An analysis model is formulated and described for calculating the static and dynamic behavior of a marine riser supported from a floating vessel. Static, dynamic, and combined analyses were performed on a 16-inch riser in water depths of 400 to 200 ft. to demonstrate the consequences of extrapolating an existing riser design into deeper water. The results showed that it is practical to use the riser in 2000 ft. of water if suitable buoyancy is attached to the riser. Based on the study of this specific riser, the dynamic behavior of the riser, caused primarily by vessel response to waves, proved to be a significant design factor for all water depths. Further, the most significant factor in extending riser design into deeper water is the increased tension required to support riser which may exceed the practical axial load-carrying capacity of the riser as the water depth approaches 2000 ft.
