A Study on the Maneuvering Characteristics of a VLCC by Using of her Control Surface In a Curved Narrow Channel

굴곡된 협수로에서 자력조선에 의한 VLCC 의 조종특성에 관한 연구

The safe passing maneuver of a large vessel along the designed course through a narrow channel in the flow of strong current is greatly related with her maneuvering characteristics. This paper treats maneuvering characteristic of a large vessel changing her course with the use of her control surface in a narrow channel with strong current. In this paper, the author proposed mathematical models of calculating maneuvering motions of the very large LNG tanker altering course using her control surface and calculated passing tracks of the vessel through the channel and compared the calculated results with those of maneuvering simulations by a desk-top simulator. In general the motions with the calculated values and the simulated motions are well coincided with each other.
