Course Description · Offshore Wind Energy

Keywords: waves, floating structures, substructures, wave loadings.

Course Responsible: Henrik Bredmose

General Course objectives

The focus of the course is to introduce you to offshore wind energy and the engineering methods specific to this field of wind energy.


Learning Objectives

A student who has met the objectives of the course will be able to:

  • Describe the main elements of offshore wind turbine systems and the differences to land based turbines
  • Summarize the content of the offshore turbine design standard IEC 61400-3
  • Calculate a force time series from linear irregular waves
  • Derive simplistic rotor load time series from wind turbine parameters and understand the concept of aerodynamic damping
  • Analyse the production in rows of wind turbines with application of closed-form wake models
  • Apply the elements of a design basis and use statistical methods to determine e.g. a 50-year sea state
  • Describe the typical foundation types for bottom-fixed offshore wind turbines and decide on foundation types (floating, jacket, monopile)
  • Explain the basic dynamics of bottom fixed offshore wind turbines and the method for fatigue calculations
  • Apply simplified models for conceptual design of a substructure
  • Write up the equations of motion for typical floating wind turbine configurations. Determine natural frequencies and understand the dynamic interaction with the controller
  • Comprehend the economics of levelized cost of energy
  • Understand and suggest simple strategies for operation and maintenance



In this course, you will look at offshore wind turbines, wind turbine systems and offshore design codes (IEC 61400-3). You will make the calculation of wave loads in linear regular and irregular waves by the Morison equation. The course will provide you with knowledge in engineering methods for rotor loads and wake effects, offshore environmental conditions - Design basis and substructure types (monopile, jacket, gravity based) and their relative strengths. You will look into the design of substructures, floating wind turbines (technology, modelling, design), a cost of offshore wind energy and logistics, operation and maintenance.
