Matlab skills: You must be able to create and execute scripts and functions; apply Matlabs built-in functions for numerical solution of nonlinear equations and ordinary differential equations; work with vectors, matrices and plotting. This level of Matlab skills is essential to carry out the course reports. Fluid Mechanics: We recommend that you are familiar with velocity fields; potential flow theory and the Bernoulli equation. Numerical Analysis: You must be able to perform numerical integration and numerical solutions to ordinary differential equations. Structural mechanics: We recommend that you are familiar with Euler beam theory; stress, strain computations for beam bending and the dynamic beam equation.

Overordnede kursusmål
Introduce the participant to offshore wind energy and the engineering methods specific to this field of wind energy.
Læringsmål
En studerende, der fuldt ud har opfyldt kursets mål, vil kunne:
  • 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.
  • 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. Write up simplified equations of motion for a floating wind turbine configuration and determine the natural frequencies.
  • Comprehend the economics of levelized cost of energy.
