Abstract

L'invention concerne un bâti de base (1) pour une plate-forme offshore (7) à mise en place automatique, et un procédé de mise en place de la plate-forme offshore (7) à mise en place automatique. Selon l'invention, on ancre d'abord solidement le bâti de base (1) sur le fond marin (2). Ensuite, on déploie des colonnes porteuses (6) de la plate-forme offshore, par exemple hydrauliquement, jusqu'à ce qu'elles entrent en contact sous l'eau avec des régions de soutien (5) destinées à soutenir la plate-forme offshore (7). Les colonnes porteuses (6) sont ensuite solidement reliées au bâti de base (1). On peut ainsi mettre en place des plateformes offshore (7) à mise en place automatique en mer à de grandes profondeurs.
