The present invention relates to an intrusion prevention system for a ship, and more particularly, to an intrusion prevention system for a ship for preventing or preventing an unauthorized boarding of an intruder such as a pirate.

The seizure and the capture of pirates, which are frequently occurring in Somalia, have recently become an international problem. International societies have been preparing voluntary measures such as mobilization of military forces in order to eradicate these pirates' activities. However, it is not enough measures to provide weapons to ships themselves because they are not allowed in domestic and foreign laws. Therefore, as a countermeasure currently being taken, measures for preventing or preventing intruders entering or approaching the ship are mainly sought.

The entry into the ship by pirates is mainly through the easily accessible side of the ship. Normally, it approaches the side of the ship through a small vessel, and then climbs up the rope with a hook, etc., Method is being used. Therefore, in order to prevent seizures by pirates or the like, measures should be taken to prevent climbing from approaching to the side of the ship or through the side of the ship.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It is to be understood, however, that the following examples are provided to facilitate understanding of the present invention, and the scope of the present invention is not limited to the following examples. In addition, the following embodiments are provided to explain the present invention more fully to those skilled in the art and those skilled in the art will appreciate that those skilled in the art, Will be omitted.

1 is a schematic view showing an intrusion prevention system for a ship according to an embodiment of the present invention. FIG. 1 schematically shows an intrusion prevention system for a ship according to the present embodiment, centering on a transverse section of a ship, and it is noted that only one side is shown for convenience.

Referring to FIG. 1, the intrusion prevention system 100 for a ship according to the present embodiment is for preventing an intruder such as a pirate from entering the ship through a side portion. The intrusion prevention system 100 includes a ballast tank 110 in which seawater is stored, A steam jet nozzle 140 and a seawater jet opening 150 for spraying stored seawater in the tank 110 to prevent access by an intruder.

The ballast tank 110 is for providing seawater to the water cannon 130 or the like and may include a conventional ballast tank for adjusting the waterline or the posture of the ship. In the case of the intrusion prevention system 100 for a ship according to the present embodiment, the seawater is supplied to the water cannon 130 or the like so that the seawater can be injected into the side portion of the ballast tank 110 .

The ballast tank 110 may be provided in various positions within the ship. For example, the ballast tank 110 may be provided at various positions within the ship such as a side portion, a tail portion, and a bottom portion. In this embodiment, the ballast tanks 110 disposed on the front side are exemplified. In this case, it is possible to shorten or simplify the piping line for providing the seawater in the ballast tank 110 to the water cannon 130 or the like There is an advantage.

Meanwhile, a seawater supply pump 120 and a seawater supply line 121 may be disposed in the ballast tank 110. The seawater supply pump 120 and the seawater supply line 121 can supply the seawater in the ballast tank 110 to the water cannon 130, the steam spray nozzle 140, and the seawater jet opening 150.

The seawater supply pump 120 may be disposed at the lower end of the ballast tank 110 in consideration of the level of seawater in the ballast tank 110. This arrangement allows the seawater supply pump 120 and the seawater jetting port 150, which will be described later, to be disposed adjacent to each other. As described later, the seawater jetting port 150 discharges large-capacity seawater overboard compared to the water cannon 130 and the steam jetting nozzle 140 on the upper side, and is disposed adjacent to the sea water jetting port 150 as described above. The seawater supply pump 120 can provide sufficient pump pressure to the seawater injection port 150.

On the other hand, the water cannon 130 can prevent the intruder such as a pirate from approaching the side portion by discharging seawater in the ballast tank 110 in the form of water cannon or high pressure water. Since the water cannon 130 used to prevent boarding or intrusion of pirates is well known, the detailed description of the water cannon 130 itself will be omitted.

The water cannon 130 may be provided on the leading side and may be disposed on a freeboard on the ship's waterline. At this time, the waterline may mean the load line or reference waterline of the ship. Alternatively, the water cannon 130 may be provided on the upper side of the side of the ship and disposed adjacent to the upper deck U. The water cannon 130 arranged as described above fires the water cannon toward the lower side of the ship side to prevent access of the external intruder.

If necessary, a cannon mounting portion 111 for installing the water cannon 130 may be provided on the front side of the ship. The cannon mounting portion 111 can be formed such that the side portion of the ship is drawn inwardly to the inside of the ship to a predetermined degree or drawn in a stepped shape in a stepped shape.

On the other hand, the steam injection nozzle 140 can prevent steam from being sprayed to the side portion, thereby climbing the outside intruder to the side portion. Steam injected from the steam injection nozzle 140 can be generated by heating seawater in the ballast tank 110.

If necessary, a heat exchanger 141 may be provided on the seawater supply line 121 for supplying seawater to the steam injection nozzle 140. The heat exchanger 141 can generate steam sprayed from the steam spray nozzle 140 by heating the seawater supplied to the steam spray nozzle 140 through the seawater supply line 121. At this time, the heat source of the heat exchanger 141 may be provided through the waste heat circulation line 142 for reusing the waste heat in the ship. The seawater supplied to the steam injection nozzle 140 through the seawater supply line 121 can be circulated through the waste heat circulation line 142. The seawater supplied to the steam injection nozzle 140 can be circulated through the waste heat circulation line 142, Can be heated directly or indirectly through the heat exchanger.

On the other hand, the seawater jetting port 150 is disposed below the water line of the side portion so that seawater in the ballast tank 110 can be discharged outboard. The seawater jetting port 150 can rapidly discharge the seawater in the ballast tank 110 to float the ship to a predetermined extent. In other words, the seawater jetting port 150 discharges the seawater in the ballast tank 110 outboard, thereby lowering the waterline of the ship by a predetermined degree. This is to prevent the intruder from approaching the ship through the side portion (for example, climbing through the side portion) by raising the ship as much as possible above the water surface.

In the case of the water cannon 130 and the steam injection nozzle 140 described above, the main purpose is to directly or indirectly hurt an external intruder such as a pirate, while in the case of the present seawater jet opening 150, . Therefore, the seawater jetting port 150 can continuously discharge a large amount of seawater overboard, such as the water cannon 130 and the like. As described above, the seawater supply pump 120 can be disposed adjacent to the seawater jetting port 150 at the lower end of the ballast tank 110 to provide sufficient pump pressure to the seawater jetting port 150.

FIG. 2 is a schematic view showing the ship intrusion prevention system of FIG. 1 viewed from the front side.

Referring to FIG. 2, a plurality of the water cannon 130, the steam injection nozzle 140, and the sea water injection opening 150 may be provided. In addition, the plurality of water cannons 130, the steam injection nozzle 140, and the sea water injection port 150 may be disposed along the longitudinal direction of the ship on the side portions, respectively. This arrangement enables the side portion of the ship to be entirely protected by the water cannon 130 or the like.

3 is an operational state diagram of the intrusion prevention system for a ship shown in Fig.

Referring to FIG. 3, the intrusion prevention system 100 for a ship according to the present embodiment will be described. First, when the ship is in the first waterline D1 state, the intruder D2, such as a pirate, Approach. When the approaching intruder D2 is detected, the ship intrusion prevention system 100 according to the present embodiment is driven. The water cannon 130 emits a water cannon or high pressure water downward toward the approaching intruder D2 and the steam injection nozzle 140 injects the steam generated through the heat exchanger 141 to the side portion, Thereby preventing the intruder D2 from clinging to the side portion. At this time, the seawater required for the water cannon 130 and the steam injection nozzle 140 is supplied through the seawater in the ballast tank 110.

Further, the seawater jetting port 150 discharges a large amount of seawater in the ballast tank 110 in the water. The seawater level in the ballast tank 110 is rapidly lowered due to seawater discharge in the ballast tank 110 of the sea water jetting port 150. The seawater consumed in the water cannon 130 or the steam spray nozzle 140 also helps to lower the water level in the ballast tank 110. As the seawater level in the ballast tank 110 is lowered, the ship gradually floats above the water surface, and the waterline of the ship is lowered from the initial first water line D1 to the second waterline D2. Such a rise of the ship increases the freeboard height of the ship side portion, and consequently prevents or at least delays entry of the outer intruder into the upper deck U through clibing or the like.

In addition, the seawater jetting port 150 gradually becomes adjacent to the waterline as the ship floats, and when the seawater is continuously discharged from the seawater jetting port 150 adjacent to the waterline, a kind of vortex can be formed on the front side. This vortex may also have the effect of pushing out the intruder D2 to approach the side and obstruct access to the side of the intruder D2.

As described above, the intrusion prevention system 100 for a ship according to the present embodiment is capable of preventing intrusion of an intruder such as a pirate through various means such as a water cannon 130, a steam injection nozzle 140 and a seawater jetting port 150 Access can be prevented. Particularly, in the intrusion prevention system 100 for a ship according to the present embodiment, seawater in the ballast tank 110 is used in the water cannon 130 or the steam injection nozzle 140, and the seawater is supplied to the ballast tank 110), it is possible to float the ship to a certain level above the water surface, and the height of the freeboard of the ship can be increased to effectively interfere with the entry into the ship through the side portion of the outside intruder.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention as set forth in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
