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.
Daily Emission Savings
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.
What Could the World Do With 33 MT of CO2 Per Day?
Drive an average U.S. passenger vehicle 81,886 miles
Charge 4,208,563 smartphones
Provide 4 homes with energy for one year
Save the CO2 equivalent of consuming 76 barrels of oil

2020 - Project Results
The Liberty™ E-ROV performed 12 missions and executed 3,824 dive hours in 2020, performing the work of a conventional ROV. The vehicle enabled an estimated 72% reduction of topside support vessel and crew support.
|E-ROV Missions Completed||12|
|E-ROV Operational Hours||3,824|
|Estimated Offshore Personnel Hours Eliminated||11,076 (Average Four-Person Crew)|
|Estimated Support Vessel Hours Eliminated||2,769 (72.4% of Dive Hours)|
|Estimated Personnel Crew Changes Eliminated||66 (12-Hour Shifts / 14-Day Trips)|
|Estimated Support Vessel CO2 Emissions Eliminated (Tons)||5,258 (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.

The forward-looking statements include, without limitation, statements about Oceaneering’s: participation in the ongoing energy transition and future reductions of carbon footprints; and estimates of carbon dioxide and other savings through the use of specified technologies.
We have based these forward-looking statements on our current expectations and assumptions about future events. While our management considers these expectations and assumptions to be reasonable, they may differ significantly from expectations and assumptions that would be developed by independent third parties and are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties that could cause actual results to differ materially from those indicated by the forward-looking statements.
Among the factors that could cause actual results to differ materially include: general economic and business conditions and industry trends; changes in, or our ability to comply with, various laws and governmental regulations, including those relating to the environment; the effects of competition; the continued availability of qualified personnel; operating risks normally incident to offshore exploration, development and production operations; hurricanes and other adverse weather and sea conditions; and rapid technological changes.
