Model Tests Of Dragging Hall Anchors In Sand, Yu-Xiao Ren, Zhen-Ming Lei, Li-Qiang Sun, Shu-Wang Yan

Journal of Marine Science and Technology

Hall anchors are often used as the main anchors in great medium ships. However, the methods for determining the holding capacity of Hall anchors when being pulled in soil are rarely proposed. In this study, a series of model tests was carried out using four scaled Hall anchor models to determine the kinematic behavior, trajectory, and development rules of the holding capacity of the anchors relative to dragging distances. Moreover, the holding force coefficients of the Hall anchors in sand were identified after the tests
