NRL researchers have developed an intrusion detection system for undersea pipelines that detect intruding objects as well as leakage effects from the pipelines.
Existing detection systems attempt to fully maintain the security and physical integrity of the pipelines. However, intrusions by undersea vehicles, underwater robots, divers, diver delivery vehicles, directed or intense sound waves, or leaking fluid warrants the need for a reliable, continual monitoring system that is able to detect objects or disturbances in proximity to the pipeline.
The innovative NRL intrusion detection system utilizes low-frequency (LF) structure-guided acoustic waves for detecting the intrusion since the waves propagate great distances without suffering geometrical signal attenuation. As a result, these waves can excite resonant characteristics in intruding objects that are a few wavelengths long or contain very compressible substances such as air.
- Enhanced sensitivity to pipeline intrusions
- Lower cost system requiring less maintenance than existing systems
- Intrusion Detection
- Leak Detection
