Special Issue Information

Dear Colleagues,

Ensuring access to affordable, reliable, sustainable and modern energy for all is one of the 17 Sustainable Development Goals (SDGs) defined by the United Nations General Assembly (UN-GA) in 2015. To achieve this goal requires, among other things, the fast and sustainable development of offshore wind energy in the world. In the past three decade, offshore wind has experienced a tremendous capacity growth, thanks to an astonishing reduction of levelized cost of energy (LCOE) through technological advancements and industrial developments. However, focusing on LCOE alone has become more and more inadequate for the future development of offshore wind. As the share of offshore wind increases further in the energy mix, the sustainability of offshore wind itself and its contribution to the sustainability of the society in general need to be more closely examined and constantly improved.

In light of the above, this special issue, entitled with “Current Advances in Offshore Wind Energy for Sustainability”, aims to present studies that address the important topic of offshore wind energy for sustainability. Furthermore, with this special issue, we hope to foster the exchange of ideas from different perspectives and inspire more research and innovations in the field of offshore wind energy with sustainability as an essential objective. Ultimately, this will help to make offshore wind an important player in the sustainable future energy system.

Contributions to this Special Issue are expected to bring new knowledge and insights to offshore wind energy for sustainability. Themes include but are not limited to the following topics of offshore wind energy:

  • Life cycle assessment
  • Environmental impacts
  • Social impacts and acceptance
  • Planning and regulations
  • Energy policies and economics
  • Recycling and circular economy
  • New materials and innovative designs
  • Wind farm siting and design
  • Operation and maintenance
  • Power-to-X and hybrid energy systems
  • Integration and power system

I look forward to receiving your contributions.

Offshore substations are important sustainable power infrastructures subjected to strong vibrations induced by complex environmental excitations such as wind, waves, and currents. To protect the structures and expensive facilities, lightweight vibration control devices are highly desirable in offshore substations. With a high-performance energy dissipation device, the inerter, the conventional Tuned Mass Damper (TMD) is upgraded for lightweight vibration control. The optimal parametric design and performance evaluation of single- and double-tuned vibration control devices is performed based on the H-norm criteria. The corresponding equivalent mass ratios of both single- and double-tuned vibration control devices are summarized and formulated in a systematical manner. Finally, the presented optimal design formulas, equivalent mass ratios, and control performances are validated by vibration control analyses on a practical offshore substation. The results show that inerter-based vibration control devices can be effectively equivalent to a TMD, with the equivalent mass ratio. The double-tuned inerter-based device could save 25% mass compared to a TMD. With a Tuned Mass Damper Inerter (TMDI), the responsibility for the mass could be shared with dual-end connected inerters. Meanwhile, the Tuned Viscous Mass Damper (TVMD) completely replaces the mass block with an inerter, which has a superior lightweight vibration control performance. Full article

The present study aims to address the knowledge gaps in dynamic power cable designs suitable for large floating wind turbines and to develop three baseline power cable designs. The study includes a detailed database of structural and mechanical properties for three reference cable models rated at 33 kV, 66 kV, and 132 kV to be readily used in global dynamic response simulations. Structural properties are obtained from finite element method (FEM) models of respective cable cross-sections built in UFLEX v2.8.9—a non-linear stress analysis program. Extensive mesh sensitivity studies are performed to ensure the accuracy of the predicted structural properties. The cable’s structural design is investigated using global response simulations of an OC3 5MW reference wind turbine coupled with the dynamic power cable in a lazy wave configuration. The feasibility of the present reference cable in floating offshore wind applications is assessed through a simplified analysis of cable fatigue life and structural integrity analysis of the cable in extreme environmental conditions. The analysis results suggest that the dynamic power cable does not significantly affect the response characteristics of the floating wind turbine in the analyzed lazy wave configuration. Furthermore, a simplified fatigue analysis demonstrates that the proposed cable design can sustain representative environmental loading scenarios and shows favorable dynamic performance in a lazy wave configuration.

Despite the vast potential of wind energy, it has yet to be implemented widely in Bangladesh. Several barriers play major roles in obstructing the wind energy sector’s development in Bangladesh. Hence, it is necessary to identify these barriers to progress this sector’s growth. The analytic hierarchy process (AHP) is a multi-criteria decision-making method that can rank alternatives by considering multiple factors. It is a valuable tool for complex decision-making problems with multiple criteria, and their relationships must be clarified. So, in this analysis, AHP is used to rank the barriers related to wind energy development in Bangladesh. First, six main barriers and eighteen sub-barriers have been identified from a detailed and comprehensive literature review. The main barriers are categorized into technical, administrative, policy and political, economic, social, and geographic. After that, a questionnaire was sent to experts to obtain their opinions on these barriers. Based on the analysis, it was found that, with a weighted score of 0.46, technical barriers were the most significant ones. Administrative barriers ranked second with a weighted score of 0.21, and social barriers ranked last with a weighted score of 0.03. Among the sub-barriers, risks associated with technology were found to be the most significant, while land use conflict was found to be the least significant. Finally, several recommendations are provided to overcome the wind energy barriers in Bangladesh. The findings of this study can help policymakers and stakeholders develop strategies to overcome the barriers to wind energy development in Bangladesh. Full article
