Problems solved by technology

[0005] However, in this case, the space formed between the outer tank and the inner tank needs to be further insulated, so the pipe fixing structure and fixing work may become complicated
In addition, it is difficult to smoothly close the periphery of the secondary partition wall disposed between the internal cabin body and the primary partition wall, so a leak problem may occur
In addition, the airtight maintaining part leaks out of the outer casing in a state surrounding the pipe protruding upward from the outer casing, so the utilization rate of the surrounding space may be reduced, and leakage may be easily caused by various external impacts.

Abstract

Disclosed are a structure for mounting a pump tower of an LNG storage tank and a manufacturing method thereof. The structure for mounting a pump tower of an LNG storage tank according to one embodiment of the present invention comprises: an adaptor disposed in a predetermined area of an aperture which is formed in an inside hull of an upper portion of the LNG storage tank; and a cover provided with a through hole corresponding to the pipe of a pump tower mounted on the storage tank and disposed in the remaining area of the aperture so as to be connected to the adaptor.

Description

technical field [0001] The invention relates to a pump tower arrangement structure body of a liquefied natural gas storage tank and a manufacturing method thereof. Background technique [0002] The liquefied natural gas (LNG) storage tank of the transport ship stores the liquefied natural gas cooled to about -163°C, so it is made of ultra-low temperature resistant materials, and is composed of a heat-insulating structure that is resistant to thermal stress and thermal shrinkage and can block heat intrusion . The storage tank is sequentially provided with a primary partition wall, an upper heat insulation board, a secondary partition wall and a lower heat insulation board from the inside of the tank to the outside, and is provided in a joint state with an inner hull. [0003] Such a storage tank is provided with a pump tower for loading and unloading liquefied natural gas, and the pump tower is composed of a pipeline structure including a plurality of pipelines. The piping ...
