Abstract

Installation sous-marine à utiliser dans le forage offshore et l'exploitation, respectivement, de puits de pétrole en eau profonde et moyennement profonde. Ladite installation comporte une station intermédiaire se présentant sous la forme de jambes de force d'un corps creux flottant (16), ancrées dans le fond marin (10) et situées à une profondeur sensiblement plus proche de la surface de la mer que du fond (10). Au moins un pipeline de transport d'hydrocarbures s'étend entre le corps flottant (16) et le fond marin pour le transfert d'hydrocarbures depuis le réservoir jusqu'audit corps flottant (16). Au moins un train de chemises du tubage (18a-18h) constitue l'ancrage formant jambe de force du corps flottant (16). L'invention concerne aussi un procédé de construction d'une installation sous-marine.
