PrismaSubsea keeps your underwater cables and pipelines up and running, monitoring submarine infrastructure.

How it works

Subsea Response-ability at Scale

PrismaSubsea enables subsea pipeline and cable operators to monitor their submarine infrastructure accurately for hundreds of kilometers in real-time without installing any additional sensors. Leak detection, tampering discovery, and faults without the nuisance of false alarms.

Submarine pipelines, power and telecommunications cables are the backbone of the energy ecosystem and the digital world. Operators need to deal with damages to their assets from planned or unplanned activity, vandalism, and of course, the fear of leaks. Keeping your subsea assets running smoothly is hard. We know it, and we’re here to help.

PrismaSubsea monitors subsea infrastructure without the need to install extra sensors on the pipe or cable. Instead, it’s easy deployment, utilizing the existing optical fiber laid along the pipeline or the cable. PrismaSubsea Identifies events such as leaks, tampering, human and pig activity.

With a short ramp-up time and effort, PrismaSubsea is effective on the installation day. Reflecting a significant cost reduction in subsea monitoring, it is a solution that is always there, 24×7, anywhere, anytime, and in any weather.

It is your response-ability at a subsea scale.

Solution Architecture

Subsea infrastructure operators have deployed fiber optic cables along their pipelines, powerlines for many years. PrismaSubsea turns the existing optical fiber into a set of highly sensitive distributed sensors extending for hundreds of kilometers. The solution connects to one single dark fiber at a substation, sensing the entire asset. PrismaSubsea’s machine learning algorithms take the detailed data collected on the pipeline, powerline, or telecom cable to detect and classify events, pinpointing them to exact locations in real-time. As a result, alerts have unprecedented accuracy – removing the nuisance of false alarms.​

All the information and alerts are concentrated into one command and control center. This way, PrismaSubsea can continue scaling with the subsea system. Moreover, with the revolutionary Pay-as-You-Grow service model – PrismaSubsea is your way to take off some of the burdens of responsibility.
