“…The structural mass matrix is a diagonal matrix. Structural damping is often excluded as in References [50,66,[73][74][75], but may also be included [65,76] to improve numerical stability. For chain-link mooring lines, usually bending and torsion effects are excluded.…”

“…74 models. As was in Case 3, the tension fluctuations occurring during 760 s < t ≤ 800 s are due to the occurrence of nodal grounding.As shown in the tension histories for the SM 0.84 , SM4.74 7 and MSM 4.74 models, this type of fluctuations can be mitigated by refining the nodal density and judiciously modifying the seabed force coefficients.…”

This project received funding from Economic Development Board of Singapore and was carried out with the support of Energy Research Institute @NTU, Lloyd's Register Singapore and Lloyd's Register Applied Technology Group; the resources and assistance provided by these organizations are duly acknowledged. I would like to thank my industrial supervisor, Mr Steve Kim, for his support and encouragement, and Dr Frank Lin for his supervision and mentorship during my overseas attachment and for developing the scope of the project. I am also very thankful to Mr David Whitehouse, with whom I have had the pleasure of running the Hypothermic Half, for helping me to get settled in at Applied Technology Group and Halifax. Mr Anand Bahuguni and Mr Krishnamoorthi Sivalingam have supported me at various stages of this journey and I am grateful for their kindness and concern for me. I would also like to especially thank Dr Kie Hian Chua for giving me plenty of valuable technical advice and suggestions, Mr Tan Hoon Kiang for his steadfast encouragement, mentorship, and belief in me, and Mr Ravi Jeeva Rathinam for his understanding, support, and advice for work and life. I am also thankful for my friends and colleagues who have walked this journey with me. I am thankful for the projects that we did together, for the detours from our work that we took together, and for the memories we have made.To my family, my parents and grandmothers, my grandfather who lives on in our memories, and my closest aunts, my deepest gratitude goes to you for your love and support. To 季烨, who gave me the courage to begin this adventure and stuck with me through it all, thank you, for everything that you have given to me.
