Title (EN) SYNTHETIC CABLE PROVIDED WITH PROTECTION AGAINST SOIL INGRESS
(FR) CABLE SYNTHETIQUE AVEC PROTECTION CONTRE LA PENETRATION DE TERRE
Abstract:
(EN) A new form of construction for synthetic cables used for the anchoring of floating platforms in offshore oil production is described. A desirable requisite for this application is that the durability of the cable is not affected by deterioration of its strong core by virtue of the aggressive mechanical action of particles of the sea bed which might penetrate the cable and reach its core. For this purpose a layer (3) to protect the core (1) comprising a strip of polymer material placed in helical fashion which permits the passage of water and prevents the passage of particles of the sea bed towards the core (1) is placed between the cable core (1) and its outer braided protective layer (2).
(FR) L'invention concerne une nouvelle conception des câbles synthétiques permettant d'ancrer les plates-formes flottantes destinées à la production pétrolière en mer. Une exigence désirable pour cette application est que la durabilité du câble ne soit pas affectée par la détérioration de son âme dure, due à l'action mécanique agressive des particules contenues dans le fond de la mer, qui risquent de pénétrer dans le câble et d'atteindre son âme. Pour cela, on place, entre ladite âme (1) et sa couche protectrice tressée externe (2), une couche (3) destinée à protéger l'âme (1), constituée d'une bande de matériau polymère en spirale, qui permet le passage de l'eau tout en empêchant les particules du fond de la mer d'atteindre l'âme (1).
