Guardians of the Deep: Designing a Proactive Security System for Subsea Cable Protection

Leveraging Distributed Acoustic Sensing (DAS) and Real-Time Data Integration to Safeguard Global Communication Networks

[Project Overview]

A prototype system for real-time subsea cable intrusion detection using DAS, AIS, and satellite data, designed to help operators protect global communication infrastructure.

[Problem Statement]

Subsea cables are critical but vulnerable to damage. Without real-time monitoring, threats go undetected, causing costly disruptions. This project delivers a unified solution for early threat detection and proactive protection.

[Persona]

Alex Carter

Network Operations Manager

I want to be able to be more proactive and prevent accidents.

Age: 38

Location: Los Angeles

Tech Proficiency: High

Gender: Male

[Goal]

Quickly identify and respond to potential threats to subsea cables before damage occurs.

Receive clear, real-time alerts with actionable information to prioritize responses.

Use stored data to analyze trends, improve future threat detection, and support liability assessments.

[Frustrations]

Uses multiple disconnected systems, making it hard to correlate data and identify threats.

Receives delayed or unclear alerts, leading to slower responses and higher repair costs.

Struggles to differentiate between false alarms and real threats.

[Process]

[01] User Research

Conducted interviews with 6 submarine cable specialists to better understand their struggles and challenges.

Interviewed 3 DAS specialist to better understand the limits of the technology and how far we can go with it.

Benchmarked against competitors to identify best practices for notification management.

[02] Insights

Users will often work with a set of multiple monitors.

DAS system is not super precise on it's own. It requires data triangulation to better precide the type of alert and incident position.

Vessel and cable insurance companies would find thos tool interesting for better applying liability to actors and create reports.

[03 Design Solution]

Added correlation and it's probability to all vessels and alerts. With AI helping user understand the context and percentage.

Incorporated DAS, GPS and AIS systems so the information can be triangu;ated generating more precise measurements.

Incorporated a functinality to call costal guards and dispatch drones, so managers can be more proactive and avoid accidents.

[Outcome]

Project green-lighted by company executives.
100% Aprooval in internal testing.
Project continuation and strenghted partnership.

[Key Learnings]

Embracing complexity without overwhelming the user.

Tesler’s law guided us to find the right balance between functionality and usability in subsea cable monitoring.
