Subsea Production Manifold Systems

Key role in well testing, isolation, sampling, and allocation management

Key role in well testing, isolation, sampling, and allocation management

A production manifold is a subsea structure containing valves and pipework designed to commingle and direct produced fluids from multiple wells into one or more flowlines. Our cluster-style production manifolds play a key role in well testing, isolation, sampling, and allocation management.

Our systems are flexible in design so that they can be configured for multiple well slots for flowline connection systems. They have the ability to incorporate controls, gas lift distribution, or both.

Horizontal-vertical hybrid configurations are also available.

Horizontal flowline connections

  • Facilitated self draining, aiding in flow assurance
  • Independently retrievable manifolds and jumpers through use of an intermediate structure
  • Reduced snagging risk in shallow water
  • Integrated guidance system for horizontal connection system
  • Enhanced dropped-object protection
  • Configurable for round-trip piggability via integral or retrievable pigging loops

Vertical flowline connections

  • Compact structural design
  • Simplified jumper installation
  • Configurability for round-trip piggability via integral or retrievable pigging loops
