Riverway Group and Offshore Data Center Join Forces to Develop Gas-Powered Offshore Data Centers
Riverway Group, LLC, a Houston-based company, and Offshore Data Center, LLC, have announced a collaboration to develop offshore platforms designed to convert stranded and undervalued natural gas resources into electricity for data centers located near offshore gas supplies. The initiative aims to provide oil and gas producers with new opportunities to monetize resources that may be uneconomical to develop through conventional production and transportation methods.
The collaboration brings together Offshore Data Center’s industry partnerships and offshore platform concepts with Riverway Group’s automated welding technologies and advanced fabrication capabilities. The companies intend to develop offshore structures that can accommodate energy-intensive computing facilities while taking advantage of locally available natural gas and deep-ocean cooling resources.
By locating computing infrastructure close to offshore gas production, the proposed platforms could reduce the need to transport gas to shore and deliver electricity through conventional transmission networks. The approach is intended to address several challenges associated with offshore energy development, including the cost of connecting remote gas resources to existing markets, the growing demand for computing capacity, and the substantial energy requirements of data center cooling systems.
Turning Stranded Offshore Gas Into a Valuable Energy Resource
Offshore natural gas resources can remain undeveloped when the cost of transporting production to shore exceeds the potential commercial returns. In some cases, producers may reinject gas into reservoirs rather than bring it to market because suitable pipelines and other transportation infrastructure are unavailable or too expensive to construct.
The Riverway Group and Offshore Data Center collaboration seeks to address this challenge by bringing electricity-consuming facilities directly to the source of the fuel. Instead of transporting natural gas over long distances, the proposed platforms would use offshore gas to generate power for data center operations at the production location.
This model could provide offshore operators with an alternative route to commercialize resources that otherwise might remain underutilized. It could also create new opportunities for integrating natural gas production with digital infrastructure, particularly as demand for computing resources continues to expand.
Data centers require dependable electricity to support servers, networking equipment, storage systems and other essential infrastructure. By developing platforms around available offshore gas supplies, the companies aim to establish an integrated arrangement in which fuel production and computing operations are located together.
The concept is intended to reduce dependence on certain elements of conventional energy transportation infrastructure. However, the commercial viability of individual projects will depend on factors such as gas availability, offshore operating conditions, power-generation requirements, construction costs, connectivity and applicable regulatory approvals.
Combining Advanced Hull Designs With U.S. Manufacturing Capabilities
A central component of the partnership is the combination of Offshore Data Center’s relationships with technology and offshore engineering partners and Riverway Group’s fabrication expertise.
The collaboration includes patented and proprietary semi-submersible hull designs associated with HORTON DO BRASIL TECNOLOGIA OFFSHORE LTDA. These designs are intended to support offshore facilities that require substantial load-bearing capacity while maintaining stability in marine environments.
According to the companies, the proposed hulls can weigh up to 50% less than traditional designs while delivering improved stability. The reduced structural weight is intended to help lower fabrication and construction costs, potentially making production on the U.S. Gulf Coast more competitive with shipbuilding and offshore fabrication centers in South Korea, China and Singapore.
Riverway’s automated welding and advanced fabrication methods are expected to contribute to the construction process. By incorporating automation into manufacturing operations, the companies aim to improve fabrication efficiency and support the production of specialized offshore structures.
Developing these platforms in the United States could also create opportunities for domestic shipyards, offshore engineering companies, equipment suppliers and other industrial businesses. The partnership’s manufacturing strategy is intended to strengthen local capabilities for producing complex marine structures designed for emerging energy and digital infrastructure applications.
The use of semi-submersible platforms is particularly relevant to offshore projects that require a stable base for large equipment and facilities. Their design must accommodate marine conditions while supporting the weight and operating demands of the infrastructure installed above the waterline.
Supporting High-Demand Data Center Infrastructure
The offshore platforms are being engineered to accommodate significant topside loads, allowing them to support a range of industrial applications. Planned potential uses include data centers, ammonia or methanol production facilities, and conventional offshore oil and gas production installations.
For data center applications, the platforms would provide the structural foundation for computing equipment and associated electrical and mechanical systems. These installations require careful integration of power generation, cooling equipment, communications infrastructure, safety systems and operational support facilities.
The ability to accommodate different types of topside infrastructure could give the platforms flexibility for use in projects with varying commercial and industrial requirements.
In addition to computing facilities, the proposed structures could support chemical production units that use offshore natural gas as a feedstock or energy source. Ammonia and methanol production, for example, can require substantial energy and specialized process equipment. Offshore facilities combining these activities with local gas resources could offer another approach to developing remote energy supplies, subject to project-specific engineering and economic assessments.
Conventional production equipment is also among the potential applications identified by the companies. This broad design scope could allow the underlying platform technology to serve multiple offshore industries rather than being limited to a single type of installation.
The partners have not specified project-by-project deployment schedules, facility capacities or final construction budgets in the announcement. Further engineering, commercial planning and implementation work would be needed to determine the configuration and scale of individual developments.
Deep-Ocean Cooling Designed to Reduce Energy Consumption
Cooling represents another important element of the proposed offshore data center concept.Data centers generate heat as servers and other computing equipment operate continuously. Maintaining appropriate operating temperatures requires cooling systems that can consume a substantial share of a facility’s electricity.
The companies state that cooling can account for as much as 40% of a data center’s energy use, depending on its design and operating conditions. Reducing this demand could improve overall energy efficiency and help make computing facilities more economical to operate.
To address this requirement, the proposed offshore platforms incorporate patented and proprietary closed-loop deep-ocean cooling systems. These systems are intended to use the naturally cold temperatures of deep-ocean water to remove heat from facility cooling circuits.
In a closed-loop arrangement, the cooling fluid circulating through the data center’s equipment can remain separated from the seawater used to transfer heat. A heat-exchange system can move thermal energy from the facility’s cooling circuit to the colder water, reducing the need for conventional mechanical cooling.
The availability of deep, cold seawater could provide an advantage for appropriately located offshore facilities. By lowering the temperature of the cooling medium, the system may reduce the work required from conventional cooling equipment and potentially improve the efficiency of associated power-generation operations.
The practical benefits would depend on factors including water depth, local ocean temperatures, cooling demand, heat-exchanger performance, system pumping requirements, maintenance needs and environmental considerations.
The companies’ approach combines power generation from offshore natural gas with a cooling strategy designed around the marine environment. Together, these elements are intended to address two major operating costs for data centers: electricity supply and heat management.
Eliminating the Need for Certain Shore-Based Connections
A major objective of the partnership is to reduce the infrastructure required to bring stranded offshore gas into commercial use.
Traditional development of remote gas resources may require pipelines connecting offshore production facilities with onshore processing and distribution networks. Once gas reaches shore, electricity-intensive customers may also depend on transmission infrastructure to obtain the power they need.
The offshore data center concept seeks to avoid the need for a pipeline to shore and a shore-based transmission connection dedicated to supplying the offshore facility. Instead, natural gas would be used to generate electricity near the data center.
Art J. Schroeder, Jr., CEO of Offshore Data Center, said that a significant amount of offshore gas remains undeveloped or is reinjected because bringing it to market is not economically practical under existing arrangements.
Schroeder explained that placing data centers close to the gas resource could remove the need for the conventional pipeline and transmission connections while substantially reducing cooling expenses. He also highlighted Riverway’s role in enabling the companies to pursue construction of the platforms in the United States.
The approach could be especially relevant where offshore gas resources are available but pipeline access is limited. However, eliminating some shore-based connections does not remove the need for other critical infrastructure, including communications links, maintenance access, safety systems, fuel-processing equipment and reliable power-generation systems.
Offshore data centers would also need to address operational challenges associated with remote locations, including equipment servicing, workforce access, severe weather, marine corrosion and continuity of digital services.
Strengthening U.S. Maritime Manufacturing and Energy Development
Beyond the development of offshore computing facilities, the collaboration is intended to support domestic manufacturing and energy-sector activity.
The companies expect the initiative to contribute to U.S. maritime manufacturing by creating opportunities to build specialized offshore platforms on the Gulf Coast. A domestic fabrication program could generate work for welding specialists, structural engineers, equipment manufacturers, offshore contractors and supporting supply-chain businesses.
The development of new offshore infrastructure may also encourage investment in manufacturing processes and engineering capabilities that can be applied to future marine energy projects.
For the energy sector, the initiative offers a potential additional use for natural gas resources that are difficult to commercialize through traditional routes. Integrating gas production with power generation and computing operations could provide producers with an alternative customer base while creating a direct relationship between energy resources and electricity-intensive industries.
The companies also anticipate benefits for domestic computing capacity. As demand for data processing and other digital services grows, additional infrastructure capable of supplying reliable power could help support future expansion.
Potential economic benefits identified by the partners include employment opportunities and tax revenue associated with manufacturing, construction and related business activity. The extent of these benefits will depend on whether the projects advance from development and design into commercial construction and operation.
A New Approach to Offshore Energy and Digital Infrastructure
The Riverway Group and Offshore Data Center partnership reflects an effort to connect offshore natural gas development with the growing energy needs of data centers.
Rather than treating gas production, electricity generation, cooling and computing infrastructure as separate activities, the proposed model brings them together within a single offshore development concept. Its central premise is that locating a data center near an otherwise difficult-to-market gas resource could reduce certain transportation costs while using the marine environment to support thermal management.
The collaboration combines semi-submersible platform engineering, automated fabrication, local gas-fired power generation and closed-loop deep-ocean cooling. If successfully developed and deployed, the concept could offer a different model for selected offshore locations where gas resources, marine conditions and computing requirements align.
At the same time, the approach will require careful evaluation of engineering performance, operating reliability, environmental impacts, safety requirements and project economics. Offshore facilities must be designed to withstand challenging marine conditions, and data centers must maintain dependable power, cooling and communications to support continuous operations.
The partners’ announcement establishes a framework for collaboration but does not, by itself, confirm that a specific platform has been constructed or placed into commercial service.
As the initiative progresses, its success will depend on the companies’ ability to translate the proposed engineering and manufacturing advantages into practical offshore installations. The development could ultimately create a new application for underutilized natural gas resources while opening additional opportunities for U.S. maritime manufacturing and offshore industrial infrastructure.
About Offshore Data Center, LLC
Offshore Data Center, LLC develops offshore data centers powered by natural gas at the source. The company targets gas that is stranded, uneconomic under conventional development models, or undervalued — including gas reinjected beyond what reservoir pressure maintenance requires. Its concepts range from facilities of up to 1 gigawatt for large-scale AI training to smaller, lower-cost, faster-to-deploy configurations for edge and inference computing.
