Combined power quality and condition monitoring of offshore network cabling systems and installations

A radical rethink of existing asset management practices and implementation of novel solutions for power quality (condition and performance) monitoring, system state identification and fault detection are required to reduce the cost and increase security, reliability, and quality of electricity supplied from offshore generation systems. Recent estimations suggest that cost of offshore wind generated electricity (from development, construction and operations) should fall to about £100/MWh by 2020 to make this technology truly competitive. This presentation/paper asserts that combined power quality and condition monitoring, based on advanced, flexible and real-time sensing, diagnostic and controlling intelligence, can offer an effective solution for reducing operating and maintenance costs of monitored offshore network cables and related installations.
