MooringSense objectives

MooringSense aims at reducing Floating Offshore Wind operational costs by 10-15% and increasing operational efficiency by means of an Annual Energy Production increase by 2-3%.These objectives will be obtained through the development of more efficient strategies and tools for mooring system integrity management and control. MooringSense will take advantage of mooring systems’ updated condition information, provided by innovative Digital Twin and monitoring technologies, to allow the implementation of risk-based integrity management plans and more holistic control strategies, leading to reduced OPEX and increased energy production in Floating Offshore Wind Farms.

MooringSense development will benefit from the O&G industry cumulated knowledge and experience in the fields of mooring systems’ design, manufacturing, and Operation and Maintenance (O&M) (including monitoring and inspection technologies), as well as, digital twinning of offshore assets.

MooringSense will comprise the development and validation of innovative solutions (enablers) coming from multiple disciplines from numerical modelling and simulation, to Global Navigation Satellite System (GNSS), SHM, and up to control systems. These enablers imply the following specific objectives:

  • Digital Twin of Floating Offshore Wind Turbine mooring systems. High fidelity numerical models will be developed, calibrated and validated in an Ocean Basin Laboratory to obtain a TRL 4 prototype. These models will provide high accuracies in mooring line tension predictions.
  • Robust low-cost self-contained smart sensor for motion measurement. A prototype will be developed and validated with experiments involving a relevant environment to reach TRL 5

    . The developed sensor will be at least one order of magnitude cheaper than current technologies.

  • SHM system for early stage fault detection. A TRL 5 prototype will be developed by making an extensive use of data obtained through simulations, and also through experimentation in a relevant environment.
  • More efficient strategies for the Integrity Management of the Mooring Systems. A risk-based inspection methodology will be developed, as well as control algorithms, to manage optimally the Remaining Useful Life of the mooring systems. A prototype of this holistic approach will be developed and validated in lab (i.e. water tank) and through simulations to reach TRL 4. Inspection costs like in bottom fixed solutions (i.e. jackets) and 10% lifespan extension will be achieved.
