Maximum Movement of the Drilling Riser
IADC/SPE Drilling Conference, 1990ABSTRACT 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.

Deepwater Drilling Riser System
SPE Drilling Engineering, 1986Summary The principal focus of this paper is to discuss and summarize, from the manufacturer's perspective, the primary milestones in the development of the marine riser system used to drill in record water depths off the U.S. east coast.

Pressured Drilling Riser Design For Ultra-Deepwater
Proceedings of IADC/SPE Drilling Conference, 2002Abstract 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.

Drilling Riser Integrity Assurance for Deepwater Floating Drilling
Offshore Technology Conference, 2017Abstract Objectives/Scope Historically, deepwater drilling riser challenges were always seen to be related to riser weight and metocean stresses. Consideration of the riser as a pressure vessel has been limited to production riser applications or smaller high pressure risers used for floating surface ...

Design Consideration for Composite Drilling Riser
Offshore Technology Conference, 1999Abstract 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 ...

Riser Modeling Scheme for a Load-Sharing Marine Drilling Riser
Volume 3: Pipeline and Riser Technology; CFD and VIV, 2007Typical 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

Drilling Riser VIV – Fact or Fiction?
IADC/SPE Drilling Conference and Exhibition, 2010Abstract 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].

Drilling Riser Stress Measurements
Journal of Engineering for Industry, 1971Field measurements of drilling riser stresses during drilling operations have been made. The field-measured stresses are in agreement with those predicted by EPR’s pseudodynamic riser stress analysis computer program. The agreement between computed and measured values for both time-average stress and stress variations substantiates the validity of the ...

Titanium Drilling Risers—Application and Qualification
Journal of Offshore Mechanics and Arctic Engineering, 1999Abstract 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/
