Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. And the features in the embodiments can be combined with each other.

[0021] The core of the present invention is to provide a wireless monitoring device for the laying state of the underwater umbilical cable, which can monitor the main parameters of the internal pipeline of the umbilical cable in real time without affecting the operation of the umbilical cable drum during the laying process of the umbilical cable, so as to judge whether the laying work is normal conduct.

[0022] Such as figure 1 As shown, in the wireless monitoring device for the laying state of the underwater umbilical cable provided by Embodiment 1 of the present invention, the underwater umbilical cable 1 is composed of several sections, and there are...

Abstract

The invention discloses a wireless monitoring device of a laying state of underwater umbilical cables. The wireless monitoring device comprises a pressure sensor (3), a wireless transmitter (4) and a wireless receiver (5); the pressure sensor (3) which is arranged on a pipeline joint (2) is used for detecting pressure of a pressure pipeline in the underwater umbilical cables (1); the pressure sensor (3) is connected with the wireless transmitter (4); and pressure signals which are detected through the pressure sensor (3) are sent to the wireless receiver (5) through the wireless transmitter (4). The wireless monitoring device of the laying state of the underwater umbilical cables has the advantages of enabling parameters of real-time-monitored pipeline pressure, cable conductor impedance and the like to be sent and received in a wireless mode in a laying process, solving the problem that the state of the underwater umbilical cables cannot be real-time-monitored during laying, enabling data to be real-time-monitored and being high in laying efficiency, low in input cost, small in workload, unrestricted in installation, safe and reliable and the like. The invention also provides a wireless monitoring method of the laying state of the underwater umbilical cables.

Description

technical field [0001] The invention belongs to the field of offshore oil engineering, and specifically refers to a device for monitoring the laying state of an underwater umbilical cable. Background technique [0002] With the acceleration of my country's offshore oil development from shallow sea to deep sea, the number of oil and gas fields using underwater production systems as the development model is increasing year by year. The underwater umbilical cable is the key equipment connecting the upper module and the underwater production facility, and serves as a channel for the electro-hydraulic control of the underwater production device. For long-distance umbilical cables, limited by the size of the installation drum, it usually needs to be manufactured in sections, and then wound on several installation drums respectively. During the laying process of the umbilical cable, each section is connected by an intermediate joint. [0003] For the traditional umbilical cable la...
