Swivel stacks

Minimize downtime to maximize production. Trusted by the industry as the original equipment manufacturer (OEM) of reliable and flexible swivel stacks, we put safety first by combining expertise with leading-edge innovation to deliver more reliable and predictable performance.

Why OneSubsea swivel stacks?

Our swivels are engineered to ensure that all fluids, controls, and power are safely transferred from the geostationary components such as wells, flowlines, manifolds, and risers to the rotating vessel and its processing plant assuring safe fluid transfers in all environmental conditions.

Core benefits

Compact and light

Simplified and streamlined design requires minimal space and structural support.

Safe and reliable

Continuous monitoring of the swivel stack system conditions with increased uptime.

Stack-based assembly

Smaller size footprint with modular swivel stacks and sub-assemblies stacked to fit available space.

Application

OEM-designed and manufactured swivel stacks deliver increased reliability with improved performance—field-proven and system-tested by industry experts
Setting the standard for flexibility and versatility, our designs excel across all flowing media
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
Improved uptime with smart, continuous monitoring designed with green-light philosophy to confirm availability from start-up and throughout all operational phases
