Tests at DHIĮric Nicolas Hofschulte and Alex Gandia Santaya’s results of the series of tests is going to be applied directly in the FloatStep project. It is important to constantly validate and improve the calculation models in order for them to represent the controlling physics to the extend possible,” he says. Professor and Head of Section at the Department of Wind Energy, Henrik Bredmose, confirms the importance of the topic of the students' project: “The dynamics between the floater and the wind turbine is always an interaction between the load on the rotor, the pressure from the waves and the control – in the conditions at the site. The two master students, Eric Nicolas Hofschulte and Alex Gandia Santaya conducted the tests as a part of their master project which includes numerical calculations and analysis of the measuring results, too. During this spring tests of a model took place at DHI with a scale model of a floating wind turbine.

In addition, the researchers from the project improved the engineering models for the wind turbine loads and calculation methods for the floater which later is going to be validated in full scale against the TetraSpar Demonstrator project of Stiesdal Offshore Technology that is to be installed in Norway during this summer. In the FloatStep project methods and technologies are evolved to optimize floating wind turbine foundations and tower designs and improve the current technical tools.

Life prediction of cracked components and structures using level I, II and III FADs Defect assessment using failure assessment diagrams Fatigue crack initiation and growth in offshore structuresĪ brief introduction to S-N curves, Linear Elastic Fracture Mechanics, Stress intensity factorĢ. This webinar is designed to give attendees a more rounded appreciation of the unique considerations that should be given to the structural integrity assessment of offshore wind turbine foundations. Given the harsh environment of offshore wind turbines, a major design and O&M challenge is the corrosion and fatigue of the structure.
