Subsea wellheads

Through our standardized processes, common core components, and qualified, field - proven assemblies, OneSubsea delivers highly configurable wellhead solutions to bring greater efficiency and reliability while driving down capex.

What to consider about subsea wellheads?
Wellheads are the primary pressure barrier for a subsea well. Critical to the safe and reliable production of oil and gas, they are the anchor and suspension point and act as the seal element for casing strings in exploration or production phases of your project.
Core benefits

Application

  • Serve as the safety barrier for use with blowout preventers and subsea trees to control the flow of drilling, production or injecting fluids, such as gas and water
  • Form the support for the connection point for the passage of control lines for controlling downhole devices, such as subsurface safety valves
  • Welding procedures conforms to API Specs 6A and 17D, ASME Section IX, NACE MR0175/ISO 15156, and DNVGL - RP - C203 fatigue classes F3, D, or C1

Features

  • Unique hanger system with independent lockdown and sealing of the casing hangers
  • Suits a variety of casing sizes, connections grades and supporting equipment and tools
  • Flexible, reliable, and field - proven to enable project viability and help you meet a range of functionality requirements
