Abstract

Information supporting system which is based on real-time prediction of currents to be applicable to the sea trial test of ship is developed. In the system, the spatial distribution of currents at specific time and the trends of variability of currents occurring at specific sites are also given as valuable information for sea trial test of ship. In addition, the system has a capability to connect with a GPS which provides information including speed loss of the ship caused by currents on the way of voyage. With information from the sea trial test, the system is also capable of delivering optimum time and pathways by considering calculated speed loss of ship at specific time and its pathway. Having information described as above, the real-time current prediction system supports and provides functions of not only running the test in an efficient way but also providing valuable information which is encouraged to be used during the test by installing at the ship.

실시간 해수유동 정보를 중심으로 신조선 선박의 실선시운전에서 활용될 수 있는 정보 제공 시스템을 개발하였다. 본 시스템에서는 실선시운전 지원 정보로서 특정시간 해수유동의 공간분포를 예측하여 제공하며, 특정지점 해수유동의 시계열 변동을 예측하여 제공한다. 또한 본 시스템은 실선시운전에 있어 시험선박 운항경로에서의 해수유동 정보 및 선속 손실정보를 제공하기 위하여 GPS와 연결할 수 있는 기능을 가지고 있으며, 이러한 기능을 이용하여 실선시운전시 자동으로 운항경로상의 해수유동 실시간 정보 및 해수유동에 의한 선속손실을 계산하여 제공한다. 실선시운전 중의 정보 제공 이외에, 본 시스템에서는 특정한 시험시간과 시험경로에 대해 선속손실을 예측하여 제공함으로써 최적의 시험시간 및 시험경로를 계획할 수 있도록 지원하는 기능도 가지고 있다. 본 연구에서 개발된 실선시운전을 위한 실시간 해수유동 예측시스템은 효율적인 시험계획과 정확한 해역특성 파악을 지원할 뿐 아니라, 실선에 탑재되어 시험 중에 요구되는 다양한 정보를 제공한다.
