Numerical Study of the Interaction between Level Ice and Wind Turbine Tower for Estimation of Ice Crushing Loads on Structure

Round 1

Reviewer 1 Report

Reviewer’s comments on “Numerical study of the interaction between level ice and wind turbine for estimation of ice crushing loads on structure”

The paper proposed a simulation model using the LS-DYNA code to analyse the interaction between level ice and wind turbine. The below comments are provided to authors to improve their work:

[1] Abstract is long. It can be shortened. Also delete the last sentence “Discussions and conclusions are presented” as this is not needed.

[2] one or two more keywords can be added; such as simulation.

[3] A brief introduction about ice conditions in offshore wind farms will be useful.

[4] It’s not clear why authors used LS-DYNA. Even though this is very useful package available on the market, the authors should list some others and define their pros and cons before they choose LS-DYNA.

[5] The authors review comprehensively some previous research studies investigating the interaction between ice and OWTs, however they didn’t outline the main different between their work and the existing works.

[6] It’s not clear what contribution Section 2 makes to the paper. It seems the experimental data were collected from a reference. So, the reviewer wonders if the authors did also an experiment.

[7] some figures in Section 4 can be transferred to appendix.

Round 2

Reviewer 2 Report

According to the last correction, I find the text quite good and extensively improved from the previous version.

I miss (still) the definition of the effective plastic strain. I mean, as the answer reports, it is dimensionless, but it could be clearer for a potential reader, to have its definition.

I would suggest a final reading and minor English-grammar correction of the text.

Reviewer 2

According to the last correction, I find the text quite good and extensively improved from the previous version.

Response: Authors would like to thank you very much for your precious suggestions and great effort to reviewing the manuscript.

I miss (still) the definition of the effective plastic strain. I mean, as the answer reports, it is dimensionless, but it could be clearer for a potential reader, to have its definition.

Response: Yes. Thank you for this good suggestion. The definition of the effective plastic strain was added in the revision.

I would suggest a final reading and minor English-grammar correction of the text.

Response: Yes. We have checked and corrected the English-grammar in the revision.
