Problems solved by technology

The existing umbilical cables are armored with metal wires. Due to the limitation of the strength of the metal wire armored umbilical cables to the underwater static load ratio, the existing umbilical cables are usually not used in deep water (the maximum water depth is usually not more than 6000 meters). Unable to meet the requirements of deeper underwater production operations

Abstract

The invention provides an umbilical cable. The umbilical cable comprises a core, an inner protecting layer which is arranged at the outside of the core, and an armor layer which is arranged at the outside of the inner protecting layer, wherein the armor layer comprises a plurality of armor wires; and each armor wire comprises a base body which is manufactured through a fiber reinforced composite material. The umbilical cable has the characteristics of being low in specific gravity, and high in intensity; and the umbilical cable meets the requirement on deep underwater production work by beingcompared with an existing metal wire armor umbilical cable.

Description

technical field [0001] The invention relates to an umbilical cord, in particular to an umbilical cord which can be used for ultra-deep production operations. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] An umbilical is a type of cable used in subsea production operations. The existing umbilical cables are armored with metal wires. Due to the limitation of the strength of the metal wire armored umbilical cables to the underwater static load ratio, the existing umbilical cables are usually not used in deep water (the maximum water depth is usually not more than 6000 meters). It cannot meet the requirements of deeper underwater production operations. Contents of the invention [0004] In view of this, it is necessary to provide an umbilical cable with the characteris...
