5. When the ship needs to be moored when rising or falling, the ballast water in an anchor cabin of the head ballast tank structure is discharged, the ballast water is injected into the tail ballast tank structure, so that the ship is in a tail inclined state, the winch is started to lift the head diving board to a proper height to enable the ship to be in a free floating state, the ship can be moored by utilizing external force (a loader or a power ship) to pull, the diving board is lapped after the mooring is in place, and the ballast water is injected into the head anchor cabin to fix the tail splayed cable rope, so that the anchorage after the ship is moored can be realized. The anchoring solution can avoid anchoring equipment, and greatly reduces the investment cost.

6. The invention is small and flexible, is jointed with the shore to form T-shaped berth, occupies extremely small shore line length, has strong adaptability and is particularly suitable for emergency rescue.

7. As described in '6', when the buoyancy tank and the main hull adopt a split structure, the buoyancy tank can also be used as flexible equipment for national defense combat readiness. The application needs to split the main hull, the crane, the suspension arm, the springboard and the like into a plurality of box body structures or parts which are assisted by quick connecting joints to adapt to various maneuvering and flexible transportation modes of trains and automobiles.
