Minimum power requirements allow for a smaller umbilical and thus less drag (and power required) on the system as a whole. These vehicles rely on accurate ship positioning to compensate for the lack of thruster power at the vehicle. To date, most ROV systems that have been built for operation in water depths over 3,000 meters have been for...
