Monitoring & Maintenance

Stay Ahead: Leverage on Prysmian Comprehensive Solutions to navigate the unforeseenable

In an increasingly interconnected and decentralised energy environment, submarine cables play a key role to enable power transmission via interconnectors or from offshore wind farms. Laid down in extreme water depths conditions hundreds of metres under sea level, subsea cables are threatened by high risk of damages. Preventing cable harm and being able to resolve it with minimal downtime is crucial to transmission system operators and offshore facilities operators, which might suffer severe losses from interruptions of energy availability. We offer a combination of cutting-edge monitoring capabilities with a preventive and reactive maintenance services suite in a unique and effective solution to provide a complete effective management of submarine cable damages, from detection to recovery, that remarkably reduces total cost of ownership.
