Abstract: We mainly study the top tensioned riser (TTR) installation analysis method. The TTR installation process has the characteristics of complicated positioning, easy interference and difficulty of stress control. In order to finish TTR installation successfully, the guideline, guide arm, key parameters of installation facility and riser positioning cases should be reasonably selected. The appropriate weather window and guide arm arrangement are determined via strength analysis, interference analysis and dynamic time domain analysis. This will provide the reference for TTR installation design and offshore operation.
