A macro-element for integrated time domain analyses representing bucket foundations for offshore wind turbines
(Peer reviewed; Journal article, 2018)The paper presents a macro-element model for bucket foundations to be used in integrated time domain analyses of offshore wind turbines. The macro-element has been formulated in the multi-surface plasticity framework, and ... -
A multi-spring model for monopile analysis in soft clays
(Peer reviewed; Journal article, 2020)The offshore wind industry in China has seen a rapid development in recent years and is projected to account for half of global yearly installed capacity in the years to come. Monopiles are a popular foundation solution ... -
A procedure for predicting the permanent rotation of monopiles in sand supporting offshore wind turbines
(Peer reviewed; Journal article, 2020)Foundations for Offshore Wind Turbines (OWTs) are designed following the limit state philosophy. One of the considered states is the Serviceability Limit State (SLS), which verifies that the permanent rotation of the ... -
Estimation of natural frequencies and damping using dynamic field data from an offshore wind turbine
(Peer reviewed; Journal article, 2020)The dynamic characteristics of offshore wind turbines are heavily affected by environmental loads from wave and wind action and nonlinear soil behaviour. In the design of the monopile structures, the fatigue load due to ... -
Impact of foundation modelling in offshore wind turbines: Comparison between simulations and field data
(Journal article; Peer reviewed, 2019)The design of Offshore Wind Turbines (OWTs) relies on integrated simulation tools capable of predicting the system dynamic characteristics and the coupled loads and responses. Despite allefforts to develop accurate integrated ... -
