Swivel & Marine Systems
Swivel stack and fluid transfer systems for multiple applications
OneSubsea is a major supplier of swivel stack and fluid transfer systems to FPSO and FSO facilities, having delivered the first system over 20 years ago. Featuring compact designs and innovative technology, our systems are field-proven and cost-effective.
Transporting, controlling, and monitoring both liquid and gas, our fluid transfer systems provide you with compact and highly integrated solutions.
We offer
- designs for high-pressure pump system applications
- designs for internal and external turret system applications
- a fluid transfer system design that simplifies complex manifold systems in the turret area
- a reduced-size design that frees up space for other use or allows a smaller turret.
Our swivels are available to any turret supplier and can be easily integrated with both existing and new floating production systems.
Safe offshore LNG transfer
We also offer the OCT system, a safe offshore transfer of LNG in all weather conditions, comprising
- LNG loading (including bow and tandem)
- LNG transfer (including ship-to-ship)
- cryogenic piping engineering and systems.
In addition, we provide smart and compact valve assemblies, innovative pigging arrangements, trolley systems, and swivels for dynamically positioned (DP) vessels. Swivel stack systems are available for any FPSO type or size, combining high throughput with high-pressure swivel designs.
Versatile systems requiring minimal space and structural support.
A robust system, based on years of experience and designed for extreme operating conditions.
Safe transfer of LNG between two floating vessels.
A subsea loading system for deep- to shallow-water applications.
A reliable system that interfaces easily with host facilities and can be monitored remotely.
