Monopiles für die Energiewende Taiwans

UmweltMagazin, 2021
Ein niedersächsischer Windkraftanlagenbauer lieferte 2020 erstmals Fundamentpfähle (Monopiles) für Offshore-Windräder nach Taiwan. Sie sind bis zu 95 m lang und bis zu 1 750 t schwer Der Auftrag verlief erfolgreich. Das Unternehmen erhofft sich jetzt weitere Aufträge aus Asien.

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.

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.

Improved Pile Installation Predictions for Monopiles

2019
As the world transitions toward more sustainable energy sources, there is an increased interest in renewables, with offshore wind well placed to provide significant grid-scale input. Historically, a key limitation has been the cost, with the first offshore wind farms in Europe costing $175 to $250 per megawatt-hour (MWh).

Geotechnical Design Considerations for Offshore Monopiles

2013
The choice of the foundation for offshore structures is influenced by a number of considerations including the site conditions and loading characteristics. At water depths of up to 25m the most common foundation type is monopiles, which are single steel pipe piles driven open-ended into the soil.

The Reverse Approach for Monopile Scour

2012
The present paper deals with the theoretical and numerical modeling of scouring and backfilling around an offshore monopile. Based on existing relations for the bed load and the bed update, and a new model for the sediment pickup, it demonstrates the possibility of computing the mean bed shear stress if the bed and bed update is estimated.
