Light Work Class ROV Super Mohawk TMS

ELECTRIC ROV

Sub Altantic’s Super Mohawk Light Work Electric ROV has been in use all over the world for many years, providing a range of inspection and light intervention capabilities normally only available from much bigger vehicles. With a depth rating of 2000m the Super Mohawk can be used as an effective backup to Work Class Vehicles in deep water operations


The power (roughly equivalent to 17HP) of the Super Mohawk and its 85kg payload is similar to the other Light Work Electric ROVs and enables the system to a carry tooling and sensors to carry out a wide range of tasks.


The Super Mohawk is considered one of the best of the Sub-Atlantic ROVs and is a reliable and proven system offering a cost effective solution in the Offshore Energy and Oil & Gas markets. Oceana Subsea’s systems can be configured with optional skids, subject to project requirements, including:

  • Hydro-Lek manipulator skid, providing a simple and robust solution to operating inspection sensors, including CP probes, UT (Ultrasonic Thickness) Gauges, FMD (Flooded Member Detection) and other tools designed for subsea NDT.
  • Cutting Tool Skids
  • Water Jet Skids, configurable for the number of jets, pressure and nozzles
  • Brush Cleaning Skid, designed to remove marine growth

Available with tooling options for a wide range of offshore tasks, Oceana Subsea’s ROV systems deliver reliable, cost effective and flexible services in support of:

  • Survey Inspection Tasks
  • WTG / OSS Inspection & Maintenance
  • Pipeline & Cable Lay Clearance Inspection
  • Hull Inspection
  • Anchor Chain Inspection
  • UXO Target ID
  • Calm Buoy, Riser & flowline inspection
  • Cable Survey
