Abstract
A nitrogen compression system for a leakage test on a gas pipeline used for an engine according to the present invention includes: a nitrogen generator which is installed on a hull and generates nitrogen; a nitrogen storage tank which stores the nitrogen generated from the nitrogen generator; an air compressor which generates compressed air used to support starting of an engine for propelling the hull and supplies the compressed air to the engine; an air supplier which supplies air to the air compressor; and a first diverter valve which is installed on a first diverter pipeline connecting the air supplier, the nitrogen storage tank, and the air compressor and is controlled to supply any one of air and nitrogen to the air compressor. When the first diverter valve is controlled to supply nitrogen to the air compressor, compressed nitrogen compressed by the air compressor is used to purge a gas pipeline connected to the engine.
