Tie-Back to TLP and SPAR

Because of the dynamic forces imparted to a subsea wellhead from a production vessel that is constantly in motion, the fatigue life of the well equipment becomes an important issue. The Dril-Quip Tie-Back for Floating Production and TLP Systems incorporates some key equipment components:

  • DX® and DXe® Wellhead Connectors for high preloaded production riser connection
  • Easy stab and make-up at high misalignment angles
  • High bending and tension load capacity
  • High pressure capacity
  • All metal-to-metal seals with resilient backup
  • Easily adapted to accommodate most casing and production riser programs
  • Computer analyzed and validation tested
  • Available with mechanical or hydraulic locking systems
  • Tie-Back Connector can be pressure-tested
  • Stab seal is field-replaceable
  • DX Wellhead Gasket can be pre-installed by ROV prior to tie-back for rig time savings
  • Dual metal-to-metal sealing profile on Tie-Back Connector gasket prep
  • Field proven performance
