The smallest inspection class ROV in the market place (190mm fly through). The AC-ROV is more powerful, more robust and a more cost effective solution than all other ROVs in its class.

These facts however are secondary to the real capability of the AC-ROV. All underwater ROVs have a flight pattern that reflects the movement of an aeroplane (3 degrees of movement) - this means that when inspecting or observing a target the ROV must constantly move in and then away to take up a fresh viewing position. The AC-ROV however has the underwater flight pattern of a helicopter - this allows the ROV to hover, circle, rotate on its axis and move in any direction the target requires. This breakthrough is achieved by six internally housed thrusters that produce five degrees of movement.

With an operating depth of 75-100m, a total system carry case weight of under 15kg, and a service life of 200-300 hours at 100% duty (continuous full depth & full speed), the AC-ROV has been designed for inspection in hazardous and confined areas.

The AC-ROV has a two- function manipulator (option). The manipulator combines grip and full continuous wrist rotate via a ground breaking drive-train, resulting in the smallest two-function manipulator in the ROV market. Consisting of titanium, aluminium, stainless steel and plastic components, the AC-ROV micro-manipulator system comes completely integrated into its own bottom buoyancy block. There are no underwater cable connections thus limiting snagging potential, while the integrated nature of manipulator and block gives the system inherent strength and robustness - a feature demonstrated by all AC-ROV components. Simply remove the standard bottom block from your AC-ROV and fit the manipulator block, the manipulator is 100% interchangeable between individual AC-ROV units, giving maximum functionality and cost savings. Topside control is a thumb activated one handed joystick controller that simply connects directly to the control box without need for modification, with all manipulator operations viewed via the state of the art camera system. Two and three jaw options are available and customers can specify special gripper heads for specific jobs. Three screws secure the jaw assembly to the arm and change-out could not be easier.

Notes.

1. Flight assist controls include; Flight Freeze & Un-freeze / Progressive +/- Vertical Trim / Progressive +/- Pitch / 3 stage Power Increment. All these functions are programmed on the hand controller. Light dimmers are incorporated on the control box.

2. The AC-ROV thruster does not have a centre and the inward pointing blades do not meet. The full-bore unrestricted flow path maximises thrust and is relatively self-clearing in weed type environments.

3. The tether cable and connectors are field serviceable, given that the operator has basic electrician skills. Any damaged cable can be cut out and any remaining serviceable cable re-terminated and used again without the need for specialist cable moulding services.

4. Connect a PC or Laptop computer with video grabber, or a video recorder for video recording and data logging.

A computer is not required for normal operation nor included in the supply.

- DC power supply

The principle elements of the system are the surface electronics control and patch drawers. These house the surface multiplexer, surface interface board and cross connect area that links individual components to form the control and signal interfaces.

The upper right hand drawer contains the power supply units, the multiplexer chassis and control components. The multiplexer chassis is connected by ribbon cables via the patch drawer to the operator control unit. This arrangement connects the analogue, control and miscellaneous commands from the operator via the following input devices:

- Joysticks
- Trim Controllers
- Lighting Potentiometers
- Sonar Deployment Control
- Digital input switch matrix
- Manipulator control switches

Analogue command inputs are routed to the patch drawer where some of the signals are diverted for conditioning or interface with the attitude display processor.

Vehicle motion control signals, joystick commands and trim voltages are routed to an interface board that is a 37 way module located in the patch drawer. This set up allows the signals to be summated and calibrated for offset or gain prior to transmission to the vehicle control system via the data multiplexer.

Analogue output channels from the multiplexer are routed within the surface electronics unit, then transferred to the computer for processing and display on the attitude and status indicators.

2.6 Surface Multiplexer

The surface telemetry control subsystem is built into the electronics unit. The subsystem comprises a multiplexer chassis that consists of a set of printed circuit boards housed inside the surface electronic unit.

The set of PCB’s comprises:

The slipring unit is mounted on the winch drum axis. Internal leads from the sliprings are linked to the rotating junction box to which the Rov umbilical is connected.

3. Rov Umbilical

There are two types of Rov umbilical cable available to suit specific operational requirements. One type is steel wire wound whilst the other is Kevlar braided.

Both types of umbilical transmit the power, data, and video signals to and from the Rov.

4. Deployment System

Deployment and recovery of the Rov is by means of a Latch – Lock system that also acts as a guide for the umbilical. The latch – Lock dogs are hydraulically operated by means of an Enerpac hand pump.

Depending on the configuration of the support vessel either an “A” frame or an articulated crane may be used to deploy the Rov.

5. Remote Operated Vehicle

The Rov is a heavy-duty underwater vehicle designed to complete a wide variety of tasks to a depth of 1000m.

5.1 Rov Main Frame

The Rov frame is an open frame design, constructed from HE30 aluminium I beam and channel that give good strength to weight ratio. The frame is fitted on the base and outer surfaces with HDPE rubbing strips to protect it from damage during deployment and recovery. HDPE is a buoyant material when in water therefore adding no weight to the vehicle when sub sea.

5.2 Buoyancy

The vehicle is held in a vertical attitude by means of six contoured blocks of elastomer coated syntatic foam. There are three on each side of the top frame.

5.3 Electronics

The operating system has been designed around hardware driven Time Division Multiplex (TMD) telemetry datalink. The system is half duplex and provides a reliable communications link between the surface control equipment and the vehicle control / sensors system.

The vehicle primary electronic control and interfacing components are mounted inside two electronic pods. Connections to the external equipment are made through 24 pin Burton sub sea connectors.

Penetrators are placed radially on the pod end dome and each has a connector re mounted on the forward face. Each connector receptacle mates to a matching cable plug on the cable assembly.

Hyball is a compact, portable system comprising the Remote Operated Vehicle (Rov) and a Surface Control Unit with built in colour monitor, and all Rov controls.

An appropriate length of umbilical connects the Rov to the Surface Control Unit providing the telemetry, power and video link between the two units. Hyball comes standard with the most comprehensive video overlay of any Rov in its class and all the auto functions that you would expect of a professional system. Useful accessories can be added to the system to extend its operational capability.

Hyball’s unique feature is the patented meridian view port that allows the internally mounted camera to tilt and view through 360 degrees. Panning of the camera is achieved by rotating the vehicle, which can turn on its own axis. This combination of camera movement and vehicle maneuverability provides you with the ideal remote controlled subsea video inspection package for coastal and inshore applications. In Hyball we provide you with the very latest in colour video cameras for unbeatable video quality. Currently we provide a JVC 470 line resolution, 0.95 lux colour CCD camera with an F 0.8 Pentax lens as the standard video camera.

Propulsion
Hyball is fitted with four thrusters. Two main thrusters provide forward, reverse and rotational movement and two vertran thrusters provide vertical and lateral movement. Each has 5-inch diameter propellers in Kort Nozzles driven by 380 watt (1/2hp) 24 volt DC motors through 10.5:1 reduction gears.

The carbon/ceramic spring loaded shaft seals and motor brushes have a service life of 500 hours in normal operation down to 300 metres (1000 feet). They can be replaced on all four thrusters in less than an hour by removing the thruster from the outside of the vehicle. Thruster speed and direction is controlled by digital signals proportional to the movements of the joystick. Built in protection prevents overheating and overloading of motors. Ramping of motor speed is software driven through a dedicated microprocessor to give smooth operating performance.

Lighting.
Hyball is equipped with two fixed 75 watt, quartz halogen lights aimed forward and two 75 watt lights mounted on the camera chassis. These camera chassis lights track with the camera. All light bulbs are easily replaceable in the field. Each light is individually controlled and has an on/off indicator on the video overlay. Light intensity is adjustable from the Surface Unit keypad.

Viewing System.
Hyball is equipped with a low light CCD colour video camera with a wide angle, auto iris lens. The camera is mounted on a chassis, which rotates through 360 degrees and allows the camera to view up, down, forward or backwards through a unique, patented Meridian view port.

The video picture is sent to the Surface Unit and is displayed on an integral 14-inch high-resolution colour monitor. Either PAL or NTSC format is available. A BNC outlet is provided for a video recorder. We recommend that an S-VHS or Y/C video recorder be used that is capable of recording the high quality video from Hyball, which has greater than 460 line resolution. (A standard domestic VHS recorder can only resolve about 270 lines resolution). Three cameras can be mounted on the standard camera chassis - the standard camera, a low light monochrome camera and a photographic camera.

Sensors.
Hyball is supplied with a full package of control and instrumentation sensors:

Depth.
The Digital Depth Indicator is selected by the operator to readout in feet or metres, salt or freshwater. The vehicle's depth is then displayed on the video overlay.

Direction.
Hyball is equipped with both a magnetic compass and a rate gyro. The compass heading is displayed on the video overlay compass rose and can also be displayed as a digital heading. The rate gyro is used to control auto heading when this function is selected.

Camera Position.
A potentiometer on the camera chassis provides feedback to display camera tilt position on the video overlay. This is very useful for orientation during flying as well as video playback.

Leak Detection.
Pre dive water integrity is confirmed by drawing a partial vacuum in the vehicle using the supplied vacuum pump. This partial vacuum is displayed on the video overlay and can be monitored to ensure that there are no system leaks. The vehicle is also fitted with a water ingress alarm as an additional safety feature.

Electrical Protection.

Ground fault interrupters and circuit breakers are installed to protect both the surface unit and the vehicle.

Video Overlay.
Hyball comes with the most advanced video overlay system of any Rov in its class. The overlay information can be displayed at the top or bottom of the screen or be removed. Information provided includes:

Vehicle heading, depth, time and date.
Auto heading and auto depth status
Lights selected and intensity
CP reading (if CP probe fitted)
Manipulator open/close (if fitted)
Camera position indicator
Camera selected (A or B)
Umbilical turns counter
And two lines of free text

Controls.
A single, three-axis joystick and dive/surface buttons on the hand controller control the vehicle's movement. Any combination of vehicle thruster instruction (except rotate) can be locked in by use of the trim button. This is useful for hands-off operation or for re-centering the joystick when operating in a cross current. Vertical thrust power is selected from the surface unit panel. Membrane tactile response keypads are provided on both the surface unit and hand controller.
