TL;DR: An iterative noise extraction and elimination method is proposed, to solve the difficulty of modal parameter identification caused by contaminated high-energy components in measured signals, and one can conclude that the proposed method outperforms the Fourier transform due to its limitation of fixed frequency resolution.

TL;DR: These monitoring campaigns of an actual in service OWT not only provide modal information support for structural maintenance and operation safety assessment, but also provide a real data reference for wind turbine design.

TL;DR: The proposed time-domain response estimation method provides accuracy similar to that of the regression method but outperforms the curve fitting and the realization methods, obviously because of the improperly used initial values.

TL;DR: Numerical results show that the proposed time-domain response estimation method can provide much more accurate time- domains responses compared with those from the traditional time- domain methods, even when the time step used is not so accurate, but also has better computational efficiency.

TL;DR: A new estimation method, which focuses on the efficiency of utilizing wave energy by the WUSV, is proposed and is expressed in the form of the product of several non-dimensional parameters.
