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 ...

A model test study on the parameters affecting the cyclic lateral response of monopile foundations for offshore wind turbines embedded in non-cohesive soils [PDF]
Wind Energy Science, 2022 During their service life, monopiles supporting offshore wind turbines are subjected to a large number of lateral cyclic loads resulting from complex environmental conditions such as wind and waves varying in amplitude, direction, load eccentricity and ...

Tsunami-induced scour around monopile foundations [PDF]
Coastal Engineering, 2017 Abstract A fully-coupled (hydrodynamic and morphologic) numerical model is presented, and utilized for the simulation of tsunami-induced scour around a monopile structure, representative of those commonly utilized as offshore wind turbine foundations at moderate depths i.e. for depths less than 30 m.

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.

Scour Protection around Offshore Wind Turbines: Monopiles [PDF]
Scour and Erosion, 2010 The flow processes in a scour protection around a mono-pile in steady current is described in relation to transport of sediment in the scour protection based on physical model tests. Transport of sediment in the scour protection may cause sinking of the scour protection. This may reduce the stability of the mono-pile and change for instance the natural

Evaluation of sand p–y curves by predicting both monopile lateral response and OWT natural frequency
Studia Geotechnica et Mechanica, 2022 Extending the use of the p–y curves included in the regulation codes API and DNV to design large-diameter monopiles supporting offshore wind turbines (OWTs) was unsuccessful as it resulted in an inaccurate estimation of the monopile behavior.

An approach for 2D modelling of laterally loaded piles
Soils and Foundations, 2023 Despite a considerable progress in the analysis and design of monopiles, many methods are based on complex mathematical structures with doubtful or hard assumptions to verify.

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.

Liquefaction analysis of soil plugs within large diameter monopiles using numerical modelling
Bulletin of Earthquake Engineering, 2023 Soil plug formation in open-ended piles due to pile driving is a widely studied phenomenon in onshore applications. The narrow diameters of traditional onshore piles ranging from 0.5 to 1.5 m facilitate plug generation during installation and transfer of
