Abstract

Structure de support pour plates-formes maritimes. Selon l'invention, cette structure est caractérisée en ce qu'elle comporte une colonne reposant sur le fond de la mer, cette colonne étant formée d'au moins deux parties qui peuvent basculer l'une par rapport à l'autre, à partir d'une position initiale, dans un plan ou dans des plans qui sont transversaux à l'axe de la colonne, du fait que les différentes parties sont disposées l'une par rapport à l'autre grâce à des moyens définissant des axes de basculement circonférentiels, axes autour desquels lesdites parties peuvent basculer l'une par rapport à l'autre et en ce que ladite structure comporte des moyens amortisseurs agencés pour contrôler le retour desdites parties à leur position initiale à partir d'une position de basculement relatif. Application aux plates-formes de forage et de services en mer.Support structure for maritime platforms. According to the invention, this structure is characterized in that it comprises a column resting on the seabed, this column being formed of at least two parts which can tilt relative to one another, from from an initial position, in a plane or in planes which are transverse to the axis of the column, owing to the fact that the different parts are arranged with respect to each other by means of means defining tilting axes circumferential, axes around which said parts can tilt relative to one another and in that said structure comprises damping means arranged to control the return of said parts to their initial position from a position of relative tilting. Application to drilling platforms and offshore services.
