(EN) HULL-TO-CAISSON INTERFACE CONNECTION ASSEMBLY FOR SPAR PLATFORM
(FR) CONNEXION D'INTERFACE ENTRE COQUE ET CAISSON POUR PLATEFORME SPAR
Abrégé
(EN)
A hull-to-caisson interface connection assembly accommodates high-tension loads between the hull (12) and a caisson (20) of a Spar-type platform (10), while facilitating angular flexing motion and constraining lateral and axial movement. The interface connection assembly includes an annular bearing shoulder (32) at the top end of caisson (20), and a laminated bearing assembly (22) mounted in the bottom of the hull (12) and defining a passage (23) through which the upper portion of the caisson (20) passes, so that the caisson shoulder (32) seats against the upper end of the bearing assembly (22). The bearing assembly (22) includes a laminated structure of alternating steel (38) and elastomeric (40) flex elements, bonded to each other to flex together as a unit, rather than sliding relative to each other. The laminated structure of the bearing assembly (22) supports the vertical tensile loads applied by the weight of the caisson (20) on the hull (12), while also accommodating the angular loads applied between the caisson (20) and the hull (12).
(FR)
Ensemble connexion d'interface entre coque et caisson s'adaptant au fortes charges de tension entre la coque et un caisson d'une plateforme de type SPAR, tout en facilitant un mouvement de flexion angulaire et en contraignant les mouvements latéraux et axiaux. L'ensemble de connexion d'interface comprend un épaulement de palier annulaire à l'extrémité supérieure du caisson et un ensemble palier stratifié monté dans le fond de la coque et définissant un passage au travers duquel passe la partie supérieure du caisson, afin que l'épaulement du caisson repose contre l'extrémité supérieure de l'ensemble palier. L'ensemble palier comprend une structure stratifiée alternant des éléments d'acier et des éléments flexibles d'élastomère, liés les uns aux autres pour fléchir à l'unisson, plutôt qu'en glissant les uns par rapport aux autres. La structure stratifiée de l'ensemble palier supporte les charges de tension verticales appliquées par le poids du caisson sur la coque, tout en acceptant les charges angulaires appliquées entre le caisson et la coque.
