Tie-Back to Fixed Platform

Dril-Quip's SS-15 Subsea Tie-Back System represents the latest in tie-back systems technology. This subsea tieback system provides an easy, reliable means of tying back a subsea wellhead for surface completion. It incorporates an internal locking profile to optimize the operator’s ability to tie back in adverse conditions and decrease platform costs.


Features of the Subsea Tie-Back System Include:

  • High preload for high bending and tension load capacity
  • Metal-to-metal seals with resilient backup
  • High pressure capacity
  • Available with annulus monitoring when used with special annulus monitoring casing hanger
  • Stab-In Tie-Back Tools minimize rotation and provide for easy make-up
  • Easily adapted to accommodate most casing programs
  • Engineering analyzed and tested
  • Field proven

Features of the Subsea Tie-Back System Include:

  • Standardization of connector regardless of wellhead locking profile
  • Small O.D. profile (saves expense in platform costs)
  • Easy stab at high offset and misalignment angles
  • Low torque for high bending and tension load capacity
