Mechanics of Heat Loss in Dry Tree Top-Tensioned Risers
Offshore Technology Conference, 2004Abstract Application of dry tree top-tensioned riser systems provides direct vertical access to reservoir via production risers and surface trees, wellbore access for artificial lift and wireline and coiled tubing. While the dry tree riser is gaining growingly attention for deepwater development, the challenge has ...

The Possible Role of Surface Tension in the Reduction of Top Ring Drag
SAE Technical Paper Series, 1993<div class="htmlview paragraph">In a small (4.5 KW) diesel engine, Laser Induced Fluorescence (LIF) has been used to produce detailed oil film thickness measurements around the top piston ring and liner near midstroke. The flow is “Newtonian” under the ring in the sense that using a high shear rate viscosity at the liner temperature is ...

Parametric instability prediction in a top-tensioned riser in irregular waves
Ocean Engineering, 2013The parametric instability of a top-tensioned riser (TTR) in irregular waves was predicted based on multi-frequency excitation. As the exploration of oil and gas moves into deeper water and the corresponding platforms encounter continuous wave loads, parametric resonance becomes an increasing challenge for TTR design.

Design Challenges of Top Tensioned Risers in Ultra Deepwater Applications
Volume 4: Pipeline and Riser Technology, 2011A Top Tensioned Riser (TTR) system provides direct access to subsea wells from a floating platform for drilling, workover, and completion operations. TTRs have been widely used with floating production systems such as Spars and TLPs in deepwater field developments. This paper investigates design challenges of TTRs in ultra deepwater applications.

Weather Window Determination of Top-Tensioned Riser Deployment With Guidewires
Volume 4B: Pipeline and Riser Technology, 2013To replace 20 of the 42 top-tensioned production risers for the Statoil Snorre A platform, the planned riser deployment will use a guidewire and guide frame system. A suitable weather window needed to be determined for the deployment to avoid clashing the deploying risers and adjacent connected risers. Such clashing could cause severe consequences such
