What is the urgency of monitoring subsea cables?
Best insight from top research papers
The urgency of monitoring subsea cables lies in safeguarding critical undersea infrastructures (CUIs) like gas pipelines, power cables, and communication lines, which are vital for global connectivity and stability. Subsea cables face challenges like mechanical strain, yielding of copper conductors, and vortex-induced vibrations (VIV) due to rough seafloor conditions. Monitoring technologies such as Distributed Acoustic Sensing (DAS) and fiber-optic sensors enable the continuous surveillance of deep-sea currents, cable strain, and temperature, crucial for detecting anomalies and ensuring operational integrity. Additionally, leveraging fiber-optic sensing technologies on submarine telecommunication cables can provide real-time earthquake and tsunami monitoring capabilities, enhancing early warning systems and disaster response. Overall, monitoring subsea cables is imperative to prevent disruptions, ensure operational efficiency, and enhance global security and resilience.
