Special Issue Information

Dear Colleagues,

The current research status of underwater methane pipeline leak detection is a complex issue involving multiple fields. Current research primarily focuses on developing and improving various technologies and methods to timely and accurately detect leaks in underwater methane pipelines, in order to minimize the environmental and human health impacts of leaks. Some commonly used technologies include acoustic detection, remote sensing techniques, chemical sensors, and machine learning algorithms.

Acoustic detection is a commonly used method that involves monitoring changes in sound waves around the pipeline using underwater acoustic sensors to identify possible leaks. Remote sensing techniques utilize equipment such as satellites, underwater drones, or underwater robots to detect pipeline leaks by monitoring underwater surface temperature, gas concentration, or underwater optical features. Chemical sensors can directly measure gas concentrations in the underwater environment to identify possible leak points. Additionally, machine learning algorithms are widely used to process and analyze large amounts of sensor data to improve the accuracy and efficiency of leak detection.

Despite some progress being made, underwater methane pipeline leak detection still faces challenges such as the complex underwater environment, interference from underwater noise, and the identification of leak signals. Therefore, future research needs to further enhance the sensitivity and accuracy of detection technologies to address the increasing demands of underwater methane development activities and environmental protection.

This Special Issue aims to and methods of underwater methane pipeline leakage detection, sensing and positioning, including but not limited to the following topics:

  • Underwater methane pipeline leak remote sensing and locating technology;
  • MEMS sensors of underwater methane pipeline leak detection and remote sensing;
  • Algorithms of remote sensing, detecting and locating underwater methane pipeline leaks;
  • AI-enabled methods of the underwater methane leak sensing remotely;
  • New sensors, i.e., MEMS sensors, sensors arrays, to detect the underwater methane pipeline leak;
  • Multi-sensor integration of the underwater methane pipeline leak detection and position;
  • Real-time monitoring and mapping of the underwater methane pipeline leak.
  • Other remote sensing technologies or sensors for underwater methane pipeline leak remote sensing.

The increasing discovery of underwater methane leakage underscores the importance of monitoring methane emissions for environmental protection. Underwater remote sensing of methane leakage is critical and meaningful to protect the environment. The construction of sensor arrays is recognized as the most effective technique to increase the accuracy and sensitivity of underwater remote sensing of methane leakage. With the aim of improving the reliability of underwater methane remote-sensing sensor arrays, in this work, a deep learning method, specifically an explainable sparse spatio-temporal transformer, is proposed for detecting the failures of the underwater methane remote-sensing sensor arrays. The data input into the explainable sparse block could decrease the time complexity and the computational complexity (O (n)). Spatio-temporal features are extracted on various time scales by a spatio-temporal block automatically. In order to implement the data-driven early warning system, the data-driven warning return mechanism contains a warning threshold that is associated with physically disturbing information. Results show that the explainable sparse spatio-temporal transformer improves the performance of the underwater methane remote-sensing sensor array. A balanced F score (F1 score) of the model is put forward, and the anomaly accuracy is 0.92, which is superior to other reconstructed models such as convolutional_autoencoder (CAE) (0.81) and long-short term memory_autoencoder (LSTM-AE) (0.66).
