Pipeline Monitoring

In industries where liquids are transported in pipelines over long distances, the integrity and health condition of pipelines are extremely critical. Due to their economic importance, these pipelines are potential targets of malicious intrusion and attacks. On top of this, mechanical cracks and fatigue can lead to disastrous spills and severe economic and environmental consequences.

Protect and ensure pipeline integrity with Koheras lasers

Today, optical sensing systems are being deployed for pipeline security and integrity monitoring as preventive means to continuously protect or monitor pipelines.

The systems are based on interferometric sensing where ultra-stable, low-noise lasers – such as our Koheras lasers – interrogate an optical fiber acting as one long continuous sensor along the pipeline.

Acoustically sensitive fibers send information on event type and position to the laser.

The systems are intelligently designed to distinguish acoustic noise of interest from background noise. Alarms will only be triggered by relevant events such as intrusion, leakage, or theft.

Early detection of leakage is a huge benefit for the environment as well as the pipeline owner.

Long range and high reliability

World-leading acoustic sensing systems use our Koheras lasers due to the unprecedented low noise and long coherence length that enable measurement ranges up to 50-100 km and high sensitivity to acoustic events.

Our fiber laser design is inherently compact and robust. It is developed for a long lifetime in demanding environments where uptime is critical. With documented low failure rates, we proudly deliver the most reliable low noise lasers on the market.
