The invention relates to a large-scale annular crane for a ship. The large-scale annular crane comprises a plurality of stand columns, an annular supporting structure, a cart system, a crane carriage and an electric control system, one end of the stand column is welded to a ship deck, the other end of the stand column is welded to the annular supporting structure, and an annular rail is arranged on the annular supporting structure. The cart system comprises a cart, and the cart rotates along the annular track; the crane trolley is arranged on the cart; and the electric control system is used for controlling the cart and the trolley. The large-scale annular crane is matched with a floating test platform for use, can realize underwater lifting of a conventional model, can also realize state control of model rotation and the like, and is suitable for tests of offshore offshore wharf water areas or other water area conditions.
