Maximum Movement of the Drilling Riser

IADC/SPE Drilling Conference, 1990
ABSTRACT When disconnected, the drilling riser (even without buoancy modules) can collide with different parts of & moonpool and the floating rig itself. The collision may result in severe damage of the telescopic joint, and extra bending stresses.

Mechanical analysis of drilling riser based on pipe-in-pipe model [PDF]

Applied Ocean Research, 2021
Due to the presence of a drill string inside drilling risers, the mechanical analysis becomes somewhat challenging which has attracted attention from design engineers and drilling operators.

Pressured Drilling Riser Design For Ultra-Deepwater

Proceedings of IADC/SPE Drilling Conference, 2002
Abstract This paper focuses on the design considerations of a pressured drilling riser that can be used with a surface BOP in deepwater. One key element to the development and reliable use of surface BOP drilling is this (riser) link between the seabed and the drilling rig.

Design Consideration for Composite Drilling Riser

Offshore Technology Conference, 1999
Abstract High pressure drilling risers represent the most challenging application for composite materials in the offshore industry. Therefore, their successful field qualification should serve to eliminate the emotional barriers and pave the way for the broad usage of composites in similar but less demanding ...

Drilling Riser VIV – Fact or Fiction?

IADC/SPE Drilling Conference and Exhibition, 2010
Abstract Vortex induced vibration (VIV) of deepwater drilling risers due to steady current flow does occur. This has been demonstrated by BP, who have collected a large amount of drilling riser field measurements over the last 10 years [3].

Riser Modeling Scheme for a Load-Sharing Marine Drilling Riser

Volume 3: Pipeline and Riser Technology; CFD and VIV, 2007
Typical riser analysis for a marine drilling riser using the conventional composite modeling scheme will have only one line of elements mathematically representing riser pipe and auxiliary lines. The mass and weight of the riser system may be properly modeled. It is up to the analyst to include auxiliary lines’ stiffness, bending and/or axial. The rule

Titanium Drilling Risers—Application and Qualification

Journal of Offshore Mechanics and Arctic Engineering, 1999
Abstract Titanium alloy Ti-6AI-4V ELI is selected for a high-pressure drilling riser application due to its high specific strength, corrosion resistance, and favorable elastic properties. The qualification of this titanium alloy requires assessing its resistance to hydrogen embrittlement and stress corrosion cracking due to seawater with/

Advancements in Deepwater Drilling Riser Modelling

Volume 6B: Pipeline and Riser Technology, 2014
Experience with modern ultra-deepwater capable drilling vessels and their associated marine riser tensioner systems has led to increased concerns over tensioner load variations in extreme environments. Modern drilling riser tensioners are complex hydro-pneumatic systems whereby the tension applied at the slip-ring can vary significantly with tensioner ...

Study on the Effects of Drilling Riser Attachments

Volume 5: Pipelines, Risers, and Subsea Systems, 2018
A drilling riser is a conduit that provides a temporary extension of a subsea oil well to a surface drilling facility. The drilling risers are used with subsea BOP and generally used by floating drilling vessels. When used at deeper depths, the drilling riser must be tensioned to maintain stability.

A Fast Coupling for a Deepwater Drilling Riser

SPE Annual Technical Conference and Exhibition, 1984
ABSTRACT ELF AQUITAINE and TOTAL have operated the D.P. drill ship Discoverer Seven Seas in the Mediterranean Sea, temporarily establishing a new world water depth record on GLP1 well located south of Marseilles in 5 624 ft of water. The success of this well and the following well GLP2 in the same area can be partially ...
