Round 1

Reviewer 1 Report

The paper presents propulsion units intended for distributed ship systems simulation and analysis, it will provide a prime suggestions to the other researchers for the system design and simulation. The manuscript could be improved based on the following advice:

(1) The "Area ratio" in table 1 is 0.983, which seems too large leading to very low propeller efficiency, please check it.

(2) Please describe the meshing method in CFD simulations.

(3) why not 3-D simulation results presenting in the results part.

(4) The figures pixel is not enough, please check and revise it.

Reviewer 2 Report

Broad comments. The authors have made a concise overview of the topic and a brief reference to existing literature. They have indicated the main task of the paper among its motivation. Finally, they have pointed out the key message and the potential benefits of their work.

Specific comments. In general, the text is very well structured and has clearly defined topics. Some comments for improvement:

  1. As a general drawback, I could say that there is no reference to works (e.g. [1]) that were based on data-driven evaluation of similar equipment.

[1] Themelis, N., Ch C. Spandonidis, and Ch Giordamlis. "Data acquisition and processing techniques for a novel performance monitoring system based on KPIs." Sustainable Development and Innovations in Marine Technologies. CRC Press, 2019. 306-315.

  1. Authors should better explain/justify the text within the lines 123-128.
  2. Besides authors should provide (e.g. in tabular form) of the monitored physical quantities, mentioned in line 223.
  3. The authors describe their methodology, including their parametric numerical experiments, clearer.
  4. Authors could consider adding quantitative results in addition to the qualitative figures provided in the relevant section.

Round 2

Reviewer 1 Report

I am more or less satisfied with revisions and the author revised the manuscript very careful. I think it is suitable to be published in the journal.

Reviewer 2 Report

Authors fully addressed previous comments. The work seems to be improved significantly.
