LNG LNG AIR VENTILATION SYSTEM IN DOUBLE WALL PIPE FOR SUPPLYING LNG AND THE LNG SHIP COMPRISING THE SAME

摘要

The present invention relates to an air circulation system in a double piping for LNG transfer, which is configured to supply LNG to a gas consuming place using LNG stored in an LNG handling vessel as fuel, and to supply the combustion air generated from the engine provided in the LNG handling vessel to a space between the inner pipe and the outer pipe of the double piping for LNG transfer formed in a double structure of the inner pipe and the outer pipe, thereby circulating the combustion air in a space between the inner pipe and the outer pipe of the double piping. Accordingly, the present invention is able to reduce the load of a fan applied for air circulation in the double piping and prolong a service life of the pipe.
