Referring to FIG. 1, a pipe structure 1 of a pump tower is connected to a loading device and connected to an unloading device P1 for introducing liquefied natural gas into a cargo hold, Discharge pipes P2 and P3 for discharging natural gas, an emergency pipe P4 used in an emergency and a connecting member 4 for connecting these pipes P1 to P4 to each other do. The pipe structure 1 of the pump tower can be manufactured in a truss structure.

펌프타워의 파이프구조물(1)에는 화물창 내 액화천연가스(액체화물)의 운동주기와 외부 파랑하중의 운동주기가 일치하여 발생하는 슬로싱 하중, 외부 파랑하중으로 인해 선체가 운동하여 발생하는 관성력이 작용한다. 또 선체의 온도를 대략 20℃라고 가정할 때, -163℃와 20℃간의 온도 차에 의해 펌프타워의 최상단 파이프구조물(1)에는 큰 인장력이 작용한다.The pipe structure of the pump tower (1) has sloshing load, which is caused by the coincidence of the motion cycle of the liquefied natural gas (liquid cargo) in the cargo hold and the external wave load, and the inertial force generated by the movement of the hull due to the external wave load . Further, assuming that the temperature of the hull is approximately 20 ° C, a large tension force acts on the uppermost pipe structure 1 of the pump tower due to the temperature difference between -163 ° C and 20 ° C.

The pump tower is typically installed close to the bulkhead of the stern side and is supported by a base support (not shown) provided on the inner bottom of the cargo hold in a fixed state in a liquid dome (not shown) do. Here, the discharge pipes P2 and P3 are disposed closer to the inner wall 2 of the heat insulating barrier formed on the side of the partition wall than the emergency pipe P4.

이때, 2개의 방출파이프(P2,P3)와 1개의 응급파이프(P4)는 삼각형 형태로 비교적 안정되게 배치된 반면, 응급파이프(P4) 바깥쪽 옆에 배치된 충전파이프(P1)는 다른 파이프(P2~P4)보다 더 큰 슬로싱 하중(sloshing load)을 받을 수 있다. 이는, 펌프타워의 구조적 안정성에 영향을 미칠 수 있다. 이와 관련하여, 한국공개특허 제2012-0013255호(2012.02.14 공개)는 펌프타워의 파이프 연결구조에 대한 기술을 공개한 바 있다.At this time, the two discharge pipes P2 and P3 and one emergency pipe P4 are relatively stably arranged in the form of a triangle, while the charging pipe P1 disposed beside the emergency pipe P4 is disposed in the other pipe P2-P4). ≪ / RTI > This can affect the structural stability of the pump tower.

The present invention is not limited to the embodiments described below, but may be embodied in other forms. In order to clearly explain the present invention, parts not related to the description are omitted from the drawings, and the width, length, thickness, etc. of the components may be exaggerated for convenience. Like reference numerals designate like elements throughout the specification.

도 2와 도 3을 참조하면, 본 발명의 실시 예에 따른 펌프타워의 파이프구조물(100)은 화물창 내부로 액화천연가스를 유입시키기 위한 충전파이프(101)와, 화물창 외부로 액화천연가스를 유출시키기 위한 방출파이프(102,103), 비상시에 사용되는 응급파이프(104), 조인트부재(120) 및 각 파이프(101~103)를 서로 연결시키는 연결부재(130)를 포함한다.2 and 3, a pipe structure 100 of a pump tower according to an embodiment of the present invention includes a charging pipe 101 for introducing liquefied natural gas into a cargo hold, The emergency pipe 104 used in an emergency, the joint member 120 and the connecting member 130 connecting the pipes 101 to 103 to each other.

충전파이프(101)는 방출파이프(102,103) 사이에 배치되고, 외면에 돌출부(101a)를 형성한다. 충전파이프(101)는 방출파이프(102,103) 사이에 방출파이프(102,103)와 나란히 배치될 수 있다. 충전파이프(101)의 돌출부(101a)는 충전파이프(101)의 길이 방향으로 일정 간격을 두고 형성될 수 있다.The charging pipe 101 is disposed between the discharge pipes 102 and 103 and forms a protrusion 101a on the outer surface. The charging pipe 101 may be disposed side by side with the discharge pipes 102, 103 between the discharge pipes 102, 103. The projection 101a of the filling pipe 101 may be formed at regular intervals in the longitudinal direction of the filling pipe 101. [

펌프타워는 통상적으로 선미 쪽의 격벽에 가깝게 설치되고, 리퀴드돔 (미도시)에 고정된 상태에서 화물창 내측 바닥에 마련된 베이스서포트(미도시)에 의해 지지된다. 여기서, 방출파이프(102,103)는 응급파이프(104)에 비해 격벽 쪽에 형성된 단열방벽의 내벽(2)에 가깝게 배치된다. The pump tower is usually installed close to a stern side partition and is supported by a base support (not shown) provided on the bottom of the cargo hold in a state of being fixed to a liquid dome (not shown). Here, the discharge pipes 102 and 103 are disposed closer to the inner wall 2 of the heat insulating barrier formed on the side of the partition wall than the emergency pipe 104.

이때 충전파이프(101)가 방출파이프(102,103) 사이에 배치됨으로써, 슬로싱 하중을 비롯한 외력으로부터 받는 충격을 감소시킬 수 있다. 이는 충전파이프(101) 양쪽에 배치된 방출파이프(102,103)가 슬로싱 하중(sloshing load)을 어느 정도 방어하여 감소시키기 때문이다. 또, 응급파이프(104)와 단열방벽의 내벽(2)이 충전파이프(101)의 전후 방향의 슬로싱 하중을 방어하여 감소시키기 때문이다.At this time, the charging pipe 101 is disposed between the discharge pipes 102 and 103, thereby reducing the impact from an external force including a sloshing load. This is because the discharge pipes 102 and 103 disposed on both sides of the charging pipe 101 reduce and prevent some degree of sloshing load. This is because the emergency pipe 104 and the inner wall 2 of the heat insulating barrier reduce the sloshing load in the longitudinal direction of the filling pipe 101 and reduce it.

이러한 충전파이프(101), 방출파이프(102,103) 및 응급파이프(104)의 배치구조는 각 파이프(101~104)의 중심점(C1~C4)을 연결할 경우, 삼각형 형상의 영역(S)을 형성하는 구조일 수 있다.The arrangement structure of the charging pipe 101, the discharge pipes 102 and 103 and the emergency pipe 104 forms the triangular region S when connecting the center points C1 to C4 of the pipes 101 to 104 Structure.

도 3과 도 4를 참조하면, 조인트부재(120)는 공동부(120a)와 공동부(120a)로부터 연장 형성된 복수의 삽입관(121~123)을 포함한다. 조인트부재(120)는 충전파이프(101)가 방출파이프(102,103) 사이에 나란하게 배치되고, 파이프구조물(100)의 안정성을 높이기 위해 상술한 삼각형 형상의 영역(S) 내측에 배치될 수 있다.3 and 4, the joint member 120 includes a cavity portion 120a and a plurality of insertion tubes 121 to 123 extending from the cavity portion 120a. The joint member 120 may be disposed inside the triangular region S described above in order to enhance the stability of the pipe structure 100 and the fill pipe 101 is disposed between the discharge pipes 102 and 103 in parallel.

복수의 삽입관(121~123)은 충전파이프(101)의 돌출부(101a)가 삽입되는 제1삽입관(121)과, 방출파이프(102,103)에 연결된 각 연결부재(131,132)의 단부가 삽입되는 제2삽입관(122) 및 제3삽입관(123)을 포함한다. 이때, 도 4에 도시한 바와 같이, 돌출부(101a)가 제1삽입관(121)에 삽입된 상태에서 충전파이프(101)가 방출파이프(102,103) 사이에 나란하게 배치되도록 제2삽입관(122)과 제3삽입관(123)은 공동부(120a)로부터 일정 각도(θ)로 꺾이도록 형성될 수 있다.The plurality of insertion tubes 121 to 123 are inserted into the first insertion tube 121 into which the protrusion 101a of the filling pipe 101 is inserted and the ends of the connecting members 131 and 132 connected to the discharge pipes 102 and 103 A second insertion tube 122 and a third insertion tube 123. At this time, as shown in Fig. 4, the second insertion tube 122 (not shown) is arranged so that the filling pipe 101 is arranged between the discharge pipes 102 and 103 in a state where the projection 101a is inserted into the first insertion tube 121 And the third insertion tube 123 may be formed to be bent at a certain angle? From the cavity 120a.

또, 돌출부(101a)가 방출파이프(102,103)에 연결된 각 연결부재(131,132)의 직경보다 크게 형성된 경우, 그에 대응되게 제1삽입관(121)의 직경(D1)은 제2삽입관(122) 및 제3삽입관(123)의 직경(D2,D3)보다 크게 형성될 수 있다.The diameter D1 of the first insertion tube 121 corresponds to the diameter of the second insertion tube 122 when the protrusion 101a is formed larger than the diameter of each of the connection members 131 and 132 connected to the discharge pipes 102 and 103. [ And the diameters D2 and D3 of the third insertion tube 123, as shown in FIG.

종래에는 통상적으로 충전파이프가 방출파이프에 용접 접합되는 방식으로 직접 연결되었다. 반면, 본 발명의 실시 예에서는 조인트부재(120)를 통해 충전파이프(101)가 방출파이프(102,103)에 간접적으로 연결됨으로써 슬로싱 하중에 대해 유연하게 대응할 수 있다. 이는 결과적으로 펌프타워의 구조적 안전성을 향상시킬 수 있다. 방출파이프(102,103)와 응급파이프(104)는 도2와 도 3에 도시한 바와 같이 해당 연결부재(133,134)에 의해 직접 연결될 수 이다.Conventionally, the fill pipe is typically directly connected in such a way that it is welded to the discharge pipe. On the other hand, in the embodiment of the present invention, the charging pipe 101 is indirectly connected to the discharge pipes 102 and 103 through the joint member 120, so that it can flexibly cope with the sloshing load. As a result, the structural stability of the pump tower can be improved. The discharge pipes 102 and 103 and the emergency pipe 104 can be directly connected by the connecting members 133 and 134 as shown in FIGS.
