Dynamic detection of offshore wind turbines by spatial machine learning from spaceborne synthetic aperture radar imagery

Journal of King Saud University: Computer and Information Sciences, 2022
In order to change the energy supply structure of traditional thermal power generation with excessive carbon emissions, more and more offshore wind turbines are being installed and put into operation worldwide. However, the dynamic monitoring of offshore

Detecting Loosening of Bolt‐Flanged Pipe Using Smoothed Pseudo Wigner–Ville Distribution: Digital Twin‐Based Approach Using Convolution Neural Networks

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this paper, an integrated digital twin‐based fault‐diagnosis framework is proposed to detect bolt loosening in flanged pipe connections. The approach combines finite element‐based numerical modeling, experimental modal analysis, and advanced signal processing‐assisted deep learning to achieve reliable loosening detection under operational ...

Fiber‐Reinforced Bio‐Epoxy Composites: Degradation Mechanisms in Saline Environment

Polymer Composites, EarlyView.
Constituent level degradation of bio‐epoxy composites after saline aging. ABSTRACT This study examines the degradation behavior of bio‐epoxy composites reinforced with glass, basalt, carbon, and flax fiber yarns in a simulated saline environment. Fiber yarns and composite samples were exposed to 3.5% NaCl solution at 60°C for up to 3000 h.

Study on Dynamic Response of Offshore Wind Turbine Structure Under Typhoon

Polish Maritime Research, 2022
Floating offshore wind turbines are easily affected by typhoons in the deep sea, which may cause serious damage to their structure. Therefore, it is necessary to study further the dynamic response of wind turbine structures under typhoons.

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

The reliability of wind turbines [PDF]

, 2008
The residual scepticism surrounding the installation of wind turbines, is mainly due to the perceived lack of reliability and expense of these energy converters. Because of the commercial significance of reliability, few sources of such data are publicly

Development and evaluation of an aerodynamic model for a novel vertical axis wind turbine concept [PDF]

, 2013
There has been a resurgence of interest in the development of vertical axis wind turbines which have several inherent attributes that offer some advantages for offshore operations, particularly their scalability and low over-turning moments with better ...

Renewable Resource Curse Hypothesis: Could Renewable Resources Foster Sustainable Development?

Sustainable Development, EarlyView.
ABSTRACT This study explores whether the resource curse hypothesis applies to renewable energy by introducing a novel metric of renewable resource rent. Using a panel dataset of 46 countries (2010–2022), we define renewable rent as the product of electricity generation and the gap between industrial electricity price and levelized cost (LCOE).

Stakeholder Governance of the Energy‐Biodiversity Nexus in the Renewable Energy Sector: Pathways to Achieve SDGs in the MENA Region

Sustainable Development, EarlyView.
ABSTRACT This systematic review examines stakeholder roles in managing biodiversity within renewable‐energy projects across the MENA region, a highly climate‐vulnerable region yet pursuing rapid energy transition toward achieving SDG 7 (Affordable and Clean Energy). The focus is on regulatory bodies and sector companies as primary actors.
