Foundation Design of Offshore Wind Structures
The course will start by providing an overview of wind farms and the support structures necessary for foundation design. Following this, the main offshore loads will be considered as well as the calculations required. The third part of the course will look at geotechnical investigations and soil structure interaction issues related to foundation design before finishing with some hand calculation methods together with example applications & Case Studies from Europe and China
Throughout the day, examples, case studies and practical considerations will be used to consolidate the knowledge gained by the attendees and gauge their understanding, leaving delegates with a more rounded appreciation of the foundation design
Overview of Offshore wind farms
The course will begin with an overview of offshore wind farms (Energy challenge, Overall farm layout, Site Selection criteria & constraints, Impact of Geology) before looking at the specifics of turbines and wind turbine support structure that are necessary for foundation design. Lastly will be an outline of the challenges in design and construction of support structures for larger turbines in deeper waters.
Loads on offshore wind turbine foundations & Calculations necessary
This section will start by looking at the loads on offshore wind turbine foundations (monopile, jacket/multiple support & floating) including seismic considerations before examining the calculations necessary for foundation design & design criteria (Limit States etc).
Soil-Structure Interaction issues & Site Investigations required
The third part of the course will introduce soil-structure Interaction issues (cyclic & dynamic) related to foundation design, Damping issues, site Investigations required, & cyclic/advanced element testing of soil
Hand calculation methods & Case Studies
The course will close with an overview of hand calculation methods together with example applications & Case Studies from Europe and China . The methods will focus on:
1. Obtaining foundation stiffness for a given foundation and ground profile,
2. Natural frequency estimations for different systems (Monopile supported & Jacket on piles and caissons)
3. Prediction of deformation of the foundations
About the Lecturers
Subhamoy Bhattacharya currently holds the Chair in Geomechanics at the University of Surrey where he leads the Geomechanics Research Group and is the Director of SAGE (Surrey Advanced Geotechnical Engineering) laboratory. He is also the Programme Director for the MSc course in "Advanced Ground Engineering/Advanced Geotechnical Engineering". Previously, he held the post of Senior Lecturer at the University of Bristol, Departmental Lecturer at the University of Oxford and Academic fellowship at Tokyo Institute of Technology as well as industrial positions with Fugro Limited (UK) and Jacobs. He obtained his PhD in 2003 from the University of Cambridge, investigating failure mechanisms of pile-supported structures in liquefiable soils. In his PhD thesis, he proposed a new theory on pile failure which received the 2005 T.K.Hseih award for the best paper in civil engineering dynamics from the Institution of Civil Engineers (ICE). His further work on piles includes design principles for the foundation design of new generation Floating Production Storage and Offloading platforms, built from his experience designing piles for more conventional offshore structures. This combined experience gives him a unique insight into the problems faced by industry and the methodologies for solving these problems. His current research interest are foundations for offshore wind turbines and he recently wrote two books on foundation design:
Bhattacharya (2019): Design of foundations for offshore wind turbines, Wiley
Bhattacharya, Orense and Lombardi (2018): Seismic Design of foundations: Concepts and Applications, ICE Publishing.
Domenico Lombardi is a lecturer of geotechnical engineering at the University of Manchester. He also serves as leader of the Civil Engineering teaching group and director of the geotechnical centrifuge and laboratory. Domenico’s research interests relate to the experimental modelling and computational simulation of nonlinear behaviour of engineering solids and structures, with pioneering contributions to the areas of offshore renewable and earthquake engineering.
He is author of over 30 publications focusing on different civil engineering problems, including long-term performance of offshore wind turbines and design, soil behaviour under cyclic loading and soil structure interaction under extreme loading conditions. Domenico recently co-authored a book titled "Seismic Design of Foundations: Concepts and Applications", published by the Institution of Civil Engineer publishing.
