Marine & Energy Over the years, we have had one focus and that is answering the global demands for innovative power and data transmission solutions. In 2005, Focal Technologies was acquired by Moog Inc. and became part of the Moog Components Group business segment. By combining these leadingedge companies, new strengths and resources emerged. The Focal™ product line continues to solve the demanding challenges of the marine and energy industry. Electrical Slip Rings Designed to function in extreme marine environments, our electrical slip ring units are used around the world for reliable power...

Our approach to solving power and data transmission challenges is simple - innovation and performance in all that we do. That means products that consistently perform in the world’s harshest environments. People that consistently exceed expectations. And innovative custom solutions and services that set the pace in today’s rapidly changing global markets. We have delivered trusted technology products and services to the offshore petroleum, oceanographic, seismic and maritime industries for more than 20 years. Working from our well-equipped facility in Halifax, Nova Scotia, Canada, we have earned...

Electrical Slip Rings Designed to function in extreme marine environments, our electrical slip ring units are used around the world for reliable power and signal transmissions in marine surface and subsea applications. With a diameter of 12.8 inches (32.5 cm), this high power unit is designed to meet the needs of high current, heavy-duty applications. Similar to the Model 176, the Model 159 can be designed for higher current applications. Each pass can be rated up to 50 amps. Note: Selected slip ring photos are shown without their standard stainless steel enclosure for clarity.

Diverse Applications Used in the majority of current work-class ROV models and underwater trenchers, geophysical, oceanographic and other winches, our electrical slip ring units are customized for the most demanding environments. The Model 176 is a versatile design found in applications as diverse as Remotely Operated Vehicle systems, both surface and subsea, towed arrays used by various navies, seismic exploration, subsea control systems and oceanographic monitoring installations. The Model 180 is used in smaller winch systems such as those for oceanographic sensors and small ROV systems. In...

Fiber Optic Rotary Joints We focus on the rotary interface needs of the marine and energy industries. Our fiber optic rotary joints (FORJs) are recognized around the world for innovative performance and reliability in harsh marine environments. This multi-pass,multimode model has an excellent service track record. The Model 190 can accommodate a variety of fiber types and wavelengths in one unit and its modular design makes it easy to customize for any application. A rugged, high performance single-pass multimode model with a typical insertion loss of 1.5 dB and capacity for several types of...

Experienced Innovators Our company’s reputation for innovation grew when we were the first to develop FORJs for marine applications. Today, we are still recognized as industry leaders. As the developers of the first commercial multi-pass, multimode and singlemode FORJ, as well as a collection of features responsive to the needs of the marine and energy industry, we are continually setting new standards. The Model 291, for example, allows up to 9 passes in a housing less than 2.5 inches (6.4 cm) in diameter. Recent product development also includes a variety of single and multiple channel devices...

FPSO Swivels We have designed, manufactured and delivered more than 40 large, complex FPSO swivel assemblies to offshore operators worldwide. Our custom assemblies allow 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. Typically comprised of electrical slip rings, hydraulic utility swivels and fiber optic rotary joints, our swivel assemblies are used in a variety of FPSO systems and are certified for use in hazardous environments. The units within the swivel assemblies...

Fluid Rotary Unions Introduced in the mid 1970’s to serve in diver life-support umbilical systems, our fluid rotary unions have been diversified to include a broad range of applications. Our 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...

Fiber Optic Multiplexers and Media Converters Our multiplexers were developed to provide reliable fiber optic transmission of video and data signals in the demanding subsea applications of ROVs, robust defense systems, and other platforms operating in harsh environments around the world. This Eurocard-based rack system features redundant fiber options, extensive protection and isolation circuits, and advanced PC-based diagnostics. CWDM and DWDM versions provide system expansion up to 32 video channels, and hundreds of data channels with support for many types of media converters. Multiplexer...

A Solution for Every Fiber Optic Telemetry Requirement Our multiplexers use both time division multiplexing (TDM) and wavelength division multiplexing (WDM) to exploit the huge bandwidth of fiber optic cables, combining all video / data signals on to one or two fibers. Advances in coarse wavelength division multiplexing (CWDM) and dense wavelength division multiplexing (DWDM) expand the data carrying capacity of fibers to accommodate the ever-increasing data rates needed for digital video, high resolution sonars and sensors, and high speed networks, such as Ethernet and IEEE-1394 (Firewire)....
