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
