Speed Trial - Weather Correction (ISO 15016)
Apply wind and wave corrections to measured trial speed per ISO 15016:2015 - the contract speed verification method.
Wind correction
-0.60kn
Wave correction
-0.78kn
Calm-water speed
15.58kn
Formula, assumptions, and limits
Simplified example; full ISO 15016 uses spectral analysis of waves and thrust-fraction corrections. For contract acceptance use the full procedure.
