CPMC를 이용한 쌍축쌍타 예인선의 조종운동 구속모형시험

Abstract

With growing road congestion ashore, it is inevitable that the sea will be used for linking countries and reducing the distance goods have to be transported on land[5]. In linking among near countries, fleets of barge and tugs take large amount of sea transportation. In accordance with the increase of tug-barge transportation, importance of safe navigation grows. Therefore, building a precise dynamics model for tug-barge system is emphasized for safe navigation. A dynamics model for tug-barge system can be divided into dynamics models of tug, barge, towing rope, and their interaction forces. In this study, prediction of a twin-screw twin-rudder tug's manoeuvrability were conducted through captive model tests in CPMC(Computerized Planar Motion Carriage). 4-DOF manoeuvring equations of motion were used for the prediction. Through numerical simulations of conventional sea trials, manoeuvring characteristics of the tug will be suggested. Simulation results will be compared with IMO interim standards for ship manoeuvrability.
