Abstract

L'invention concerne des plates-formes de forage et/ou des plates-formes pétrolières destinées à la recherche, à l'extraction, au traitement et/ou au transport subséquent du pétrole ou de gaz naturel. Lesdites plate-formes se caractérisent, en particulier par une possibilité de placement fixe et une possibilité d'enlèvement simples. À cet effet, la plate-forme de forage et/ou la plate-forme pétrolière comprend une embase gravitaire flottante, une tour tubulaire et une plate-forme flottante ou un navire de forage. L'embase gravitaire flottante comprend une plaque solide de béton, de béton armé, d'un composite avec du béton ou d'une combinaison de ceux-ci. En outre, au moins une chambre remplissable est située, laquelle est vide pour flotter et laquelle est remplie pour rechercher, extraire, traiter et/ou transporter subséquemment le pétrole ou le gaz naturel. La tour tubulaire est ouverte des deux côtés et raccordée à l'embase gravitaire de telle sorte que la tour tubulaire coupe l'embase gravitaire et en fait saillie au moins vers la surface de l'eau. En outre, la plate-forme flottante ou le navire de forage est raccordé, pour transporter respectivement des équipements de recherche, d'extraction, de traitement et/ou de transport subséquent du pétrole ou du gaz naturel, à la tour tubulaire.
