Reviewer 3 Report
The LNG cargo containment system in the membrane-type LNG cargo tanks requires sufficient dynamic strength for the sloshing design impact load, and it is complicated and time consuming to perform direct dynamic nonlinear transient finite element assessments (DIR) against design sloshing impact loads with different design specifications. This paper is an interesting attempt and will be helpful for the design of LNG vessels.Author Response

Reviewer 4 Report
The paper developed simplified triangular impulse response function for ultimate strength of LNG cargo containment systems under sloshing impact loads. The research has practical application value of LNG carrier design and assessment. The paper is well written and can be published after minor corrections.
1. In the introduction more references regarding the use of TIRF in strength evaluation of LNG CCS can be provided. Also mention the novelty of the present study compared with the existing work.
2. In Section 4 figure 6 only a small part of CCS is modeled and mounted on the hull structure. Can this model well represent the whole CCS structure and reliable enough for validation purpose?
3. The minus sign (e.g. in Table 11) should be ‘−’, not the hyphen ‘-’.

Round 2
Reviewer 1 Report
The Authors successfully addressed most of my questions and remarks in terms of content. The quality of English and quality of figures are much better now. I also agree with issues raised by other reviewers and hope to see them fully covered.
