Special Issue Information

Dear Colleagues,

The recent worldwide success of offshore wind turbines has demonstrated that harvesting vast offshore renewable energy is instrumental in achieving ambitious Net Zero targets. In this regard, the progress made by the offshore wind industry in terms of significant capital cost reduction is expected to be followed by other renewable energy solutions, such as wave, tidal and solar, integrated with other energy vectors such as hydrogen and ammonia. However, there are serious engineering challenges, especially concerning the structural integrity performance of these high-value assets due to harsh environmental conditions, massive mechanical loading caused by the ever-increasing size of energy converters, and costly maintenance activities to tackle degradation issues. Nevertheless, advanced manufacturing techniques, materials, sensing technologies, and decision support systems empowered by artificial intelligence development present opportunities.

In light of the challenges and opportunities mentioned above, we launch the Special Issue titled “The Safety and Reliability of Offshore Energy Assets”. The issue aims to collect original and impactful papers presenting theoretical, analytical, empirical, and numerical studies which enhance our understanding of structural integrity issues affecting the safety and reliability of these assets and provide practical engineering solutions to these issues to achieve optimal design and structural integrity management. Review papers that provide a critical view of the latest developments in methods, modelling, and analysis are also encouraged.

This Special Issue covers a wide range of structural safety and reliability-related topics such as fatigue, fractures, environment-assisted cracking, the loss of ultimate load carrying capacity, and buckling. Moreover, studies investigating the impact of advanced materials and manufacturing on the structural integrity performance of offshore renewable structures are highly encouraged. Finally, studies adopting state-of-the-art risk-based methodologies to tackle issues with respect to structural design, maintenance planning, and life extension are also most welcome.

Material selection is a crucial aspect in the design of reliable, efficient and long-lasting wave energy converters (WECs). However, to date, the development of tailored methodologies applied to the material selection of WECs remains vastly unexplored. In this paper, a material selection framework for the case of lift-based WECs is developed. The application of the methodology is demonstrated with the hydrofoils of the device. Offshore steel, high-strength offshore steel, aluminium alloys, and carbon- and glass-fibre-reinforced composites are considered and evaluated subject to relevant criteria for wave energy converters, namely structural reliability, hydrodynamic efficiency, offshore maintainability, total manufacturing cost and environmental impact. Candidate materials are assessed via fuzzy TOPSIS for three scenarios of the life cycle of the WEC: conceptual, commercial and future projection stages. Results show that the choice of optimal materials could change from present to future and that multi-criteria decision-making tools aided by a fuzzy approach are useful design tools for novel WECs when field data are scarce. Hence, methodologies such as the ones presented in this work can help in reducing the probability of mechanical failures of emerging WEC technology. Full article

This comprehensive review explores the application and impact of digital twin (DT) technology in bolstering the reliability of Floating Offshore Wind Turbines (FOWTs) and their supporting platforms. Within the burgeoning domain of offshore wind energy, this study contextualises the need for heightened reliability measures in FOWTs and elucidates how DT technology serves as a transformative tool to address these concerns. Analysing the existing scholarly literature, the review encompasses insights into the historical reliability landscape, DT deployment methodologies, and their influence on FOWT structures. Findings underscore the pivotal role of DT technology in enhancing FOWT reliability through real-time monitoring and predictive maintenance strategies, resulting in improved operational efficiency and reduced downtime. Highlighting the significance of DT technology as a potent mechanism for fortifying FOWT reliability, the review emphasises its potential to foster a robust operational framework while acknowledging the necessity for continued research to address technical intricacies and regulatory considerations in its integration within offshore wind energy systems. Challenges and opportunities related to the integration of DT technology in FOWTs are thoroughly analysed, providing valuable insights into the role of DTs in optimising FOWT reliability and performance, thereby offering a foundation for future research and industry implementation.
