Abstract

Selon la présente invention, un dispositif (3000) de mesure de vibration et un dispositif (3000) de mesure de vibration voisin mesurent des vibrations dans un tubage ou des vibrations propagées depuis un tubage à des moments différents. Un dispositif (2000) d'identification de position de fuite a : une première unité (2010) d'identification de dispositif de mesure qui, lorsque les vibrations mesurées au niveau de l'un des dispositifs (3000) de mesure de vibration indiquent une fuite, identifie le dispositif (3000) de mesure de vibration en tant que premier dispositif de mesure ; une seconde unité (2020) d'identification de dispositif de mesure qui, des dispositifs (3000) de mesure de vibration voisins du premier dispositif de mesure, identifie un dispositif (3000) de mesure de vibration, dont le degré de fuite indiqué par les vibrations mesurées est plus grand, en tant que second dispositif de mesure ; et une unité (2030) d'identification de position qui identifie la position de fuite comme étant entre la position d'installation du premier dispositif de mesure et la position d'installation du second dispositif de mesure.
