Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

Wind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

Tinkering Towards Sustainability: Bundling Innovations to Electrify the Fossil‐Dependent Process Industry

Creativity and Innovation Management, EarlyView.
ABSTRACT Sustainability transitions, such as electrifying the process industry, require a bundle of related innovations to make meaningful progress. Drawing on literature on innovation through tinkering, that is, adaptive, typically small‐scale experimentation with various forms of innovation, and applying a micropolitical perspective, this qualitative

Reliability analysis of mooring chains for floating offshore wind turbines

Frontiers in Built Environment
As offshore wind farms move into deeper waters, around 80 m, the high costs necessitate replacing bottom-fixed turbines with floating offshore wind turbines, which require mooring systems to maintain stability within design limits.

Platform Optimization and Cost Analysis in a Floating Offshore Wind Farm

Journal of Marine Science and Engineering, 2020
Floating offshore wind represents a new frontier of renewable energies. The absence of a fixed structure allows exploiting wind potential in deep seas, like the Atlantic Ocean and Mediterranean Sea, characterized by high availability and wind potential ...

The Comparative Political Economy of the Green Transition: Economic Specializations and Skills Regimes in Europe

Regulation &Governance, EarlyView.
ABSTRACT The green transition is fundamentally transforming contemporary economies and societies. This article investigates how European models of capitalism perform and specialize across the green value chain—conceptualized as innovation, manufacturing, services, and deployment—and how national skill formation systems underpin these specializations ...

Determination of stress concentration factors in offshore wind welded structures through a hybrid experimental and numerical approach [PDF]

, 2019
Offshore wind turbine (OWT) monopile support structures generally consist of steel cans connected together through circumferential welding joints. One critical factor to evaluate the localised increase in stresses is the stress concentration factor (SCF)

Segmented Gurney Flaps for Improved Wind Turbine Wake Recovery

Wind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT When wind passes through the rotor of a wind turbine, the velocity is decreased while turbulence is increased. The region of decreased wind speed behind the rotor is known as the wind turbine wake and is bounded by a complex structure of helical vortices. This structure occurs to be more stable in low ambient turbulence and low tip speed ratio
