6 FAQs about [Floating wind turbine blades]

What is helical type floating wind turbine?

Dynamic responses of the helical type floating VAWT are compared with numerical results of the floating HAWT. The helical type floating wind turbine can be a promising choice to harvest offshore wind energy because it has the merits of straight blade floating VAWTs and could reduce the aerodynamic torque fluctuations.

Are floating wind turbines safe?

Recent years have seen an important evolution toward large-scale and increased gross capability in the design of floating wind turbines. For an up-to-date 15 MW wind turbine, the slender blades sustain undesirable risks of failure and fatigue due to the significant interaction between fluid and structure (FSI).

What are floating offshore wind turbines?

Floating offshore wind turbines can be categorized into two types in terms of the orientation of the rotational axis: floating horizontal axis wind turbines (HAWTs) and floating vertical axis wind turbines (VAWTs).

Are floating wind turbines dynamic?

Besides, Deng et al., 2022a, Deng et al., 2022b studied the dynamic responses of the helical type floating wind turbine based on an in-house numerical code. Wave basin model tests play a significant role in the technology research on floating wind turbines. A floating wind turbine suffers from complicated loads under harsh offshore environments.

Do wind turbine blades affect fatigue life and wake flow characteristics?

The deflection and vibration of the turbine blade can interfere with the fatigue life and wake flow characteristics (Yu et al., 2020 ). Especially for the floating offshore wind turbine (FOWT), its dynamic behaviours are particularly challenging in the diverse and variable marine environment.
