OneSubsea Swivel and Marine Systems

Swivel Stack SySteMS

the swivel stack is the heart of the turret mooring and fluid transfer system (FtS). Reliability, safety and flexibility are key to securing increased uptime for the floating production, storage and offloading (FPSO) / floating storage and offloading (FSO). the swivels ensure that all fluids (liquids and gas), controls and power are transferred safely from the geostationary parts (i.e., wells, flowlines, manifolds and risers) to the rotating vessel and its process plant under any environmental conditions in the field.

OneSubsea is able to engineer, produce and deliver swivel stacks and fluid transfer systems to FPSOs and FSOs worldwide. we provide a safe and reliable production flow year after year. in addition, the OneSubsea FRieND Remote Surveillance and Diagnostic System is offered for the systems.

with the support of its parent companies, OneSubsea provides the oil industry with products that are engineered, manufactured, tested, installed and commissioned as turnkey systems and modules.
