Sažetak
Simultaneous measurements of waves and ship heave response in various headings were performed previously in a full-scale measurement campaign with a research vessel in the Adriatic Sea. Spectral moments were measured and calculated and some discrepancies were found. The aim of the present study is to calculate the exact heave response spectra for three various headings, including following seas for which the procedure is cumbersome and often avoided. Remapping of measured wave spectrum from absolute to encounter frequencies is shown, as well as the remapping of RAOs when calculating the response spectra. Differences between the calculated and measured response spectra are modelled using Artificial Neural Network (ANN) to test if they can serve as a suitable tool either to correct the error or to model the response spectrum solely based on the input wave spectrum. The overall aim is to contribute to reduction of uncertainties in seakeeping calculations.
