Robust adaptive boundary control of a flexible marine riser with vessel dynamics
Automatica, 2011 -In this paper, boundary control of a flexible marine riser with vessel dynamics is developed to reduce the riser's vibrations. To provide an accurate and concise representation of the riser's dynamic behavior, the distributed parameter model ...

On the probabilistic distribution of loads on a marine riser [PDF]
Ocean Engineering, 2017 Marine risers are subjected to various types of loads, such as axial tension and bending moments arising from the motions of an offshore platform in association with waves, winds, and currents.

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

Nondeterministic Analysis of a Marine Riser
Offshore Technology Conference, 1973ABSTRACT This paper presents some significant results of analytical investigations of the effect of various problem parameters on the nondeterministic response of a marine riser to random wave forces and deterministic steady current forces. It is shown that the response to random wave forces is highly dependent upon

Hydrodynamic Tests on Marine Risers
Offshore Technology Conference, 1982Abstract This paper presents experimental techniques and resultant data from an ongoing programmed of large scale laboratory tests on marine risers in waves. The experiments are being carried out in the No. 3 tank of the National Maritime Institute in England which has a water depth of 25 ft (7.6 m).

Top Tension Control of a Flexible Marine Riser by Using Integral-Barrier Lyapunov Function
IEEE/ASME Transactions on Mechatronics, 2015 This paper presents a boundary controller for a flexible marine riser to suppress the riser's vibration with a top tension constraint. The flexible marine riser is described by a distributed parameter system with a partial differential equation and four ...
