Title (EN) METHOD AND APPARATUS OF HOT TAPPING MULTIPLE COAXIAL OR NESTED STRINGS OF UNDERWATER PIPING AND/OR TUBING FOR OVERTURNED WELLS OR PLATFORMS
(FR) PROCÉDÉ ET APPAREIL DE TARAUDAGE À CHAUD DE MULTIPLES TRONÇONS COAXIAUX OU EMBOÎTÉS DE TUYAU ET/OU TUBE SOUS-MARINS POUR PUITS OU PLATEFORMES RENVERSÉS
Abstract: front page image
(EN)A method and apparatus for tapping into a pressurized multiple strings of coaxially situated tubulars for wells and/or platforms which have overturned wherein the tapping occurs underwater via a diver or remotely operated vehicle. The assembly includes a tapping tool connectable to the tubular via a saddle connection and an adjustable tapping clamp with adjustable support/locking feet, compression plate with view ports, and angularly adjustable hot tapping system, along with a drill/saw system.
(FR)La présente invention se rapporte à un procédé et à un appareil de taraudage de multiples tronçons sous pression de tubes coaxiaux pour puits et/ou plateformes qui se sont renversés, le taraudage ayant lieu sous la mer par l'intermédiaire d'un plongeur ou d'un véhicule télécommandé. L'ensemble comprend un outil de taraudage pouvant être relié au tube par le biais d'une sellette de raccordement et d'un collier de taraudage réglable pourvu de pieds de support/verrouillage réglables, d'une plaque de compression pourvu de hublots, et d'un système de taraudage à chaud angulairement réglable, associé à un système de forage/sciage.
