Title (EN) EQUIPMENT FOR INSTALLATION OF MODULES ON FIXED UNDERWATER BASES, SPECIALLY FOR UNDERSEA PETROLEUM WELLS
(FR) EQUIPEMENTS POUR INSTALLATION DE MODULES SUR DES BASES SOUS-MARINES FIXES, NOTAMMENT POUR DES PUITS DE PETROLE SOUS-MARINS
Abstract: front page image
(EN)An equipment for installation of modules (5) on underwater bases (1) that have guide posts (3) for the alignment of a set to be connected, composed of a connecting rod (4), a module (5) and a retrievable tool (6) and which has guide funnels (7) that fit to said guide posts (3) of the bases (1). The purposes of the invention are to provide an equipment of this type that reduces requirements with regard to the precision of mutual positioning between funnels (7) and set (4, 5, 6) during assembly and that reduces the costs of its manufacture. This is attained by the fact that the guide funnels (7) will be built into a rigid structure (8, 10) rotatory in relation to the set (4, 5, 6) and by the fact of this structure being modulated on the tool (6).
(FR)Equipements pour installation de modules (5) sur des bases sous-marines (1) qui possèdent des piliers-guides (3) permettant l'alignement d'un ensemble à assembler, composés d'une barre de connexion (4), d'un module (5) et d'un outil amovible (6), et qui présente des entonnoirs-guides (7) s'emboîtant sur lesdits piliers-guides (3) des bases (1). L'invention a pour objet de fournir un équipement de ce type permettant de réduire les exigences quant à la précision du positionnement mutuel entre les entonnoirs (7) et l'ensemble (4, 5, 6) lors du montage, et réduisant les coûts de fabrication. On y parvient grâce au fait que les entonnoirs-guides (7) sont solidaires d'une structure rigide (8, 10) rotative par rapport à l'ensemble (4, 5, 6) et que cette structure est montée sur l'outil (6).
