    The table presenting the individual wave height distribution for BWFZ sites II, III and IV seems to be inconsistent in terms of a) the total amount of waves and b) the wave steepness of certain presented conditions. Is this correct?

         Metocean study for BWFZ Individual H Distribution Tables Site II   Metocean study for BWFZ Individual H Distribution Tables Site III Metocean study for BWFZ Individual H Distribution Tables Site IV    The numbers in this table (‘under the tab ‘Individual_H_distribution’ at the ‘tables’ files ) for the three aforementioned sites will have to be divided by a factor 10,000. We have attached to this Q&A the corrected tables of each site separately.

        The total sum of waves per site should then be as following:

        Site I      9,319,060 (Metocean study for the Borssele Wind Farm Zone Individual H Distribution Tables Site I.xls)

        Site II     9,370,395 (Metocean study for the Borssele Wind Farm Zone Individual H Distribution Tables Site II.xls)

        Site III    9,313,575 (Metocean study for the Borssele Wind Farm Zone Individual H Distribution Tables Site III.xls)

        Site IV    9,307,749 (Metocean study for the Borssele Wind Farm Zone Individual H Distribution Tables Site IV.xls)

         

        These are yearly averaged values. Multiplying the amount of waves with the determined averaged Tm0,2 of ~3.4s results in ~1 year.

        Additionally, a limited amount of waves are very - or even unrealistically - steep. It is suggested to set to zero the joint occurrences values in the tables when the wave steepness is above what is generally considered realistic: ~0.142.
