Dril-Quip’s SS-15 Subsea Wellhead Systems are rated for 15,000 psi working pressure and feature a field-proven, “weight-set” metal-to-metal annulus seal. The SS-15 system features the weight-set technique to install and retrieve all of the subsea wellhead components, including nominal bore protector, wear bushings and test tools.
System Features:
• Reliable, trouble-free operation¬; fewer trips required
• Weight-set seal assemblies provide true dual metal-to-metal annulus seal
• Seal assemblies and hangers designed for 15,000 psi working pressure, H2S service
• Same seal assembly fits all hangers 13-3/8" and smaller
• Seal assemblies automatically lock to casing hangers and lock casing hangers to the wellhead
• Seal assemblies are retrieved by vertical pull¬—no rotation required
• All casing hangers are automatically centralized in the wellhead
• Large flow-by areas around casing hangers
• High-pressure and high load capacity due to a unique single landing shoulder at the bottom of the 18-3/4" wellhead housing
• High-bending load capacity between the conductor and 18-3/4" housing
• BOP stack can be tested with nominal bore protector and wear bushings installed
• Tubing hanger sealing area and lockdown profile standard
• Threaded profile standard on all casing hangers for emergency situations
• Pressure-balanced, fail-safe “in-place” annulus shut-off system available
• The lower O.D. of the 18-3/4" wellhead has a reaction ring to transfer bending loads to the conductor wellhead
• Available with a variety of supplemental casing hanger systems
ending loads to the conductor wellhead •Available with a variety of supplemental casing hanger systems
