Underwater stability is one of the important overall performances of deep-sea human occupied vehicles (HOVs). The stability of HOVs is measured by metacentric height (GB), which is closely related to the operation and safety of HOVs. The metacentric height of HOV changes due to the change of ocean parameters and its own ballast during movement. Based on the basic formula of metacentric height and the buoyancy loss calculation method for HOV pressure structure, buoyancy material and hydraulic oil, a mathematical model of metacentric height for HOVs was established in this paper, and a method of underwater stability analysis for HOVs was proposed. Taking “SHEN HAI YONG SHI” HOV as the research object, the underwater stability of HOVs was calculated and analyzed, and the variation law of the metacentric height of HOVs was obtained, which can provide a reference for the design of HOVs.
