A navicular structure having a tank structure shared between a tanker and a floating offshore storage structure, and a method for designing a navicular structure; wherein wing cargo tanks (12) and shipboard and ship-bottom sections (13) are provided sequentially toward both outer sides of the ship from middle center cargo tanks (11) in bilateral symmetry in the beam direction, the tanks excluding slop tanks (14) are counted, and the number (Nw) of wing cargo tanks (12) on one side of the ship is set greater than the number (Nc) of center cargo tanks (11). A section placement particularly resistant to shipboard damage is thereby planned with as little increase as possible in the number of costly tanks, i.e., in the surface area of the watertight bulkheads for partitioning the tanks, the tanker remains easy to use, the cost is kept competitive, and the section placement can be used in a floating offshore storage structure. A floating offshore storage structure that has reduced design costs and shortened lead time is provided inexpensively and quickly.
