Dynamics of Flowline/Riser Systems
Definition
Pipeline and riser systems are one of the offshore production equipment that plays a vital role in the transportation of oil and natural gas from subsea wellhead to topsides of the floating units/vessels. Basically, risers are conductor pipes that connect floaters on the sea surface and the wellheads at the seabed. They experience different sources of dynamic loadings coming from wave, currents, VIV, hydrodynamics, vessel motions, and slugs which cause instabilities and vibrations of the system.
Scientific Fundamentals of Riser Structures
Riser Description and Configurations
There are mainly two kinds of risers which are rigid risers and flexible risers. A hybrid riser is the combination of these two.
Rigid Risers
Steel catenary risers (SCR) and top tensioned risers (TTR) are various forms of rigid riser systems. In practice, the top tensioned risers are deployed in shallow waters, but as design for higher water depth is accounted, a new...
