Dynamic Analysis of Marine Risers
Offshore South East Asia Show, 1982Abstract Drilling and production in deeper water set new requirements to the design of marine risers. In this paper the most common methods of dynamic analysis of such risers are reviewed and discussed with reference to a set of full scale data.

Vibrations of Marine Riser Systems
Journal of Energy Resources Technology, 1980A discrete multi-degree-of-freedom model is used to study the dynamic response of marine riser systems to loads generated by sea waves and currents. A linearization scheme is used to determine an approximate solution for the system response. A variety of studies regarding the effects of system and environmental parameters on the maximum bending stress ...

The Marine Riser- A Procedure for Analysis
Offshore Technology Conference, 1969Oil drilling and producing operations have been moving farther and farther offshore to exploit new gas and oil resources. Marine operations pose problems not encountered in land operations such as weather, ocean waves and currents, limited storage space, corrosion, and transportation difficulties. One method of offshore operations places
