Vertical kinematic response of monopiles subjected to vertically propagating seismic P-waves
A rigorous mathematical model is developed to analyze the kinematic response of monopiles embedded in the seabed under vertically incident P-waves. The seabed is considered to consist of nearly saturated soil, in which the mixture of pore water and ...

Validation and development of improved methods for the calculation of wave loads on XXL monopiles
Paper OMAE2018-77232, 11 S.With the offshore wind industry aiming to deploy deeper water sites (> 30 m) while still utilizing monopiles, support structures with larger diameters are required. For the design and assessment of so-called XXL monopiles, wave-

Small-displacement behavior of offshore wind power monopiles subjected to static lateral loading
The centrifuge tests and numerical simulations are carried out to explore the small-displacement behavior of 9 m-diameter offshore wind power large-scale monopiles with various embedment depths. The results show that as the embedment depth increases, the

ABSTRACT This study investigates the bearing capacity of tension piles and pile‐soil interaction during loading. Discrepancies between predicted and measured bearing capacities in previous tests motivated the study, where analytical methods showed considerable scatter and uncertainties in design.

A review of scour impacting monopiles for offshore wind
Monopiles are important structures in offshore wind engineering, primarily serving as foundations for wind turbines. When installed on a sandy seabed, local scour around monopiles can reduce their capacity, and is a significant hazard to be addressed in ...

Installation effects in the response of laterally loaded monopiles in sand - A numerical-based analysis [PDF]
The rate of construction of offshore wind turbine farms is continuously increasing, with monopiles being the extended type of foundation. During the life period of these infrastructures, the offshore environment induces lateral loads, which are ...

Computational Fluid Dynamics Study of Perforated Monopiles [PDF]
Monopiles are used in the construction of offshore wind turbines and typically have a design life of 25 to 50 years. Over their lifecycle, monopiles are exposed to a corrosive saltwater environment, facilitating a galvanic oxidation process that quickly ...

Idealized Offshore Low‐Level Jets for Turbine Structural Impact Considerations
ABSTRACT Low‐level jets (LLJs) describe conditions in which the wind speed reaches a local maximum with respect to altitude near the surface; they have been observed intermittently in the US mid‐Atlantic offshore environment. LLJs pose unique operating conditions for future wind turbines operating in the region, such as negative shear and locally ...
