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

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.

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 ...

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 ...
