The current paper deals with the safety of fishing vessels, which needs more speculations than other ship types. The characteristics of accidents of fishing vessels are rather different compared with other commercial vessels. In the context, the methodology of the formal safety assessment, one of the important issues in the maritime world to enhance the safety of marine vehicles, are reviewed and consulted along with other methodologies to see its applicability for fishing vessels. It is anticipated that further effective measures for better safety of fishing vessels can be identified including due considerations of the aspect of human elements, i.e. cultural environment.

In many cases, fishing vessels operate on a schedule that leads to departure, sailing to the fishing spot, fishing, and sailing to the port of return. Consequently, most of the captains of fishing vessels operated on a single-person navigation duty system rarely have time to rest, resulting in frequent accidents owing to drowsy operation. In addition, accidents frequently occur when a tired captain leaves his duty to an unqualified seaman who does not have the basic knowledge of navigation and sleeps in the bedroom. This problem has been discussed for a long time; however, it has not been solved yet because of lack of proper countermeasures. As a measure to reduce these accidents, this article proposes a certification system for navigational-duty crew of fishing vessels.

The Government of the Republic of Korea has been continuously improving its legal system to ensure marine safety as a precaution against marine accidents. However, despite the ongoing improvement of the legal system, the number of maritime accidents has been increasing steadily, suggesting that the efficacy of the legal system is insufficient. As for recent marine accidents, small fishing vessels (less than 10 tons) account for 44.9 % of marine accidents over 5 years ('13_'17). Therefore, this study investigated the improvement status of the Korean government's legal system for small fishing vessels and the characteristics of related overseas legal systems in order to find a way to further improve marine safety for small fishing vessels. Following the results, the Korean government's laws related to small fishing vessels show a hybrid phenomenon due to the history of merging ('97) and separation ('09) of legal systems for fishing and non-fishing vessels, and it has been concluded that only improvements to construct additional facilities are being performed, and those in a fragmentary manner. In addition, overseas legal systems for small fishing vessels were confirmed to have requirements strengthening the responsibility of owners and operators of fishing vessels and introduced a self-inspection program. Based on these results, a plan is suggested to improve the efficacy of the legal system to ensuree marine safety for small Korean fishing vessels.

A total of 97,623 ships were registered in Korea in 2019. Among these, 65,835 vessels, accounting for approximately 67 % of the total number of ships, were registered as fishing vessels. As with the proportion of fishing vessels, the frequency of marine accidents is also high. In 2020, 2,331 of 3,535 accidents occurred on fishing vessels. Hence, various institutional arrangements are required for improving the safety of domestic fishing vessels. In this study, we examined domestic and international regulations on domestic and foreign control performance related to fishing boats for improving the safety of fishing boats. Additionally, the ratio of the rudder area of 153 fishing boats operating in Korea was investigated to examine the current status of the rudder area design of fishing boats whose design standards have not been clearly established compared to fishing boats. Resultantly, we statistically confirmed that most fishing boats were designing rudder areas because they did not meet international standards. In the future, these analysis results can be used as basic data to prepare rudder area design standards for improving the maneuvering performance of domestic fishing boats.

Maneuvering performance is crucial for fishing vessels, especially under operational conditions that involve frequent course changes and weight variations due to catch. Small vessel accidents account for approximately 60% of maritime incidents as of 2022, mainly attributed to collisions and stranding accidents due to insufficient maneuvering performance. Especially, accidents that occur on small vessels less than 10 tons account for about 65% of all accidents. The absence of international standards presents challenges in accurately evaluating the maneuvering performance of small vessels. In this study, a 4.99-ton small fishing vessel was selected as the target, and a 3d-cad model was created. The commercial numerical analysis program STAR-CCM+ was employed to establish a simulation environment for the vessel's maneuvring motion. Based on this standard loading conditions and weight distribution were considered, 10° / 10°, 20° / 20° zigzag tests and 35° turning test were conducted. The results revealed a tendency for decreased yaw and course-keeping performance and improved turning performance as the hull weight increased. However, in partial arrival and full load departure condition, the manoeuvering performance were relatively poor. Based on this, the need for evaluation of maneuvering and standardized criteria of maneuvering performance for safe navigation of small vessels is presented. Furthermore, it is expected that the evaluation results of maneuvering performance in this study can serve as fundamental data for establishing criteria for evaluating the maneuvering performance of small vessels.

Marine accidents of fishing vessels occupied about 70.5% of the whole marine accidents in Korea from 1996 to 2015, this ratio was not much changed for a long time. A lot of efforts have been taken recently but marine accidents do not reduce. Therefore a fundamental counterplan to decrease accidents in fishing vessel is indispensable for reduction of whole marine accidents in Korea. Since the most frequent occurring accidents in fishing vessels were engine trouble and collision in statistics by KMST (1996~2015), the study focused on them. The cause of engine trouble were poor inspection and maintenance of the mechanical system. The greatest portion of marine accidents was collision, and the biggest cause of the collision was poor watch-keeping. The better watch-keeping will be the best way to reduce the accident. For this reason, it may be necessary for the navigator to make strict precaution on the other vessels under way systematically and keep the regulation for preventing collisions, and for an engineer on watch to make a check the mechanical system periodically for reduction the engine trouble. Instead of penalty, incentive about safe navigation will be helpful for reduce accident as if automobile insurance would do. In order to prevent engine trouble, the fisheries federation establish the repair center. Futhermore the development of autonomous navigation system is necessary to reduce the marine accident.

According to amendments of ship safety act which comes into force from 4 Nov. 2007, the amended stability criteria should be applied to the small vessels of 12m or more in length. In this paper, the dimensions of domestic small vessels and the casualty reports of capsizing accidents are analyzed. And 58 ships are sampled, modeled for the investigation of the stability performance. Based on the regression analysis of the model ship's allowable metacentric-heights under several stability requirements, stability criteria for small fishing vessels and cargo ships are proposed.

In recent 5 years, the 70 percent of the ship's accident was occurred in the fishing vessels, and most of them were the engine troubles and collisions. The capsizing accident was comparatively low portion of occupation, which took only 2 percent, but the scale of accident and the loss of lives and property are known very tremendous. In this paper, it was examined for the stability provisions of fishing vessels in domestic and international to reduce the capsizing of them. Also, it was made an analysis for the case of capsizing accidents to suggest the measures against the capsizing.

This is a basic study to establish marine activity criteria based on the seakeeping performance of less than 10-tons fishing vessels. These vessels account for approximately 95% of Korea's currently registered fishing vessels, and accidents and loss of life are also occurring during marine activities such as navigation, and fishing. Accordingly, the Ministry of Oceans and Fisheries has set a regulation of vessel traf ic control to restrict the operation of fishing vessels when the high seas watch takes effect, but it is applied equally without criteria according to the ship ton level and wave height; therefore, many differences may exist in ship fluctuations. Because the fluctuation of the ship owing to the wave height can be a factor in marine accidents by reducing the sense of boarding and performance of equipment, the seakeeping performance must be reviewed during waves to secure safe marine activities such as navigation and fishing. However, the review for the fishing vessel of established marine activity criteria based on the seakeeping performance is insufficient. Accordingly, the seakeeping performance was evaluated for a 10-ton class (G/T 9.77 tons) fishing vessel in Korea, and the level of marine activity according to the significant wave height and ship speed was interpreted by applying the operation and survival of the established seakeeping performance criteria. The analysis results indicated that the roll of the ship exceeded the operation criteria from 0.4m and the survival criteria from 2.2m. The pitch of the ship exceeded the operation criteria from 1.7m and did not exceed the survival criteria until 3.0m. However, the rolling exceeding the survival criteria from 2.2m may not be safe. Therefore, fishing vessels with less than 10-tons can leave before the high seas watch takes effect. However, they did not satisfy the criteria for evaluating the performance of the sea in relation to marine activities. Although this study was limitedly evaluated for 10-ton fishing vessels, it is expected to be of great help in preparing marine activity criteria.
