This research does by purpose that present safe navigation plan for ships during doing dredging construction with dredger crossing waterway of Gadeok Dredging operations need to build sunken tunnel that cross the bottom of the sea under waterway of Gadeok for access road construction between Busan- Geoje. Accordingly, dredger must cross and dredge waterway of Gadeok fatally. There is possibility of marine accident of collision for latent danger situation of ships to navigate waterway of Gadeok relatively. Therefore, safe navigation plan of ship is groped in reply and its countermeasure is presented. Firstly, navigating traffic in daytime was forecasted less than 20% of its maximum capacity through estimating the traffic volume and traffic congestion The proposal was presented to execute dredging operations in three-step and to establish temporary waterway after reviewing waterway design principles. The role of VTS center was emphasized in the new Busan Port, lastly.

According to the many ancient literatures, it is said to be that Merchant Prince, Chang Pogo in unification Silla had traded with not only China, Japan but also Arab-Islam Countries, but unfortunately there is no definite records about this. Therefore in this study the writer would like to presume the sea routes of Merchant Prince, Chang Pogo in a unification Silla. For the purpose of this study the writer would like to study the reference books and materials regarding to the sea routes of prehistoric age and ancient three countries of Kingdoms and unification Silla. Especially the writer consider “The Work of Routes and Kingdoms” of Ibn Khurdarhbih regarding to the ancient sea routes of Korea, China, Arab-Islam Countries, and also the writer consider the ancient sea routes of Tang Dynasty in China and Ryukyu Kingdom in Japan. About this methodology of this study, the writer believe that the sea routes of today is the results of ancient sea routes, and this ancient sea routes could not be changed forever except special circumstance. According in this study the writer would like to persume the sea routes of Merchant Prince, Chang Pogo using like this methodologies. This presumption of the writer is originated on the basis of The Work of Routes and Kingdoms written by ancient Arabian Geographer, Ibn Khurdadhbih in the early years of 9th century. The Work of Routes and Kingdoms is geography, and the principal contents of this geography are the activities of Arab-Islam merchants and Chinese Merchants between Arab-Islam countries and China from 9th century to 11th century by ancient sea routes. But surprisingly in this geography, Silla was marked, and another ancient Arabian geogrpher, Al-Biruni marked Silla on his map, Qanun Al-mas'udi in the 9th century, and also another ancient Arabian geographer, Al-Idrisi marked Silla on his map in the 11th century. Especially Al-Biruni expressed the longitude and latitude of Silla on his map, he expressed Silla as following. “at the extreme end of China toward the East and few people travelled to it by sea”. Therefore the writer would like to presume that Arab-Islam merchants had traded with unification Silla in the 9th century, and also Merchant Prince, Chang Pogo had traded with not only China, Japan but also Arab-Islam Countries using above ancient sea routes in the 9th century.

In Gwangyang port, huge reclaiming work and developing harbor facilities are underway to built industrial complexes. So it is estimated that towing barges will increase and make overtaking, head-on, crossing situations with a lot of cargo vessels in narrow passages. And it is possible to cause severe marine accidents inside of the harbor. This paper has a purpose to produce some policies making navigational safety of towing-barge on Gwangyang Hysco temporary passage. So it is considered how the change of marine traffic capacity and the risk factors in passage navigation influence to towing-barge navigation. And also the questionnaire survey of pilots and VTS operator was conducted to find out what they think about the navigational safety of towing-barge incoming and outgoing in No.1 Yulchon industrial complexes.

A Collapse of bridge by ship's collision to the bridge post may lead a great calamity. This paper investigates on avoiding collision between a ship and bridge by improvement of environmental factors, submitting a counter plan of reducing collision effect by triangular type of collision protecting bar and ship maneuvering skills. Putting up collision protecting bar fences of triangular type around the bridge posts would decrease the collision impact force by 75 percent.

항로를 횡단하여 건설되는 교량이 증가하고 해상교통의 증가에 비례하여 항로의 혼잡도가 증가하는 만큼 선박과 교량의 충돌우려가 커지고 있다. 선박과 교량의 충돌은 단순 접촉사고가 아닌 재난급 사고의 개연성이 크다. 직접 손괴를 일으키는 큰 충돌이 아니더라도 선박과 교각의 충격진동에 의하여 교량상판이 균형을 잃고 연쇄 붕괴하는 일이 종종 발생하여 많은 인명의 손실이 발생하고 있기 때문이다. 적정 교각 폭, 교각의 시인성 증진을 위한 표지와 등화의 설치 및 점등방법 등의 환경 여건 개선, 충돌방지공의 효과 검토, 교량 통과전 사전 점검사항, 교량 부근에서 선박의 조종성 유지방안, 예선의 효과 연구, 관제기법과 안전규정, 불가피한 충돌이나 접촉의 경우 손실 감소대책과 충돌방지공의 효과 등 다각적인 연구가 필요하다. 면피용 탁상이론을 배제하고 현장실무의 경험을 바탕으로 실효적인 방안을 제시하고자 한다.

VTS 시스템의 비약적인 발전에도 불구하고, 현재 물동량의 증가에 따른 선박 교통량 및 고위험군 선박의 증가로 인해 언제든지 사고의 내연성을 가지고 있다. 또한 입출항 항로에서의 어로행위나 무단횡단, 부두 신설로 인한 해상교통 여건의 어려움을 가지고 있는 것이 현실이다. 이런 상황에서 고위험군 선박 즉, 거대형선이나 대형 원유선, 구조물 운송 예부선의 해양 안전 사고 예방을 위해 특별관리체제(전담관제)를 구축함으로써 항로의 안전성 확보 및 충돌 예방을 위한 방안을 제시하고자 한다.

정부의 북극항로 시험운항이 시행된 2013년 NSR횡단 선박 척수는 전년도에 비해 54%가 늘어난 71척에 이르렀으나 실제 화물수송량은 당초 예상량인 150만톤에도 못 미치는 1,355,897톤으로 전년도에 비해 7.5% 증가에 그치고 말았다. 이는 2013년 하절기 북극해의 얼음이 2012년도에 비해 훨씬 적게 녹았기 때문으로 분석되고 있다. 그러나 지구온난화로 인한 전체적인 해빙 크기의 감소추세는 큰 틀에서 벗어나지 않고 있으므로 NSR의 선점을 위해서는 화물의 경제성 평가와 더불어 고효율선의 운항에 대비할 필요가 있다.
