Current Projects
Building on the UN’s Sustainable Development Goals, energy extraction using floating offshore wind turbines (FOWTs) can become an important part of
the transition to sustainable and renewable energy sources.
A software application is developed to be able to automate a method for determining the meteorological and oceanographic conditions used as a design
basis for establishing characteristic load effects and capacity checks during FOWT design.
Kinematics and kinetics are fundamental in fluid-structure interaction and design for optimizing FOWT performance, as well as loadings for mooring,
or station keeping, and structural analysis, where both load response and structural integrity need to be evaluated.
As the generic offshore conditions are limited to turbulence and extremes, they cannot replace the site-specific calculations for the final design.
The determination of site-specific design conditions relies on a combination of different methods.
In order to establish operational parameters and limit weather criteria, a software application is developed to be able to automate a methodology for
establishing characteristic load effect and capacity check while performing installation design as part of the modelling and analysis scope of marine
operation. The application can be used as a post-processing tool along with a non-linear time domain analysis solver.
The meteorological and oceanographic data analysis involves manipulating, transforming, and visualizing data based on data analysis results using
descriptive and inferential statistics.
