Marine casualties of dangerous cargo carriers lead to not only the loss of human life and properties, but also marine pollution caused by spilled oil and hazardous cargo. So the prevention of marine casualties and emergence response to minimize pollution are very important problems to be settled. But until now, most of salvage assistance jobs have been done based on rule of thumb without any technical support. It is not easy to cope with the incidents safely and rapidly under the current situation. The purpose of this paper is to develop a systematic and engineering salvage assistance tool available in the casualty sites. This paper contains the construction of salvage system, classification of technical items, and prototype system for the safety assessment. The developed system enable a salvage engineer in his/her salvaging jobs to perform safely and promptly.

In 2010 Manila Conference, the revised STCW (International Convention on Standards of Training, Certification and Watch-keeping for Seafarers) of IMO recalled that a large percentage of maritime casualties and pollution incidents are caused by human error. Therefore, education and training improvement will play important role to reduce maritime casualties. From this, we focus on improving safety during sailing through upgrading the education and training for Korean cadets by updating maritime education and training program. In terms of a maritime education program from some of the maritime universities in the world such as United States Merchant Maritime Academy(USMMA) Philippine Merchant Marine Academy(PMMA), are compared to the Maritime University in Korea. As a result, we suggest an effective education system.

Due to a recent increase in maritime activities in South Korea, the frequency of maritime distress is escalating and poses a significant threat to lives and property. The aim of this study was to validate a drift trajectory prediction technique to help mitigate the damages caused by maritime distress incidents. In this study, OpenDrift was verified using satellite drifter data from the Korea Hydrographic and Oceanographic Agency. OpenDrift is a Monte-Carlo-based Lagrangian trajectory modeling framework that allows for considering leeway, an important factor in predicting the movement of floating marine objects. The simulation results showed no significant differences in the performance of drift trajectory prediction when considering leeway using four evaluation methods (normalized cumulative Lagrangian separation, root mean squared error, mean absolute error, and Euclidean distance). However, leeway improved the performance in an analysis of location prediction conformance for maritime search and rescue operations. Therefore, the findings of this study suggest that it is important to consider leeway in drift trajectory prediction for effective maritime search and rescue operations. The results could help with future research on drift trajectory prediction of various floating objects, including marine debris, satellite drifters, and sea ice.

The global surge in maritime traffic has resulted in an increased number of ship collisions, leading to significant economic, environmental, physical, and human damage. The causes of these maritime accidents are multifaceted, often arising from a combination of crew judgment errors, negligence, complexity of navigation routes, weather conditions, and technical deficiencies in the vessels. Given the intricate nuances and contextual information inherent in each incident, a methodology capable of deeply understanding the semantics and context of sentences is imperative. Accordingly, this study utilized the SentenceBERT model to analyze maritime safety tribunal decisions over the last 20 years in the Busan Sea area, which encapsulated data on ship collision incidents. The analysis revealed important keywords potentially responsible for these incidents. Cluster analysis based on the frequency of specific keyword appearances was conducted and visualized. This information can serve as foundational data for the preemptive identification of accident causes and the development of strategies for collision prevention and response.

In the case of occurring marine oil pollution, it is the most effective way that to prepare all the necessary response resources in advance and to respond to incidents, but there are limits in reality. Therefore, may be an important alternative ways to use a fishing vessel registered in the affected area by massive marine oil pollution efficiently. In the United States and other developed countries, it is can be found that temporary response program by local fishing vessels(VOO program) has been developed and operated. This study was examined for sweeping arm system suitable for domestic small fishing vessels. The selected small vessel was as the model of Coastal gill-net and compound fishing vessel with classes of 2.5~3.5tons, length 8~9m, breath 2.5~2.8m, horsepower 200~250 HP and FRP materials. The developed equipment was designed that can be easily mounted on the model ship and portable structure. For increasing the field practicality, the weight of each part was composed less than 10kg for easy assembly and disassembly.

Recently, the interest in marine leisure activities has been growing rapidly with the work-life balance trend. In response to this demand, the Korean government is supporting fostering and revitalizing the relevant industries and facilities. In particular, a marina has been making efforts to change itself into a resort with multiple amenities instead of a simple mooring facility. However, the facilities in a marina for the transport of marine leisure equipment mostly consist of cranes and boat-lifts using ropes, which can result in incidents such as damage and accidents during lifting or movement. This paper proposes the equipment and support system for the safe transportation of marine leisure ships. Aluminum transport equipment was designed by performing a structural analysis to achieve a lighter weight than the existing steel products. In addition, a safety support system with alarms for tilting or obstacles and a slope monitoring system was developed to enhance the safety during operation and transportation. The safety support system developed in this study was implemented and installed in the transport system, and verified through commissioning on land.

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.

Due to limitations in responding to oil spill incidents that are urgent or that cover a wide area with only oil spill response vessels, Korea Coast Guard (KCG) patrol vessels are utilized. In this study, we have developed an oil sweep system suitable for small patrol vessels. The equipment consists of three components - fixed support, poles, and slide fixers - and can be fastened with a toggle pin to a fall prevention bar on small patrol vessels without welding or additional efforts for installation. The respective weights of each component - fixed support, poles (2 pcs), and slide fixers (4 pcs) - are approximately 9.2 kg, 6.5 kg, and 3.5 kg. The 3 m-pole, which is rotatable 180 degrees horizontally, is folded deckward when replacing oil absorbents. As the development of this equipment has improved the method of deploying and retrieving oil absorbents on KCG small patrol vessels, we expect that more efficient oil spill cleanup will be possible.

In Korea for 20 years(1993-2012), total number and average annual number of oil spills were 6,608 cases and total volume and average annual volume of oils spilt were $57,328k{\ell}$ and nearly $2,866k{\ell}/year$, respectively. The annual number of oil spills and annual amount of oil spilt tended to decrease with the lapse of year in Korea. As oil transportation worldwide continues to increase, many communities are at risk of oil spill disasters and must anticipate and prepare for them. Factors that influence oil spill consequences are myriad and rage from the biophysical to the social. In this paper, we analysed the emergency response systems and recovery apparatuses for oil spill accident in marine and proposed a developed oil diffusion apparatus which can be used to initial response stage by crew, and to extend golden times. This system can be minimized casualties for rescued people in disaster.
