The high power compact electric work class vehicle. 

The Leopard is an exceptionally powerful electric work class vehicle with a minimal 20ft x 8ft LARS footprint. It is fitted with up to 11 thrusters to provide a forward thrust of over 500kgf, has a 200kg payload and is controlled by Saab Seaeye's iCON™ intelligent control system. 

A large open payload within the chassis allows for the installation of specially designed sliding trays equipped with survey sensors or tooling options. A wide range of tooling skids make the Leopard a versatile system capable of performing a range of work tasks in even the harshest of environments at depths of up to 3000m.


Advanced control

Advanced vehicle autopilots for heading, depth, pitch and roll, and altitude compliment Saab Seaeye's iCON™ intelligent control system that allows the system to control, self-diagnose and log data from system devices. 


An electric vehicle with eleven powerful thrusters, a large payload and the advanced control features of iCON™ give the Leopard a competitive edge over larger hydraulic vehicles.


Designed for work at depths of 2000m or 3000m and fitted with a wide range of survey sensors and heavy duty tooling options.

Leopard Overview
  •  The Leopard ROV is powered by a floor-standing high voltage, high frequency, power supply unit. Additional power supplies are available for tooling and TMS options. 

  • Pilot Control Units include touch screens running the graphical user interface (GUI) for vehicle power and control; system diagnostics including remote access for technical support; flight screen monitors that display data and video transmitted via Fibre Optic multiplexers and a CWDM; surface control units for remote control of the PSUs and a hand control unit for ROV.

  • Additional surface equipment options include TMS foot pedals for the optional TMS, tooling hand control units, video matrix switchers and recording systems. 

  • Available as a free swimming ROV or in conjunction with a Type 8 Tether Management System (TMS) or a Top Hat TMS.

  • ROV rated to up to 3000 m fitted with eight horizontal and three vertical SM9 thrusters supplied with 500 Volts DC, an electronics pod with fibre optic multiplexers and a CWDM, up to eight LED lights on four channels, cameras, a depth sensor, and a compass pod with integrated Magneto-resistive compass, accelerometers and gyros with pitch and roll outputs for vehicle auto heading, depth, pitch and roll. Auto altitude is available as an option when an altimeter is fitted as well as station keeping with a DVL fitted.

  • Standard vehicle interfaces include connections for six cameras, twelve auxiliaries including one Ethernet connection, a copper signal core for CP reference, and a Transponder Trigger.
