Abstract

Traffic risks in fairway and harbour area increase lately according to be a sharpe change of ship's size and speed. It becomes hot issue to design a fairway, which's width is important to lower traffic risk and ensure navigational safety. The current design making a fairway and width do not focus on maneuvering motion of a large ship, but traffic risks are clear on reflecting the design of fairway, specially on width. To contact with these problems, this research proposes how to determine fairway' width in consideration of traffic volume. it suggests several situations of marine traffic congestion as like narrow channel and harbour area. here uses 162 simulations in MTS Ver.1 developed. Acquired simulation's results, environmental stress dates, figure in a model that relates with required fairway' width and allowable traffic volume. In added, suggested model compares current design with an width.

최근 선박의 대형화 고속화가 진행되면서 항만의 변화와 항내 수역 혼잡의 증대 등 해상 교통에 많은 위험 요소가 늘어가고 있다. 최근 가장 첨예하게 대립되는 것이 항로폭을 적정하게 결정하는 문제이다. 현행의 항로폭 설계법은 해당 수역을 통항하는 최대 선박의 운동 성능을 중심으로 설계되고 있지만, 다양한 종류의 선박이 혼재되어 운항하고 있는 해상교통 환경을 고려하지 않고 있다. 본 연구에서는 항내 수역의 다양한 교통 상황을 설정하고, 교통(용)량을 고려한 항로 설계법을 제안하고 이를 현행 항로설계법과 비교하였다. 이를 위해 기존 항로 설계 방법을 정리하고, 항내 수역을 대상으로 하는 162개의 해상교통 시뮬레이션을 실시하였다. 이 결과를 바탕으로 각 선종별 선형 구성 및 교통량에 따른 환경스트레스값 즉 운항위험도를 추정하였다. 허용 교통량에 대한 적정 항로폭 모델식을 구하고, 실제 수역에 적용하였다. 현행 설계법에 따른 항로폭과 비교하고 그 유용성을 확인하였다.
