Description

해수의 자연 순환이 가능한 선박Vessels capable of natural circulation of seawater
본 발명은 해수의 자연 순환이 가능한 선박에 관한 것으로, 더욱 상세하게는 액체화물의 적재상태에 따라 평형수를 유입하여 해수의 자연 순환이 가능한 선박에 관한 것이다.The present invention relates to a ship capable of natural circulation of seawater, and more particularly, to a ship capable of natural circulation of seawater by introducing ballast water according to the loading state of liquid cargo.
일반적으로 대형 선박은 상당한 중량의 화물을 적재할 수 있도록 설계되어 있다. 따라서 이러한 대형 선박은 기준 중량 이하의 화물이 적재되거나 화물이 적재되지 않은 상태에서는 수면에 잠기는 깊이(흘수)가 작아지게 된다. 그런데 흘수의 감소는 선박의 좌우 균형 상태를 불안정하게 하고 프로펠러의 수면 노출을 야기하므로 선박의 안정적인 운항과 경제적인 운항을 방해한다.In general, large ships are designed to carry a significant amount of cargo. Therefore, in such a large vessel, the depth (draft) to be submerged in the water surface becomes smaller when cargos of less than the reference weight are loaded or cargoes are not loaded. However, the decrease in draft makes the left and right balance of the ship unstable and causes the propeller to be exposed to the water surface, thereby hindering the stable and economical operation of the ship.
이러한 이유로 대형 선박은 적재되는 화물의 중량에 따라 선박의 부력을 조정할 수 있도록 평형수 처리장치를 구비하고 있다. 평형수 처리장치는 해수(통상적으로 평형수라고 함)를 선박 내부의 평형수 탱크로 유입하거나 또는 평형수 탱크 내부의 해수를 외부로 배출시켜 대형 선박의 흘수를 일정하게 유지시킨다.For this reason, large ships are equipped with ballast water treatment devices to adjust the buoyancy of the ships according to the weight of the loaded cargo. The ballast water treatment device keeps the draft of a large ship constant by introducing seawater (usually called ballast water) into the ballast tank inside the ship or discharging the seawater inside the ballast tank to the outside.
종래의 평형수 처리장치는 수시로 변하는 조건들에 대해서 작업자가 지속적 또는 주기적으로 모니터링해야만 하는 번거로움이 있고, 작업자가 작업하는 조건이 다를 때마다 모니터링 결과에 따라 선박 내에 배치된 평형수 탱크에 얼마의 양만큼 평형수를 공급하거나 배출할지를 결정해서 평형수 탱크와 연결된 펌프 및 밸브를 각각 조절해야하는 불편함이 있었다.The conventional ballast water treatment apparatus has the inconvenience that the operator has to continuously or periodically monitor for frequently changing conditions, and whenever the conditions for the operator to work are different, how much is stored in the ballast water tank disposed in the ship according to the monitoring result? It was inconvenient to have to control the pump and valve connected to the ballast tank by determining whether to supply or discharge the amount of ballast water.

실린더 모듈(415)은 도 3에 도시된 제1 실시 형태로, 중공중량물(410)과 개폐부재(440)를 연결하는 피스톤(420) 및 피스톤(420)을 내부에 수용하는 실린더 케이스(430)를 포함할 수 있다. 이때, 피스톤(420)은 일체형으로 형성되어 중공중량물(410)과 개폐부재(440)를 연결하며, 실린더 케이스(430)의 내부에 수용될 수 있다. 피스톤(420)은 액체화물에 적재상태에 따른 중공중량물(410)의 부유(상하이동)로 인해 개폐부재(440)를 상하 이동시킬 수 있다.The cylinder module 415 is the first embodiment shown in FIG. 3 , and a piston 420 connecting the hollow weight 410 and the opening/closing member 440 and a cylinder case 430 accommodating the piston 420 therein. may include At this time, the piston 420 is integrally formed to connect the hollow weight 410 and the opening and closing member 440 , and may be accommodated in the cylinder case 430 . The piston 420 may move the opening/closing member 440 up and down due to the floating (up and down movement) of the hollow heavy object 410 according to the loading state in the liquid cargo.
또한, 실린더 모듈(415)은 도 4에 도시된 제2 실시 형태로, 중공중량물(410)에 결합된 제1 피스톤 (422) 및 제1 피스톤로드(422a), 개폐부재(440)에 결합된 제2 피스톤(424) 및 제2 피스톤로드 (424a), 제1 피스톤(422) 및 제2 피스톤(424)를 내부에 수용하고, 제1 피스톤(422)와 제2 피스톤(424) 사이 공간을 공기 등의 압축성유체나 유압유 등의 비압축성유체로 된 동력전달물질(450)로 개재하는 실린더 케이스(430)를 포함할 수 있다. 이때, 제1 피스톤(422)은 액체화물에 적재상태에 따라 중공중량물(410)의 상하 이동시 동력전달물질(450)로 개재되는 사이 공간을 가압하여 개폐부재(440)에 결합된 제2 피스톤(424)를 상하 이동시킬 수 있다. 상기와 같이 제2 실시 형태에서는 실린더 케이스(430)의 내부에 동력전달물질(450)이 개재되도록 구성하면 액체화물의 유출을 방지할 수 있다.In addition, the cylinder module 415 is the second embodiment shown in FIG. 4 , the first piston 422 and the first piston rod 422a coupled to the hollow weight 410 , coupled to the opening/closing member 440 . The second piston 424 and the second piston rod 424a, the first piston 422 and the second piston 424 are accommodated therein, and the space between the first piston 422 and the second piston 424 is It may include a cylinder case 430 interposed with a power transmission material 450 made of a compressible fluid such as air or an incompressible fluid such as hydraulic oil. At this time, the first piston 422 presses the space interposed by the power transmission material 450 when the hollow weight 410 moves up and down according to the loading state of the liquid cargo, and the second piston coupled to the opening and closing member 440 ( 424) can be moved up and down. As described above, in the second embodiment, when the power transmission material 450 is interposed inside the cylinder case 430 , it is possible to prevent the liquid cargo from flowing out.
여기서, 중공중량물(410)은 액체화물 적재 시 부력을 생성할 수 있도록 설정된 부피를 가질 수 있다. 또한, 중공중량물(410)은 공창 상태 시 개폐부재(440)와 결합된 제2 피스톤(424)가 생성하는 부력 및 선박 운항 중에 발생하는 해수 동압력에도 해수가 유입될 수 있도록 설정된 중량을 가질 수 있다.Here, the hollow weight 410 may have a volume set to generate buoyancy when loading liquid cargo. In addition, the hollow weight 410 may have a weight set so that seawater can flow in the buoyancy force generated by the second piston 424 coupled to the opening and closing member 440 in the empty state and the seawater dynamic pressure generated during vessel operation. .
개폐부재(440)는 탄성을 가진 고분자 물질, 예컨대 엘라스토머(Elastomer)를 포함할 수 있으며, 상하 이동으로 해수유입구(310)의 개폐를 제어하여 해수 유입을 차단(수밀)하거나, 해수를 유입(비수밀)시킬 수 있다. 예를 들면, 도 3 내지 도 4의 (가)와 같이 화물창(100)에 액체화물을 적재하면 중공중량물(410)은 부력을 생성하고, 부력은 피스톤(420)과 개폐부재(440)를 상부로 올릴 수 있다. 상부로 올라간 개폐부재(440)는 씨체스트(300)와 닿게 되어 해수의 유입을 차단할 수 있다. 이때, 액체화물에 의해 평형수는 충분할 수 있다.The opening/closing member 440 may include a polymer material having elasticity, for example, an elastomer, and control the opening and closing of the seawater inlet 310 by vertical movement to block (watertight) the inflow of seawater, or to introduce (non-tight) seawater. watertight) can be done. For example, when a liquid cargo is loaded in the cargo hold 100 as shown in FIGS. 3 to 4 (A), the hollow weight 410 generates buoyancy, and the buoyancy force is the piston 420 and the opening/closing member 440 on the upper part. can be raised to The opening/closing member 440 raised upward comes into contact with the sea chest 300 to block the inflow of seawater. At this time, the ballast water may be sufficient by the liquid cargo.
또한, 도 3내지 도 4의 (나)와 같이 적재된 액체화물을 하역하면 중공중량물(410)은 부력을 상실하고 중력의 방향으로 자중이 생성되며, 자중은 피스톤(420)과 개폐부재(440)를 중력 방향으로 내리게 되고, 중력방향으로 내려간 개폐부재(440)는 씨체스트(300)와 이격되어 해수가 유입될 수 있다. 유입된 해수에 의해 평형수가 맞춰질 수 있다.In addition, when the loaded liquid cargo is unloaded as shown in FIGS. 3 to 4 (B), the hollow weight 410 loses buoyancy and generates its own weight in the direction of gravity, and its own weight is the piston 420 and the opening and closing member 440 ) is lowered in the direction of gravity, and the opening/closing member 440 descended in the direction of gravity is spaced apart from the sea chest 300 so that seawater can be introduced. Ballast water can be adjusted by the incoming seawater.
또한, 실린더 케이스(430)는 직선형, 곡선형, 절곡형 중 적어도 하나의 형태로 형성되어 화물창(100)에 연결될 수 있다. 실린더 케이스(430)의 형태에 관해서는 도 8 내지 도 11을 참조하여 후술하도록 한다.In addition, the cylinder case 430 may be formed in at least one of a straight shape, a curved shape, and a bent shape to be connected to the cargo hold 100 . The shape of the cylinder case 430 will be described later with reference to FIGS. 8 to 11 .
도 5는 본 발명의 일 실시예에 따른 해수의 자연 순환이 가능한 선박에서 전체 시스템을 설명하기 위해 배관을 함께 나타내는 도면이다.5 is a view showing piping together to explain the entire system in a ship capable of natural circulation of seawater according to an embodiment of the present invention.
도 5를 참조하여 선박에서 해수의 자연 순환 과정을 설명하면, 공창 상태, 해수 자연 유입 상태 및 해수의 자연 순환 상태에 있어서, 우선 ① 공창 상태에서 개폐부재(440)와 씨체스트(300)는 이격되고 해수유입제어장치(400)를 통해 해수가 유입될 수 있다. 해수는 하층 평형수 저장탱크(200)에 선박 중량과 부력이 일치(예컨대, 아르키메데스의 원리)할 때까지 또는 수밀 선측 거더(600)까지 유입될 수 있다. When the natural circulation process of seawater in a ship is described with reference to FIG. 5, in the empty state, the seawater natural inflow state, and the natural circulation state of seawater, first, the opening and closing member 440 and the sea chest 300 are spaced apart in the empty state ① and seawater may be introduced through the seawater inflow control device 400 . Seawater may be introduced into the lower ballast water storage tank 200 until the ship weight and buoyancy match (eg, Archimedes' principle) or until the watertight side girder 600 .
② 하층 평형수 저장탱크(200)에 유입된 해수는 배관(700)을 통해 열교환기를 포함하는 기관실(800)로 이동하여 잡용수(雜用水, 예를 들어 열교환을 위한 냉각수)로 활용될 수 있다. 기관실(800)로 이동한 해수만큼 해수유입제어장치(400)를 통해 선외의 해수가 하층 평형수 저장탱크(200)로 유입될 수 있다. ② The seawater flowing into the lower ballast water storage tank 200 moves to the engine room 800 including the heat exchanger through the pipe 700 and can be used as general water (for example, cooling water for heat exchange). . As much as the seawater that has moved to the engine room 800 , the seawater outboard may be introduced into the lower ballast water storage tank 200 through the seawater inflow control device 400 .
③ 기관실(800)을 통과한 해수는 배관(700)을 통해 상측 평형수 저장탱크(200)로 이동할 수 있다. ③ The seawater that has passed through the engine room 800 may move to the upper ballast water storage tank 200 through the pipe 700 .
④ 상측 평형수 저장탱크(200)에 해수가 계속 채워지고 설정된 압력에 도달하면 일방향 감압 체크밸브(500)가 열리고 해수가 선외로 배출될 수 있다. ④ When seawater continues to fill the upper ballast water storage tank 200 and reaches a set pressure, the one-way pressure reducing check valve 500 opens and seawater can be discharged overboard.
① 부터 ④ 까지는 자연적, 연속적, 지속적으로 이루어질 수 있다. 다만, 해수의 이동 시 경우에 따라 펌프가 필요할 수 있다.① to ④ can be done naturally, continuously and continuously. However, in some cases, a pump may be required for seawater movement.
다음, 화물 적재 상태 및 해수 유입 차단 상태에서는 개폐부재(440)와 씨체스트(300)가 닿게 되어 해수의 유입이 차단되고, ① 부터 ④까지의 배관(700)도 차단(close)될 수 있다. Next, in the cargo loading state and the seawater inflow blocking state, the opening and closing member 440 and the sea chest 300 come into contact to block the inflow of seawater, and the pipe 700 from ① to ④ may also be closed.
또한, ⑤ 기관실의 씨체스트를 통해 해수가 유입되어 잡용수로 활용될 수 있다. ⑥ 잡용수로 활용된 해수는 선외로 배출될 수 있다.In addition, ⑤ seawater flows in through the sea chest of the engine room and can be used as a general water. ⑥ Seawater used for general purpose may be discharged overboard.
도 6 및 도 7은 선박의 크기에 따라 해수유입제어장치의 규격 변경에 대한 적용 예시를 나타내는 도면들로, 해수유입제어장치(400)는 중공중량물(410)의 상단(H) 이상으로 액체화물이 적재되면 해수 유입을 차단하고, 중공중량물(410)의 하단(L) 이하로 액체화물이 하역되면 해수 유입을 시작할 수 있다. 즉, 해수유입제어장치(400)는 중공중량물(410)의 형상 및 실린더 모듈(415)의 길이 중 적어도 하나를 변경하여 액체화물의 적재상태에 따라 해수유입구(310)의 개폐시기를 제어할 수 있다. 6 and 7 are diagrams showing an example of application to change the standard of the seawater inflow control device according to the size of the ship, and the seawater inflow control device 400 is a liquid cargo above the upper end (H) of the hollow heavy object 410 When this is loaded, the inflow of seawater is blocked, and when the liquid cargo is unloaded below the lower end (L) of the hollow weight 410, the inflow of seawater can be started. That is, the seawater inlet control device 400 changes at least one of the shape of the hollow heavy object 410 and the length of the cylinder module 415 to control the opening and closing timing of the seawater inlet 310 according to the loading state of the liquid cargo. have.
여기서, 도 6은 부분 적재가 빈번한 아프라막스(Aframx)급 이하의 원유운반선 또는 화학제품 운반선(PC, Product Carrier)에 적합한 적용 예시이며, 도 7은 주로 만재 상태 또는 공창 상태로 운항하는 아프라막스급 이상(아프라막스, 수에즈막스[Suez max], VLCC 급)의 원유운반선에 적합한 적용 예시이다.Here, FIG. 6 is an application example suitable for crude oil carriers or chemical product carriers (PC, Product Carrier) below the Aframx class, which are frequently partially loaded, and FIG. This is an application example suitable for crude oil carriers of max class or higher (Aframax, Suez max, VLCC class).
도 8 내지 도 11은 본 발명의 일 실시예에 따른 해수유입제어장치를 다양한 곳에 설치하기 위한 구조 변경의 적용 예시를 나타내는 도면들이다.8 to 11 are views showing an example of application of a structural change for installing the seawater inflow control device in various places according to an embodiment of the present invention.
도 8 내지 도 11을 참조하면, 해수유입제어장치(400)는 다양한 곳에 설치하기 위하여 상술한 제2 실시 형태와 같이 내부에 동력전달물질(450)이 개재된 실린더 케이스(430)를 포함할 수 있다.8 to 11 , the seawater inflow control device 400 may include a cylinder case 430 having a power transmission material 450 interposed therein as in the second embodiment described above for installation in various places. have.
여기서, 씨체스트(300)는 선체의 측면 또는 저면에 배치되어 해수유입구(310)의 개구방향이 측방 또는 상방으로 형성될 수 있다.Here, the sea chest 300 may be disposed on the side or bottom of the hull so that the opening direction of the seawater inlet 310 may be lateral or upward.
또한, 실린더 모듈(415)은 해수유입구(310)의 개구방향에 따라 개폐부재(440)가 해수유입구(310)를 개폐하도록 실린더 케이스(430)의 형태, 중공중량물(410)의 이동방향 및 개폐부재(440)의 이동방향 중 적어도 하나가 설정될 수 있다.In addition, the cylinder module 415 has the shape of the cylinder case 430, the moving direction and opening and closing of the hollow weight 410 so that the opening and closing member 440 opens and closes the seawater inlet 310 according to the opening direction of the seawater inlet 310. At least one of the moving directions of the member 440 may be set.
예를 들면, 도 8과 같이 실린더 케이스(430)를 이중저(내저판, 선저외판)에 설치한 경우, 실린더 케이스(430)가 직선형으로 형성되어 상하 이동하는 중공중량물(410)이 생성하는 수직 방향의 힘이 개폐부재(440)를 상하 이동하도록 만드므로 중공중량물(410) 및 개폐부재(440)가 모두 상하 이동할 수 있다. For example, when the cylinder case 430 is installed on a double bottom (inner bottom plate, ship bottom outer plate) as shown in FIG. 8 , the cylinder case 430 is formed in a straight line and the vertical movement of the hollow heavy object 410 is generated. Since the directional force causes the opening and closing member 440 to move up and down, both the hollow weight 410 and the opening and closing member 440 can move up and down.
또한, 도 9과 같이 실린더 케이스(430)를 선측에 설치한 경우, 실린더 케이스(430)가 절곡형으로 형성되어 중공중량물(410)은 상하 이동하고, 개폐부재(440)는 좌우 이동할 수 있다.In addition, when the cylinder case 430 is installed on the ship side as shown in FIG. 9 , the cylinder case 430 is formed in a bent shape so that the hollow weight 410 moves up and down, and the opening and closing member 440 can move left and right.
다만, 도 8의 실린더 케이스(430)의 (M) 위치 및 도 9의 실린더 케이스(430)의 (M) 위치는 용접 구조로 용접 결합(크랙 등)에 의한 누유 가능성이 존재할 수 있으므로, 도 10 및 도 11에 도시된 바와 같이 실린더 케이스(430)의 (N) 위치는 위치 변경으로 누유 가능성이 매우 낮아질 수 있다.However, since the (M) position of the cylinder case 430 of FIG. 8 and the (M) position of the cylinder case 430 of FIG. 9 have a welded structure, there may be a possibility of leakage due to welding (cracks, etc.), And the (N) position of the cylinder case 430 as shown in Figure 11 can be very low possibility of leakage due to a change in position.
도 10 및 도 11에서는 실린더 케이스(430)를 절곡형 형태로 형성하고, 화물창(100)에 결합되는 실린더 케이스(430)의 위치를 변경하여 중공중량물(410)은 상하 이동하고, 개폐부재(440)는 좌우 이동할 수 있다. 이때, 씨체스트(300)의 해수유입구(310)의 개구 방향이 측방으로 형성되어 개폐부재(440)의 이동에 따라 개폐가 제어될 수 있다.In FIGS. 10 and 11 , the cylinder case 430 is formed in a bent shape, and the position of the cylinder case 430 coupled to the cargo hold 100 is changed so that the hollow weight 410 moves up and down, and the opening and closing member 440 ) can be moved left and right. At this time, the opening direction of the seawater inlet 310 of the sea chest 300 is formed to the side, so that opening and closing can be controlled according to the movement of the opening and closing member 440 .
도 10에서는 화물창(100)에 액체화물이 적재된 경우 중공중량물(410)이 부력에 의해 위로 올라가면서 개폐부재(440)가 우측으로 이동하여 해수가 유입되지 않도록 씨체스트(300)의 해수유입구(310)를 밀폐할 수 있다.In FIG. 10, when a liquid cargo is loaded in the cargo hold 100, the sea chest 300 moves to the right so that the sea water does not flow by moving the opening and closing member 440 to the right as the hollow weight 410 rises by buoyancy. 310) can be sealed.
