Abstract

La présente invention porte sur un système de surveillance de la sécurité d'un système de récupération de gaz d'évaporation (BOG) d'une centrale électrique au GNL flottante. Plus précisément, la présente invention porte sur un système de surveillance d'un système de récupération de BOG, qui reçoit des informations de position (comportement) d'une plateforme en mer mesurées par l'intermédiaire d'un DGPS, des informations sur le gaz, la pression, la direction du vent et la vitesse du vent (ci-après désignées collectivement « informations de mesure ») à partir de dispositifs de site antidéflagrants recevant les informations de mesure mesurées par l'intermédiaire de dispositifs de mesure respectifs (S) pour délivrer en sortie des informations de visualisation 2D sous une forme graphique et des informations de visualisation 3D affichant les informations de mesure sur la base d'une modélisation, permettant ainsi à un utilisateur d'effectuer une analyse. Le système de surveillance peut prévenir des erreurs dues à la transmission et à la réception d'informations avant l'affichage des informations de mesure, filtrer les informations de mesure pour une surveillance de sécurité, permettre au système de récupération de BOG de fonctionner sur la base d'un scénario de maintenance du système de récupération de BOG, et fournir une réalité virtuelle (VR) sur la base du scénario de maintenance et des informations de visualisation 3D, ce qui permet une expérience directe des informations de mesure en réalité virtuelle en fonction d'une situation actuelle du système de récupération de BOG.
