Liberty™ E-ROV

Intervene faster, keep production online more effectively, and reduce your carbon footprint

Increasing Efficiencies


Oceaneering's Liberty E-ROV is a self-contained, battery-powered, work-class vehicle that allows you to perform routine tasks with fewer deployments. It can carry out inspection, maintenance, and repair (IMR), commissioning, and underwater intervention activities.

It is an all-in-one deployable and recoverable system with a cage-mounted battery pack and tether management system, and communications buoy, which hosts an antenna mast to improve signal reception and battery power to support communications transfer. Liberty's batteries provide 500 kWh power.

Reduce Your Carbon Footprint up to 90%

The Liberty E-ROV system is environmentally friendly, enabling a reduction in carbon footprints—up to 90%.

When quantifying the yearly CO2 emissions the Liberty system eliminates when compared to a vessel-based ROV spread, the numbers are significant. An estimate shows that the emissions drop from 51,000 lbs a year to 5,000 when the resident Liberty ROV is used.

The system is a semi-resident and does not require a vessel to be deployed along with it. Vessels can be freed up to either perform other tasks while the Liberty E-ROV performs its own subsea, such as inspection, valve operation, torque tool operation, and manipulator-related activities.

Backed by 24/7 Onshore Support

Oceaneering's Onshore Remote Operations Centers (OROC) can support and operate the Liberty E-ROV from locations located strategically around the world.

OROC is able to accomplish this with communication provided via high bandwidth low latency 4G LTE and satellite communication from the Liberty E-ROV system's buoy. The combination of these technologies makes Liberty E-ROV a very cost-effective subsea tool.

Subsea Resident ROV Eliminates Vessel Requirements and Provides Substantial Cost Savings for Client

LibertyTM E-ROV deployed as stand-by, emergency support during well workover activities

In late 2019, a major operator was completing well workover activities on a template offshore Norway using a semi submersible drilling rig. The operations included pulling a high pressure cap and there was potential for the release of pressure and a subsequent gas leak.

Company page Since our founding in the early 1960s, Oceaneering has expanded and grown globally to service several industries such as the offshore energy industry, defense, entertainment, material handling, aerospace, science, and renewable energy industries. In 1964, Mike Hughes and Johnny Johnson formed a Gulf of Mexico diving company called World Wide Divers. The company grew in response to increasing demand for their services and in 1969 merged with two other diving companies to form Oceaneering International, Inc. To solve the toughest challenges, we do things differently, creatively, and smarter. As your trusted partner, our unmatched experience and truly innovative portfolio of technologies and solutions give us the flexibility to adapt and evolve, regardless of market conditions. Our mission is to solve the unsolvable. We thrive by creating industry-changing technically creative solutions for the most complex operational challenges under water, on land, and in space. Our five core values establish a common culture and demonstrate what is most important for us as a company. Since the beginning, the company has transformed from a small regional diving company into a global provider of engineered products and services. Today, we develop products and services for use throughout the lifecycle of an offshore oilfield, from drilling to decommissioning. We operate the world's premier fleet of work class ROVs. Additionally, we are a leader in offshore oilfield maintenance services, umbilicals, subsea hardware, and tooling. We also serve the aerospace, defense, and theme park industries. Underpinning everything we do, safety is not only the foundation of our core values, but it is vital to our unmatched performance record and company culture. The industries we serve are as diverse as they are complex. Whether we are engineering deepwater umbilicals or developing robotics for aerospace applications, the safety and health of our employees, vendors, and customers is an integral part of our day-to-day business. If we are working, then our responsibility is to be working safely. Since our inception in 1964, we have placed a high value on employee safety—from diving services and subsea inspection to vessel-based installation operations. We have and will continue to evolve not only our health, safety, and environmental (HSE) processes, but those of the industries in which we work. Although we have been fatality-free since 1999, our HSE journey goes beyond statistics. As our portfolio of services has grown, we have continued to prioritize and advance our approach to HSE.
