The Mohican ROV features a small diameter tether and high output brushless DC thrusters operating on Sub-Atlantic’s ‘Dynamic VectoringTM 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 3000 Volt, 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.
