Title (EN) A DEVICE IN CONNECTION WITH HEAVE COMPENSATION
(FR) DISPOSITIF ASSOCIE A LA COMPENSATION DE PILONNEMENT
Abstract: front page image
(EN)The present invention relates to a heave compensator for a riser, particularly a working riser (9), comprising a telescopic connection (10) with a first chamber (60) which is in fluid connection with the interior of the riser and a second chamber (62) which is connected with a source of pressure fluid. By varying the pressure in the second chamber in response to the movements of the platform, the telescopic connection can be arranged to move in correspondence with the platform's movements, thereby permitting access to the riser during working operations.
(FR)L'invention concerne un compensateur de pilonnement pour une colonne montante, en particulier pour une colonne montante d'intervention (9), qui comprend une liaison télescopique (10) présentant une première chambre (60) en communication fluidique avec l'intérieur de la colonne montante et une seconde chambre (62) qui est reliée à une source de fluide sous pression. Par variation de la pression dans la seconde chambre en réponse aux mouvements de la plate-forme, la liaison télescopique peut être amenée à se déplacer en correspondance avec les mouvements de la plate-forme, ce qui permet d'accéder à ladite colonne montante pendant les opérations d'intervention.
