Suggestions for revision or reasons for rejection

Minor Comments on the Revised version of the manuscript (version4):

Page 3 – Line 69: “exploratory study”
-> I suggest to remove the word “exploratory”.

Page 3 – Line 77 (also in the comment) : Observations with a wind speed tendency δu/δt ≥ 15 ms−1
-> The unit is m/s² not m/s

Page 5 – Setting z2 to be the … z1 to be the
-> That sounds linguistically strange to me (not a native speaker). How about: In our study z2 is the hub height of 100m.a.s.l and z1 is the height of the wind sensors and alpha is 0.12. This way we obtain the….

Page 8 – Line 150 … fall between 4 < u <= 25…
-> Unit is missing here. The same is true one line below.

Page 12 – Line 237: to exceed approx. 600km
-> Space between number and unit.

Page 15 – of at least 25%
-> Add space between number and unit

Page 20 – Line 359 … on the background flow (ref)
-> The reference is missing here.

Page 27 – Line 484-86: This research paper with he working title….
-> This is a very long sentence, please consider rewriting by e.g. removing the title of the manuscript. Also the “you reduce” sounds very colloquial to me. However, I am not a native speaker.

Figure 6: demonstrate how IQR and RCoV change…
-> I suggest to spell out IQR and RCoV out here once again as this helps reading the figure independently of the paper.

Figure 8: pair-vise
-> I guess you mean: pairwise

Figure 10: Please add a space between number and unit in the figure title.

Figure 11 & 12: The figure panels are quite small and a lot of space is wasted due to large white margins. That should be improved in the final manuscript.

Tables 4 & 5: The captions are overlapping with the table content. In general the table captions should be above the table.

Short summary

The potential of collective offshore wind power is quantified using 16 years of hourly wind speed observations. Wind power intermittency is reduced through a hypothetical electricity grid connecting five sites at the Norwegian continental shelf. We identify large-scale atmospheric situations resulting in long-term periods of power shutdown. Wind power variability and risk measures decrease in an interconnected wind power system.
