Title (EN) MARINE SUCTION ANCHOR
(FR) ANCRE MARINE À ASPIRATION
Abstract:
(EN) A suction anchor is provided that comprises a suction chamber bounded by: (i) a circumferential outer wall, (ii) an upper wall having a central opening, and (iii) the wall of an internal housing; the internal housing defining a passage in communication with the central opening for receiving wellhead components that may be secured to the suction anchor; the suction chamber having a minor upper portion and a major lower portion; the minor upper portion comprising internal reinforcing members extending along the inside of the upper wall from the outer walls to the internal housing; the major portion being adapted to be embedded in a seabed and the minor portion being adapted to project from the seabed when the anchor is installed; wherein the reinforcing members serve both to reinforce the upper wall of the chamber against collapse and to rigidly support the internal housing such that it may resist forces applied to it arising from bending moments applied to a wellhead components received and secured therein. A method of installing the suction anchor is also provided.
(FR) L'invention concerne une ancre à aspiration qui comprend une chambre d'aspiration délimitée par: (i) une paroi externe circonférentielle, (ii) une paroi supérieure ayant une ouverture centrale, et (iii) la paroi d'un logement interne; le logement interne définissant un passage en communication avec l'ouverture centrale pour recevoir des composants de tête de puits qui peuvent être fixés à l'ancre à aspiration; la chambre d'aspiration ayant une partie supérieure secondaire et une partie inférieure principale; la partie supérieure secondaire comprenant des éléments de renforcement internes s'étendant le long de l'intérieur de la paroi supérieure depuis les parois externes vers le logement interne; la partie principale étant conçue pour être incorporée dans un fond marin et la partie secondaire étant conçue pour faire saillie depuis le fond marin lorsque l'ancre est installée; les éléments de renforcement servant à la fois à renforcer la paroi supérieure de la chambre contre l'affaissement et à supporter de manière rigide le logement interne de telle sorte qu'il peut résister à des forces appliquées à celui-ci résultant de moments de flexion appliqués à des composants de tête de puits reçus et fixés à l'intérieur de celui-ci. L'invention concerne également un procédé d'installation de l'ancre à aspiration.
