Development Of A Nonsealing Mudline Tubing Hanger For The Medusa Truss Spar
Offshore Technology Conference, 2005Abstract Use of a mudline tubing hanger (MLTH) is common in dry-tree deepwater applications with tight tolerances for tension management. It is run integral to the tubing string and can provide a pressure barrier as well as reduce the load to the platform. In single riser applications, a sealing MLTH is necessary to

Strength design method for tubing hanger of subsea christmas tree against big temperature difference
China Ocean Engineering, 2014The tubing hanger is an important component of the subsea Christmas tree, experiencing big temperature difference which will lead to very high thermal stresses. On the basis of API 17D/ISO 13628-4 and ASME VIII-1, and by comprehensively considering the erosion of oil and the gravity load of the tubing, a calculation model is established by regarding ...

Wireless Tubing Hanger Deployment in Deepwater Environment, the Bonga Field Experience
Offshore Technology ConferenceAbstract The deployment of Tubing Hangers (TH) in offshore subsea wells is a critical aspect of oil and gas production systems. The Tubing Hanger is a key component in well completion, allowing for the suspension of tubing, communication of hydraulic and electric functions downhole, and sealing the annulus. The installation and retrieval

IADC/SPE Asia Pacific Drilling Technology Conference, 2014
Abstract Traditionally, to complete a subsea well with a vertical Christmas tree, it is necessary to land the tubing hanger and install and pressure test a wireline set tubing hanger plug. Once the plug is tested, the subsea BOP can be removed, the vertical Christmas tree can be installed, and the plug retrieved through the work-over ...
