Title (EN) APPARATUS AND METHODS FOR SUPPORTING A SUBSEA WELL
(FR) APPAREIL ET PROCÉDÉS DE SUPPORT D'UN PUITS SOUTERRAIN
Abstract:
(EN) A well support structure includes a well support base for urging below a bottom of a body of water. A first support is coupled to the well support base at a first longitudinal support level. A first load transfer device is operatively coupled between the first support and a wellbore tubular component. At least a second support is coupled to the well support base at a second longitudinal level below the first longitudinal support level. The wellbore tubular component extends between a longitudinal position above the first support to at least the longitudinal position of the at least a second support. Means for transferring load is provided between the wellbore tubular component and the at least a second support.
(FR) Cette invention concerne une structure de support de puits, comprenant une base de support de puits destinée à être poussée en dessous d'un fond d'un corps d'eau. Un premier support est accouplé à la base de support de puits à un premier niveau de support longitudinal. Un premier dispositif de transfert de charge est fonctionnellement accouplé entre le premier support et un composant tubulaire de puits de forage. Au moins un second support est accouplé à la base de support de puits à un second niveau longitudinal en dessous du premier niveau de support longitudinal. Le composant tubulaire de puits de forage s'étend entre une position longitudinale au-dessus du premier support et au moins la position longitudinale du ou des second(s) support(s). Des moyens de transfert de charge sont disposés entre le composant tubulaire de puits de forage et le ou les second(s) support(s).
