특정 선박의 조종성능이 실질적으로 제한되어 있는지 여부는, 특정한 선박을 기준으로 해당 선박의 기능적 특성과 운항 당시의 환경을 종합적으로 고려하여 판단하여야 하는 상대적 개념이다. 어로에 종사하고 있음으로 인해 조종성능이 실질적으로 제한되어 있는지 여부를 다른 선박이 명확히 판단하는 것은 용이하 지 않다. 따라서 해상교통안전법 제83조의 적용에 있어서는 특정 선박이 자신 의 항법상 지위를 정확히 판단한 후 이에 부합하는 등화 및 형상물을 표시하는 것이 무엇보다 중요하다. 다수의 재결에서 해양안전심판원은 통발조업 어선의 법적 지위를 어로에 종사하고 있는 선박으로 인정한 사례가 있지만, 일부 재결에서는 이에 반대되는 사례도 있다. 그러나 위와 같은 해양안전심판원의 재결 은 개별 사안에서 구체적 타당성을 고려한 심판원의 고민의 결과라고 해석하는 것이 타당하다. 어업실무상 통발조업에 사용되는 통발의 종류는 다양할 뿐만 아니라 규격화되어 있지 않다는 점과 통발을 사용하여 어획하는 어류도 다양하 다는 점을 고려하면, 유사한 성능을 가진 선박이 유사한 환경에서 통발조업을 하더라도 해당 선박의 항법상 지위에 관해 항상 동일한 결론이 도출된다고 보 기는 어렵다. 해양안전심판원은 일부 재결을 통해, 어로에 종사하고 있는 선박 의 판단기준으로서 사고 당시 선박의 침로나 속력의 변경 가능성 외에 적극적 인 피항동작으로 인한 어구 등의 손상 가능성을 고려하고 있다. 그렇다면 통발 조업 어선의 어로에 종사하고 있는 선박으로서의 지위에 관해서는 향후 심판원 의 재결을 통해 해당 문제에 대한 명확한 입장 표명이 요구된다.

Although it is highly dependent on the production of coastal and offshore fishing, the Fishing Vessels Safety Fisheries Act was enacted in 2019 due to the continuous increase in marine accidents of coastal and offshore fishing vessels. However, the law is too focused on fishing and navigation in certain waters and does not contain accident-preventive content. Ministry of Oceans and Fisheries proposes a plan to revise the Fishing Boat Safety Fishing Act through legal comparison with Japan's Seafarers' Labor Sanitation Rules. It also proposes an amendment that includes the content of the Seafarers Act on post-accident action obligations. Under the Fishing Vessels Safety Fishing Act, the safety fishing education is implemented for specific people and adopts a method of delivery education after completing the education. The reason for this is that the educational requirements are not sufficient compared to the number of education personnel. Moreover, four hours of education are conducted once a year, which is not suitable for insufficient educational conditions. For efficient safety fishing education, improvement measures are proposed compared to education in the United States and the United Kingdom.

This paper is the result of a comparative analysis of crew members' workloads using the EMG and OWAS methods according to the fishing process before and after the improvement of the operating system of the experimental vessel, with the aim of improving operational efficiency and safety work of coastal improved stow net fishing vessels. The target crew members were three people with at least five years of experience on board the same fishing vessel as the experimental vessel. After improving the operating system, such as installing a power block crane and two capstans, change the location of the ball-roller, the time required for setting and hauling work decreased (p < .01), and the evaluation results by OWAS showed that the overall workload for setting and hauling net work decreased. The results of muscle activity analysis showed a decrease in lashing anchor work (p < .01) in the case of hauling net and in anchor dropping work in the case of setting net (p < .001). It is judged that the use of ball rollers in net handling has been reduced; consequently, work safety has been improved.

This study analyzed the allocation of the skipper’s attention during fishing operation in the wheelhouse of a Korean coastal composite fishing vessel by using video observation. To summarize the results, the ratio of lookout, radar and GPS monitoring, which is essential for prevention of collision at sea, was significantly lower than that of other fishing operation due to the attention concentration on the work place during hauling line. In order to reduce exposure to risk of collisions due to concentration of attention to certain tasks such as line hauling, it is necessary to develop an alert system that can notify the approach of other ships or obstruction throughout the ship using information from radar or the automatic identification system. In addition, the order of attention allocation to devices and facilities obtained in this study is expected to be used as basic data for device or facility layout based on the principle of usage frequency in designing wheelhouse for coastal composite fishing vessels in the future.

연안통발 어민에 대한 설문조사 결과, 통발 투하 및 인양 중 로프 걸림에 따른 전도사고가 42.1 %로 가장 높았고, 갑판에서 미 끄러짐과 통발 권양장치의 신체 협착사고가 각각 21.1 %를 차지하였다. 또한 가장 위험한 작업은 전체 조사대상의 53.2 %가 통발 인양과 정을 들었고, 어종선별 33.8 %, 통발 투하 9.1 % 순으로 응답하였다. 어민들은 통발 권양장치의 주요 개선 요구사항으로 응답자의 36.8 %와 31.6 %가 통발을 수중에서 작업갑판까지 수월하게 인양하는 방안과 통발 인양 시 로프 장력 극복과 슬립 방지 등 사고저감 방안을 언급하 였다. 본 연구에서 소형 통발어선 권양장치는 구동롤러와 로프 간의 적정한 접촉각을 통해 로프의 접촉면적과 마찰계수를 증가시킴으로 써 권양력을 높이는 것이다. 구동롤러와 로프 간의 접촉각이 1°, 5°, 9°, 14° 및 19°일 때 로프 장력은 각각의 접촉각에 따라 차이를 보였으 며, 9°일 때 가장 높은 392.62 kgf까지 측정되었다. 이러한 실험결과를 반영하여 시제품 권양장치를 제작하고 총 길이가 100 m인 로프에 4 m 간격으로 총 25개의 통발을 해상에 설치한 후 인양에 따른 로프 장력을 측정하였다. 그 결과, 로프 장력은 통발 인양작업 초기에 급격히 증가하여 가장 높은 31.89 kgf로 측정되었으며, 이후에는 크게 낮아졌다. 따라서 소형 통발어선 권양장치의 권양력은 인양작업 초기에 부 여되는 최대 로프 장력 값을 기준으로 설계하는 것이 타당하다.

The fishery compensation by marine spatial planning such as routeing of ships and offshore wind farms is required objective data on whether fishing vessels are engaged in a target area. There has still been no research that calculated the number of fishing operation days scientifically. This study proposes a novel method for calculating the number of fishing operation days using the fishing trajectory data when investigating fishery compensation in marine spatial planning areas. It was calculated by multiplying the average reporting interval of trajectory data, the number of collected data, the status weighting factor, and the weighting factor for fishery compensation according to the location of each fishing vessel. In particular, the number of fishing operation days for the compensation of driftnet fishery was considered the daily average number of large vessels from the port and the fishery loss hours for avoiding collisions with them. The target area for applying the proposed method is the routeing area of ships of Jeju outer port. The yearly average fishing operation days were calculated from three years of data from 2017 to 2019. As a result of the study, the yearly average fishing operation days for the compensation of each fishing village fraternity varied from 0.0 to 39.0 days. The proposed method can be used for fishery compensation as an objective indicator in various marine spatial planning areas.

In order to understand basic data for improving the fishing system and fishing vessel structure in coastal improved stow net fishery, a questionnaire survey and on-site hearing were conducted from May 10 to June 11, 2019 to analyze opinions on the improvement of operation status and fishing vessel structure. The questionnaire survey consisted of ten questions on the operation status of coastal improved stow net fishery and six questions on the improvement of fishing vessel structure, and the results of each question were analyzed by the region, the captain’s age, the captain’s career and the age of fishing vessel. As a result of analyzing opinions on the operation status of the coastal improved stow net fishery, it was found that the average time required for casting net was 32.8 to 33.0 minutes and that the average time required for hauling net was 41.0 to 42.2 minutes which took 10 to 12 minutes more than for casting net. The most important work requiring improvement during fishing operation (the first priority) were ‘hauling net operation,’ ‘readjustment and storage of fishing gear,’ and ‘fish handling’ and the hardest factor in fishing management were in the order of ‘reduction of catch,’ ‘labor shortage’ and ‘rising labor costs.’ The most institutional improvement that is most needed in coastal improved stow net fishery was an ‘using fine mesh nets.’ Most of the respondent to the questions on the experience in hiring foreign crews was ‘either hiring or willing to hire foreign crews,’ and the average number of foreign crews employed was found to be 2.3 to 2.4 persons. The most important reason for hiring (or considering employment) foreign crews was ‘high labor costs.’ The degree of communication with foreign crews during fishing operation were ‘moderate’ or ‘difficult to direct work.’ The most important problem in hiring foreign crews (the first priority) was an ‘illegal departure.’ As the survey results on the opinion of structural improvement of coastal improved stow net fishing vessel, the degree of satisfaction with fishing vessel structure related to fishing operation was found to be somewhat unsatisfactory, with an average of 3.3 points on a five-point scale. The inconvenient structure of fishing vessel in possession (the first priority), the space needed most for the construction of new fishing vessel (the first priority) and the space considered important for the construction of new fishing vessel (the first prioprity) was a ‘fish warehouse.’ The most preferred equipment for the construction of new fishing vessel were ‘engine operation monitoring’ and ‘navigation safety devices.’ The average size (tonnage class), the average horse power and the average total length of fishing vessel for proper profit and safety fishing operation was between 13.8 and 14.0 tonnes, 808.3 to 819.5 H.P. and 23.4 to 23.5 meters, respectively. The results of the operation status of coastal improved stow net fishery and the requirement for improving the fishing vessel structure are expected to be provided as basic data for reference when we build or improve the fishing vessel.

The research was analyzed the catch data of the five years (2016-2020) for six joint venture company tuna purse seiners in the Atlantic Ocean, with the aim of suggesting improvement measures for responsible and sustainable fishing according to changes of recommendation by International Commission for the Conservation of Atlantic Tuna (ICCAT) on the tropical tunas. In the last five years, the average catch of six tuna purse seiner gradually increased to 7,745 tons, 8,364 tons and 9,053 tons from 2016 to 2018, but decreased to 7,761 tons in 2019 and 6,214 tons in 2020. The reason for the decrease in fishing volume in 2019 and 2020 was the fluctuation of the formation of the cold water zone (22-23℃), and the total ICCAT convention area of FAD closure in January and February due to the expansion of the FAD closure area and poor free school catching during two months period, respectively. The analysis on fishing area showed that the percentage of fishing in the high sea was about 85% although the FAD closure area included the EEZ zone in coastal countries; the rise of the fishing license in coastal countries is also believed to be a factor. In order to overcome such situations and improve catching volume, it will be possible if excellent manpower is secured, school fishing is expanded, and the production of high value-added catch (purse seine special: PS).

Recently, the annual emission rate of CO2 that is the main reason for domestic greenhouse gases is the third highest globally, which means it is an extremely serious issue. It is considered that these greenhouse gases affect climate changes. Especially, the emissions of CO2 in the fishing industry are nearly 4.11 million tons each year, occupying 0.7 percent of domestic total emissions. Therefore, this study clearly analyzed fuel consumption of major fish species over the recent five years focusing on large purse seines. It was revealed that mackerels occupied 55.7 percent of total fish catches of large purse seines and 57.5percent of total fishing earnings. Also, fuel consumption was 236.62 liters per ton caught and 179.51liters per million won earned.

Stow net fishery is one of the fishery with high fishing work accidents in southwestern sea of Korea. We conducted to serve as basic data for improving the healthy and safe working environment of fisher using risk assessment process (ISO45001) with fishermen’s occupational accidents of the National Federation of Fisheries Cooperative (NFFC) from 2016 to 2018. The average occurrence rate of victim in this fishery was 9.04%, 16.7 times more than such rate in all industries. In addition, the average fatality rate was found to have a very serious level management to 31.06‱, 27.7 times more than such rate in all industries. The safety hazards of stow net fishery was more likely to occur by other general industrial groups, with more severe consequences after the accident. According to 4M analysis, 58.6% of all accidents were caused by human factors, 24.0% by environmental factors, 16.0% by mechanical factors, and 1.5% by managerial factors, respectively. The occurrence frequency by accident type was the highest in 187 cases (32.2%) for struck by object, 158 cases (27.2%) for slipping, and 94 cases (16.2%) for being in contact with machinery. Severity is the highest for others such as diseases etc., in the order of being struck by object, being in contact with machinery, falling from above slipping, collapsing, bumping, and burning. Being struck by object, being in contact with machinery, and slipping are high-risk groups, falling from above others, bumping, and burning are medium-risk groups based on the risk assessment using the occurrence frequency and severity of accident. The obtained results are expected to contribute to the safe operation environment subsidy for fishing crews on the stow net fishing vessel.

We collected AIS information on fishing vessels operating near Jeju Island, and analyzed appearance density of the Chinese fishing vessels and inferred the movements of the fishing grounds. AIS information was received from October 16, 2016 to October 16, 2017 and stored on a hard disk through a program called AisDecoder. Unauthorized fishing vessels within the Exclusive Fisheries Agreement Zone (EFAZ) operated near the EFAZ boundary, and the frequency of appearance of fishing vessels were high in the middle waters of Korea and Japan, 252 and 250 fishing zones. Chinese fishing vessels authorized to enter appeared scattered outside the Prohibiting Fishing Zone of the Large Trawlers (PFZLT), and the closer they were to the PFZLT boundary, the higher the appearance density. And the appearance of Chinese fishing vessels with a speed from 0 to 3 knots was mostly outside the EFAZ, showing high density in the waters close to the boundary between Korea and Japan. On the other hand, within the EFAZ, the frequency of appearance of Chinese fishing vessels was also low and scattered. The appearance of Chinese fishing vessels with a speed from 3 to 5 knots mostly shows some variability within the EFAZ, but the frequency of appearance was high and the density was high. The seasonal appearance of Chinese fishing vessels in the waters south of Jeju Island appeared in the southwest in the autumn and then moved south and southeast of Jeju Island in the winter, and in the spring and summer. They were considered going to other fishing grounds without fishing in the waters south of Jeju Island.

We conducted a questionnaire survey to analyze the current status of the coastal composite fisheries, as well as the improvement point in designing a new type coastal composite fishing boat suitable for Korean fishing environments from April to August 2017. The questionnaire composed of 20 questions about the features of the coastal composite fishing boat and fishing work. The survey sites were selected to cover all parts of the country by considering the geographical position. The significance testing for the response results was accessed by  test and ANOVA. The results revealed that more than half (59.1%) of the fishermen operated one day per voyage and operating alone topped with 22.5% in the number of crews, followed by 2 persons (20.3%) and 5 persons (22.1%). The navigation devices had a high rate of installation and GPS plotter ranked first in the devices. In addition, fish finder ranked first in fishing equipment, followed by net hauler. The most inconvenient work that they felt during the fishing operation was fish handing at 49.8% and other general fishing works like setting and hauling line, deck cleaning accounted for about 25%. The hardest work was the accident by ropes wrapped around propeller and the engine trouble came in second. The most inconvenient facilities to the present design of fishing boat was wheelhouse (76.7%), followed by fish hold (38.5%), and deck (35.1%). Furthermore, inconvenient points related to the movement of fishing gear, noise and vibration of engine, slippery deck and small fish hold exceeded 50%.
