Description

ＬＮＧ선 펌프타워의 지지대 연결 구조{The Connection Structure of a Base-Support of a Pump Tower on a LNG Ship}The Connection Structure of a Base-Support of a Pump Tower on a LNG Ship}

본 고안은 멤브레인 타입 LNG선의 리퀴드 돔의 내부공간에 펌프타워를 설치하기 위한 지지대(base-support)의 연결구조에 관한 것으로, 더욱 상세하게는 펌프타워의 하부 베이스 플레이트에 구비된 체결부와 리퀴드돔의 바닥면에 구비된 지지대 사이에 위치조정용 소켓부를 설치하여 펌프타워 하부의 체결부와 지지대 상부 연결부의 위치가 일치하지 않을 때 발생하는 설치 오차를 조절할 수 있도록 함으로써, 펌프타워의 설치를 용이하게 하고 이에 따라 작업의 능률을 향상시킬 수 있도록 하는 LNG선 펌프타워의 받침대 연결 구조에 관한 것이다.The present invention relates to a connection structure of a base-support for installing a pump tower in an internal space of a liquid dome of a membrane type LNG carrier, and more particularly, a fastening part and a liquid dome provided in a lower base plate of a pump tower. By installing the socket for position adjustment between the supports provided on the bottom surface of the pump to adjust the installation error occurs when the position of the fastening portion of the lower part of the pump tower and the upper connection portion of the support, to facilitate the installation of the pump tower Accordingly, the present invention relates to a pedestal connection structure of an LNG carrier pump tower to improve work efficiency.

일반적으로 종래 멤브레인(Membrane) 타입의 뤼퀴드 돔을 적용한 LNG 운반선에는 LNG를 선적하거나 배출하기 위해 리퀴드 돔 내부에 파이프 구조물인 펌프 타워(Pump tower)가 설치된다. 상기 펌프 타워는 각종 배관류와 LNG 카고 펌프(Cargo Pump)를 지지하는 동시에 파이프를 통해 LNG를 배출하는 배관으로도 사용된다.In general, a LNG carrier that employs a conventional membrane type liquid liquid dome is provided with a pump tower that is a pipe structure inside the liquid dome for loading or discharging LNG. The pump tower is also used as a pipe for discharging LNG through the pipe while supporting various pipes and LNG cargo pump (Cargo Pump).

상기와 같은 펌프 타워의 설치과정을 보면 도 1의 (a)와 같이 펌프타워의 탑재 이전에 지지대(나)를 우선 설치하고 단열방벽 작업이 이루어진다. Looking at the installation process of the pump tower as described above, as shown in Figure 1 (a) prior to the installation of the pump tower (b) is installed first and the insulation barrier work is made.

그 후 제작된 펌프타워(가)를 도 1의 (b)에 도시되어 있는 바와 같이 리퀴드 돔 에리어를 통해 지지대(나)와 펌퍼타워(가)의 하부(다)를 결합시키게 된다.After that, as shown in (b) of FIG. 1, the manufactured pump tower (a) is coupled to the support (b) and the lower part (c) of the pump tower (a) through the liquid dome area.

이 경우 선박이 안벽(quay wall)상태에서 호깅(hogging)상태와 같은 헐 거어더(hull girder) 하중이 생기게 되어 지지대와 펌프타워의 결합부가 도 1의 (c)에서와 같이 일치되지 않는 경우가 많이 발생하게 되며 강제적으로 펌프타워를 받침대에 결합시키면 펌프타워 상부와 데크 연결부에 응력이 생기게 된다. 따라서 하중을 받지 않는 인택트(intact) 상태에서 초기 응력을 갖게 되므로 안전 여유치가 줄어들게 된다.In this case, a hull girder load such as a hogging state is generated in a quay wall state, and the coupling portion of the support and the pump tower does not match as shown in FIG. Forcing the pump tower to the pedestal causes a lot of stress on the top of the tower and the deck connection. Therefore, since the initial stress in the intact (intact) state that is not loaded, the safety margin is reduced.
