Rotary Slip ringsRotary Slip RingsOur rotary products are supplied by Focal Technologies (MOOG Component Group) who has delivered trusted technology products and services to the offshore petroleum, oceanographic, seismic and maritime industries for more than 20 years. Their experience and our dedicated team of professionals specialices in providing custom electrical slip rings, fiber optic rotary joints, hydraulic utility swivels for the worldwide maritime industry. Fibre Optic Rotary Joint Model 286 The Fibre Optic Joint Model 286 is a single-pass, multimode fiber optic rotary joint. It is passive and bi-directional and allows the transfer of optical signals across rotational interfaces. With a body diameter of only 9.5 mm and a length of 19 mm, the rotary Model 286 is ideally suited to applications where size and weight are critical issues. Fibre Optic Rotary Joint Model 242 The FO242 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 Fibre Optic Rotary (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, with ISO 9000 quality. 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. Features - 2 to 6 singlemode channels - Can be combined with our electrical slips, fluid unions and the Fibre Optic Rotary (FO242) multimode fiber optic rotary joint - Alternative drive coupling arrangements are available (consult factory for specification details) - Tested to 10,000 psi (69,000 kPa) when fluid-filled - Stainless steel and aluminum construction - Connectorized interfaces, for easy fiber cable replacement - Rugged design (MIL-STD-167-1 ship vibration and MIL-STD-810D functional shock (40 g)) TYPICAL APPLICATIONS - Fibre Optic Rotary (FO242) - Remotely Operated Vehicles - Floating Production Systems - Undersea Telemetry - Seismic Streamers - Radar Antennas - Cable Reels Fibre Optic Rotary Joint Model 197 The fibre optic rotary joint Model 197 is a single pass Fibre Optic Rotary Joint (FORJ). The unit is bidirectional and allows the transfer of optical signals across a rotational interface. The 197 offers a high bandwidth and immunity to electromagneticinterference and can be integrated into the standard electrical and fluid sliprings. The unit can also be pressure compensated for submersible applications. The fibre optic rotary joint model 197 is used in a very broad range of applications including ROV handling systems, dipping sonars, towed arrays, wind turbines and industrial robotics. The fibre optic rotary joint unit has a maximum insertion loss of 3,0 dB. Variations of less than 0,2 dB are experienced at 100 rpm for up to 1 million rotations. Fibre Optic Rotary Joint Model 190 The optic rotary joint Model 190 is a multimode unit with up to 12 passes with typical insertion losses of less than 5 dB. The 190 can be integrated with the standard range of Focal electrical and fluid rotary units. The optic rotary joint 190 has the same advantages as the 197 unit and can be fluid filled and pressure compensated. The Fibre optic rotary joint 242 is a singlemode unit that can be delivered with up to 5 passes. Applications include winches for ROV systems, dipping sonars, towed arrays, industrial robotics, turrets, cranes, submarine telescopes and wind turbines. The unit meets a number of demanding MIL specifitcations including MIL STD 167-1 for vibration. FPSO Slip Ring Focal manufacture large composite slip rings for FPSO (Floating Production Storage Offloading) applications. These large units can exceed 8 metres in height and weigh over 25 ton. A typical example, used on a Submerged Turret Production system, transmitting high power at 18,5 MW, including multi pass hydraulic lines and signal rings rated at 500 V at 5 Amp. The complete unit is certified explosion proof for use in Zone 1 hazardous locations. Can be certified to IP68/20 metres. Electrical Slip Ring Model 180 This compact Electrical Slip Ring Model 180 is designed for small systems including ROV systems, oceanographic instrumentation, sonar systems and underwater video cameras. The Electrical Slip Ring Model 180 is rugged and designed for the marine environment backed by ISO 9000 quality. The housing is stainless steel and the bearings are seated for life. The Electrical Slip Ring unit is available with up to 60 circuits, rated 1.000 V at 7 Amp with a maximum rating of 100 Amp per unit. Signal noise is less than 1 microvolt RMS. Options include a bi-directional 1 or 2 fibre optic rotary joint, EEX certification and an electro-mechanical swivel rated for 3 ton. Design life exceeds 5 million rotations at a maximum of 1.000 rpm. Electrical Slip Ring Model 176 This Electrical Slip Ring is normally supplied with a combination of high voltage and low noise signal circuits and up to 12 fibre optic passes. Units are also available with integrated fluid rotary unions. The Electrical Slip Ring Model 176 is used on ROV systems, diving bell handling systems, trenchers, single point moorings, oceanographic systems and geophysical streamer and airgun applications. Power circuits are rated to 3.000 V at 20 Amp and wide band signal circuits have very low insertion loss, crosstalk and VSWR. The Electrical Slip Rings are available for hazardous areas with the appropriate EEX certification and can also be oil filled and pressure compensated for underwater use such as in ROV tether management systems. Electrical Slip Ring Model 159 This unit (Electrical Slip Ring Model 159) has all the features of the Model 176 with the exception of a higher power rating 3.000 V (power rings rated) at 50 Amp. This unit meets the demand of the work class ROV industry where power requirements have increased dramatically over the past years. Purged units are available for all hazardous environments and pressure compensated units are available for underwater use - e.g. on ROV tether management and trencher systems. The high power unit, Model 129 is rated 10.000 V at 500 Amp . Fluid Rotary Union Model 70 The Fluid Rotary Union is developed as an industry standard for the saturation diving market, the Model 70 has found new applications in the geophysical and hydraulic control markets. The Fluid Rotary Union model 70 can be combined with electrical and optical slip rings to produce customized units for special applications. The Fluid Rotary Union is available with up to 12 passes for gases and liquids compatible with 316 stainless steel, Ferralium 255, Rulon J and Viton. All passes can be rated to 200 bar stationary and 68 bar rotating at up to 30 rpm. Standard ports are from ¼" to 1" and standard fittings are S.A.E. straight threads UNF. Helium leakage is less than 10 litres per hour per seal at maximum rotationpressure of 68 bar. There is no leakage between ports. |
