drilling platform underwater safety monitoring system‌ is a passive sonar monitoring solution based on a vertical hydrophone array, specifically designed for offshore oil and gas production facilities. It aims to ensure comprehensive safety of the platform and surrounding waters through round-the-clock underwater acoustic surveillance. Centered on meeting operators’ core requirements for ‌anti-intrusion, leakproof, and anti-collision‌, the system integrates real-time sensing, intelligent identification, and precise positioning capabilities to establish an active underwater security barrier.

‌drilling platform underwater safety monitoring system‌ is a passive sonar solution based on a vertical hydrophone array, designed for offshore oil and gas facilities. It enables 24/7 acoustic surveillance to proactively address underwater security challenges, transforming platform defense from passive to active.

Application Areas‌

• ‌Early detection of underwater leaks‌: Continuous acoustic monitoring of subsea pipelines, wellheads, and other infrastructure to capture characteristic noise from hydrocarbon leaks, enabling early warning and minimizing environmental and safety risks.

• ‌Structural health monitoring‌: Listening for stress waves generated by fatigue or impact on platform piles, mooring chains, and other metal structures, providing critical data for structural integrity assessment.

System Workflow‌

1. ‌Acoustic sensing‌: Vertically deployed hydrophone arrays continuously collect underwater sound signals, effectively suppressing surface noise interference.

2. ‌Intelligent processing‌: Embedded recorders perform real-time filtering and feature extraction, using acoustic signature libraries to automatically identify targets and significantly reduce false alarms.

3. ‌Data transmission & localization‌: Key data is wirelessly transmitted to the platform’s central control room; multi-array coordination enables 3D target positioning and trajectory tracking.

4. ‌Alarm & response‌: Upon alert, the system can trigger联动 (interlock) with underwater lighting, acoustic deterrents, or ROVs for verification and threat mitigation, forming a closed-loop response.

With core capabilities in ‌high sensitivity, intelligent recognition, and round-the-clock operation‌, the system empowers drilling platforms to achieve proactive underwater situational awareness.
