Acoustic Leak Detection in Marine Pipelines (Buried & Submerged Lines) — ATEX
Detects leaks in buried or submerged pipelines
Acoustic
Quick Overview
| Problem | Marine pipelines—buried underground or submerged underwater—are difficult to inspect and monitor continuously. Small leaks often remain undetected until environmental damage, product loss, or regulatory violations occur, especially in ATEX-classified fuel and chemical zones. |
| Solution | SENSAiO’s ATEX-certified acoustic sensors continuously monitor pipelines for abnormal acoustic signatures associated with leaks, impacts, or structural degradation, enabling early detection without excavation or shutdown. |
| Value | Early leak detection • Reduced environmental impact • Lower inspection cost • Improved regulatory compliance |
| ATEX | Zones 0–2 • Ex ia IIC T4 Gb certified acoustic sensors |
The Operational Challenge
Marine and port pipeline networks include:
- Fuel transfer pipelines between terminals and berths
- Buried pipelines under quays and storage areas
- Submerged pipelines in ports, rivers, and coastal zones
- Product lines for hydrocarbons and chemicals
These assets are exposed to:
- External corrosion and erosion
- Ground movement and settlement
- Anchor drag or dropped objects
- Progressive seal or weld degradation
Traditional leak detection methods rely on:
- Periodic pressure testing
- Mass balance analysis
- Visual inspection or ROV surveys
These methods are intermittent, expensive, and often detect leaks after significant product loss.
Why Acoustic Leak Detection Matters
Fluid leaks generate distinct acoustic emissions as product escapes through defects.
Continuous acoustic monitoring enables operators to:
- Detect micro-leaks before pressure loss becomes visible
- Identify sudden rupture or impact events
- Monitor pipeline integrity continuously
- Reduce reliance on excavation or ROV inspection
Acoustic detection is particularly effective where visual access is limited or impossible.

FAQ - Common Questions
Are Sensa.io sensors compatible with any gateway or network?
What ATEX certifications apply to Sensa.io devices?
All hazardous-area models are certified Ex II 2 G Ex ia IIC T4 Gb and IECEx approved for Zones 0–2.
What is the typical battery life?
Up to 10 years at 15-minute intervals, depending on signal strength and environment.
How are the sensors integrated into existing systems?
Through standard protocols — LoRaWAN, Modbus, MQTT, REST API — no proprietary middleware needed.
How does predictive maintenance reduce OPEX?
Early anomaly detection reduces emergency interventions by 30–40 %, extends equipment life and lowers energy costs.
What does the Sensa.io Valve Position Sensor actually measure?
The device detects real-time valve position states—open, closed, or intermediate—with high accuracy. It continuously sends this information wirelessly to your monitoring dashboard.
Can this sensor detect partial valve movement or stuck valves?
Yes. The sensor identifies irregular patterns such as partial movement, delayed response, or stuck valves, enabling early maintenance before failure occurs.
Is this sensor suitable for manual, motorized, and actuated valves?
Yes. It supports a wide range of valve types including ball, gate, butterfly, actuator-driven, and manual valves.
How fast does it update the valve position?
You can configure the reporting interval—from seconds to minutes—depending on your operational and battery needs.
How long does installation take?
Most installations take under 10 minutes. The sensor mounts using brackets or clamps without modifying existing valves.
