Wireless monitoring device for underwater umbilical cable laying status

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...

Problems solved by technology

However, for the rotating drum, the pressure readings cannot be recorded in real time, and the normal laying of the umbilical cable needs to be interrupted frequently, which affects the overall laying efficiency. In addition, the monitoring of the performance of the cable is also difficult to achieve
