Sub-Atlantic's new direct drive range of brushless DC thrusters break new ground in thrust, low weight and enhanced reliability. They are currently available in four sizes, each incorporating Sub-Atlantic's unique Statorshield™ technology. ■ High Reliability, Rugged Design ■ Unique Statorshield™ Technology Event of Shaft Seal Failure ■ Forward / Reverse Thrust within 5-10% Band ■ Four Sizes Available ■ Direct Drive Reliability (no gearbox) ■ Integral Drive Electronics ■ Various Connector Options ■ Various Voltage Options Sub-Atlantic's unique Statorshield™ system allows the thruster to continue running in the event of a shaft seal failure and subsequent flooding, without damage to the winding or electronic components. Integral electronic drives are oil filled and pressure compensated to 3000 metres / 10,000 feet. Four sizes are available with propeller diameters up to 380 mm / 15" and bollard thrusts up to 220 kgf / 485 Ibf.

Supply Voltage Statorshield™ Technology Subsea thrusters are prone to water entering through the shaft seals and causing short circuit failure of the stator windings. Statorshield™ technology eliminates this problem by the introduction of an internal Innovative Shaft Sealing The thruster incorporates our proven ceramic wear ring technology used on all our current electric and hydraulic thrusters. The ceramic ring provides a durable hard surface that prevents wear resultant seal damage Integral Drive Electronics All thrusters (except the SPE-380) have ntegral drive electronics built into the housing....

Available Sizes ■ Standard range is available in four millimetres. Standard motor sizes cc. Our hydraulic motors all have identical mounting interfaces to the thruster body, no matter the motor displacement. This makes them particularly suitable for interchanging with different propeller sizes to obtain higher running efficiencies. For example, in an application where limited hydraulic power and oil flow is available but maximum thrust is required, an SA-380 thruster (which normally uses a 40cc motor) can be simply fitted with a 30cc motor using the larger propeller, increased efficiency can...

Live Boat or TMS Operation The Comanche can be free-flown in 'live boating' mode or with our cage type TMS systems (see TMS data sheet). The smal diameter tether allows long cable excursions. Compact Control Surface equipment consists 3 units ■ Surface Control Unit (SCU) - Hand Control Unit (HCU) ■ PDU (Power Distribution Unit). The SCU is generally supplied as a portable flight case system. Alternatively, the 8U x 19" rack mount control module can be supplied loose for fitting into customers own control compact for operation in small control spaces. The three units are linked by interconnecting...

Reliable Thrusters Comanche uses a 7 thruster configuration to provide maximum horizontal and vertical lifting capability. a 45 degree vectored configuration producing very high all round thrust. ■ 3 xSPE250 vertical thrusters, 1 vectored outward at front to clear the vehicle lower deck (leaving it free of cut-outs in way of tools and skids) and a single pitch thruster at the rearto counteract manipulator loading effects. reliability brushless DC thruster develops 100 kgf(220 Ibf) of static thrust in both directions. It incorporates our unique 'Statorshield™ technology that allows the thruster...

The Sub-CAN control system is a modular design based around the multi- drop network CAN (Controller Area Network). Modules can be added or taken away depending upon the control system requirements; providing commo- nality of parts and spares.
