2019년 2월 28일 용호부두에서 러시아 화물선이 예선을 사용하지 않고 출항하면서 계류 요트와 1차 충돌하고 이어 2차로 광안대교와 충돌하였다. 선박의 진행에 따라 전심의 위치가 변하며, 특히 예선을 사용할 때는 전심의 위치가 달라지게 된다. 조선자가 예선의 도움을 받는 상황에서 의도하는 조종을 하기 위해서는 예선의 예항력의 크기와 전심의 위치 그리고 속력을 고려하여야 한다. 본 고에서는 예선지원여부와 접이안 자세에 따른 선박조종법을 소개하고, 안전조선 대책을 제시하였다.

This paper is concerned with the design of neural-network based autopilot control system. In this paper, the back-propagation algorithm is introduced and explained in detail. The system identification method based on neural networks for ship motion is developed and its efficacy is verified by using a simple ship maneuvering model. Problems which may arise in a complex maneuvering model are then discussed. The neural-network based system identification method developed in this paper can be used effectively for reconstructing the ship maneuvering moodel which is known to have nonlinearity.

경인 아라뱃길이 2011년 10월 개장을 앞두고 있다. 경인 아라뱃길이 시작되는 경인항 서해갑문 입출거시 예선사용기준에 대한 연구는 선박운항의 경제성 측면에서 매우 중요한 의미를 지닌다고 할 수 있다. 통상 선박의 크기(톤수)에 따른 예선의 소요마력 및 사용 척수는 대상선박의 크기, 모양, 접근수로, 부두시설의 위치 및 종류, 기타 환경조건 등의 영향을 받으며, 선체에 작용하는 수면상부의 풍압력과 수면하부의 유압력을 고려하여 규정하고 있다. 따라서 본 연구에서는 국내외 예선 규정 및 대상선박에 대한 예선 조종시뮬레이션을 통하여 경인항 서해갑문 입출거시 사용되는 예선의 기준을 설정하였다.

We carried out the maritime safety audit for Sandal Water Bridge constructed between Geje-Do and Sandal-Do in 2015. To study as to whether can be secured the marine traffic safety for this area, this research investigated and performed the marine accident, marine traffic volume, the marine traffic flow simulation and shiphandling simulation. It is considered to be required the quantitative guidelines for maritime safety audit including audit target area and formal audit object etc.

In the maritime universities, cadets of deck part should practice on board training using training ships of university or merchant vessels of company for 1 year according to STCW Convention. For training period, trainees are educated many education items as to positioning ability, chart work ability, vessel operation ability and cargo operation ability etc. Among many abilities, vessel avoiding ability which is demanded as a basic ability for deck officer can't be gained easily, because avoiding maneuver of ship controlled by cadets is not allowable regally and encounter situations occur randomly. This paper investigated CPA to the various encounter types with other vessels during the ocean going navigation of T.S Hannara. We analysis danger degree per each encounter type, and proposed a basic material of efficient training education about proper look-out and avoiding maneuver.

Recently the large sea bridge's construction crossing harbor and main ship's route have been propelled in the domestic so that it is active for the smoothly traffic flow of inland transportation and road user's convenience. However, it can bring about the trouble to ensure marine traffic safety if it is built that sea bridge's construction sets to an economy principle in the extension of the land road system. We're adopting Ship Handling Simulation in representative method for the influence assessment of marine traffic safety and danger elements beforehand. This research attempts to show the problems through the comparison and analysis of the reports relating to the sea bridge construction for 4 organization possessing Ship Handling Simulation. Finally, We offer the necessity of standardization on performing and assessment method of simulations.

Recently, a vessel's maneuvering performance is considered to be an important subject to secure safety at short sea shipping. Especially the high turning performance, which is required to avoid the marine pollution by the ships that was grounded, becomes more severe. In this paper, we discuss the effect of increasing rudder force on turning performance of short sea shipping ship by free running test in towing tank. First of all, we make the 47K PC model ship and high-lift rudder using Coanda effect. And we make the free running test system for the turning test in towing tank. And also we perform the turing test of 47K PC model in several changes of Coanda jet momentum and evaluate the turing performance such as advance and tactical diameter. Finally, we confirm that the increasing of rudder force is very effective to improvement of turning performance of short sea shipping ship.

Shin(2015) etc. published use of smart phones on the effect the use of smart phones released in the ship duty performed by survey of using smart phones Status and Usage in previous studies, soon as the survey provided this environment(36% on sailing) where you can use your smart phone from the ship, at the risk of officers using survey questionnaires were analyzed smart phones that use about twice the risk than before. In this study, maritime those who have experienced a period of sailors aboard a diagnostic test subjects Ship Handling Simulation analysis evaluation item of Maritime Traffic Admit, Proximity evaluation of a ship evaluation, by measuring the degree of danger that the subjective evaluation and control of the ship evaluation to evaluate the risk on navigation safety. Also indicated the risk of a smart phone quantitatively by measuring the time that the awareness of dangerous situation depending on using smart phone or not.
