According to the statistics provided by Korean Maritime Safety Tribunal for the year 2018, the majority of marine accidents in the past four years have occurred in fishing boats and small-sized boats. Negligent behavior resulting from not looking outside and non-compliance with navigation laws are the primary reasons behind ship collisions. Although safety education and training are reinforced to prevent such accidents, they still occur frequently. Hence, technical methods are continuously being developed to reduce ship collisions caused by human cause. The objective of this study is to reduce ship collisions by employing the WAVE communication system, which has short transmitting and receiving periods that can be incorporated for high-speed small-sized vessels. In this study, the suitability of the communication range was examined, and the appropriate range and timing for avoidance motion were accordingly selected, and a control algorithm based on the same was thereby designed. Consequently normal operation of the collision avoidance system was verified by connecting and simulating the proposed WAVE communication router-controller-steering equipment.

Over the last ten years, the number of entanglement marine accidents has increased more than other accident types. This study analyzed the annual statistical report of marine accidents from the Korea Maritime Safety Tribunal and Korea Coast Guard. Despite some discrepancies between data of the two organizations, it was found that marine accidents involving fishing vessels were more prevalent than those involving non-fishing vessels. In addition, the main floating materials that caused wounded entanglement accidents were fishing nets, fishing gear, and ropes, and the proportion of them was high. Foreign and domestic policies on marine plastics recognize most marine plastics as marine environmental hazards and focus on marine litter recovery and the prevention of marine pollution. The representative Acts related to the marine environment and marine litter, the Marine Environment Management Act and the Marine Waste and Sediments Management Act, recognize marine litter as a type of marine waste, and deal with the types and definition of this waste. However, clearly defining marine waste is difficult. Therefore, this study tried to examine the relevant legal system of marine litter on ship operation and suggested improvement measures. Moreover, the definition of marine litter for the safe navigation and operation of ships was clearly proposed.

Open port has the designated course and traffic jam of ships happens often. This fact may connect to ship crash easily. And the accident happens due to violation of navigation mainly. In ship crash between Neoblue and Shinkwang 7 at incheon open port, the Korean incheon maritime safety tribunal shows that the violation of navigation and duty of attention at the open port would produce ship crash directly. Wherefore, the interpretation and application of navigation are important to protect future ship crash accident. The points of navigation as objects of study are divided into two categories, interpretation and application of navigation on crashing between the ship which navigate the designated course and the ship which enter into the designated course from the another course or outside the course, interpretation and application of navigation on crashing between two or more ships, which navigate violating the navigation every ships and violating agreement rule each other. And as conclusion, I refer the legal responsibility both Neoblue and Shinkwang 7 in detail. The results of this study as follows : First, in case of crashing between the ship which navigate the designated course and the ship which enter into the designated course from the another course or outside the course, public order in open port act can be applied by priority. However, in applying the public order the principle of trust and reasons of crew, cause and effect, the time of navigation application are mandatory considerations. Second, in case of crashing between two or more ships, which navigate violating the navigation every ships and violating agreement rule each other, we should focus on the reasons of crew. Also, the reasons of crew need strict conditions. These means that the awareness of crash danger and recognition of special circumstance including limit state of ships, existence of emergency danger, non escaping crash danger by only observance of navigation. And in case of this state the public order the principle of trust and reasons of crew, cause and effect, the time of navigation application should be considered by priority, too.

Marine casualties are caused mainly by collisions and grounding, due to human error. The SMART Navigation Service is preparing a measure to reduce marine casualties caused by human error and establish an LTE Accident Vulnerability Monitoring System (SV10) to evaluate the danger of collision or grounding for a vessel based on location information collected on land. This service will also share real-time vessel locations and danger information with related agencies to enable them to respond more quickly to accidents on land. In this study, statistical reports on marine casualties and investigation reports provided by the Korea Maritime Safety Tribunal are analyzed, so the percentage of marine casualties that could be reduced using the SV10 service could be identified.

From the viewpoint of navigation safety, it would be best if it's possible to build a bridge whose main span is wide enough, however, sometimes it may not be possible due to geographical or economic reason To construct the bridge on the shipping route, consideration factors for marine traffic safety must be investigated and examined from the viewpoint of marine traffic engineering. This study aims to secure marine traffic safety and maintain smoothly traffic flow through assessment qf these factors. As the first step, examination factors such as traffic volume, ship size and bridge width were assessed quantitatively using marine traffic flow simulation technique.

In December 1998, Act on the investigation and inquiry into marine accidents was amended by inserting new Paragraph (2) of Article 4, which states "Where two or more persons are related to the occurrence of a marine accident when the Maritime Safety Tribunal(hereinafter referred to as the "MST") examines the causes of a marine accident as provides for under Paragraph (1), the MST may disclose the extent to which each responsible person is related to the cause of the marine accident". Based on this new Paragraph, the apportionment system of causation ratio in the ship collision was introduced in February 1999. However the apportionment system is adopted 12 years ago, public debate has continued about the positive and negative aspects of the system. Thus some groups advocate the system for the advantages, but other groups argue that this system should be abolished. Therefore, at first, this study analyzes the adopting background and the main reasons of the pros and cons discussion on the apportionment system of causation ratio in the ship collision. Then we conduct a survey analysis to investigate stakeholder's satisfaction of this new system in the ship collision cases. Finally this study suggests the policy proposal to improve the apportionment system of causation ratio in the ship collision.

At marine construction sites, there are problems with regard to dispute on the responsibility of safety management of chartered barge and its legal issues. In general, demise charter with crew is used for barge charterparty which is committed to the marine construction. Although Chapter 5 of the Korean Commercial Act enact provisions regulating a Time Chargerparty and a Bareboat Charterparty, it is difficult to clarify where the responsibility lies with regard to the safety control of the chartered barge. For this reason, disputes on accountability arise when accident occurs in effect. As a result, parties of the charterparty shift the responsibility on each other and there is increased risk for occurrence of similar accidents. There is no legally required qualification for a head of barge workers who is in charge of barge management. It is not possible to demand the head of barge workers to take charge of tasks which requires professional judgment as a marine technician considering his daily work scope. Furthermore, the barge committed to the marine construction as a form of bareboat charter or equipment charterage is an object which should be managed by safety supervisor of the charterer's marine construction. The charterer bears a duty to manage the safety of the barge. Therefore, the charterer is generally liable for the damage incurred in the course of using the chartered barge.
