Performance Hydraulic Propulsion Selection Manual for Engineers Revision 3 APR. 2003 Revision Record Rev 1 2 3 Description Original SA300-20 and SA380-40 data added Sa420-40 data added By cmi cmi cmi Date Dec 02 11/04/03 Propulsion Products Since their launch in 1998, SubAtlantic's 'SA' range of hydraulic thrusters have been selected for approximately 90% of new build cable burial/maintenance vehicles. Working in this highly aggressive environment, they have become renown for their reliability, efficiency and exceptional performance. The ROV sector is now also recognising the considerable benefits to be gained, having been selected for the majority of 'new design' systems such as Stolt Offshore’s, ’SOLO Mk II’, Thales Geosolutions’s ‘G3’ or Deep Ocean’s ‘Installer’. 'SA' Range of Hydraulic Thrusters We offer a 'Preferred Range' and a 'Non-Standard Range' of hydraulic thrusters. Our 'Preferred Range' is available in four sizes, SA300-30, SA380-40, SA42060 & SA500-110, where the first number represents the diameter of the propeller in millimetres and the second, the motor displacement in cubic centimetres. The SA300 and SA380 units are usually used on work ROVs, the SA420 and SA500 for cable ROVs. Our 'Non-Standard Range' is available in a number of different options of motor displacement, propeller size, motor manufacturer and mounting style. In certain cases, we can also produce specials to customer’s requirements. Details of the SA-300-20cc and SA-380-30cc are shown in this manual. When selecting hydraulic propulsion thrusters for an underwater vehicle design, many highly important 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 your expectations. During the development phases of the 'SA' range, Sub-Atlantic evaluated various competitor's thruster products. We found that the actual test results and weights proved to be vastly different from the data claimed in their technical publications. Infact, some of the data proved to be theoretically impossible to achieve. Sub-Atlantic therefore introduced a policy to ensure that all our own test performance data was witnessed by a reputable third party certification organisation (DNV). It is this commitment and confidence 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. If they can't provide it, ask the question "why not"! Main Features In addition to peace-of-mind, our hydraulic thrusters will provide you with the following benefits: Proven Reliability Originating from the design of the shaft sealing system which utilises hard, non-wearing ceramic and PTFE materials. Secondly, a rugged VOAC bent axis piston motor is used, capable of clocking up tens of thousands of trouble-free hours. We know SA thrusters are reliable because we sell very little spare parts! More Efficient Our thrusters convert more thrust from the available hydraulic power supply. Superb Forward/Reverse Characteristics 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, SA performance far exceeds other thrusters on the market. Check out the comparison graph. Lighter This means less ROV buoyancy required, less in-water drag leading to more usable thrust which means you will still be working when the increasing current puts the other back on deck. DNV Witnessed Performance Unlike some others, our thusters will perform just like we say they will. Retro-Fittable SA thrusters use common mounting configurations so ROV performance upgrades are easy. Preferred Range The standard Range consists of the following four units: - Preferred Range Model SA-300-30 SA-380-40 SA-420-60 SA-500-110 Propeller Diameter mm 300 385 420 500 Motor Displacement cc 28.1 37.7 58.2 110.1 Bollard Thrust @ 250bar kgf 370 460 590 850 Weight in Air kg 18 27 34 59 Weight in Water kg 10 14 17 31 Mount Flange Flange Flange Flange These are the most common types available and should be selected where possible. Non-Standard Range Different Motor/Propeller Combinations The VOAC motors used 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-380-40 thruster (which normally uses a 37.7 cc motor) can be simply fitted with a 28.1 cc motor and used instead of an SA300-30. By using the larger propeller, increased efficiency can be achieved without the requirement for more oil flow. Details of these are shown in this manual. SA-300/1002-(20 or 30) This is a version of the SA-300 with special mounting configuration to fit Innerspace 1002 brackets. This is a particularly useful option for carrying out a quick retrofit on ROVs with frames with permanently welded thruster brackets such as 'Cobra'. Four to eight mounting studs can be positioned to suit. The motor can be 20 or 30cc displacement depending on the oil flow available. Non-Standard Range Model SA-300-20 SA-380-30 SA-300-1002-20 SA-300-1002-30 Propeller Diameter mm 300 385 300 300 Motor Displ. cc 19.0 28.1 19.0 28.1 Bollard Thrust @ 250bar kgf 230 330 230 370 Weight In Air kg 17 26 17 18 Weight in Water kg 9 13 9 10 Mount Flange Flange Innerspace Innerspace Different Motor Manufacturers Thrusters are also available with conversion kits which allow different motors to be used, such as Rexroth. Contact and we will advise you of these options. Special Sizes In certain cases, we may be able to supply special sizes. Testing Sub-Atlantic thrusters are tested at a depth of approx. 2.7 metres below the surface. The general procedure is illustrated on Drawing No. 0438-GA attached. All testing is witnessed by DNV who issue a certified certificate of authenticity.

This valve pack is generally used to provide precise control of the propulsion thrusters on underwater vehicles. The pack utilises 77 LPM rated servovalves which provide low pressure drop on most standard ROV applications. The use of this pack in conjunction with SubAtlantic's efficient thrusters and hydraulic power units, will produce an unbeatable propulsion solution with regard to reliability, efficiency and cost. The valves can also be used to control any tool requiring a vazriable speed or reversible function.The unit can use Star or Moog (Ultra) valves. Unless specified, Sub-Atlantic supply the Star valve as standard as this is half the weight of the Moog. Both types of valve are functionally identical and interchangeable.

No. 1218-UM 75 & 110 kW Hydraulic Power Units (HPU) These HPUs are ideal for driving thruster systems and hydraulic tools requiring higher power inputs. The submersible motor unit can also be used to drive other types of rotating machinery such as water pumps for trenching machines. The motor uses a Zeihl-Abegg rotor/stator unit which has for many years been successfully used in the ROV industry. The standard motor is 4 pole, 3000 vac running at 1700 rpm full load speed @ 60Hz. Other voltage and speed options are available on request. The motor body and end cap design provides for efficient heat dissipation, which is essential when working in hot climates. Motor winding temperature and water ingress sensors are included for connection to customers control system. The motor is filled with transformer or hydraulic oil which must be positively compensated (compensators are available, see Hydraulic Products Brochure). Various hydraulic pumps can be fitted to the motor by means of an Interface Plate. A secondary pump can also be fitted to the opposite end of the motor to provide a separate isolated hydraulic circuit. Compensated pumps are generally used which automatically 'unload' when there is no power demand. Pumps from different manufacturers such a VOAC or Rexroth in various sizes and control options can be supplied fitted and ready to run.
