The small vehicle with real work capabilities. 

Data Sheet

The Cougar-XT is a highly flexible, small, yet extremely powerful vehicle depth rated to 2000m. Six 500 Volts DC thrusters provide precise handling and control in strong current environments.

Designed to accommodate heavy duty tooling via a system of quick-change tool skids, the Cougar-XT is ideal for survey work, IRM, drill support, light construction projects and salvage support operations. 

The surface equipment for the Cougar-XT can be provided as free-standing units or integrated into a control cabin.

Outstanding performance

Six thrusters and a large payload provide a stable platform for working in strong currents or deep water.


A variety of tooling options can deliver results for survey, IRM, or salvage projects. 

Industry proven

Designed for work in extreme environments, the Cougar-XT is a powerful vehicle recognised for its capability as a compact work vehicle.

Cougar-XT Overview
  • Surface Power Supply Unit and Surface Control Unit supplied as free standing units or fitted inside an air conditioned control container. An additional tooling power supply option is available.

  • Surface Equipment includes Hand Control Unit, keyboard and two colour monitors. An additional hand control unit is available for systems fitted with a manipulator skid.

  • Cabin Junction Box for connections between the surface and subsea. Includes Fibre Optic MUX console with two live video, four serial and one Ethernet connection used for data and video transmission. Additional MUX options are available.
