Gentle Driving of Piles (GDP) at a sandy site combining axial and torsional vibrations: Part II - cyclic/dynamic lateral loading tests

Gentle Driving of Piles (GDP) is a new technology for the vibratory installation of tubular (mono)piles. Its founding principle is that both efficient installation and low noise emission can be achieved by applying to the pile a combination of axial and torsional vibrations. Preliminary development and demonstration of the proposed technology...

Frequency effects in the dynamic lateral stiffness of monopiles in sand: insight from field tests and 3D FE modelling

With the offshore wind industry rapidly expanding worldwide, geotechnical research is being devoted to foundation optimisation - most intensively for large-diameter monopiles. The analysis and design of monopiles still suffers from significant uncertainties in relation to cyclic/dynamic loading conditions. The aim of this work is to shed new...

Geotechnical aspects of offshore wind turbine dynamics from 3D non-linear soil-structure simulations

The development of the offshore wind industry is motivating substantial research efforts worldwide, where offshore wind turbines (OWTs) of increasing size are being installed in deeper water depths. Foundation design is a major factor affecting the structural performance of OWTs, with most installations founded to date on large-diameter...

Geotechnical Aspects of Offshore Wind Turbine Dynamics Emerging from 3d Sand-Monopile Non-Linear Simulations

In recent years, offshore wind is becoming an increasingly growing market in Europe. Many resources are allocated towards ensuring its sustainable progress while one of the biggest uncertainties encountered lays in the offshore wind turbine's (OWT) foundations. In Europe, monopiles are the most widely adopted solution to found such structures in...
