Through standardized processes, common core components, and qualified, field-proven assemblies, OneSubsea can design a subsea manifold tailored to your field architecture and deliver it anywhere globally within 18 months.

These highly configurable solutions are designed to bring greater efficiency and reliability to subsea operations, enabling project viability and helping you meet a range of functionality requirements while driving down capex.

Flexible functionality

Manifolds can be configured to generate numerous structure types:

  • cluster manifolds with two or more well slots
  • pipeline-end manifolds and terminations
  • tie-in structures
  • riser bases and gas export systems
  • template manifolds
  • overtrawlable and fishing-friendly designs.
