Remaining useful life of moorings and
umbilicals for offshore renewables
Project funded by the Department of Industry, Energy Transition and Sustainability of
the Basque Government (ELKARTEK 2024 Programme)

Context

The increase in the unit power of devices used in offshore renewable energy presents the challenge of withstanding significantly higher structural loads. In addition, wind farms are being installed at increasing distances from the coast and in deeper waters, making it essential to develop floating technologies capable of adapting to these extreme conditions. Furthermore, the marine environment introduces additional complexities, such as the high costs of accessing assets and the significant economic impact of any failure that disrupts energy production.

Artificial Intelligence (AI) offers promising results in modelling degradation; however, it requires extensive datasets, such as long time series of up to 20 years, to estimate the lifespan of these devices. Additionally, data-driven approaches often lack generality and are typically applicable to a single project. Moreover, in the renewable energy sector, decision-making is based not only on economic criteria but also on the reliability of components.

Challenge

RUL-ET focuses on developing new AI-based approaches and building datasets for estimating the Remaining Useful Life (RUL) of moorings and umbilicals in offshore renewable technologies.

Its strategic objective is to research the critical elements of the floating renewable energy value chain in the marine environment, aiming to generate knowledge that enables a paradigm shift in determining the lifespan of components. This aims to:

  • Reduce uncertainty in failure prediction and the remaining life of moorings and dynamic cables.
  • Develop more accurate predictive maintenance strategies.
  • Reduce operational costs.

Expected results

  • 1 USEFUL DATA LIBRARY for the estimation of RUL of moorings and umbilical cables
  • 1 SOFTWARE LIBRARY for structural health diagnosis
  • 3 SOFTWARE MODELS
    • Life prediction
    • Uncertainty management
    • Support for maintenance decision-making
  • 4 APPLICATION EXAMPLES: Complete definition of the use cases (moorings and umbilicals) and comprehensive characterisation of two contexts (base and derived locations).

Research areas

Project partners

These are the entities of the Basque Network of Science, Technology and Innovation that collaborate in the development of AI-based approaches and in the creation of datasets to estimate the remaining useful life of moorings and umbilicals in offshore renewable energy.

Advisory Board

The Advisory Board is an external body that guides the project, consisting of experts and key representatives. Its role is to steer developments towards business needs, analysing progress and providing feedback and perspectives on the matter.
