Static Design for Laterally Loaded Rigid Monopiles in Cohesive Soil
Journal of Marine Science and Engineering, 2023 Rigid monopiles with small slenderness ratios (i.e., ratio of monopile embedded length to outer diameter) are widely used as foundations to resist lateral load and moment transferred from superstructures, e.g., large diameter steel pipes used by offshore

Journal of Marine Science and Engineering, 2022 Pile foundations for offshore wind turbines are subjected to large lateral loads. By mounting wings on the perimeter of regular monopiles, winged monopiles have shown better performance in resisting deformation under horizontal loading.

Installation of Large-Diameter Monopiles: Introducing Wave Dispersion and Non-Local Soil Reaction
Journal of Marine Science and Engineering, 2021 During the last decade the offshore wind industry grew ceaselessly and engineering challenges continuously arose in that area. Installation of foundation piles, known as monopiles, is one of the most critical phases in the construction of offshore wind ...

Optimization of monopiles for offshore wind turbines [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 The offshore wind industry currently relies on subsidy schemes to be competitive with fossil-fuel-based energy sources. For the wind industry to survive, it is vital that costs are significantly reduced for future projects. This can be partly achieved by introducing new technologies and partly through optimization of existing technologies and design ...

Numerical Modeling of the Monotonic Lateral Behavior of XL and XXL Monopiles in Kaolin [PDF]
, 2023 Monopiles are the favored foundation type for offshore wind turbines due to a relatively simple design and installation process. This paper investigates using coupled three-dimensional finite-element analysis the load-deformation behavior of extra-large (

Influence of scour depth and type on p–y curves for monopiles in sand under monotonic lateral loading in a geotechnical centrifuge [PDF]
, 2020 The influence of scour on the lateral response of monopile foundations for offshore wind turbines is investigated in this paper. Application of lateral load-displacement (p-y) curves to predict the lateral pile behaviour is subject to uncertainty as many

Biaxial Loading of Offshore Monopiles: Numerical Modeling [PDF]
International Journal of Geomechanics, 2017 In this study, finite-element (FE) modeling was used to examine the influence of biaxial lateral loading of a monopile foundation. Two different soil models were adopted to investigate the influence of state-dependent and anisotropic behavior of soil on monopile response.

A generic framework for reliability assessment of offshore wind turbine monopiles [PDF]
, 2017 In this work, a generic framework for reliability assessment of OWT (Offshore Wind Turbine) monopiles is developed. The framework starts with defining limit states, and four types of limit states are considered, i.e.

The turbulent wake of a monopile foundation [PDF]
Renewable Energy, 2016 Abstract An experimental programme is presented, examining the turbulent wake of a monopile foundation in a current. Velocity was recorded across an extensive domain downstream of a model monopile in a 0.5 m deep basin, using an acoustic Doppler velocimeter array. The distribution of turbulent kinetic energy (TKE) is examined across the entire domain.

Scour Reduction by Collars around Offshore Monopiles [PDF]
Scour and Erosion, 2010 Excessive scour is a threat to the stability of monopile foundations, e.g. in offshore windparks. Particularly in shallow waters with strong tidal currents such as the North Sea, protection against excessive scouring is required. Commonly applied scour protection consists of loose rock. Little is known about alternative scour protection measures.
