Journal of Marine Science and EngineeringOffshore monopile foundations endure complex loads during service. They bear vertical loads from the superstructure’s self-weight and lateral cyclic loads (e.g., wind, waves), while near-coastal seabeds are usually sloped.

Seismic Response of OWT Monopile in Clays
AbstractThe safe and stable operation of monopile offshore wind turbines (MOWTs) under seismic and environmental loading is a major challenge facing designers. A numerical method was developed for simulating the dynamic interaction of the soil-pile-structure system by employing an elastoplastic bounding surface constitutive model that can capture the ...

A qualitative study on the lateral behavior of rock-socketed monopiles
Monopile supporting offshore wind turbines (OWT) in regions with shallow rock can benefit from rock-socketing. This study qualitatively investigates the effect of the rock layer on the serviceability limit state (SLS) and the ultimate limit state (ULS ...

Installation of perforated monopiles: And the associated fatigue damage
The European offshore wind industry has experienced significant growth in the past decade, mainly focusing on shallow areas in the North Sea to reduce the Levelised Cost of Electricity (LCoE) and compete with fossil fuels.

Static capacity of laterally pre-cycled monopiles in dense sand [PDF]
, 2016 This work aims to investigate the change in static capacity of monopiles due to cyclic lateral loading. Results from small-scale tests on a monopile model in dense saturated sand are presented. Three series of tests were carried out to study the response

Development and validation of a numerical model of scour protection around monopiles under currents
, 2018 Scour around monopiles has been widely studied, however, scour protection—made of stones—around monopiles has not. To cover this knowledge gap, this work presents the development of a numerical model for the study of the flow within the scour protection ...

Response of short monopiles for offshore wind turbine foundations: virgin and post-cyclic capacity
Geotechnical centrifuge tests were conducted to examine monotonic behavior of low aspect ratio piles in soft clays. Monopiles with aspect ratio of two were tested in the 150g-ton centrifuge at Rensselaer Polytechnic Institute.
