Course content

This course provides insight into both the physics and modeling methods used in integrated analysis of offshore wind turbines: aerodynamic loads (by BEM theory), hydrodynamic loads, control engineering for wind turbines, and solution of the dynamic equilibrium equation. It will be shown how a wind turbine is designed and dimensioned using simulation tools, and a number of technological solutions will be presented.

Learning methods and activities

A physical gathering lasting two days in Trondheim as well as digital lectures that present theory and give examples of dynamic analysis and the design process. Calculation tasks with solution proposals that also contain elements of programming.

Specific conditions

Recommended previous knowledge

Basic knowledge of structural mechanics and dynamics. The topics TKT4116, TKT4201 or TMR4182 provides a good starting point. Basic skills in the use of numerical simulation tools and the finite element method (e.g. in ANSYS or ABAQUS).

Required previous knowledge

The student must have completed the course HAV6000 before starting.

Bachelor's/ Master's degree in technology or social sciences.
