Context. Over 55% off all insurance claims to offshore wind farms are incurred by damaged cables and foundations. Moreover, the severity of these failures and associated repair costs result that these claims represent more than 90% of the total claims. Online monitoring is seen by the offshore wind industry as one of the main solutions to decrease the number of damages in cables and foundations, through their early detection and identification. Fiber optic technology is chosen as the preferred monitoring technique as it is very versatile (i.e. sensitive to temperature, strain, impact, partial discharge activity, …). The wide application of fibre optic sensing, however, lacks maturity as only temperature sensing on cables (DTS technology) and strain sensing on foundations (FBG technology or classical strain gauge technology) is common practice in offshore wind.
Goals. The BOPTIC project will address the need of offshore wind developers and operators to reduce the operational expenses of the Balance of Plant (BOP) by the development of innovative monitoring technologies for both the cables and foundations using emerging distributed optical sensing technologies. This research project wants to investigate in depth how to use distributed optical sensing techniques to:
(1) Monitor strain and bending in offshore power cables during installation and operation
(2) Monitor strain and bending moments of monopiles with high spatial resolution during their lifetime for hotspot location and seabed evaluation
(3) Detection and Monitoring of electrical faults of an offshore power cable during operation.
(4) Detection and Monitoring of cracks on welds of offshore structures during their lifetime
This project is initiated by 9 different stakeholders of the Blue Energy including 3 research institutions: Marlinks, 24Sea, ENGIE Laborelec, IMDC, Com&Sens, Parkwind, OCAS, VUB and UGent. Laboratory Soete of UGent will be mainly involved in tasks related to goals (1) and (4).
Concretely, we will contribute to the following activities:
