Monitoring & Mantainance Services

In an increasingly interconnected and decentralised energy environment, submarine cables play a critical 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, as proven by the 90 cable damages occurred in the last 7 years totaling over €350 mn claim to insurances. Preventing this kind of events and being able to resolve them minimising downtime is crucial to TSO and offshore facilities operators, which might suffer severe losses from interruptions of energy availability. Prysmian Group combined full high-tech monitoring capabilities with preventive and reactive maintenance services in a unique and effective solution, Power Link Cable Solutions, to provide a complete effective management of subsea cable damages, from detection to recovery, that dramatically lowers downtime and remarkably reduces total cost of ownership.
