Offshore Wind Energy – Design of Substructures – course

Offshore Wind Energy - Design of Substructures

Offshore Wind Energy – Design of Substructures

Through the course, you will learn about offshore wind energy and the engineering methods used within this specific field of wind energy.

You will touch upon several different subjects relevant to engineers working with offshore wind energy and substructure.

During the course, you will be working with the following:

  • Offshore wind turbines and wind farms
  • Overview of offshore design codes like IEC 61400-3-1
  • Calculation of wave loads in linear, regular, and irregular waves by the Morison equation
  • Engineering methods for computation of rotor loads
  • Offshore environmental conditions – design basis
  • Wakes
  • Substructure types – monopile, jacket, gravity based – and their relative strengths
  • Design methods for monopiles
  • Floating wind turbines (technology, modelling etc.)
  • Soil models
  • Cost of offshore wind energy

Learning objectives

Once you have completed the course, you will be able to:

  • Describe the main elements of offshore wind turbine systems and the differences to land based turbines.
  • Be familiar with the offshore turbine design standard IEC 61400-3-1.
  • Calculate a force time series from linear irregular waves.
  • Apply simplistic rotor load time series as part of a fatigue calculation and understand the concept of aerodynamic damping.
  • Explain the basics of wake effects inside offshore wind farms.
  • 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 the elements of a design basis together with simplified models for conceptual design of a substructure.
  • Determine the natural frequency for an offshore wind turbine support structure using approximate formulas.
  • Comprehend the economics of levelized cost of energy.

Floating Wind Turbines

Henrik Bredmose tells about the possibilities and benefits floating wind turbines bring about.


Admission to the course requires a B.Sc. or B.Eng. degree or higher and at least, two years of relevant working experience.

The relevant working experience could be – but is not necessarily restricted to – employment in:

  • The wind energy industry.
  • Oil and gas companies.
  • Shipping companies.
  • Companies performing environmental assessment.
  • Public agencies with responsibilities related to engineering and natural sciences.
  • Since the programme is taught in English, you must have proficient English skills.

Recommended prerequisites
In addition to the admission requirements above, we strongly recommend that you have mathematics and programming skills equivalent to B.Sc. or B.Eng. level or higher.

Technical requirements 
You will need a PC with a stable internet connection to follow this online course.

Course platform
All master courses run on the web based course platform DTU Learn. Once you access the platform, all the courses you are signed up for, become available for you – after the semester start day.

Learning online

The course is divided in 13 modules, one per week in the semester. Each module includes a combination of video lectures, exercises, quizzes and/or reading material depending on the module. This course material is available any time to allow for flexible studying conditions.

Furthermore, you are offered weekly live Q&A sessions to get in dialogue with the course lecturer and fellow participants.


This course is concluded with an oral exam, conducted online.
