Two Tier Well Riser Top Tensioning System

Offshore Technology Conference, 2000
Abstract The paper presents the results from a feasibility study carried out by Kvaerner for a top tensioned riser system adapted for its deep-water Deep Draft Floater production unit, which often is referred to as a multileg SPAR.

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.

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 ...

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 ...

Top Tensioned Riser Systems for a New Floater Type

All Days, 2010
Abstract The Telemark Hub is being developed with a new design deep-draft floating production system [1]. This paper describes development of top-tensioned drilling risers and production risers with dry trees. The riser system includes standard riser joints, specialty joints and an innovative riser tensioning system.

Extreme Value Estimation of Mooring Lines Top Tension

Volume 3: Structures, Safety, and Reliability, 2019
Abstract It is known that the mooring system of floating platforms responds non-linearly to environmental loads. Even though the wave-frequency excitation can be assumed as a Gaussian process, the line tension generally is not a Gaussian process due to the second-order slow-drift floater motions and the nonlinearities of the system ...

Dry Tree Top Tensioned Riser Systems

OTC Brasil, 2013
Abstract As oil production moves further offshore and into deeper water, the technology needed to meet the increased demands evolves. New technologies and new applications of existing technologies bring new challenges and often create unintended consequences.

HRM Professional Role Tensions: Perceptions and Responses of the Top Management Team

SSRN Electronic Journal, 2013
AbstractThe aims of the research are to explore evidence of professional human resource management (HRM) role tensions, the factors that affect HRM role tension, and to consider the impact on management perceptions when role tensions exist. Using a qualitative approach, 25 interviews were conducted in Australia with senior HRM personnel, top management
