Online Foundation Design of Offshore Wind Turbine Structures Training

Via Zoom.

ABOUT THE COURSE

The costs of offshore wind are currently, significantly higher than onshore wind. A significant contributor to this higher cost is the cost of the foundations for the turbines. Hence a rational and optimized design of foundation for wind turbines is essential to reduce the overall cost.
This course gives a detailed knowledge about the design and analysis of mono pile, and jacket structure foundations. This course also includes the soil pile interaction and the dynamic responses.
This course will provide a general overview of the aero-servo-hydro-elastic software Bladed and the different engineering models behind the code in order to represent the coupled dynamics of offshore wind systems

Who Should Attend

Engineers and researchers involved in the design of offshore wind farm foundation, Contracts engineers, Wind turbine Installation companies, Team leaders, Conversion Engineers, Project engineers and managers, offshore controls engineers, Safety inspectors will benefit from attending this course. The course is innovative in both content & structure with a careful balance of theory & practice.

CV’S OF LECTURERS:

Prof Subhamoy Bhattacharya,Chair in Geomechanics, University of Surrey

Professor Subhamoy Bhattacharya currently holds the Chair in Geomechanics at the University of Surrey where he leads the Geomechanics Research Group. He is also the Programme Director for the MSc course in “Advanced Ground Engineering/Advanced Geotechnical Engineering” and the Director of Undergraduate Studies in Civil 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 Consulting Engineering Services (India) Ltd – now Jacobs. He obtained his PhD from the University of Cambridge, investigating failure mechanisms of pile-supported structures in liquefiable soils. 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. 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. His work on p-y curves for clay appears in the latest API/ANSI/ISO code of practice. His current research interest are foundations for offshore wind turbines, seismic behaviour of piles.

Some of his publications are:

Dr Yang Yang, associate professor at the Ningbo University, China.

Dr Yang Yang obtained his PhD degree from University of Shanghai for Science & Technology (USST). His doctoral thesis is on ‘Seismic analysis of offshore wind turbines’. He is an outstanding student in his undergraduate class of USST where he did his bachelor’s degree in Power Machinery and Engineering. He was a visiting scholar at the Liverpool John Moores University (LJMU), UK where he was responsible for various projects namely (i) Development of a fully coupled tool for a multi-body floating offshore wind turbines (FOWT), (ii)Development of FOWT controller considering the platform motion feedback;(iii) Identification of damage hotspots of the FOWT and (iv) Development of a damage diagnosis approach for the FOWT. He is now an associate professor at the Ningbo University, China.

Content of the Lectures:

Lecture 1: Overview of the whole Wind Turbine structure
General overview of the overall wind turbine structure/wind farm keeping in mind the concepts necessary for foundation design.

Lecture 2: Loads on the offshore wind turbine structure
This lecture will focus on the main loads on the structure from wind, wave, 1P and 3P with the aim to obtain the mudline bending moment for foundation design. Also this lecture will describe a simple frequency domain methodology to obtain the critical loads (overturning mudline moment, lateral and vertical loads) in the foundation due to the 4 types of loads. An EXCEL example will be taken to show the methodology.

Lecture 3: Consideration for foundation design and the calculations necessary
The design consideration includes the following Limit States: ULS (Ultimate Limit State), SLS (Serviceability Limit State) and FLS (Fatigue Limit State). Issues related to installation will also be discussed. This section will also discuss the calculations that needs to be carried out the designers: (a) ultimate capacity of the foundation; (b) natural frequency of the whole system; (c) deflection and rotation of the foundation; (d) long term tilting of the foundation and change in natural frequency.

Lecture 4: Simplified hand calculation of case studies

This lecture will take an example of a wind turbine along with wind, wave and geotechnical data to carry out step by step calculations.
