Product catalog summary
Overview: The Mohican Inspection ROV System by Sub-Atlantic is designed for high-quality video inspections and platform inspections. It features a small diameter tether, high output brushless DC thrusters, and a fibre-optic telemetry system. The system is suitable for long tunnel inspections and deep live-boating operations.
Specifications: The ROV has a depth rating of 2000 meters (6560 feet) with a standard payload of 35 kg (77 lbs). It measures 1150 mm in length, 800 mm in height, and 770 mm in width, with a mass of 290 kg in air. The power system operates at 3000 Volt, 400 Hz, and the ROV can achieve a maximum thrust of 110 kgf in forward, reverse, and lateral directions.
Propulsion and Thrusters: The Mohican uses six brushless DC thrusters with Sub-Atlantic's StatorshieldTM Technology and Dynamic VectoringTM. This configuration provides high thrust and reliability, with the ability to adjust the thruster vector angle remotely.
Surface Equipment: The system includes a Surface Control Unit (SCU), Transformer Power Unit (TPU), and Hand Control Unit (HCU). These components are compact and designed for operation in small control spaces. The SCU features two 15” color monitors, light dimmers, and a video overlay system.
Tether and Umbilical: The standard tether has a diameter of 16.5 mm, while the main lift umbilical is 25.5 mm in diameter. The system supports live boating and TMS operations.
Additional Features: The Mohican ROV supports various sensors and equipment, including cameras, sonar, and manipulators. It can be fitted with standard and custom tooling packages and underslung skids.
Launch & Recovery Systems: Sub-Atlantic offers various launch and recovery systems, including A-frame and jib crane formats, to meet different depth requirements.
Note: Specifications are illustrative for marketing purposes and may vary due to product improvements.

MOHICAN Inspection Class ROV Data Sheet-1

MOHICAN Inspection ROV System system incorporates an enhanced propulsion system allowing it to continue working in high current conditions when other systems have to return to surface, providing a customer benefit of reduced ssel time and costs. Ultra-High Thrust Greater Than 100 kgf / 220 Ibf Both Axial and Lateral Six Brushless DCThrusters with Sub- Atlantic's Statorshield™ Technology and Dynamic Vectoring 3000 Volt, 400 Hz Power System Long, Small Diameter, Low Drag Tether 2,000 Metre / 6,500 Feet Standard Rating 35 kg / 77 lbs Standard Payload (Options) Multiple Video Channels Deep Live Boat,Tunnel orTMS Operation Manipulator Options Integral High Pressure Cleaning System Various Skid Options The Mohican ROV features a small diameter tether and high output brushless DC thrusters operating on Sub- Atlantic's 'DynamicVectoring™ system. The Mohican comes with three or six simultaneous video channels transmitted through a fibre-optic telemetry system for sharp, high quality video inspections. The ROV is also equipped with additional power sources for attachment of manipulator and tools such as our high pressure jetting and cleaning skid used in platform inspections. Mohican uses a 3000Volt, 400 Hz power transmission system from surface to ROV resulting in a small tether; main lift cable and launch & recovery system. This transmission system makes Mohican particularly suited for long tunnel inspections and deep live-boating operations.
