Integrated condition monitoring for subsea power cable systems

Due to the drive for renewable energy, offshore generation schemes are planned and constructed at an increasing rate. Due to the high cost of repairing subsea cables and the onerous installation and operating conditions, monitoring of the cable can be used as an effective asset management tool. By having reliable and continuous asset condition monitoring system, preventative maintenance and condition based maintenance can deliver large savings. Finite element modelling and pre-sanction engineering can be used to establish how effective the monitoring can be and also calibrate the models against actual conditions.
