The approaching waters of Po-hang port will be increased the traffic volume and passage of larger vessel according to the opening of Young-il new port in 2006. But the adjacent area of Po-hang port still exist the danger elements of safe navigation, the disordered navigation and traffic congestion. Therefore the safety of traffic must be improved in Po-hang vicinity area. This paper describes the status of marine traffic flow and navigational characteristics based on the marine traffic survey using the exclusive software, and the results of marine traffic survey classify into the ship's types and tonnage and track history of passing ships through the statistical method. Finally the examinations of main traffic route, traffic flow and navigational characteristics are discussed, and these results can be utilized the best design of ship's routing at the Po-hang approaching water.

The traffic volume will be increased and the traffic of larger vessel could be multiplied in the Pohang port by the opening of the Young-il new port in 2006. Unfortunately, however, potential danger factors to the safe navigation, disordered navigation and traffic congestion are still existing in the Pohang port and approaching waters. This paper describes the status of marine traffic flow and navigational characteristics based on the marine traffic survey using the exclusive software, and the results of marine traffic survey classify into ship's type, size and track history of passing ships through the statistical methods. Finally the examinations of marine traffic route, traffic flow and navigational characteristics are discussed. These results can be used for the best design of ship's routing at the Pohang waters.

만재된 광탄선이 UKC가 작은 수역을 진입할 때 후진 기관을 사용하게 되면 통상의 경우와는 달리 급격한 좌선회 현상이 발생한다. 이 현상은 속력이 4노트 이상에서는 두드러지게 발생하나 3노트 미만에서는 거의 발생하고 있지 않다. 이 연구에서는 포항항에 만재된 광탄선이 선석에 접안할 때까지의 발생하는 현상을 기술하고 그 원인을 밝혀 보고자 한다. 이 원인 추후 이론적인 검토가 필요한 사항이지만 이 연구에서는 추론 가능한 사항은 선미부의 방형비척계수(CB), 작은 UKC 등을 고려한 통상적으로 작용하는 배수류의 측압작용과 좌현 선미의 선저에 배수류의 쌓임에 의한 힘으로 검토하고자 한다.
