Abstract

Procédé de colmatage d'une fuite de gazoduc/oléoduc en eau profonde. Selon ce procédé. Des engrenages (17) qui sont montés sur un bateau (18) et qui sont reliés par des chaînes (11) à des poulies différentielles (5) sont entraînés par un moteur électrique. Les poulies différentielles (5) sont soutenues par un flasque (2), une soupape à bride (26) et un tube en acier (1), ce qui, par application de la force traction desdites poulies, permet d'enfoncer une bouchon de bois dur ou un bouchon de cuivre (24), ou encore un tube en acier-cuivre de forme hémisphérique (27) dans une ouverture d'un tuyau en acier (16) qui fuit ou dans l'ouverture d'un tuyau à collerette (25) pour colmater la fuite sur le tuyau en acier (16), le brut étant en outre recueilli lorsque qu'un tube en acier-cuivre tronconique (27) est utilisé pour le colmatage de la fuite.
