During the MSc specialisation in Offshore Energy Systems (OES), you will study technologies related to all different kinds of energy systems such as offshore wind turbines and oil and gas production, wave energy, etc.
This programme provides you with knowledge of how to design, analyse and model mechanical systems, fluid power systems and electrical systems with complex dynamics and elements with non-linear behaviour.
Companies take an active part in providing project proposals for the problem-oriented project work, guest lectures and visits to the companies.
You will learn
- how to analyse and design subsystems for offshore wind turbines
- how to model complex offshore energy systems
- how to develop advanced control algorithms for offshore energy systems
You are educated in an innovative, dynamic and challenging environment, through a combination of research-based courses, team-based project work, and a high degree of interaction with industrial partners and energy supply companies.
The companies take an active part in providing project proposals for the problem-oriented project work, guest lectures and visits to the companies.
In each semester (except for the last) you will spend half of your study time on courses and course work while the other half of your time will be spent doing a semester project. Each semester has an overall theme, and within this theme you conduct a semester project with your project group where you investigate and attempt to solve a relevant issue within your field of study.
The study programmes at AAU are based on problem based learning and project work, which gives you a unique opportunity to acquire new knowledge and competences at a high academic level in an independent manner. You get to apply theory to practice in your semester projects, which will prepare you for your future career.
At the Department of Energy Technology, you will find a lot of well-equipped and modern test laboratories enabling you to carry out exciting laboratory experiments. These tests will verify the theoretical analysis, which you apply during the project work.
The laboratories with advanced computer based measurement and control facilities make it possible to perform realistic tests in the electrical and mechanical wind turbine area and in the oil and gas production area with possibilities for e.g. doing system stability analysis and efficiency tests.
Read more about the laboratory facilities.
For students with a Bachelor of Science (BSc) degree from Aalborg University, the credit of the project work is 15 ECTS, whereas it is 10 ECTS (INTRO project) for students with a BSc degree from another university.
The projects' technical topics are identical, but students from another university have one extra small course, about Problem Based Learning (PBL), which is the primary teaching method used at Aalborg University. Furthermore, students with a BSc degree from another university also have a course in Control theory and Matlab.
The documentation of the project work is also different:
Students with a BSc degree from Aalborg University should:
- Document the project work with a paper, a poster, a presentation at an internal conference (CES) and an appendix report, all in English.
Students with a BSc degree from another university should:
- Document the work with a project report written in English.

1ST SEMESTER PROJECT FOR STUDENTS WITH A BSC DEGREE FROM AALBORG UNIVERSITY
In the first semester, the focus of the project is on a mechanical, electrical, process system, etc. used in the offshore energy area. You and your project group analyse the set up system, and you make models using system identification and then simulates the process system. The models are then verified by experimental tests in the laboratory.
1ST SEMESTER INTRO PROJECT FOR STUDENTS WITH A BSC DEGREE FORM ANOTHER UNIVERSITY
In this semester, you will learn about the Problem Based Learning (PBL) method applied at Aalborg University by doing project work and writing a project report about a mechanical, electrical, process system, etc. used in the offshore energy area.
You and your project group analyse the set up system, and you make models using system identification and then simulates the process system. The models are then verified by experimental tests in the laboratory
- System Identification and Diagnosis (5 ECTS)
- Fluid and Water Wave Dynamics (5 ECTS)
- Probability Theory, Stochastic Processes and Applied Statistics (5 ECTS)
- For students with a BSc degree from another university: Control Theory and MATLAB (5 ECTS)
- Modelling and Identification of Offshore Systems (15 ECTS)
For students with a BSc degree from another university: Problem Based Project Organised Learning in Modelling and Identification of Offshore Systems (10 ECTS)
examples of pROJEcT topics
- Design of hydraulic system for offshore installations
- Mechanical analysis of an offshore wind turbine
- Control of a small hydraulic crane
- Design of controllers for hydraulic servo robot or an under water robot.
In the second semester, you will learn how to design, analyse, model and control offshore energy systems and relationship between the used components, including fluid power components, electrical machines as well as compressors, pumps, etc.
You and your project group write about an offshore energy system which includes fluid power, electrical and/or thermal components that you will model, analyse and control. This could be a wave energy system, offshore wind turbines, an offshore oil production process etc.
You analyse the systems and develop a mathematical simulation model. Based on the model, the energy harvesting method is analysed with regard to efficiency, technology choices and technology interaction. The analysis is the basis for setting up a control system and making a design/redesign of the system or selected parts hereof. The design may take its basis in the existing system (optimised redesign) or may include new solutions/designs and control methods. In both cases, emphasis is placed on the fact that the system is optimised with regard to energy harvesting potential (efficiency) and system performance.
The developed design and control method, or the essential parts hereof, may be experimentally verified, either in model scale or on the real system, if possible.

During the third semester, you have different options to earn the required 30 ECTS:
- You can do a traineeship in Denmark or abroad, where you take part in the day-to-day operations in the business. During the traineeship, you will write a project about one or more of your tasks during the process
- You can study a semester at another educational institution abroad or in Denmark
- You can do a regular semester at AAU with elective courses and project work
- You can begin your Master’s thesis, so your work is spread out over both your 3rd and 4th semester.
Aalborg University has collaboration agreements with universities around the world, and the programme’s research environment has a wide range of traineeship contacts.

REGULAR SEMESTER AT AAU
If you choose to stay at AAU, you will choose elective courses that give you 10 ECTS and you will work on a project about advanced control, optimisation or diagnostic/surveillance systems for offshore energy systems. Based on a model, the advanced control, diagnostic or surveillance system is set up to improve the performance of the system, either with regard to power output, energy efficiency, life time extraction, fault detections, etc. You implement and verify the system experimentally.
To practice scientific communication skills, the project’s result, or parts of it, must be published in an article written in English. This article is presented at an internal seminar.
