NUMERICAL MODELING OF BACKFILLING PROCESS AROUND MONOPILES [PDF]
Coastal Engineering Proceedings, 2014 This study presents a three-dimensional (3D) numerical modeling study on the backfilling process around monopiles. The numerical model utilized in the study is based on that given by Jacobsen (2011). It is composed of two main modules. The first module is the hydrodynamic model where the fluid flow conditions around the structure and near the bed are ...

Centrifuge modelling of offshore monopile foundation [PDF]
, 2010 Today one of the most used concepts for wind turbine foundation is the monopile. The foundation concepts for these monopiles on deeper water is uncertain and consequently the design needs to be conservative leading to uneconomic designs. This paper describes a total number of 6 static and 5 cyclic centrifuge tests on a laterally loaded monopile in dry ...

In situ mortality experiments with juvenile sea bass (Dicentrarchus labrax) in relation to impulsive sound levels caused by pile driving of windmill foundations. [PDF]
PLoS One, 2014 Impact assessments of offshore wind farm installations and operations on the marine fauna are performed in many countries. Yet, only limited quantitative data on the physiological impact of impulsive sounds on (juvenile) fishes during pile driving of ...

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 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 ...

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

Yantu gongcheng xuebao, 2023 The response characteristics of large-diameter monopiles under static and dynamic loads are obviously different from those of traditional small-diameter piles.

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.

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.

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.
