    摘要: A method of making an armored cable having a polymer covering where the bond between the armor and the covering is controlled by introducing particulate matter at the interface of the armor and covering. A filler material is applied to the exterior surfaces of the cable strength elements in order to inhibit the formation of voids in the polymer covering that would otherwise promote water migration along the cable.

    摘要: An umbilical (600) for the transfer of fluids and/or electric current/signals, particularly between the sea surface and equipment deployed on the sea bed (e.g., in deep waters), is provided. The umbilical contains a plurality of elongated umbilical elements (e.g., two or more), such as a channel element (603), fluid pipe (604), electric conductor/wire (606) (e.g., optic fiber cable), armoring wire, etc., enclosed within an outer sheath (e.g., plastic sheath). The umbilical also contains at least one reinforcing rod (607) formed from a plurality of unidirectionally aligned fiber rovings embedded within a thermoplastic polymer matrix. The present inventors have discovered that the degree to which the ravings are impregnated with the thermoplastic polymer matrix can be significantly improved through selective control over the impregnation process, and also through control over the degree of compression imparted to the ravings during formation and shaping of the rod, as well as the calibration of the final rod geometry. Such a well impregnated rod has a very small void fraction, which leads to excellent strength properties for reinforcing the umbilical elements.
