Objectives and Content
The course gives an introduction to selected topics relevant for the utilization of offshore wind energy. The course gives the students basic insight about the wind over the ocean and how the wind energy can be extracted. Further, the challenges related to wind turbines in ocean waves are addressed. Key topics covered in this course are:
- History and future development of offshore wind energy.
- Basic meteorology for offshore wind, including techniques for measurement and analysis of wind fields.
- Aerodynamics of wind turbines. Momentum theory, airfoils.
- Characteristics of wind turbines and wind farms.
- Description of ocean waves. Wave spectra and wave statistics.
- Introduction to wave loads on support structures.
On completion of the course, the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:
The student has basic knowledge about
- the characteristics of the marine atmospheric boundary layer and techniques for analysing wind fields.
- aerodynamic principles for extracting wind energy
- kinematics and dynamics of ocean waves.
- the principles of computation of wave loads on simple marine structures.
The student can
- estimate vertical wind profiles in the lower atmospheric boundary layer and perform statistical analysis of wind field data
- use basic momentum theory in estimating power from wind turbines
- describe irregular ocean waves by linear wave theory
- estimate wave loads on simple marine structures.
- Understands the basic principles of the methods used for estimating power extraction from and loads on offshore wind turbines.
- can ask critical questions to assumptions made and results obtained.

Forms of Assessment
Written exam, 4 hours
Examination Support Material
Non-programmable calculator, according to the faculty regulations.
The grading scale used is A to F. Grade A is the highest passing grade in the grading scale, grade F is a fail.
Examination both spring semester and autumn semester. In semesters without teaching the examination will be arranged at the beginning of the semester.
The reading list will be available within June 1st for the autumn semester and January 1st for the spring semester
The course will be evaluated by the students in accordance with the quality assurance system at UiB and the department
Normally, referents groups will be used each year.
The Programme Committee is responsible for the content, structure and quality of the study programme and courses.
