Seaeye Puma
 



Seaeye Puma is depth rated to 1000 metres and provides an exceptional and versatile performance envelope. Two PUMA versions are available. For optimum video capability, three simultaneous video channels are provided via two, dual fibre optic video multiplexers. As a lower cost option, two simultaneous video channels with a third switched television camera can be provided with video transmission via twisted screened pairs, (STP).

Six Seaeye SM4M thrusters, providing additional vertical dynamic lift, power PUMA. PUMA also provides a larger payload than other vehicles of this size, two individually controlled lighting channels, a pan and tilt unit with position feedback of camera angles, an optional tooling skid and greater interface capability for tools and sensors as well as the additional camera capability and fibre optic option. These enhancements are highlighted in italics in this Investment Guide.

A basic ROV system comprises the Surface Power Supply Unit, Surface Control Unit, Hand Controller, and Vehicle unit. The Surface Unit and PSU can be supplied free standing or containerised. This Control Container can be Zone II rated or rated for safe area operations and can be air-conditioned.

Free swimming operations are possible with up to 350 metres of umbilical. For operations with tether lengths greater than 350 metres it is necessary to use the Seaeye Puma Tether Management System (TMS). The TMS is a garage with a bale arm system with a 200 metre tether cable capacity.

A skid mounted 'A' frame and lifting winch with 1100 metres of armoured lift umbilical is offered as a compact combined unit to launch and recover a TMS garaged Seaeye Puma. This can be offered rated for hazardous area Zone II operations or to A60 standard for 'safe area' operations and is known as a 'LARS' or Launch and Recovery System. Alternatively you may have your own crane available and may only require the lifting winch and armoured umbilical with an umbilical sheave and a lock-latch release mechanism and vehicle bullet for launch and recovery.

Propulsion
PUMA is propelled by six highly efficient SEAEYE SM4M brushless DC thrusters. Thruster configuration is four vectored horizontal and two vertical units, providing full three dimensional control

Chassis
A 100% modular chassis manufactured in polypropylene. The extremely rugged chassis is totally maintenance free, non corroding and self supporting in seawater. Additional equipment can be bolted directly to chassis members.

Pressure Housings
All pressure housings are machined from 6082 marine grade aluminium and hard anodised black. The electronics pod has water ingress and vacuum alarms fitted.

Connectors
SEAEYE range of 316 stainless steel connectors are generally used throughout.

Buoyancy
Syntactic foam. A single moulded buoyancy block with apertures for sonar and a tracking transponder or responder.

Control System
16 bit digital system providing easy interfacing to ancillary equipment by the operator. The SEAEYE comprehensive video overlay is fitted as standard providing digital and analogue compass rose, tilt icon, date time group, depth (metric or imperial), CP value ,pre-titled and free text pages. Vehicle data may be exported to clients Survey or Navigation computer systems via the SEAEYE Telemetry Interface Unit in conjunction with a PC.

Navigation
Sensitive flux-gate compass unit with solid state rate sensor for enhanced azimuth stability.

Resolution 0.351
Up-date rate 125 mS
 

Depth Sensor
Electronic unit in its own separate housing. Accuracy 0.1% of fsd.

Auto-pilot
Full automatic pilot is provided for depth and heading.

Pan & Tilt System
SEAEYE Pan & Tilt unit with positional feedback (displayed on the video overlay) is fitted as standard.

Lighting
Two separately controlled lighting channels. Each channel has two fused SEAEYE 150W lamp units. Lamp units can be distributed individually to suit local operating conditions.

Video System
Three simultaneous video channels. One channel has a focus/zoom camera facility. Transmission to the surface is via two dual fibre-optic multiplexers and two fibre optic cores. Two dual fibre-optic de-multiplexers are situated in the Surface Junction Box (supplied) in the ROV control cabin. SEAEYE CCD colour camera is fitted as standard. Two 14 inch colour monitors are also provided.

Surface Control Unit
Contains all vehicle system surface control electronics, TMS control and surface outlets for ancillary equipment. This unit is 19" rack mountable. Supplied in a sealed (when closed) steel enclosure.


Hand Controller and Surface Control Unit

Hand Control Unit
A small remote hand control unit containing all system controls. Unit is supplied on a 5m lead.

Surface Power Supply Unit
Supplies all power requirements for the vehicle system. Line Insulation Monitors (LIMS) are fitted to both AC and DC power components for safety and monitoring purposes. Requires 3 phase AC input of between 380vac and 480vac at 12.5kva.


Power Supply Unit

Tether Management System
Rugged all steel, side entry system using tether cable bailing arm technique (eliminates underwater sliprings). The vehicle is secured within the T.M.S. by a hydrostatic device for launch and recovery. The vehicle can be easily manoeuvred into the T.M.S. either forwards or backwards. Tether cable capacity is 200 metres.
