Floating wind is set to develop offshore, where winds are more intense and regular and interactions with other activities are more limited. The next French calls for tenders will concern areas that are relatively far from the coast, which will make offshore electricity substations on piles difficult to envisage from an economic point of view. It is therefore essential to accelerate the development of floating substations, in particular with in-service monitoring of electrical and mechanical components in order to optimise the costs associated with the operation and maintenance phases.
To develop and demonstrate a comprehensive methodology for in-service electrical and mechanical monitoring of floating offshore electrical substations
- Gathering feedback on the operation and maintenance of electrical substations with and without in-service monitoring, defining specific requirements for optimising OPEX
- Identification of the risks of failure of offshore substations and the degradation processes of certain components, then development of a global methodology for optimised electrical and mechanical maintenance
- Demonstration of this methodology at system level on the basis of 5 case studies (inspection and/or in-service monitoring at various frequencies and degrees) including different scenarios, on 3 different sites (North Pacific, North Atlantic and Mediterranean)
MOSISS developed robust tools for defining an optimised maintenance strategy for any complex system, based on a combination of inspections and in-service monitoring.
