessel became to incline to the one side caused by the weight and the free surface effect of flood sea waters and fishes at initial stage. In spite of crews all effort to discharge the waters, but the work was not achieved successfully. For the worse thing, the order of abandon ship was issued too late. After all, the ship capsized and sank, then almost crews became to the victims of the casualty including captain. In this paper, author carried out restrictively the calculation of dynamic factors influenced on the disaster including the weather condition and effects of the flood sea waters, and found out that the most important causes of the disaster were the decrease of stabilities, GM was decreased from 0.9m to 0.08 m, and the high waves which led to the vessel disaster.
