Lecturer: experts in the field
Basics of tensor algebra. Good knowledge in fluid- and solid-mechanics.
- gives the necessary knowledge to understand the physical phenomena that occur when an offshore structure interacts with currents, waves and wind,
- provides an exhaustive overview of the actual issues and techniques in the marine renewable energies industry,
- presents some numerical tools to solve basic design problems in fluid-structure interaction.
Course main content
The course is divided in three main parts:
1. General lectures introducing basic concepts of fluid-structure interaction (2 slots);
2. Focused lectures dedicated to wind offshore and floating structures technologies (3 slots);
3. Numerical project based on the NREL FAST software to design a complete floating wind
turbine (4 slots).
This course is aimed at:
• Giving the necessary knowledge to understand the physical phenomena that occur when an offshore
structure interacts with currents, waves and wind.
• Providing an exhaustive overview of the actual issues and techniques in the marine renewable
• Presenting some numerical tools to solve basic design problems in fluid-structure interaction.
Course main content
This course would be divided into three parts.
I. In the first part (2 sessions), a review of the basics of fluid-structure interactions is presented. The
main physical phenomena that arise in all offshore industries will be theoretically addressed:
- Added mass, damping and rigidities that affect the dynamics of structures in still or flowing
- Flow-induced vibrations, such as vortex-induced vibrations, coupled mode flutter, drag and lift
II. In the second part (3 sessions), the different technologies will be presented by industrials:
- Interactions between floating structures and waves (C. Gourthier).
- Wind offshore technologies and marine thermal energy technologies (V. De Laleu).
- Wind floating technologies (C. Peyrard).
III. The last part will be devoted to a numerical project (4 sessions).
