Steel Jackets and Monotower Foundations for Offshore Wind Turbines
Volume 1: Offshore Technology, 2012Steel jacket support structures for offshore wind have an increasing popularity for water depths larger than 20 m. Traditionally, support structures such as monopiles and gravity based foundation have dominated at shallow water. Offshore wind industry deals gradually with larger water depths, and light weight foundations as steel jackets are believed ...

Structural And Installation Design Of Plate Foundations For Jackets
Offshore Technology Conference, 1994ABSTRACT A new foundation system for offshore steel jackets has been developed by Statoil. The method is called plate foundations and it replaces the use of traditionally piled foundations. The plate foundation consists of a circular plate placed below each jacket leg.

Ultimate lateral bearing capacity of tetrapod jacket foundation in clay
Computers and Geotechnics, 2017Abstract The tetrapod jacket foundations that are always used to support offshore wind turbines have been investigated primarily in laboratory experiments. In this study, the ultimate lateral soil resistance on this type of foundation was investigated using the finite element method and the analytical upper bound plasticity method.

DAMAGE DETECTION ON OFFSHORE WIND TURBINE JACKET FOUNDATIONS BASED ON AN AUTOENCODER
Proceedings of the 13th International Workshop on Structural Health Monitoring, 2022This work addresses the problem of damage detection on offshore wind turbine jacket-type foundations based on deep learning algorithms. The work utilizes data obtained from the vibration response of a lab-scale wind turbine foundation. The main contributions of this manuscript to damage detection are: (i) an autoencoder neural network trained with only

Efficient response recovery procedures for detailed design of jacket foundations
2016Two efficient system reduction procedures for detailed design of jacket foundations by post-processing of aero-elastic simulation results based on reduced structural models (superelements) are presented. It is illustrated that the full foundation response can be accurately recovered either via a force-controlled approach where the interface forces from

Influence of foundation model complexity on the design loads for offshore WTG on jacket foundation
2013The present work investigates the influence of using different ways of interfacing wind turbine model and foundation on loads in the combined structure. In the design procedure for offshore wind turbines it is common that foundation and wind turbine design loads are obtained in two sequential steps where firstly; the wind turbine designer defines the ...

Centrifuge and DEM modelling of helical piles for offshore jacket foundations in sand
9th International SUT Offshore Site Investigation Geotechnics Conference Proceedings “Innovative Geotechnologies for Energy Transition”Two of the main challenges for the design of offshore wind turbine foundations are the need for silent installation techniques and for large tensile capacity. Helical piles, composed of one or several helices connected to a steel shaft can meet both challenges.
