We design, manufacture and deliver unique FPSO swivels to meet the demanding requirements of offshore operators worldwide. Typically comprised of electrical slip rings, hydraulic utility swivels and fiber optic rotary joints, swivels are used in a variety of Floating Production, Storage and Off loading (FPSO) Systems including buoys, turret moorings and offshore loading towers. Our FPSO swivels permit the continuous delivery of electrical power and signals, hydraulic fluids, and fiber optic signals, with unlimited freedom of the vessel to weathervane about its mooring point. All FPSO swivels are approved by a marine authority and are certified for use in hazardous locations.

Fiber Optic Rotary Joints (FORJ)
|
Part No. |
|
|
The FO190 is a multipass fiber optic rotary joint (FORJ) for 2 to 21 multimode fibers. It is passive and bidirectional and allows the transfer of data, video and other signals on separate fibers across rotational interfaces. The FO190 can be combined with our electrical and / or fluid slip rings, giving a single, compact package for optical signals, electrical power and fluid transfer.
Other options include fluid-filling for pressure compensation permitting operation at any ocean depth, and the combination of the FO242 to include up to 6 singlemode passes.
|
|
The FO197 is a single-pass, multimode fiber optic rotary joint (FORJ). It is passive and bidirectional, and allows the transfer of any type of optical signal across rotational interfaces. The FO197 fiber optic rotary joint can be combined with our electrical and / or fluid slip rings, providing a single, compact package for optical signals, electrical power and fluid transfer.
The FO197 can be assembled with pigtail lengths tailored to the customer’s application or installed with connector bushings (ST or FC). Housing, mounting flange and drive features can also be customized to meet the customer’s requirements.
|
|
The FO206 is a single-pass, singlemode fiber optic rotary joint (FORJ). It is passive and bidirectional, and allows the transfer of optical signals across rotational interfaces. The FORJ maintains the full benefit of fiber optics end-to-end in digital and analog transmission to and from rotating equipment. These benefits include high bandwidth and immunity to most forms of EMI.
The FO206 can be combined with our electrical and fluid slip rings, providing a single, compact package for optical signals, electrical power and fluid transfer. Most of the external features on the FO206 can be modified to meet the customer’s custom requirements. |
|
|
The FO215 / 292 is an ultra-compact, two pass, multimode fiber optic rotary joint (FORJ). It is passive and bidirectional, and allows the transfer of optical signals on two separate optical fibers across rotational interfaces. The FO215/292 can be combined with our electrical and fluid slip rings, giving a single, compact package for optical signals, electrical power and fluid transfer.
The FORJ can be assembled with pigtail lengths tailored to the customer’s application. Housing, mounting flange and drive features can also be customized to meet the customer’s requirements. |
|
The FO228 (single-pass multimode) and the FO282 (single-pass singlemode) are passive and bidirectional, and maintain the benefits of fiber optics (such as high bandwidth and EMI immunity) in systems with a rotational interface. These cost efficient FORJ models are designed for applications having moderate demands for optical performance and life. Due to their lens-less design, they can operate at any wavelength supported by the fiber used in the assembly.
Both models can be combined with our electrical and fluid slip rings, giving a single, compact package for optical signals, electrical power and fluid transfer. |
|
The FO242 / 291 is a multi-pass, singlemode fiber optic rotary joint (FORJ). It is passive and bidirectional, and allows the transfer of optical signals across a rotational interface on 2 to 6 separate singlemode optical fibers. The FO242 can be combined with our electrical and / or fluid slip rings giving a single, compact package for optical signals, electrical power and fluid transfer.
Other options include fluid-filling for pressure compensation permitting operation at any ocean depth, and the combination of the FO190 to include up to 19 multimode passes. |
|
|
The FO257 is a compact, two pass, fiber optic rotary joint (FORJ) for plastic optical fiber. Ideally suited to SERCOS applications, the FO257 can be combined with our electrical and fluid slip rings, giving a single, compact package for optical signals, electrical power and fluid transfer.
The FORJ can be assembled with pigtail lengths tailored to the customer’s application. Housing, mounting flange and drive features can also be customized to meet application requirements. |
|
|
The FO282 (single-pass singlemode) is passive and bidirectional, and maintain the benefits of fiber optics (such as high bandwidth and EMI immunity) in systems with a rotational interface. These cost efficient FORJ models are designed for applications having moderate demands for optical performance and life. Due to their lens-less design, they can operate at any wavelength supported by the fiber used in the assembly.
The model 282 can be combined with our electrical and fluid slip rings, giving a single, compact package for optical signals, electrical power and fluid transfer. |
|
|
The FO285 (single-pass singlemode) and the FO286 (single-pass multimode) are passive and bidirectional, and allow the transfer of optical signals across rotational interfaces. With a body diameter of only 9.5 mm and lengths of 26 mm and 19 mm for the FO285 and FO286 respectively, both units are ideally suited to applications where size and weight are critical issues. An extremely cost effective solution for high data rate signals, both models also offer other benefits of fiber optics, including low spark hazard and immunity to electromagnetic interference.
Both models can be combined with our electrical and fluid slip rings, and with our entire line of video and data multiplexers to provide a complete solution. |

Our FO5707 multi-channel on-axis fiber optic rotary joint is a unique part with many patented features. This compact assembly is available with 2 to 7 optical circuits, which can be singlemode, multimode or a combination of both fiber types. This assembly’s features make it an ideal solution when one fiber cannot carry all the required information. Its low insertion loss, less than 4.5 dB and good back reflection performance, less than -20 dB, makes it ideal for use in both laser and LED based optical systems. The broad optical bandwidth of the device, 800 to 1550 nm for multimode applications and 1300 to 1550 nm for singlemode applications, makes it suitable for systems using wavelength division multiplexing.
The concentric fiber design of this fiber optic rotary joint allows its physical form factor to remain the same regardless of the number of optical channels selected. |
Fluid Rotary Unions (FRU)
Moog Components Group's fluid rotary unions are currently used around the world to ensure reliable transmission of life support, process, power and control fluids. Currently, fluid rotary unions rated for pressures up to 15,000 PSI (1000 bar) are available. Seals are selected based on chemical compatibility, design pressure, design temperature, required service life and acceptable leakage rate. Leak collection can be supplied when required for environmental or personnel safety. Fluid rotary unions can be combined with our electrical slip rings and fiber optic rotary joints.
