Here, each of the members of the rescue vessel 10 performs substantially the same configuration, function, and role as the members mentioned in FIG.

The draft control unit 330 may be able to adjust the depth based on the central axis so that the first and second hulls 300 can adjust the buoyancy so as to be semi-submersible. Here, the draft (draft, 吃水) may mean the depth to which the hull 300 sinks when the ship is floating on water, that is, the vertical distance from the bottom of the hull to the water surface. Draft control unit 330 may be provided with a predetermined space for accommodating the liquid inside the first and second hull (300). Here, the liquid may include seawater or a weight for adding a restoring force by lowering the center of the ship, and in the present invention, the buoyancy may be adjusted using seawater.

The stern tank part 355 may be positioned adjacent to the fore tank part 353 through the partition part 352 and a predetermined space is provided so that the stern side is semi-submersible when the liquid is introduced. Therefore, the draft may be controlled by selectively introducing a liquid into at least one of the fore tank part 353 and the stern tank part 355 according to the sea or structural situation.

In detail, it may be necessary to adjust the draft according to the agitation state of the ship. Vibration motion that a vessel sailing on the surface of the sea receives by sea waves can be composed of 3 linear motions and 3 rotational motions. That is, the linear motion is a motion in the fore and aft direction of the ship (Surge Motion, X-axis motion), the motion in the width direction of the ship (Sway Motion, Y-axis motion), and the motion in the vertical direction of the ship (Heave Motion, Z-axis motion) can be made with The rotational motion may consist of rotation in the longitudinal direction of the vessel (rolling motion), rotation in the width direction of the vessel (pitching motion), and rotation in the vertical direction of the vessel (yaw motion). The first and second hull 300 ) can be kept to a minimum or zero state. If the rescue vessel 10 has sunk to the stern side or if it is necessary to approach with a deflection towards the bow side in a rescue situation, the liquid may be introduced into the bow tank part 353 to maintain the semi-submersible state toward the bow side. Conversely, if the rescue vessel 10 has sunk to the bow side or needs to be approached by deflecting to the stern side in a rescue situation, the liquid may be introduced into the stern tank part 355 to maintain a semi-submersible state toward the stern side. Therefore, the draft control unit 330 selectively introduces a liquid into at least one of the bow tank part 353 and the stern tank part 355 to maintain the overall balance of the rescue vessel 10 and stably the structure object 1 ) can be rescued. In addition, the draft control unit 330 may selectively adjust the tank part 351 so that the draft of the rescue vessel 10 is in a semi-submersible state according to the sea state and sea area characteristics.
