Reduce capex and opex

The clamp connection system’s ease of installation reduces the total cost of ownership. Suitable for multiple pipe sizes ranging from 4- to 32-in nominal pipe size (NPS), the OCS-H horizontal clamp connection system features

  • compact design and reduced hub-to-hub distance to reduce weight and cost of structures
  • minimal tie-in tooling, requiring only an ROV-operated torque tool and a stroking tool
  • ROV fly-to-place tooling that enables the use of smaller vessels for intervention operations and eliminates the use of downline
  • proprietary dual-metal gasket (DMG) to provide a metal-to-metal secondary barrier delivering reliable sealing technology
  • wet-parking capability of jumper for host structure retrieval
  • modular design for independent retrievability of components that can be reused across multiple connections
  • backseat-testing capability.

Accelerate installation time 

The OCS-H horizontal clamp connection system is smaller and lighter than conventional systems, making it faster to install with minimal operational sequences. The clamp connection system has a high structural capacity capable of accommodating a wide range of applications and has undergone an extensive qualification and verification testing program.

Configurations are available for monobore, multibore, rigid, flexible, and umbilical termination applications.
