Engineering the Low Carbon Future

As a global provider of engineered products and services, with a history of innovation and adaptation, we are committed to participating in the ongoing energy transition and working to reduce the carbon footprints of our own operations and those of our customers in the many industries we serve.

How Are We Reducing CO2 Emissions?

We are advancing technologies for use on land, underwater, and in space that help ensure worker safety and reduce environmental impacts.

*A Green Passport is an inventory of hazardous materials developed and maintained pursuant to the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships, 2009. The Convention is aimed at ensuring that ships, when being recycled after reaching the end of their operational lives, do not pose any unnecessary risks to human health, safety or the environment. A Green Passport contains an inventory of all materials used in the construction of a ship, which will be updated through the working life of the ship to maintain its accuracy. Ultimately, the passport will be delivered with the ship to the recycling yard to facilitate recycling of the ship in a safe and environmentally sound manner. The International Maritime Organization has published guidelines to assist in implementation of the Convention.

Real CO2 Savings

Our next generation, battery-operated Liberty™ E-ROV system does not require a dedicated vessel to be on standby during ROV operations. As a result, we estimate that a typical Inspection, Maintenance, and Repair (IMR) campaign in the North Sea could see up to 33 MT per day of CO2 saved by eliminating vessel usage during subsea operations with the Liberty E-ROV.

Estimated Daily CO2 Emissions By Vehicle Type While Using a Support Vessel

ROVs do not directly emit CO2, instead drawing power from the vessel used for the offshore campaign. The Liberty E-ROV draws power from its battery pack and reduces a typical IMR campaign’s dependence on support vessels to help save 33 MT per day of CO2.

2021 - Project Results

The Liberty™ E-ROV performed 55 missions and executed 9,043 dive hours in 2021, performing the work of a conventional ROV. The vehicle enabled an estimated 72.4% reduction of topside support vessel and crew support. 

E-ROV Missions Completed55
E-ROV Operational Hours9,043
Estimated Offshore Personnel Hours Eliminated26,188 (Average Four-Person Crew)
Estimated Support Vessel Hours Eliminated6,547 (72.4% of Dive Hours)
Estimated Personnel Crew Changes Eliminated156 (12-Hour Shifts / 14-Day Trips)
Estimated Support Vessel CO2 Emissions Eliminated (Tons)12,434 (Average 33T per Liberty Dive Day)

Remote Operations Enable Further CO2 Reductions

The Liberty™ E-ROV eliminates the need for ROV and vessel personnel to travel to and from marine vessels and offshore platforms, which reduces work in high-risk environments.

Along with the reductions of offshore injuries and environmental incidents, remote operations can have a direct and positive impact on the offshore energy industry’s operations, such as reducing offshore personnel hours and generating cost savings from reduced vessel hours.

How Are Remote Operations Reducing CO2 Emissions?

The logistics of bringing workers to and from offshore installations can be complex. Mobilization requires helicopter transport and vessels serving as floating hotels (floatels). By using a dedicated onshore control center that can communicate with staff stationed onshore, offshore travel and accommodations can be reduced, decreasing risk, and enabling greater collaboration and faster response times. Subject matter experts can monitor operations at several installations instead of one. Onshore Remote Operation Centers (OROCs) are staffed 24/7 to ensure operational support.

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.
