ON A STUDY OF SHIP-CONTROLLABILITY OF A WIDE-BEAM TANKER USING LARGE SCALE MODEL

This paper presents the results of a study of the ship- controllability of a wide-beam tanker (L/B=5.0). The report consists of the following three parts: estimation of the indices of the maneuvering characteristics of the ship by the method of series test using similar models which are 4M, 10M, 30M in length; determination of whether or not the ship is unstable in course keeping because of so-called "unusual phenomenon"; determination of the feeling of control of the ship with maneuvering characteristics as estimated by the first item, by means of simulation of the ship's maneuvers. The results of this study show that if a large wide-beam tanker has a large enough rudder area ratio, the ship will be controllable.
