Abstract

La présente invention concerne une plateforme de forage auto-élévatrice spécialement adaptée à la glace comportant une plateforme monopode sur pile conique, servant à la fois au forage de puits et à la production d'hydrocarbures en des emplacements susceptibles d'être pris par la glace. La plateforme de forage selon l'invention fonctionne comme une plateforme de forage auto-élévatrice classique lorsqu'elle se trouve en pleine eau avec la coque auto-élevée hors de l'eau. Cependant, dans des conditions où de la glace est présente, les jambes sont maintenues en place à l'aide d'emboîtures incorporées au fond océanique afin de résister au mouvement latéral de la plateforme de forage, et dans des douilles fixées à la plateforme monopode sur pile conique. La coque et la plateforme monopode sur pile conique sont constituées de surfaces d'écartement de la glace servant à écarter et à briser la glace entrant en contact avec la coque et la plateforme monopode.
