Effect of nearby strip loading on lateral capacity of offshore large-diameter monopiles in clay slope

Marine Georesources & Geotechnology, 2022
This study is devoted to investigating the effect of nearby strip loading on the lateral bearing capacity of offshore large-diameter monopiles at the crest of marine clay slope by the finite element limit analysis (FELA) method.

Effect of loose sand layers within dense sand on the lateral capacity of extra-extra-large monopiles

Marine Georesources & Geotechnology
A series of 3D finite element analyses were performed to examine the influence of loose sand layers on the monotonic lateral capacity of an extra-extra-large semirigid monopile in dense sand.

Field experiments on instrumented winged monopiles

Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2016
This paper presents the results of field tests performed to investigate the field behaviour of winged-monopile foundations. The principle of the winged monopile is that steel plates are attached to a standard monopile (in the area near the ground or seabed surface) to increase the foundation stiffness and lateral resistance.

Corrosion of the interior steel surfaces of offshore monopiles

Ships and Offshore Structures, 2022
The present paper reports on four-year field investigations aimed at ascertaining internal corrosion rates for offshore wind-power generation monopiles, despite these being designed to obviate internal corrosion through oxygen exclusion. Results for mild

A p–y Model for Large Diameter Monopiles in Sands Subjected to Lateral Loading under Static and Long-Term Cyclic Conditions

, 2021
The design of large diameter monopiles subjected to cyclic lateral loading is of interest in many applications, such as, for example, in the offshore wind energy industry.

Deflection of Monopiles with Collar Caissons

Journal of the Geotechnical Engineering Division, 1981
The discovery of small reserves of gas does not, in general economically justify the investment required for construction of conventional offshore platforms. In this context, the development and economic advantages of monopode platforms for drilling and producing gas wells, in water depths of the order of 100 ft (30 m).

Observed variations of monopile foundation stiffness

2015
The soil-structure stiffness of monopile foundations for offshore wind turbines has a high impact on the fatigue loading during normal operating conditions. Thus, a robust design must consider the evolution of pile-soil stiffness over the lifetime of the wind farm.
