LNGC SAFETY APPARATUS OF LNGC UNLOADING SYSTEM

摘要

The present invention relates to an LNGC unloading system, and to a safety device for preventing explosion by cold natural gas (Cold NG) or LNG remaining in a vapor line after unloading is completed in the LNGC unloading system. The safety device of the LNGC (Liquefied Natural Gas Carrier) unloading system of the present invention is the vaporization and expansion of cold natural gas (Cold NG) or LNG remaining in the vapor line after the unloading of LNG is completed. In order to prevent the vapor line from exploding due to this, it operates to discharge natural gas to an LNG cargo tank of LNGC.
