Product catalog summary

Overview: The Super Mohawk ROV system is a versatile remotely operated vehicle designed for a variety of tasks typically performed by work-class vehicles. It features a robust open-frame design, ample space for equipment, and a high payload capacity, making it suitable for observation, survey, pipelay support, light to medium work, and non-destructive testing (NDT) inspections. The system is rated for depths of 2000 meters (6560 feet) with options for deeper operations.

Key Specifications:

Depth Rating: 2000 meters (6560 feet) standard, with deeper options available.
Payload Capacity: 60 kg (132 lb).
Dimensions: Height - 850 mm, Length - 1400 mm, Width - 900 mm.
Mass in Air: 290 kg (639 lb).
Thrust: Forward - 110 kgf, Reverse - 77 kgf, Lateral - 73 kgf, Vertical - 45 kgf.
Max Velocity: Forward - 1.5 m/s, Reverse - 1.0 m/s, Lateral - 0.75 m/s, Vertical - 0.75 m/s.
Power Requirements: 440 Vac 3 ph 50/60 Hz 15 kVA.

Surface Equipment: The surface equipment 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, with options for installation in an ISO control cabin or a 19-inch rack mount flight case.

Tether and Umbilical: The system uses a 25.5 mm diameter tether and a common umbilical suitable for all open-frame vehicles, enhancing spares and interchangeability.

Sensors and Equipment: The ROV supports various sensors and equipment, including cameras, sonar, oceanographic sensors, manipulators, tool skids, and torque tools.

Tether Management System (TMS): Available in three sizes, the TMS is known for its ruggedness and reliability, with a capacity of 250 meters of tether.

Launch and Recovery Systems: Various systems are available to meet different depth requirements and formats, such as A-frame or jib crane.

Frame and Buoyancy: The frame is made of high-impact resistant polypropylene with an aluminum alloy central load frame. Buoyancy is provided by a single module with closed-cell microspheres.

Thrusters: The ROV is propelled by six Sub-Atlantic CTE02 thrusters, providing high thrust and speed in a vectored configuration.

Electronic Pod and Telemetry: The system includes a fiber-optic telemetry system with multiple video and data channels, housed in aluminum alloy pods rated to 2000 meters.

Lighting and Camera Facilities: Equipped with three 250-Watt halogen lamps and a pan & tilt unit for cameras, providing three simultaneous video channels.

Note: Specifications are illustrative for marketing purposes and may vary due to product improvements. Specific interface and performance details should be confirmed at the time of order placement.
