Abstract: As water depths for oil and gas exploration and extraction increase, structures such as flexible risers, mooring lines, and umbilical cables are increasingly being used for subsea environments. Compared to conventional fixed-type structures and vertical risers, the dynamics of flexible risers is significantly more complex. In particular, the flexible structures may be prone to dynamic instabilities. The goal of the present paper is to provide a comprehensive study of the dynamics, stability, and vibration of f… Show more

“…Our results are in agreement with our earlier work (Kim and O'Reilly (2019a)). In that paper, we showed that a catenary-type flexible riser with a non-zero horizontal offset remains stable (even when the effects of fluid transport are considered) provided the static configuration is the shorter of the two configurations having the same value of top tension (T T op ) and the prescribed top tension is above the critical top tension.…”

“…In particular, stability criteria for the catenary-type riser and the destabilizing effects of fluid flow are now more fully understood (cf. Kim and O'Reilly (2019a)). One aspect that has not been reported previously is the stabilization of a vertical riser, such as the configuration labelled v shown in Figure 1(b), when a sufficient large horizontal offset is introduced.…”
