Swivel and marine systems

OneSubsea engineers, produces, and delivers swivel stacks and fluid transfer systems featuring compact designs and innovative technology, providing our customers with compact and highly integrated solutions.

Why OneSubsea swivel and marine systems?
The swivel stack is at the heart of the turret mooring and fluid transfer system (FTS). The swivels ensure that all fluids, controls, and power are transferred safely from geostationary parts (such as wells, flowlines, manifolds, and risers) to the rotating vessel and its processing plant.

We have accumulated more than 4.3 million operational hours and 25 years of field experience with 99.7% uptime for our swivel and marine systems. This track record has given us the confidence to say our designs can endure even the most challenging offshore environments.

Core benefits
OneSubsea is a total system supplier, with the skills and expertise to provide engineering and delivery of complete swivel and marine systems.

Application

  • Increased reliability through proven design, quality of personnel, manufacturing capabilities, and complete system testing
  • Flexibility and versatility as standard, with each swivel ring 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
  • Green-light philosophy confirming system availability before startup and during all phases of the operation
