Construction

Wright International Ltd is delighted to be able to bring an ROV that is reliable, portable, affordable and rugged enough to be used in the most demanding of circumstances. This WIL 2038 ROV has a number of interesting innovations for an ROV of this size and price range including the replacement of the ROV electronics pod with a distributed intelligence control system and new high torque magnetically coupled brushless DC thrusters. The ease with which tools and sensors can be added to this modern open frame vehicle without upsetting its performance and stability has also found favour with scientists, environmental groups, civil engineers and deep penetration internal tunnel surveyors.

CHASSIS LAYOUT
This ROV has an extremely rugged polypropylene chassis with a stainless steel lift frame. This material is robust, buoyant, easily drilled and machined and is corrosion free. This modern 'open frame' design allows the easy addition of standard bolt on accessories including cameras, sonars, tracking systems and a single function manipulator. Custom designed under-slung modules can also be added for task specific tooling. 316 stainless steel fittings are used throughout. The core frame is manufactured using modern composite materials.

BUOYANCY & PAYLOAD
Buoyancy and payload is provided by securing buoyancy blocks of the appropriate depth rating to the chassis below an easily removable hydrodynamic faring. The faring cover also provides protection to electronics housings and cables routed along the top of the buoyancy to the junction box. Mounting points on the vehicle skids are provided for lead ballast to trim the vehicle's centre of gravity and buoyancy.

WIL 2038 PROPULSION
Brushless DC thrusters have been used on these ROVs since 1987 when the company first introduced this technology to the offshore oil & gas industry. These thrusters have drive electronics with velocity feedback for precise and rapid thrust control. A fast PID control system and a solid-state rate gyro for enhanced azimuth stability prevent overshoot on a change of heading as well as helping stabilise the vehicle in forward flight making the vehicle so easy to fly.

The thrusters are magnetically coupled and run cool without oil. Having no moving shaft seals they are extremely low maintenance, reliable and ideal for use in sensitive areas such as fisheries and on reefs. The open frame and clutter free layout between decks in the ROV provides the clearest water flow to 4 horizontal vectored thrusters positioned for optimum thrust and control in all directions and superior station keeping in strong cross currents.

These ROV`s are powered by 5 Magnetically Coupled Thruster units (MCT1) each capable of achieving 13 kgf thrust at 320W or a combined forward thrust (bollard pull) of 50 kgf. For an ROV weighing only 50 kilos this represents an impressive 1:1 power to weight ratio.

DISTRIBUTED INTELLIGENCE CONTROL SYSTEM & ROV JUNCTION BOX
This WIL 2038 is the first ROV in its class to have a distributed intelligence control system. This is a multi-drop network that allows up to 128 devices to be connected together on a single serial network and to be individually controlled by a master processor.

Every controllable device on this ROV, such as thrusters, lights, camera tilt motor, navigation pod and manipulator pod, contains its own microprocessor and interface and is called a 'node'. Each of these 'nodes' is separately addressed on the network and controlled by the master processor in the Surface Unit. Every node is fully isolated to maximise system reliability and each is connected into the vehicle junction box PCB using a common through bulkhead connector. The printed circuit board provides each node with its own fused power supply and telemetry.

The Junction box also houses the video line driver for ROV and the Fibre Optic Multiplexer is an optional upgrade for the standard system. This use of distributed intelligence does away with the traditional ROV electronics pod packed with interface circuit boards and frees up space while significantly reducing the weight of the vehicle.

Control System Diagnostics
Full system diagnostics are provided: A software routine automatically checks each node when the system is powered up and alerts are provided on the video overlay to warn the operator. The full characteristics of each node can also be interrogated individually from the surface unit. Local diagnostics are also provided for each node in the Junction Box with colour coded LEDs confirming fuse and telemetry status.

Camera System
A high resolution fixed focus colour camera is fitted to a camera platform than can be tilted + 90 degrees. An additional switched camera can be added to this ROV and is usually mounted on the underside of the camera tilt platform.
