Hereinafter, the operation of the deformable floating body according to the embodiment of the present invention shown in Fig. 2 or 5 will be described in detail.

Usually, the deformable float 100 sails in a state in which the submersible 400 is raised. If the weather conditions deteriorate, such as a severe wind or blue wave or a deterioration of the marine environment due to a tide change, the deformable floating body 100 sails in a state in which the submerged body 400 is lowered. At this time, as the receiving area of the floating body 100 is reduced, the floating body 100 is less affected by the blue wave, and the wind resistance is improved, and thus, stability can be achieved.

In addition, the deformable floating body 100 performs a heaving motion by sea fluctuations during sailing or berthing. The submersible body is controlled through a controller (not shown) and a driving part (not shown) in response to the hebbing motion generated at this time. By raising and lowering the 400, the hull 200 can be controlled to a constant height.

Therefore, according to the deformable floating body 100 according to the embodiment of the present invention, by controlling the rising area by controlling the rise and fall of the submersible 400, the hull 200 in spite of the blue or tide in the sea Can maintain equilibrium.

8 is a view showing a state that the floating body according to an embodiment of the present invention performs the unloading operation between the other container ships.

As shown, the side of the deformable float 100 serving as a ship or mobile port and the side of the container ship S are docked, and the crane 500 on the float extends in the container ship S direction. Carry out loading of cargo (C). Since the floating body 100 can load up to several tens of tons of cargo, the weight that the floating body 100 receives varies greatly depending on the load of the cargo.

When there are many cargoes loaded on the deformable float 100, the hull 200 sinks down. At this time, when the diving body 400 is lowered, the hull 200 is raised due to the change of buoyancy applied to the diving body 400. Therefore, the height of the hull 200 can be maintained constant, it is possible to block the possibility of the waves pushed on the platform.

When less cargo is loaded on the deformable float 100, the hull 200 rises upward. At this time, when the submersible 400 is raised, the hull 200 is lowered due to the change of buoyancy applied to the submersible 400. Therefore, the height of the hull 200 can be kept constant, and the floating body 100 can be prevented from being placed in an unstable state.

Despite the effects of wind, blue, or tidal currents on the deformable float 100, the crane 500 can unload cargo C stably and smoothly. The cargo (C) shipped in) is also stored securely.

According to the embodiment of the present invention, the stability of the floating body 100 itself can be increased, and also stable cargo unloading with other container ships becomes possible. Floating body according to the present invention can efficiently handle the cargo transportation of container ships that require deep water as well as general ships and can function as a mobile port will contribute to strengthening port system competitiveness in the future.
