“…Former research use straight pipe as a model. As used by Hallam [4] stated that piping system failure often occured in bending area which produce maximum stress. And field experience shown that pipe has many types of bend, tee and angle variations.…”

Internal fluid flow can affect a vibration on the dog leg subsea pipeline due to bend in the pipe structure. This study was done by varying fluid speeds which flows inside of piping system to obtain a pipe safety limitation due to internal flow. The results showed that the vibration occurred in the piping is still within safety tolerance, and distribution of maximum stress occurred at 900 bend. Therefore, it was recommended to add the buffer support installed in the middle of span to reduce amplitude at the longest segment.
