You are visiting: Saab Seaeye


The high power compact electric work class vehicle.

Data Sheet

The Leopard is an exceptionally powerful electric work class vehicle with a minimal 20ft x 8ft LARS footprint. It is fitted with 11 thrusters to provide a forward thrust of over 500kgf, has a 240kg payload and is controlled by Saab Seaeye's iCON™ intelligent control system.

A large open payload within the chassis allows flexible reconfiguration of the vehicle by installing combinations of specially designed tooling, survey and navigation sleds. A 1000kg through-frame lift and 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, altitude, pitch and roll, and Station Keeping 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.

  • The ROV can be fitted with Schilling Orion 7P + 4R Manipulators together with a compact Integrated Hydraulic Power Unit (IHPU) based circuit including a valve pack with seven bi-directional rate valves. Additionally, for typical intervention and work class tasks such as cutting, grinding, water jetting and dredging an auxiliary 3000VAC high power hydraulic work pack can be fitted.

  • Surface control hardware includes 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, and a hand control unit for the ROV.

  • Additional surface equipment options include TMS foot pedals for the optional TMS, tooling hand control units, video equipment and recording/eventing 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 up to 3000m 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 ten 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. Station Keeping with nudge controls is available as an option when a compatible DVL and/or INS is fitted.

  • Standard vehicle interfaces include connections for up to six composite cameras, fifteen auxiliaries including six Gb Ethernet channels on a dedicated 2.5G link, high power 24VDC and 48VDC interfaces supporting the latest advanced survey and imaging equipment, a copper signal core for CP reference, and trigger interfaces supporting Responder Transponders, PPS and timing of Acoustic devices. A spare fibre and CWDM fibre wavelengths provide options for survey multiplexer bottles and HD/UHD/4K video cameras.

  • 110VAC equipment is supported through an optional subsea 350W output pure sine wave Inverter pod powered from a dedicated 24VDC interface on the ROV Epod, or a 2kW output Transformer pod powered from a surface 3kV 50/60Hz Tooling Supply.

  • The surface video architecture is based on modern digital HD/UHD broadcast standards and includes a 20x20 SD/HD/UHD video switcher and 8x8 HDMI switcher (with control through the iCON touchscreen GUI) and a single channel HD Pilot Video Overlay.

  • Video options include up to six Subsea Composite Video interfaces, two HD-SDI Video over Coax interfaces, surface decoders for IP Video cameras, HD/4K monitors and display splitters, and SD/HD/4K digital video recorders and overlays.

  • An optional Onshore Piloting remote operator station enables robust over-the-horizon control and piloting of the ROV and TMS.
