Problem
Subsea power cables are susceptible to various degradation mechanisms like abrasion, fatigue, and torsion, which can lead to costly failures and operational downtime. Current monitoring methods often lack the precision and continuous data required for effective preventative maintenance, leaving asset owners in the dark about their cable's true health.
Solution
Indeximate provides a continuous subsea cable health monitoring service utilizing fiber optic sensing technology. This non-invasive solution connects to a cable's existing fiber, transforming it into a network of highly sensitive virtual strain gauges that are polled thousands of times per second. By analyzing vibration responses to power flow, the platform detects and quantifies degradation mechanisms such as abrasion, fatigue, and torsion, providing precise geolocation and urgency for identified issues. This enables proactive, preventative maintenance, reducing the risk of catastrophic failures and optimizing operational efficiency.
Target Audience
Indeximate serves offshore wind farm operators, subsea cable asset owners, and offshore energy infrastructure developers who require robust monitoring and maintenance solutions for their subsea power cables.
