Lumetec turns subsea fiber optic cables into a real-time awareness network. Using multi-modal sensing over long distances, the system captures and identifies all activity within its range, from ocean currents and earthquakes to approaching vessels — and even changes to the cables. Hendro Dahlan Situmorang, Jakarta – Indonesia is strengthening its national tsunami early warning system by utilizing undersea fiber optic cable technology to detect seismic activity, particularly along the country's vulnerable megathrust zones. The initiative is a collaboration between Gadjah Mada. In a new study published in The Seismic Record, researchers show how unused telecommunications fiber optic cable can be transformed for offshore EEW. Jiuxun Yin, a Caltech researcher now at SLB, and colleagues used 50 kilometers of a submarine telecom cable running between the United States and. Lumetec accurately detects malicious activity near your offshore rigs and platforms and spots potential threats to your subsea pipelines. Spot anchor drags and negligent fishing events before they cause any damage. Discover the effects of underwater earthquakes and strong currents. Lumetec turns. The EIC-funded SAFE project proposes a straightforward, low-cost, easy and reliable solution that takes advantage of the broadly available infrastructure of submarine fibre-optic cables widely used for communication. The team detailed their acoustic sensing technology in the Journal of Geophysical Research: Solid Earth.
