... containing Helmholtz resonators which is deployed around a monopile in a similar method to venetian blinds. Scaled tests of the NMS at Butendiek and Luchterduinen Offshore Wind Parks showed potential for full-scale deployment. The full-scale test of the NMS was executed in the fall of 2018. A configuration...

... Abstract The conventional design methods for laterally loaded offshore foundations in sand, API RP 2GEO (2014) and DNV (2018) , were not developed for wind turbine monopiles that experience lateral loads imposing relatively small lateral displacements in service. This paper presents...

...). These models exhibit characteristic foundation behaviour such as nonlinearity, coupling of the load from different load components and hysteretic load dependent damping. This paper presents two of the REDWIN models, one applicable for monopile foundations and one for skirted suction caisson foundations. Use...

... Abstract Monopiles are the most common foundation type in the offshore wind industry. Their design is largely dependent on the ability to accurately model the soil-structure response of the foundation, with more refined modelling approaches enabling significant reductions in required embedment...

... Abstract This paper provides an overview of the PISA design model recently developed for laterally loaded offshore wind turbine monopiles through a major European joint-industry academic research project, the PISA Project. The focus was on large diameter, relatively rigid piles, with low length...

... Abstract Upon recently, most offshore foundations were based on a number of driven piles that were installed with an impact hammer. With the increase in offshore windfarms two major developments have occurred: the shift from jackets to monopiles, leading to increase of the diameter...

... A significant number of large diameter monopiles (>6 m diameter) have been installed as foundations for offshore wind turbine generators (WTG) across Northern European waters over the past decade, where the self-weight penetration (SWP) during the installation process was recorded...

... are widely used for offshore oil and gas platforms. The failure mode of these slender piles is the formation of flexural plastic hinges. In contrast, the monopiles supporting offshore wind turbines are typically rigid with 3.5 – 6 m diameter and 30 – 40 m length. The failure mode of these monopiles likely...

...). If a prediction method is used to compute the soil resistance to driving, the evaluation of pile drivability may be overly conservative. Ageing in both clay and sand should also be taken into account. Wind turbines are often supported on large diameter monopiles. The applicability of the p-y data for such large...

... Abstract Objective/Scope Offshore wind turbines (OWTs) are getting taller and heavier, and medium water depths are utilized in recent and future offshore wind farms. The increasing turbine size brings with it the increasing size of monopile foundations according to current design guidelines...
