METHOD FOR INSTALLING COUPLER BASE OF LNG LINE

摘要

PURPOSE: A method for installing a coupler base of an LNG(Liquefied Natural Gas) line is provided to secure the holding of linearness and width of the coupler base and to prevent burn damage by installing the coupler base in advance. CONSTITUTION: A method for installing a coupler base(33) of an LNG line is composed of steps of performing a full pre-erection on a bottom block(30); marking a reference line by temporarily setting an advanced block(31) to the bottom block in a longitudinal direction; mounting the coupler base to the bottom block; separating the bottom block from the block and coating the bottom block; and erecting and provisionally jointing the block at a dock.
