A frequency domain fatigue analysis using the Battelle structural stress methodology has been performed on a shear plate connection detail typical of a representative cell spar in North Sea service. In parallel, time domain cycle counting of the Battelle structural stress ranges has been performed on the same connection detail. The frequency and time domain fatigue damage computed at various locations is reported and compared. Recommendations regarding the application of the Battelle method to wide-banded spectral fatigue problems are provided.
