Swivel stacks

OneSubsea’s light, compact, high-pressure swivel stack systems sit at the heart of a turret, mooring and fluid transfer set-up. We put reliability, safety, and flexibility first to secure maximum uptime.

Why OneSubsea swivel stacks?
Our swivels ensure that all fluids (liquid and gas), controls, and power are transferred safely from the geostationary components (wells, flowlines, manifolds, and risers) to the rotating vessel and its processing plant under all environmental conditions.
Core benefits

Application

  • Increased reliability through proven design, quality of personnel, manufacturing capabilities, and complete system testing
  • Flexibility and versatility as standard, with each swivel design independent of the flowing medium
  • Transfer fluids safely to the rotating vessel and process plant under any field conditions

Features

  • Dynamic seals prevent flow from leaking out of the ring volume to other parts of the environment
  • High-pressure capability up to 7,500 psi
  • Green-light philosophy confirming system availability before startup and during all phases of the operation
