Innovative Shaft Sealing

Depth Rating

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 to shaft and the resultant seal damage and consequential ooding.

Thrusters are rated to 3,000 metres / 10,000 feet which is currently limited by the integral oil compensated drive electronics. Rating can be increased to full ocean depth by placing the electronics in a one-atmosphere housing.

Integral Drive Electronics All thrusters (except the SPE-380) have integral drive electronics built into the housing. Electrical connections consist sealed diaphragm located between the rotor and stator, creating two separate isolated and sealed volumes (Rotor cavity and Stator cavity). Water cannot reach the stator and electronics through the shaft seal preventing a catastrophic failure due to shaft seal leakage. Operation can continue until the machine is recovered when the rotor cavity can be ushed, seals replaced and re lled with oil.

Pressure Compensation Both the Rotor and Stator cavities are compensated separately. The rotor cavity by a integral compensator on the rear of the thruster while the stator cavity must be compensated by a separate external unit. A range of Compensators are available from Sub-Atlantic..

Electrical Connector of main DC power input and a control signal. The control is analogue (+/- 5 Vdc) but serial and CAN control is also available on some thrusters (see table above).

Thrusters can be supplied with either Tygon oil lled cables or standard cable whips with end connections to suit customerâ&#x20AC;&#x2122;s requirements.

Hydraulic Thrusters Sub-Atlantic’s range of hydraulic thrusters have become the preferred propulsion for ROVs and cable burial/maintenance vehicles. Working in a highly aggressive environment, they have earned a reputation for reliability, efficiency and exceptional performance.

Sub-Atlantic hydraulic thrusters are reliable due to a rugged, lightweight contruction and a ceramic shaft sealing system. These thrusters also beneÀt from producing near equal forward/reverse efÀciency within a 5% band. The data from our performance testing has been witnessed by DNV to ensure your system design performs exactly as expected. These thrusters also beneÀt from the ability to Àt any motor displacement size to any of the four thruster sizes due to the common, one-size motor/thruster interface. This is advantageous when accuratly matching to vehicle hydraulic system parameters.

Standard range is available in four propeller sizes, SA300, SA380, SA420 & SA500, the designation represents the diameter of the propeller in millimetres. Standard motor sizes are 20, 30, 41, 61, 103 and 119 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 ow is available but maximum thrust is required, an SA-380 thruster (which normally uses a 40cc motor) can be simply tted with a 30cc motor and used instead of a SA300-30. By using the larger propeller, increased ef ciency can be achieved without the requirement for more oil ow.

SA300, SA380 and SA420 units are generally used on work ROVs, SA420 and SA500 generally for cable ROVs. Options of motor displacement, propeller size, motor manufacturer and mounting style can also be supplied. In certain cases, we can produce specials to customer’s requirements.

DNV Witnessed Test Data When selecting hydraulic propulsion thrusters for an underwater vehicle design, many highly impor tant considerations such as efficiency, pressure and flow, weight, size and forward/reverse characteristics must be taken into account. Failure to correctly interpret these or to use inaccurate data will result in a system with inferior

performance and incapable of meeting expectations. During the development phases of the ‘SA’ range, Sub-Atlantic evaluated various competitors’ thruster products. We found that the actual test results and weights proved to be vastly different from the data claimed in their technical publications. Sub-Atlantic therefore introduced a policy to ensure that all our own test performance data was witnessed by a reputable third party certi cation organisation (DNV). It is this commitment and con dence in our product that will give you peace-of-mind. Remember and ask for independently witnessed test data before you purchase your system or better still, test it yourself.

Comparing input power to the output thrust, our forward and reverse thrust curves fall within a 5% band. This is important in a typical vectored configuration as the overall system performance will only be as good as the average forward/reverse thrust. For the same power input,performance exceeds other thrusters on the market.

Comanche incorporates a fully electric, seven thruster propulsion system, conÀgured to provide high thrust and lifting capability. It uses a 3000 Volt, 400 Hz power transmission system from surface to ROV resulting in a small tether, main lift cable and launch/recovery system. This transmission system makes it particularly suited for long tether excursions and deep live-boating operations. Comanche is equipped with additional power sources to allow the use of a 15 kW / 20 hp hydraulic power unit for running tools and work skids and for rig support intervention tasks. When compared with hydraulic work-class systems, the Comanche provides important customer beneÀts with regard to capital and operational expenditure, simplicity of use and requires less deck space.

Comanche uses a 7 thruster conłguration to provide maximum horizontal and vertical lifting capability.

Comanche deliveries from 2008 will include our newest technology SubCanTM control system.

4 x SPE250 horizontal thrusters in a 45 degree vectored conłguration producing very high all round thrust. 3 x SPE250 vertical thrusters, 2 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 rear to counteract manipulator loading effects.

Simple, Intuitive Control GUI

SubAtlantic’s SPE250 highreliability brushless DC thruster develops 100 kgf (220 lbf) of static thrust in both directions. It TM incorporates our unique ‘Statorshield technology that allows the thruster to continue working in the event of water ingress past the shaft seal.

feedback such as heading, pitch, roll, etc. are displayed on a 17 inch touch screen monitor. The touch screen also enables the operator to access setup and diagnostic information relating to the inner workings of the control system. The GUI pages are arranged in a hierarchical order with the top page providing the ‘day to day’ control of the ROV. The top page displays various alarm information for rapid fault diagnosis of the control system sub-assemblies and components. Diagnostic information from each control sub-system, ROV, TMS and Surface can also be accessed from this page.

problem by the introduction of an internal sealed diaphragm located between the rotor and stator, creating two separate isolated and sealed volumes (Rotor cavity and Stator cavity). Water cannot reach the stator and electronics through the shaft seal preventing a catastrophic failure due to shaft seal leakage. Operation can continue until the machine is recovered when the rotor cavity can be Ńushed, seals replaced and rełlled with oil.

The topside graphical user interface and the hardware controller are designed in such a way as to enable the operator to control the ROV in the simplest and most effective manner. ROV control
