ＬＮＧ 펌프타워의 파이프 설치 구조{STRUCTURE FOR INSTALLING A PIPE OF A LNG PUMP TOWER}Pipe installation structure of the LN pump tower {STRUCTURE FOR INSTALLING A PIPE OF A LNG PUMP TOWER}

본 발명은 LNG 펌프타워의 파이프 설치 구조에 관한 것으로서, 보다 상세하게는 트렁크 데크와 이에 관통하여 설치된 파이프간의 기밀을 유지하도록 함과 아울러 파이프가 운동에 의해 손상되는 것을 방지하고, 설치 후 유지 및 보수를 위한 수리나 교체 등을 용이하도록 하는 LNG 펌프타워의 파이프 설치 구조에 관한 것이다.The present invention relates to a pipe installation structure of the LNG pump tower, and more particularly, to maintain the airtight between the trunk deck and the pipe installed therethrough, and to prevent the pipe from being damaged by the movement, maintenance and repair after installation It relates to a pipe installation structure of the LNG pump tower to facilitate the repair or replacement for.

일반적으로, 액화천연가스(liquefied natural gas, 이하 "LNG"라 함)는 메탄을 주성분으로 하는 천연가스를 대략 -163℃의 초저온 상태로 냉각하여 그 부피를 대략 1/600 정도로 감소시킨 것으로서, 이로 인해 천연가스의 수송 및 저장에 유리하도록 한다.In general, liquefied natural gas (hereinafter referred to as "LNG") is a natural gas mainly composed of methane is cooled to an extremely low temperature of about -163 ℃ to reduce the volume of about 1/600, so This is advantageous for the transportation and storage of natural gas.

이러한 LNG를 에너지원으로 사용하기 위해서는 LNG 생산기지로부터 수요지까지대량으로 이송하기 위해서 LNG 운반선이 필요하게 되었는데, LNG 운반선은 천연가스의 생산지인 로딩(loading) 항구에서 기체 상태인 천연가스를 초저온 상태로 액화시켜 카고 탱크(cargo tank)에 저장함과 아울러 언로딩(unloading) 항구에 도 착한 후에는 초저온의 LNG를 기화시켜서 천연가스로 변환시킨 후, 이를 배관 등을 통해 수요지 내지 수요자에게 공급하게 된다.In order to use such LNG as an energy source, LNG carriers are needed to transport large quantities from LNG production bases to demand sites. LNG carriers use gaseous natural gas at ultra low temperatures in a loading port, which is a natural gas production site. After liquefying and storing in cargo tanks and arriving at unloading ports, cryogenic LNG is vaporized and converted to natural gas, which is then supplied to customers or consumers through piping.

이와 같은 LNG 운반선은 카고 탱크에 LNG의 적재 및 하역을 위하여 펌프타워(pump tower)가 설치되는데, 이러한 LNG 펌프타워는 화물인 LNG로 인해 극저온에서 운용하게 되므로, 심한 온도차에 의한 열응력이 발생할 수 있기 때문에 설치시 많은 주의와 검토가 요구된다. Such LNG carriers are equipped with a pump tower for loading and unloading LNG in cargo tanks. Since these LNG pump towers are operated at very low temperatures due to cargo, LNG, thermal stress may occur due to severe temperature differences. This requires a lot of care and review during installation.

종래에서 LNG 운반선에 구비되는 LNG 펌프타워의 설치 구조를 첨부된 도면을 참조하여 설명하면 다음과 같다. Referring to the attached structure of the LNG pump tower provided in the LNG carrier in the prior art as follows.

도 1은 종래의 기술에 따른 LNG 펌프타워의 파이프 설치 구조를 도시한 단면도이다. 종래의 기술에 따른 LNG 펌프타워의 파이프 설치 구조는 카고 탱크의 LNG를 적재 또는 하역시키기 위한 LNG 펌프타워의 파이프(pipe; 1)가 트렁크 데크(trunk deck; 2)를 관통하도록 설치되고, 파이프(1)의 외측에 SUS 재질의 익스펜션 벨로우즈(expansion bellows; 3)가 삽입되며, 익스펜션 벨로우즈(3)의 양측을 파이프(1)와 트렁크 데크(2)에 각각 용접함으로써 용접부(4)가 형성된다. 1 is a cross-sectional view showing a pipe installation structure of the LNG pump tower according to the prior art. The pipe installation structure of the LNG pump tower according to the prior art is installed so that the pipe (1) of the LNG pump tower for loading or unloading the LNG of the cargo tank passes through the trunk deck (2). SUS expansion bellows 3 are inserted into the outside of the 1), and welds 4 are formed by welding both sides of the expansion bellows 3 to the pipe 1 and the trunk deck 2, respectively. do.

이와 같은 종래의 기술에 따른 LNG 펌프타워의 파이프 설치 구조는 용접부(4)에 의해 트렁크 데크(2)와 파이프(1)의 결합부위를 통해서 LNG가 유출되는 것을 방지하고, 익스펜션 벨로우즈(3)에 의해 파이프(1)가 자신의 운동에 의해 손상되지 않도록 한다.The pipe installation structure of the LNG pump tower according to the related art prevents the LNG from flowing out through the coupling portion of the trunk deck 2 and the pipe 1 by the welding portion 4, and the expansion bellows 3 This prevents the pipe 1 from being damaged by its movement.

Expensive expansion bellows mentioned in GTT (Gaz Transport & Technigaz) are applied to prevent the trunk deck from being damaged.This is because the expansion bellows are made of SUS material, which is easy to cause corrosion at sea. After installation of the bellows, the LNG tanks should be removed from the cargo tank to maintain and repair them, then after inerting and aeration, the expansion bellows and pipe should be replaced by a welder to replace the expansion bellows. It caused difficulties.

또한, 자켓인슐레이션(120)이 기밀유지부(130)에 의해 파이프(10)의 돌출부(11)와 트렁크 데크(20)의 지지부(21)에 대하여 물이나 그 밖의 유체 등이 누출되지 않도록 기밀이 유지될 수 있으며, 기밀유지부(130)가 실리콘 본딩(silicon bonding)에 의해 형성됨으로써 자켓인슐레이션(120)의 일측과 파이프(10) 사이, 그리고 자켓인슐레이션(120)의 다른 일측과 트렁크 데크(20) 사이의 기밀작업이용이해진다.In addition, the jacket insulation 120 is airtight so that water or other fluids do not leak to the protrusion 11 of the pipe 10 and the support part 21 of the trunk deck 20 by the airtight holding part 130. The airtight portion 130 is formed by silicon bonding so that one side of the jacket insulation 120 and the pipe 10, and the other side of the jacket insulation 120 and the trunk deck 20 can be maintained. The confidential work between) becomes available.
