Title (EN) FLOATING STRUCTURE FOR PRODUCING LNG AND MAINTENANCE METHOD OF LNG TANK IN THE FLOATING STRUCTURE
(FR) STRUCTURE FLOTTANTE POUR LA PRODUCTION DE GNL ET PROCÉDÉ DE MAINTENANCE DE RÉSERVOIR DE GNL DANS LA STRUCTURE FLOTTANTE
Abstract:
(EN) Provided is a floating structure that is capable of supplying a hydrocarbon gas to an LNG tank during a maintenance work for the LNG tank by utilizing essential facility for LNG production. A floating structure (1) having a dehydration system (11), a liquefaction system (3), an LNG tank (4), a BOG compressor (66), a first line (101) for connecting a downstream portion of the dehydration system with the LNG tank to supply the natural gas from which moisture has been removed to the LNG tank, and a second line (102) connecting the BOG compressor with the LNG tank to supply the compressed BOG to the LNG tank.
(FR) La présente invention concerne une structure flottante apte à fournir un gaz hydrocarboné à un réservoir de GNL pendant des travaux de maintenance dudit réservoir de GNL en utilisant une installation essentielle pour la production de GNL. Une structure flottante (1) comprend un système de déshydratation (11), un système de liquéfaction (3), un réservoir de GNL (4), un compresseur de BOG (66), une première conduite (101) qui relie une partie aval du système de déshydratation au réservoir de GNL pour acheminer le gaz naturel dont l'humidité a été retirée vers le réservoir de GNL et une seconde conduite (102) qui relie le compresseur de BOG au réservoir de GNL afin d'acheminer le BOG comprimé vers le réservoir de GNL.
