Monitoring system for the protection and Predictive maintenance of Submarine cable Infrastructures (PSI)
Monitoring system for the protection and Predictive maintenance of Submarine cable Infrastructures (PSI) project is aiming to develop a smart monitoring system that could prevent damages to a submarine cable by early warning of potentially harmful activities. These damages include earthquakes, submarine landslides or tsunamis. The technology applied will also study the location of and track marine mammals.
The submarine cable used in this project is MEDUSA.
PSI project reference PLEC2021-007875 funded by the Spanish Ministry of Science and Innovation MCIN/AEI/10.13039/501100011033 and by the European Union NextGenerationEU/PRTR program.
Technology used
The system pursued in this project comprises two essential elements in order to achieve its goal:
New developments based on these two elements will make possible the creation of a system that would be permanently scanning the natural and anthropogenic threats on the optical fibre infrastructure and would raise early warning alerts to trigger preventive actions.
Moreover, the availability of continuous DAS measurements of strain distribution along the optical fibre cable could also allow the development of extensive fatigue analysis of the infrastructure, therefore allowing a continuous lifetime assessment of the cable and enabling predictive maintenance of the stressed sections. This maintenance scheme would be completely innovative in the field of submarine cables infrastructure.
Consortium
The development of this system requires a unique blend of expertise that is actually present in the consortium: submarine cable experts, DAS developers, AI developers and seismology experts, from both the industry and the academy, will work together in protecting the backbone of our international communication network.
Objectives of the project
This project aims at designing an intelligent and comprehensive monitoring and data processing system for predictive maintenance and protection of infrastructures at the marine environment and the land-sea interface, to be used by different socioeconomic sectors. The main goal of the project is to provide tools for an integrated and resilient management of critical marine infrastructures.
Objective 1:
Development of efficient DAS technology for underwater measurements.
Objective 2:
Fatigue and lifetime analysis of underwater cables using long-term strain series. Development of guidelines for optimization of cable deployment. Monitoring optimization via use of high-resolution distributed sensing.
Objective 3:
Development of efficient artificial intelligence for the early warning of anthropogenic threats relevant for the cable integrity.
Objective 4:
Characterization of natural events through the acquisition and near real-time processing of submarine DAS data.
