Top Tension Riser Fatigue Monitoring System

Volume 4: Pipeline and Riser Technology, 2011
ATP Oil and Gas Corporation (ATP) is utilizing the MinDOC 3 vessel design for their Mirage, Morgus and Telemark fields. The modeling techniques utilized during the design and verification stages of the project suggest that the production top tension risers (TTR) may be affected by a phenomenon known as Wake Induced Oscillation (WIO).

Time Domain VIV Prediction for Top Tensioned Risers

29th International Conference on Ocean, Offshore and Arctic Engineering: Volume 6, 2010
Top Tensioned Risers (TTRs) have been widely used with floating production systems such as Spars and TLPs in deepwater field developments. A TTR system provides direct access to subsea wells from a floating platform for drilling, workover, and completion operations.

Investigation of VIV Fatigue Prediction for a Top Tensioned Riser

Volume 5: Polar and Arctic Sciences and Technology; CFD and VIV, 2009
Top tensioned risers (TTRs) have been widely used with floating production systems such as Spars and TLPs in deepwater field developments. A TTR system provides direct access to subsea wellheads from a floating platform for drilling, workover, and completion operations.

Critical Aspects to the Design and Installation of Top Tensioned Risers

Volume 3: Pipeline and Riser Technology; CFD and VIV, 2007
Dual and single casing top tensioned risers are widely used by operators for deepwater floating production facility developments. These riser types provide direct vertical access for completions and workover. These single and dual barrier risers are a stable riser concept utilizing the effective tension distribution between casings and tubing to ...

Malikai Tension Leg Platform - Drilling Tender Vessel - Top Tension Riser Operations

Offshore Technology Conference, 2018
Abstract Malikai Project made a cost-driven decision to adopt the 2-body TLP-DTV configuration to Drill and Complete the Wells offshore. By opting for a Tender Assisted Drilling approach to drill and complete the Well instead of fabricating a permanent rig package, the project could save capital expenditure by building a comparatively ...

Application of Composites to Deepwater Top Tensioned Riser Systems

21st International Conference on Offshore Mechanics and Arctic Engineering, Volume 3, 2002
As offshore exploration and production activities head to deeper water, extensive efforts have been focused on mitigating the potential challenges associated with deep- and ultra deep-water riser systems. Such challenges include overcoming the hydrostatic stresses associated with the increased length of water column as well as the increase in overall ...

Effects of Slip-Stick on Top Tensioned Riser Fatigue

21st International Conference on Offshore Mechanics and Arctic Engineering, Volume 1, 2002
In a Truss Spar system, top tensioned risers are tensioned, and centralized, inside a buoyancy can stem that extends all the way to the keel. This stem and buoyancy can contact the hull by guides at the buoyancy can, at the deck stopper, at the heave plates and at the keel where the riser exits the hull and descends to the seafloor wellhead.

Top Tensioned Riser Interface With Dry-Tree Semisubmersible

Volume 6B: Pipeline and Riser Technology, 2014
Dry Tree Semisubmersibles (DTS), with the capability of supporting surface wellheads and allowing drilling and completion through direct vertical access risers, have attracted intense interest from the oil and gas industry. A wet tree deep draft semisubmersible has been carefully reconfigured considering the balance between the overall floater ...

Wave Effects on Vortex-Induced Vibrations of a Top-Tensioned Riser

Journal of Offshore Mechanics and Arctic Engineering, 2023
Abstract Offshore drilling risers and many production risers are top-tensioned risers (TTRs), connecting the vessel and seabed via joints. External loads such as currents, waves, and vessel motions introduce cyclic loads and motions on riser sections and associated components, such as universal joint, flex joints, and well head at the ...
