Project Details

Description

Background
Nowadays, the offshore wind market is moving towards wind
farms with higher capacity generators and in deeper waters to increase energy
production, with the consequence of deploying deep offshore designs. In the
years to come, the offshore wind market will require advanced models to reduce
the cost of jacket foundations for offshore wind turbines. Therefore, it is
required to improve the investigation of the dynamic response of jacket
foundations.
Project
The main goal of this project is to develop a numerical model to capture
the dynamic response of jacket foundations of offshore wind turbines, accounting
for the soil-pileinteraction, soil properties and pile geometry.
Perspective











It is supposed to implement
soilelasto-plastic constitutive model in a numerical finite element code. Developing
a lumped parameter model to represent the soil and the foundation is also
attempted.
