Utvikling og testing av trådløst katodisk beskyttelsessystem (CP) for undersjøisk live-overvåking

Offentlig prosjektsammendrag

Offshore energy infrastructure such as FPSOs, subsea components, jackets, mooring lines, and offshore wind structures is constantly exposed to seawater corrosion. Cathodic Protection (CP) is the primary method to prevent corrosion-related failures. Today, CP monitoring is performed by divers, ROVs, or drop-cell surveys. These methods are costly, depend on IMR vessel availability and good weather, and only provide snapshots of the situation. This project will develop a new subsea wireless CP live monitoring system with a design life of 20+ years. The system will be designed by integrating CP sensors, batteries and subsea communication modem into retrofit clamp, and it will send data acoustically through the water to a receiver placed under platform/FPSO. The data will then be available on digital dashboards so operators can follow the condition of their subsea equipment in real time. The result will be lower costs, improved safety, longer asset life, and reduced environmental impact.
