The Seaeye Cougar-XT Compact is the shallow water compact version of the field proven and extremely powerful Cougar-XT.

Proven worldwide and recognised for its capability, operators now have the ability to undertake a range of demanding observation and light work tasks at much lower operating costs.

Saab Seaeye recognised the need for a high performance ROV in the renewable energy markets, for shallow water cable laying and inspection tasks, where strong tidal currents are experienced.

The smaller chassis results in a significantly lower profile to reduce drag, in combination with a high performance thruster arrangement and a low resistance tether, offers the market an ROV system with unrivalled performance for its size and class.

The extremely rugged polypropylene and stainless steel chassis is totally maintenance free, non corroding and self-supporting in seawater. Additional equipment can be bolted directly to the chassis for customisation.

The syntactic foam buoyancy block has apertures for a sonar, emergency strobe and tracking transponder.

Four vectored horizontal and two vertical brushless SM7 500 Volt DC thrusters provide full three-dimensional control of the Cougar-XT Compact and one of the highest thrust to weight ratios in its class.

Compass Rate Gyro & Depth Sensor
A flux-gate compass and a solid-state rate sensor give superior azimuth stability.

Specifications Seaeye Cougar-XT Compact
Compass accuracy ± 0.5°
Resolution 0.351°
Update rate 98 ms

The system uses an electronic depth sensor accurate to ±0.1° FSD accuracy.

Autopilot Functions

  • Auto heading
  • Auto depth
  • Auto altitude (optional)

Video System
Up to four simultaneous video channels are available (transmitted via two multimode fibres).

Equipment Interfaces
A wide range of standard or custom interfaces are available for:

  • Cameras
  • Manipulators, cutters
  • Sonar systems (obstacle avoidance, multibeam, side scan)
  • CP probe
  • Auxiliary connections (RS232/RS485/STP and optional Ethernet)
  • Emergency strobe
  • Tracking system
  • Tooling motor

Seaeye Cougar XT Compact Tilt Platform

Tilt Platform
The ±90 degree camera tilt platform accepts two cameras and a light. A proportional tilt feedback potentiometer provides an accurate tilt angle which is displayed on the video overlay.

The Cougar-XT Compact is fitted with four long-life LED lamps (on two individually controlled channels). They provide excellentillumination with very low power consumption, are exceptionally robust and practically maintenance free.

Vehicle Electronics Pod
The vehicle has a watertight and anodised electronics pod machined from 6082 marine grade aluminium and fitted with leak and vacuum alarms.

The Cougar-XT Compact uses Seaeye's field proven range of metal shell connectors.

Tether Termination
The tether is electrically terminated in an oil-filled and pressure compensated vehicle junction box and mechanically supported by a cable-grip.


Seaeye Cougar-XT Compact Surface Control Unit

Surface Control Unit
Surface control equipment can either be installed directly in the customerís facility or integrated into a custom ISO control cabin.

The surface control system provides:

  • AC and DC supply switching control
  • DC current and voltage indication
  • Control of video and video overlay
  • A keypad for system configuration
  • Interfaces for ancillary equipment
  • ROV control system (via the hand control unit)

Seaeye Cougar XT Compact Monitor and Video Overlay

Monitor and Video Overlay
The system comes with two 17" colour rack-mounted video monitors displaying the video signal from the cameras. One also displays the following overlay data:

  • Heading
  • Analogue compass rose
  • Depth
  • Tilt position
  • Date and time
  • Free text from keyboard
  • CP probe readings (if fitted)
  • Vehicle turns count
  • Leak & vacuum alarms
  • One string of live data, e.g. altitude or latitude/longitude (optional)

Telemetry Monitor Unit
A telemetry monitor unit allows the ROV data (heading, depth, etc) to be displayed on a PC and/or exported to a survey computer, and is also a useful diagnostics tool.

Seaeye Cougar-XT Compact Hand Control Unit

A rack-mountable keyboard is supplied for entering data and free text onto the video overlay.

Hand Control Unit
The hand control unit provides remote control of the ROV (propulsion, tilt unit, lights, autopilot functions, etc).

Seaeye Cougar-XT Compact System Power Supply

System Power Supply
The power supply unit incorporates protection devices, interlocks and cooling fans. Safety features include both AC and DC line insulation monitors (LIMs) to monitor electrical leakage in the system (with trips and alarm indicators) and to test the isolation of the system.

3-Phase 9 kVA Tooling Power Supply Unit
This unit provides a 3-phase 660V power supply at the vehicle for optional tooling, such as cutters or water jetting systems.

Cabin Junction Box
At the surface the umbilical cable is terminated inside a lockable cabin junction box, which also contains the fibre optic multiplexer(s) for transmission of the video signal.

System Power Requirements Seaeye Cougar-XT Compact
Input 3-Phase 380-480 VAC
ROV 18 kVA
Tooling 9 kVA

Seaeye Cougar-XT Compact Deployment and Operation

The Cougar-XT Compact is designed as a high power free-swimming ROV deployed with soft tether for depth and excursion.

A range of control cabins/workshops are available and can be adapted to suit customer-specific requirements. Exterior colours and vinyl graphics with customer logos can be added.

The ROV system can be installed into a single partitioned 20 ft cabin. The partitioned bulkhead separates the ROV piloting and control area from a 600 metre integral spooling winch. Additionally enough space is available to securely place maintenance tools and servicing spares in the cabin. Mobilisation times are drastically reduced for the single cabin uplift and setting down.

A range of different configurations and winch sizes are available to accommodate different cable lengths and applications.

An A-frame, LARS and winch with soft umbilical is a typical launch and recovery system.

An alternative telescopic crane-based LARS is available or for where deck space is limited a compact crane LARS can also be integrated within the ROV system.

Additionally a winch is available for use with the deployment vesselís A frame or crane.

All cabin and LARS can be built to Safe Area or Zone 2 ratings.
