The performance of Stevmanta vertically loaded anchor with a bridle shank is studied. Through the mechanism analysis, the method for determining the bridle shank configuration is proposed. The numerical model is established using the plasticity approach to simulate the installation and mooring processes of Stevmanta anchor. Based on the results, the features of anchors and the influences of geometrical parameters are studied. It is found that the anchor rotation is significant at the initial stage of installation process because of the special shank configuration, and this is helpful for the anchor to get a good diving posture. During both the installation and mooring processes, the anchor will reach a stable state in which the shank configuration will not change. Moreover, the geometrical parameters should be determined by tradeoff while they have significant influences on the performance of anchors.
