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.
Core benefits
Long-lasting
OneSubsea wellheads are made to last the lifetime of a field. Our wellheads are suitable for exploration and production in extreme conditions and all water depths.
Globally available
Our subsea wellheads can be delivered anywhere in the world within months to bring greater efficiency and reliability to subsea operations.
Customisable design
We provide wellheads that are compatible with vertical or horizontal trees, blowout preventers, workover systems, and downhole well casings.
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
