Purpose

The lateral tower mode on offshore turbines is generally low damped; however the damping contribution from the soil-foundation interaction is not well defined. This project will identify and analyze the important mechanisms using a FEM tool

Description

In some simulations, wave excited lateral tower vibrations results in foundation design giving high loads. These loads can be reduced to an acceptable level by just a small increase in damping. The soil-foundation interaction is considered as an unmodeled damping contributor, which may solve the problem. The aim of the project is to use advanced soil-pile modeling tools to analyze the interaction and to identify important mechanisms that can contribute with damping to the tower vibration mode.
