Influence of different installation positions of keel on the resistance performance of pilot boat

Yu Xingpeng, Guan Yifeng

Considering that the pilot vessel needs to be equipped with keel keel, pressure wave board and other attachments due to the ship's characteristics and improved navigation performance, these attachments have a greater impact on the total resistance of the hull. Since the bilge keel is widely used as the anti-rolling device for various types of seagoing vessels, its installation position has certain influence on the ship's resistance and anti-rolling performance. In this paper, the ship's resistance test and numerical calculation method are used to compare the resistance performance of the keel with different positions on a 16m pilot ship. That is, when the resistance is relatively small, the proper installation position of the keel is determined to achieve the best. Sailing effect. And verify the reliability of the calculation method and the specific impact of the keel on the total resistance performance.
