Reliability of floating foundation concepts for vertical axis wind turbines [PDF]

, 2010
Offshore wind turbines are developing at a rapid pace. By far the most common turbine configuration is the HAWT (Horizontal Axis Wind Turbine) and development of these machines is largely centered about drive train and blade issues with some work ...

Sensitivity analysis of design parameters for reliability assessment of offshore wind turbine jacket support structures

International Journal of Naval Architecture and Ocean Engineering, 2022
Offshore Wind Turbine (OWT) support structures are subjected to hostile environments, defined by highly stochastic loads and complex soil-structure interaction, and thus the need for a probabilistic approach towards design.

Distributed plasticity approach for the nonlinear structural assessment of offshore wind turbine

International Journal of Naval Architecture and Ocean Engineering, 2020
This study provides an insight of the nonlinear behavior of the Offshore Wind Turbine (OWT) structure using the distributed plasticity approach. The fiber section beam-column element is applied to construct the finite element model.

Simplified Calculation Method for the Natural Frequencies of the Offshore Wind Turbine Structures with Monopile Foundations Based on Euler–Bernoulli Beam Theory

Advances in Civil Engineering, 2023
The wind and wave loads on the offshore wind-turbine (OWT) structures with monopile foundations occur at specific frequencies. When these excitation frequencies are close to the natural frequencies of OWT structures, resonance can disturb the proper ...

Movement pattern of red seabream Pagrus major and yellowtail Seriola quinqueradiata around Offshore Wind Turbine and the neighboring habitats in the waters near Goto Islands, Japan

Aquaculture and Fisheries, 2021
We investigated movement pattern of commercial important fish around Offshore Wind Turbine (OWT) and neighboring habitats in Goto Islands. We tagged 55 individuals of 2 fish species and released around the OWT in 2017.

On local stress distributions in impact‐loaded Offshore Steel Substructures

ce/papers, Volume 9, Issue 2-3, Page 2826-2830, September 2026.
Abstract The global energy transition necessitates a significant expansion of offshore wind energy. To ensure long‐term operational efficiency, offshore wind turbines (OWT) require regular maintenance by specialized crews. The crew is transferred via Crew Transfer Vessels (CTV), which land at the boat landing, generating substantial impact loads.
