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.

Analysis of lateral bearing capacity of wing-monopile with symmetrical wing plates
Shuili Shuiyun Gongcheng Xuebao, 2020 There are many factors that affect the lateral bearing capacity of wing-monopile, among which the number of wing plates, the angle between load direction and wing plates are the main influencing factors. The ABAQUS finite element calculation software was

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.

Shuili Shuiyun Gongcheng Xuebao, 2023 Scour is one of the key factors that should be considered in the design process of offshore wind turbine (OWT) monopile foundations. However, the geometry of local scour pit and embedded length-to-diameter ratio of pile (L/D) are always ignored in ...

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.

Applied Sciences, 2023 Offshore Wind Turbines (OWT) with increasingly higher energy output are being developed to meet energy demands, posing greater challenges for their foundation design. Several foundation types are used to support these turbines, with monopiles (MPs) accounting for 80% of the installed capacity.

Active vibration control of a monopile offshore structure [PDF]
Journal of Structural Control, 1999 Abstract In the Danish part of the North Sea monopile platforms with a cylindrical shaft have been used at the exploitation of marginal fields. In the paper a new principle for active vibration control of such structures is suggested.
