1. Background introduction

As an indispensable part of modern Marine scientific research and engineering construction, Marine towing cable plays an important role. They are widely used in the fields of seabed geological survey, Marine resource exploration and Marine environment monitoring. However, due to prolonged exposure to the harsh Marine environment, the towing cable is susceptible to corrosion, friction, damage and breakage, which has caused problems for scientific research and engineering projects. In order to ensure the stable operation of the towing cable and maximize the value of use, we have developed an innovative Marine towing cable monitoring and optimization scheme.

Ii. Project overview

The purpose of this project is to use hydrophones, seabed seismographs, sonar, acoustic releasers, transducers and other equipment to conduct real-time monitoring of Marine towing cables and provide corresponding optimization recommendations to improve the safety, stability and lifetime of towing cables.

3. Technical solutions

Hydrophone: By installing hydrophones on the surface of the towing cable, the cable acoustic signal is monitored in real time. When there is an abnormal sound, such as friction, vibration or other abnormal noise, the system will automatically alarm and record relevant data to help analyze the root cause of the problem.

Seabed seismometers: Real-time monitoring of crustal movements by installing seismometers on the seafloor near the towing cable. In the event of an earthquake or other geological disaster, the system will automatically trigger an alarm and provide seismic data and analysis of the possible impact on the cable.

Sonar: Acoustic signals are sent to the towing line by sonar equipment to detect the integrity of the line. When the sound wave encounters the damage point in the cable, its propagation characteristics will change abnormally, and the system will immediately issue an alarm so that repair measures can be taken in time.

Acoustic releaser: The acoustic releaser releases a specific frequency of sound to detect water flow, obstacles, and other information around the tow line. The data is analyzed and preventive maintenance recommendations are made to help reduce problems such as corrosion and friction.

Transducers: Transducers convert sound signals into electrical signals, which are then transmitted to a central processing unit. The central processing unit has high performance data processing capability, which can analyze and process the received signals in real time, and determine whether there are abnormal conditions in the cable according to the preset algorithm.

4. Project effect

Improve the safety and stability of the towing cable: Through real-time monitoring and early warning, the system can detect potential problems such as friction, wear, break, etc., and provide corresponding optimization recommendations to ensure the safe operation of the towing cable and extend the service life.

Reduce accident risk and repair costs: With early warning and optimized recommendations, damage and breakage of towing lines can be reduced, thereby reducing accident risk and repair costs.

Improve the success rate of research and engineering projects: Monitoring and optimizing the stability and reliability of towing cables can help improve the success rate of research and engineering projects and ensure the accurate acquisition of the required data.

Data visualization and remote monitoring: The system will process and analyze the collected data, and provide a visual display in the form of charts to facilitate data analysis and decision-making by managers. At the same time, it supports remote monitoring, so that the operator can remotely monitor the status and operation of the towing cable at any time.

V. Summary

Through the implementation of this project, we have provided a set of innovative monitoring and optimization solutions for Marine research and engineering projects, effectively improving the safety, stability and service life of the tow cable. We will continue to make technological innovations and product optimizations to provide our customers with more reliable and efficient Marine towing cable monitoring solutions, and to promote the development of Marine science and engineering.
