Abstract

Una envoltura (2) para un caño conductor, tubo ascendente o piloto (1) de una plataforma marítima consiste en una lámina compuesta que comprende una capa exterior (3) de material flexible, resiliente e impermeable, y una capa interior (4) de fieltro impregnado con gel tixotrópico. Los bordes de la envoltura que han de ser juntados están provistos de anillos (5), convenientemente formados por la capa exterior que se encuentra plegada hacia atrás y provista de aberturas, cuyos anillos se interdigitan para recibir una barra de sujeción plana (12). La envoltura se estira para que los anillos se superpongan empleando soportes temporales (7 , 19) asegurados al lado del exterior de la envoltura. Según una modalidad, los soportes son vigas unidas a paneles flexibles (8) con fibras que se entrelazan con paneles fibrosos (6) en el exterior de la envoltura. Según otra modalidad, la capa exterior está plegada cerca de cada borde anillado con un panel (16) que tiene aberturas (17) para elementos de anclaje (21) que han de ser introducidos para capturar el panel. Estos elementos permanecen expuestos en las ventanas para acoplarse con las respectivas vigas (19), preferentemente por medio de una varilla paralela que permite la articulación. La figura 1 es una sección transversal de parte de un caño conductor que muestra el cierre de una envoltura protectora. La figura 2 es una vista frontal de otra envoltura que muestra la unión antes del final.An envelope (2) for a conductive, riser or pilot pipe (1) of an offshore platform consists of a composite sheet comprising an outer layer (3) of flexible, resilient and waterproof material, and an inner layer (4) of felt impregnated with thixotropic gel. The edges of the envelope to be joined are provided with rings (5), conveniently formed by the outer layer which is folded back and provided with openings, the rings of which interdigitate to receive a flat holding bar (12). The wrap is stretched so that the rings overlap using temporary supports (7, 19) secured to the side of the outside of the wrap. According to one embodiment, the supports are beams attached to flexible panels (8) with fibers that interlock with fibrous panels (6) on the outside of the casing. According to another embodiment, the outer layer is folded near each ringed edge with a panel (16) having openings (17) for anchoring elements (21) to be inserted to capture the panel. These elements remain exposed in the windows to engage with the respective beams (19), preferably by means of a parallel rod that allows articulation. Figure 1 is a cross section of part of a conductive pipe showing closure of a protective envelope. Figure 2 is a front view of another wrapper showing joining before end.
