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. 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.
