A riser weak link (10) is described. The riser weak link comprises an upper housing (16) for connecting to a riser upper section (12), a lower housing (18) for connecting to a riser lower section (14), at least one connection device for releasably connecting the upper and lower housings, and a pressure application device (24) adapted to apply a coupling force to the upper housing to at least partially counter a separation force applied, in use, by well pressure, the well pressure separation force acting to separate the upper and lower housings.

L'invention concerne une section à casser (10) pour colonne montante. La section à casser pour colonne montante comporte un carter supérieur (16) pour raccordement à une section supérieure de la colonne montante (12), un carter inférieur (18) pour raccordement à une section inférieure de la colonne montante (14), au moins un dispositif de raccordement pour raccorder de façon amovible les carters inférieur et supérieur et un dispositif d'application de pression (24) destiné à appliquer une force de couplage au carter supérieur pour contrer, au moins partiellement, une force de séparation appliquée, lors de lutilisation, par la pression du puits, la force de séparation due à la pression du puits agissant pour séparer les carters supérieur et inférieur.
