Detailed Calculation Maximum Wave Heave Force

The maximum wave heave force can be determined from a wave heave force Response Amplitude Operator (RAO) by following the next steps:

STEP 1: From the maximum significant wave height HS a Bretschneider Wave Spectrum will be generated with the mean centroid period T1 and the mean zero-crossing wave period T2

t1 and  t2

STEP 2: For each wave frequency the outcome of Sz(w) is calculated brettschneider

(Bretschneider Wave Spectrum)

STEP 3: For each wave frequency the wave spectrum is transformed into a heave force spectrum by multiplying it with the RAO squared

step3

 

STEP 4: Finally the amplitude of the wave heave force is calculated from the area under the heave force spectrum 5
