Assessment of foundation design for offshore monopiles unprotected against scour
Ocean Engineering, 2013When designing offshore monopiles without scour protection, the stiffness of the foundation will vary with time due to the dependency of the scour depth on current and sea conditions. Currently, design regulations of organizations such as Det Norske Veritas (DNV) and the International Organization for Standardization (ISO) recommend the use of the most

A novel hybrid monopile foundation for offshore wind turbines
Ocean Engineering, 2020Abstract This paper presents a hybrid monopile foundation for offshore wind turbines. It is an ultra-high performance concrete-filled double skin steel tubular structure (CFDST) used as a replacement of the conventional steel tube between the water level and the mudline so as to reduce the monopile diameter and thereby reducing the wave loads on the ...

Transient analysis of monopile foundations partially embedded in liquefied soil
Geomechanics and Engineering, 2015In this study, the authors present a coupled fluid-structures-seabed interaction analysis of a monopile type of wind turbine foundations in liquefiable soils. A two dimensional analysis is performed with a nonlinear stiffness degradation model incorporated in the finite difference program Fast Lagrangian Analysis of Continua (FLAC), which captured the ...

Ship collision analysis on offshore wind turbine monopile foundations
Marine Structures, 2017Abstract An offshore wind farm can be located close to traffic lanes of commercial and passenger ships, which may lead to possible collision. The work presented in this paper aims to understand both the crushing behaviour and the nacelle dynamics of a monopile offshore wind turbine when impacted by a ship.

Behavior of monopile foundations under cyclic lateral load
Computers and Geotechnics, 2009Abstract This paper describes the development and application of design charts for monopile foundations of offshore wind turbines in sandy soil under long-term cyclic lateral load. It outlines a numerical model, working with a numerical concept, which makes the calculation of accumulated displacements based on cyclic triaxial test results possible ...

Corrosion and biofouling of offshore wind monopile foundations
2020The impact of corrosion and biofouling on offshore wind turbines is considered to be a key issue in terms of operation and maintenance (O&M) which must be better addressed. Early design assumptions for monopile foundations anticipated low, uniform corrosion rates in a sealed compartment that would be completely air- and water-tight.

Analysis of Monopile Foundation for Offshore Wind Turbine
2016Load deformation characteristics of monopile are being analyzed in the project. As monopile is a supporting structure for offshore wind turbines. Due to varying environmental conditions exact prediction of load value is not possible but it is important to analyze the load vs deformation relationships to see the behavior of monopile.
