Methodologies

Choose between four different methods to design and analyse floating offshore wind substructures based on your and the industry's needs.

Time Domain Methods

 

Time Domain Direct Load Generation

For engineers performing detailed design, this is the most accurate method available with an associated higher computational cost. It may be used to investigate which effects of non-linear hydrodynamics are relevant for the model and serve as a baseline to determine if the faster Load and Response Reconstruction methods can be used.  

 

Time Domain Load Reconstruction

A more cost-effective method than the Time Domain Direct Load Generation method, which is also applicable for detailed design stages and down to (pre)FEED stages. With its associated capabilities and assumptions, it can be used to investigate the effect of dynamics on the structural response and both fatigue and ultimate limit state results.

 

Time Domain Response Reconstruction

The most computationally efficient time domain method available in the market. This method can be used from (pre)FEED and all the way to detailed design for structures that are not dynamically sensitive.

Frequency Domain Uncoupled

The quickest method available, it offers fast and efficient design iterations suitable for initial sizing, early design and prototyping stages.

 

FOWT method comparison

One of the reasons we like using Bladed and Sesam together is because we can bring our initial foundation design closer to our final and more refined design, earlier on, meaning there's less risk.
