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: -

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.

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.

Other Equipment Available
Servo-Valve Pack
This extremely compact servo valve pack
weighs only 32 kg in air, 15 kg in sea
water and measures 775 x 198 x 213 mm.
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.

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.
Typical Pump Options Available Sizes (cc)

PRESSURE IS RECORDED DIRECTLY AT MOTOR INLET AND OUTLET ON CALIBRATED
PRESSURE GAUGES. TEST PRESSURE = INLET PRESSURE MINUS OUTLET PRESSURE.

FORWARD TEST SET-UP
MOTOR INLET FLOW IS RECORDED ON CALIBRATED FLOW METER.
OIL TEMPERATURE IS RECORDED FROM FLOWMETER.
CASE DRAINAGE IS RECORDED AT 200 BAR.
OUTLINE TEST PROCEDURE (FORWARD & REVERSE TESTS)
1. SET FLOW RATE AT 5 LPM, SWITCH OFF FLOW AND ALLOW WATER IN TANK TO SETTLE,
SWITCH ON FLOW, RECORD INLET & OUTLET PRESSURES, LOAD CELL & FLOW RATE.
2. SET FLOW RATE AT NEXT INCREMENT (e.g. 7.5 LPM), SWITCH OFF FLOW AND ALLOW WATER
TO SETTLE, SWITCH ON FLOW AND TAKE NEXT SET OF READINGS.
3. REPEAT AS ABOVE FOR FLOW INCREMENT STEPS UNTIL THE MAXIMUM MOTOR PRESSURE IS REACHED.
4. REMOVE TEST FRAME, REVERSE THRUSTER ON FRAME, RELACE IN TANK AND CARRY OUT TESTS
AS ABOVE TO CHECK REVERSE BOLLARD THRUST.
