A nitrogen pressurization system for leak testing of gas pipes for an engine according to the present invention comprises: a nitrogen generator (100) that is installed on a hull (S) and generates nitrogen; a nitrogen storage tank (200) for storing the nitrogen generated by the nitrogen generator (100); an air compressor (300) that generates compressed air to assist in the starting of an engine (E) for propelling the hull (S) and supplies the compressed air to the engine (E); an air supply unit (400) for supplying air to the air compressor (300); and a first switching valve (DV1) which is installed on a first switching pipe (DL1) connecting the air supply unit (400), the nitrogen storage tank (200), and the air compressor (300), and is controlled to supply air or nitrogen to the air compressor (300). When nitrogen is supplied to the air compressor (300) by controlling the first switching valve (DV1), a gas pipe (GL) connected to the engine (E) is purged using compressed nitrogen pressurized by the air compressor (300). Selon la présente invention, un système de mise sous pression d'azote destiné à un essai d'étanchéité de tuyaux de gaz pour un moteur comprend : un générateur d'azote (100) qui est installé sur une coque (S) et génère de l'azote ; un réservoir de stockage d'azote (200) permettant de stocker l'azote généré par le générateur d'azote (100) ; un compresseur d'air (300) qui génère de l'air comprimé pour aider au démarrage d'un moteur (E) afin de propulser la coque (S) et alimente le moteur (E) en air comprimé ; une unité d'alimentation en air (400) permettant d'alimenter en air le compresseur d'air (300) ; et une première vanne de commutation (DV1) qui est installée sur un premier tuyau de commutation (DL1) reliant l'unité d'alimentation en air (400), le réservoir de stockage d'azote (200) et le compresseur d'air (300), et est commandée pour alimenter en air ou en azote le compresseur d'air (300). Lorsque le compresseur d'air (300) est alimenté en azote par commande de la première vanne de commutation (DV1), un tuyau de gaz (GL) relié au moteur (E) est purgé à l'aide d'azote comprimé mis sous pression par le compresseur d'air (300). 본 발명에 따른 엔진용 가스 배관의 누설 테스트용 질소의 가압 시스템은 선체(S)에 설치되며 질소를 생성하는 질소 생성기(100), 질소 생성기(100)에서 생성된 질소를 저장하는 질소 저장 탱크(200), 선체(S)를 추진하는 엔진(E)의 시동을 돕는 압축 에어를 생성하여 엔진(E)에 공급하는 에어 컴프레서(300), 에어 컴프레서(300)에 에어를 공급하는 에어 공급부(400), 에어 공급부(400)와 질소 저장 탱크(200)와 에어 컴프레서(300)를 연결하는 제1 전환 배관(DL1) 상에 설치되며, 에어 컴프레서(300)에 에어 또는 질소를 공급하도록 조절하는 제1 전환 밸브(DV1)를 포함하고, 제1 전환 밸브(DV1)를 조절하여 에어 컴프레서(300)에 질소가 공급되는 경우, 에어 컴프레서(300)에 의해 가압된 압축 질소를 이용하여 엔진(E)에 연결된 가스 배관(GL)을 퍼징하도록 구성된다.
