The coastal composite fishery has the highest rate of around 30.0% in registered fishing vessels of Korea for the last three years. The risk analysis for the fisher's safety of coastal composite fishing vessels was conducted to serve as a basic data for improving the healthy and safe working environment of fisher using fisher's occupational accidents of the national federation of fisheries cooperatives (NFFC) from 2016 to 2018 (n = 1,105). As a result, the occupational accident occurrence rate of coastal composite fishery was 3.76% in all industries, 7.8 times the rate of that. In addition, death and missing rate was found to have a serious level management to 10.10‱. Among the accidents, 76.0% occurred at sea. The slipping, others and contact with machinery or fishing gear occurred more frequently in order in the frequency of accident occurrence pattern. In the risk assessment using frequency and severity, slipping, contact with machinery and others showed high risk during fishing. The results are expected to contribute to identification and assessment of safety hazard occurred in coastal composite fishing vessels.

This study analyzed the condition of marine accident and disaster rate of crew of Korean fishing vessels by vessel type, and checked the Australian safety management system and relevant regulation in Korea to suggest measures to build coastal/offshore fishing vessel safety management system in Korean coastal/offshore fishery. As a result, the power and production amount of Korean coastal/offshore fishing vessel is consistently decreasing while marine accident is increasing. Disaster rate of crew was higher than land industry, especially, the disaster rate of coastal/offshore fishing vessel was very high (100.0‰). Australia applies safety management system differed by vessel type and operation waters which fully considers the characteristics of pertinent vessel. The average accident rate of fishing vessels with gross tonnage over 20 tons among the Korean coastal/offshore fishing vessel was 13.6%, which was significantly higher than fishing vessels with gross tonnage below 20 tons (1.4%). Such result indicates it is urgent to implement safety management system to fishing vessel with gross tonnage over 20 tons and introduce fishing vessel safety supervisor. Establishing safety management system of coastal/offshore fishing vessel will contribute to consistent industrial development by achieving the general goal of reducing marine accident and spreading safety culture.

4차 산업혁명시대에 해운산업에서는 자율운항 선박의 출현이 예상되고 있다. 이와 관련된 충돌회피 시스템 연구는 활발하지만 대부분 상선을 중심으로 추진되고 있다. 자율운항 선박이 조우하게 될 모든 선박을 고려하였을 때 어선과의 충돌회피 시스템 연구 또한 반드시 필요하다. 본 연구에서는 어선의 점용면적(Ship's domain) 반영한 충돌회피 모델의 연구를 위하여 부산항과 인근 해역의 중·소형 어선과 모든 선박과의 통항 이격거리를 조사하였다. 통항량이 가장 많은 기간의 AIS 데이터 중에서 조우관계에 있는 어선과 모든 선박간 상대위치를 원형산포도로 나타내었고, 이를 대상선박으로부터 방위별 평균 이격거리 및 최다 통항 이격거리로 분석하였다. 분석 결과, 어선의 속력이 증가할수록 평균 이격거리는 방위별 4L에서 8L 정도로 증가하였고, 선박 길이가 증가할수록 10L 이상이던 평균 이격거리가 약 6L 정도로 감소하는 경향이 나타났다. 추후 어선의 점용면적 일반화를 통한 충돌회피 모델에 연구에 본 기초결과가 활용될 수 있을 것으로 기대된다.

The IMO has made constant efforts for global safety control of fishing vessels operation. As the result varieties of documents, for example, the international conventions, the resolutions, the recommendations and codes were adopted by the Organization. And the Organization contributed to preparing the international standards of marine safety by persuading the member countries to ratify and enforce the documents. The author inspected the content of IMO's activities and recent movement to ensure the safety of fishing vessels and their crew, and obtained the following results in connection with domestic regime. The first is the future prospect and countermeasure against revision and effectuation of "The Torremolinos International Convention for the Safety of Fishing Vessels, 1977". The Authority of Korean Government should make preparations to receive into national legislation as a performance of liability of a party country to the Convention. Secondly, the current domestic legal system has not any serious issues on the education and training for the fishing vessels crew. It is merely necessary to establish and operate the training course for the low grade marine officers.

The excessive cost of building ships causes the instability of payability, which manage poorly fishing vessels longer than 24m. As a result, an officer evades embarkation and a vicious circle is repeated. In this study, the optimal engine horsepower system for fishing vessels longer than 24m was invented to develop the most efficient engine horsepower, and also a database program for the most efficient engine horsepower has been developed based on the type of and their size.

The aim of this study is to reduce the foreign fishermen's rate of deserting from coastal and offshore fishing vessel in Korea and to suggest the future direction of foreign fishermen's employment policy. There are several employment systems for foreign fishermen who work on a coastal and offshore fishing vessels in Korea and Japan. Foreign fishermen's employment systems can be divided by the following forms : 1) Employment permit system for foreigners in Korea 2) Foreign seamen system in Korea 3) Skill training system for foreigners in Japan Foreign fishermen's rate of deserting from Korean fishing vessel is very high compared to that of Japan. The recent rate is 29.6% in employment permit system, and 21.5% in foreign seamen system in Korea. However, 2.2% in skill training system for foreigners in Japan. In this paper, the author investigated and compared the employment status of foreign seamen's in 2 country's fishing vessels and suggest to reduce the rate of deserting from workplace in Korean fishing vessels.

Marine fisheries resources face major anthropogenic threat from unregulated fishing activities; thus require precise detection for protection through marine surveillance. Korea developed an efficient land-based small fishing vessel monitoring system using real-time V-Pass data. However, those data directly do not provide information on fishing activities, thus further efforts are necessary to differentiate their activity status. In Korea, especially in Busan, longlining is practiced by many small fishing vessels to catch several types of fishes that need to be identified for proper monitoring. Therefore, in this study we have improved the existing fishing status classification method by applying Hidden Markov Model (HMM) on V-Pass data in order to further classify their fishing status into three groups, viz. non-fishing, longlining and other types of fishing. Data from 206 fishing vessels at Busan on 05 February, 2021 were used for this purpose. Two tiered HMM was applied that first differentiates non-fishing status from the fishing status, and finally classifies that fishing status into longlining and other types of fishing. Data from 193 and 13 ships were used as training and test datasets, respectively. Using this model 90.45% accuracy in classifying into fishing and non-fishing status and 88.23% overall accuracy in classifying all into three types of fishing statuses were achieved. Thus, this method is recommended for monitoring the activities of small fishing vessels equipped with V-Pass, especially for detecting longlining.

어선에서 선도나 경사시험자료가 없는 선박에서도 임의의 재하상태때 복원성요소 값을 얻을 수 있는 근사식을 구하기 위해 1980년에서 1983년 사이에 우리나라에서 건설된 어선 43척의 만재상태와 공하상태의 경사시험자료를 이용하여 각 선박의 평균흘수(dm)와 건현(f)의 비 값에 대한 KM/dm, KG/dm, KB/dm, GM/B의 값을 회로분석한 결과는 다음과 같다. 1. 어선별 복원성요소값은 어느 선형에서나 f/dm 값이 커질수록 KM/dm 및 KG/dm 값은 커지는 경향을 나타내었으며, KB/dm 및 GM/B의 값은 일정하게 변하였다. 2. KM/dm, KG/dm는 안강망어선, 기선저인망어선이 각각 가장 큰 경향을 나타내어 어업선의 종류에 따라 M과 G의 값이 다르게 됨을 알 수 있었다. 3. 업종별어선의 복원성요소값은 공하상태와 만재상태의 경사시험한 자료만으로서 정선적인 경사시험한 것과 같은 경향을 나타내고 있음을 확인할 수 있었다

The motion of small fishing vessels is significantly affected by small waves, leading to accidents, such as capsizing or sinking. This paper presents the results of two types of basin tests. The first test analyzed the characteristics of roll and pitch motions among regular waves with the same wave steepness using the drifting state of three (3G/T, 7G/T, 10G/T) small fishing vessels. The second test analyzed the motion characteristics of the 7G/T fishing vessel under different wave steepness. The first test showed that heave and roll motions are significant in the beam sea, while pitch motion is significant in the bow and stern seas. The second test shows that wave steepness has a linear relationship with roll and pitch motions in the bow and stern seas.
