Due to the simplicity of communication structure using RS-232 and RS-422, the majority ships have still adapted on these communication interfaces and have constructed their own communication network in the ship. NMEA-0183 is the one of standards for BNWAS(Bridge Navigational Watch Alarm System) and currently being used in many countries. BNWAS utilises diverse sensor devices, GPS, AIS and so on for monitoring the status of ships and their deployments and environmental information(temperature, humidity, wind speed/direction, water temperature/current etc…). This paper proposes the use of any image sensors in NMEA-0183 environment and verifies possibility with certain video qualities through the experiment results. Furthermore the paper gathers videos and monitors the change of their qualities depending on the number of NMEA messages on RS-232 communication link. Finally we make conclusion that our proposal is sufficiently appropriate for ship monitoring system in the NMEA-0183.

An Integrated Bridge System (IBS) is not an officially defined term, but a concept of which integrates on a consol at bridge the primary functions of stand-alone navigational aids and communication instruments or of stand-alone units which are integrated i.e. ARPA ECDIS It aims to enable officers on navigational watch to perform their duty without impairing proper lookout. IBS has been taking shape through a rapid development of navigation and communication systems in relation with bridge configuration bridge work station and one man bridge operation system. IBS related matters have been considered for years and is on the agenda of the International Maritime Organization(IMO) for its technical details and safety aspect of possible one-man watchkeeping at night. However IMO has made it clear that human element should be the key factor in considering IBS and single watchkeeping issue. In the development of IBS ergonomic element and human psychological aspect have been more emphasized than technical requirements. This paper refers to documents presented to the IMO and its progress made in various IMO technical meetings on the development of IBS which is perceived as an effective aid to proper bridge lookout and those standards adopted by classification societies on the composition of workstation at bridge in order to identify the international trend on regulating required equipment function of workstation of IBS the regulatory review process and technical recommendations related thereto.

최근 선박 및 해상 물류 자동화는 물류증대와 복잡한 선박의 운용에 비하여 근무조건이 상대적으로 열악한 형편이다. 때문에 과도한 선원의 업무량으로 인하여 IMO(International Maritime Organization, 국제해사기구)에서는 선박이 운항함에 있어 해상에서 발생 할 수 있는 모든 사고(인명, 해상오염, 선박의 손실)를 미연에 예방할 수 있는 최소한의 장비로 선교항해 당지경보시스템 (BNWAS)을 모든 여객선과 국제항을 운항하는 150GT 이상의 모든 선박에 탑재하도록 하고 있다. 본 논문은 선교항해 당지경보시스템의 Alarm 상태를 원격에서 관리할 수 있는 서버 관리 프로그램을 개발하여 적절한 조치를 할 수 있는 지능형 선교항해 당지경보시스템을 제시하고자 한다.

About 90.5 % of barge-towing tugs weigh less than 200 gross tonnage and most are served by the master alone. They are also not subject to the regulations on the working hours and manning levels stipulated in the Seafarers' Act. Therefore, the master of barge-towing tugs cannot take sufficient rest during the navigational watch. Moreover, barge-towing tugs do not satisfy the human seaworthiness due to the inevitable performance of the navigational watch which must be alternately undertaken with an unqualified person, called the "Boatswain". Furthermore, there are many cases in which the master or owner of a tug fails to comply with the additionally required minimum manning levels stipulated in the Ship Of icers' Act when a tug tows a barge. This study reviews the following: (1) the regulations on the working hours and manning levels that are stipulated in the Seafarers' Act, (2) the regulations on the minimum manning levels for ship of icers of the tug's deck part that are stipulated in the Ship officers' Act, (3) marine accidents in the barge-towing tugs. As a result I suggested that one additional deck officer should be on board when a tug tows a barge through the revision of the minimum manning level for ship of icer on the deck part in order to prevent marine accidents of tugs effectively. Especially, the Act on the Punishment, etc. of the Serious Accident came into effect on January 27, 2022. If marine casualties occur continuously at sea due by the same cause, and the cause of such marine casualties would be turned out by the fatigue of the ship of icer caused by insufficient institutional arrangements, the administrator of competent Authorities of Maritime and Port could be punished, so it seems to prepare for it.

Since July 2006, marine traffic safety management system have been enforced to support the vessels transiting across the coastal area and the vessels coming in and out of ports in southwestern coastal area where heavy traffic density and marine casualties occurred frequently. The marine traffic volume for the marine traffic environmental assessment was measured by the information from RADAR and AIS system in the area. The distributions of marine casualties were analyzed in the main routes and traffic separation schemes during the last five years and the navigational dangerous elements were investigated with the influence of natural environment, the distribution of fisheries and survey questionnaire. Marine accidents of merchant ships have a tendency to decrease gradually but in case of fishing boats, the rate of marine accidents have a contrary results in this area during the last five years. The dangerous elements on navigation appeared to be the dense force from June to August, fisheries activities and the vessels which not follow the compulsory watch on VHF-band radio communication equipments.

The necessity of improving manning standards in the Ship Officer's Act has recently been strongly advocated by the fisheries industry. The fisheries industry maintained the position of the relaxation of current manning standards. However, the Labor unions, Marine Officers Association, and Radio Officers' Association persisted to strengthen the standards or to keep the current standards. This paper studies the appropriateness of current manning standards and processes its improvement scheme to secure the safe operation of vessels.

Now AIS (Automatic Identification System) has been under full operation for ocean-going vessels, and it is expected not only to identify target ships but also to take collision avoidance using AIS information with Radar and ARFA information in restricted waters. AIS information is very useful not only for target identifications but also for taking collision avoidance, but OOW (Officer OF Watch-keeping) should take care of systematic observation of AIS because of miss-operation or malfunction of AIS. In this paper, we propose the application of Onboard Ship Handling Simulator with visual system displayed 3D scene added AIS performance such as blind areas of Island, microwave propagation, ok. and maneuvering simulation using TK models, applied real time AIS information and research the effectiveness of this system for ship handling in restricted waters, and discus the principal issues through the on board experiments. Conclusion will be expected that; 1) systematic observation of ASS information using visual scene simulator with AIS information will be effectively done, 2) observation compared with Radar and ARPA information will be also useful to make a systematic observation, 3) using the recording and replay function of simulation will be useful not only for systematic observation but also to measure and to encourage officers' skill.

The purpose of this study is to contribute to the prevention of ship collisions by investigating real ship collision cases and statistically analyzing causes of human error for captains and Officers of the Watch (OOW). This study encompassed a total of 109 cases for 218 vessels, which were suitable for the analysis of ship accidents between merchant ships or merchant ships and fishing boats over the 7 years from 2010 to 2016. Data was collected while classifying vessels according to type, Give-way and Stand-on vessels, along with the cause of human error. Factors causing human error were identified after focusing on the cause of each collision given by the OOW ; frequency and cross tabulation analyses were conducted using SPSS, a statistical analysis tool. As a result, the main causes of human error by an OOW in a ship collision situation were that lookout was neglected in a Give-way vessel including radar surveillance (74.3 %) or continuous observation of an opponent vessel was carried out (17.4 %). A major factor for Stand-on vessels was failure to act to avoid collision with another vessel (63.3 %). In particular, most neglect for lookout type merchant ships occurred after the opponent ship was first observed, and a common cause of lookout neglect and neglect of duty was a focus on other tasks during navigational watch time.

This paper is the study of BNWAS based on TLC. The functionality of BNWAS and its operations are investigated through its international standard. But the BNWAS to be used currently in the ship have difficulty in monitoring. Several kinds of data are generated from many equipments in BNWAS, such as NMEA-0183 data or NMEA-2000. Although these data are mainly used for the safe navigation of ship, their usability may be enhanced if they are managed to control the BNWAS equipment with sensors. The purpose of this system is prevent the marine accidents on sailing voyages due to drowsiness of watchers. On Night sailing, watcher is collected the navigation information from multiple devices and he determines the safe operation of the ship through continuous monitoring.
