A new joint venture with co-headquarters in Houston will explore opportunities in the market for subsea systems that tap into offshore energy reserves.

The business, called OneSubsea, is a joint venture of Houston-based energy technology company SLB (Schlumberger), Norwegian energy engineering company Aker Solutions, and Luxembourg-based energy engineering company Subsea7. SLB holds a 70 percent stake in OneSubsea, with Aker’s share at 20 percent and Subsea7’s share at 10 percent.

The financial foundation of the joint venture is a combination of $700.5 million in stock, cash, and a promissory note. In addition, SLB and Aker folded their subsea businesses into the joint venture, which was announced in 2022.

“As demand grows for cost-effective, efficient, and sustainable energy,” the joint venture says, “a large portion of the corresponding supply increase will come from offshore developments resulting in strong deepwater activity … and the need for innovative subsea solutions.”

OneSubsea is based in Oslo, Norway, and Houston.

As Aker explains, a subsea system “provides a way to produce hydrocarbons from areas not economically or easily developed by the use of an offshore platform.” The system’s ocean-floor components are connected to subsea pipelines, riser systems, and other equipment.

Hydrocarbons are the key components of oil and natural gas.

“The offshore market is demonstrating a sustained resurgence as operators across the world look to accelerate development cycle times and increase the productivity of their offshore assets,” says Olivier Le Peuch, CEO of SLB.

Mads Hjelmeland is the newly appointed CEO of OneSubsea, which employs about 11,000 people around the world.

“OneSubsea’s extensive technology portfolio and engineering expertise enable us to address future market trends and needs at a unique scale. In doing so, we aim to fulfil our purpose of expanding the frontiers of subsea to drive a sustainable energy future,” says Hjelmeland, who is based in Houston.

Hjelmeland’s tenure with the previous iteration of OneSubsea began in 2014. That’s a year after SLB and Cameron, a supplier of equipment, systems and services for the oil and gas industry, formed a joint venture known as OneSubsea to serve the subsea oil and gas market. SLB owned a 40 percent stake in OneSubsea, and Cameron owned a 60 percent stake.

To establish OneSubsea, Cameron contributed its subsea business, and SLB pitched in a $600 million payment to Cameron along with several business units.

In 2016, SLB acquired Cameron in a cash-and-stock deal initially valued at $14.8 billion. OneSubsea then became a subsidiary of SLB, and that subsidiary is now part of the newly reconfigured OneSubsea.

Data centers are proving to be a massive economic force in Texas.

For instance, a new report from clean energy company Bloom Energy predicts Texas will see a 142 percent increase in its market share for data centers from 2025 to 2028. That would be the highest increase of any state.

Bloom Energy expects Texas to exceed 40 gigawatts of data-center capacity by 2028, representing a nearly 30 percent share of the U.S. market. A typical AI data center consumes 1 to 2 gigawatts of energy.

“Data center and AI factory developers can’t afford delays,” Natalie Sunderland, Bloom Energy’s chief marketing officer, said in the report. “Our analysis and survey results show that they’re moving into power‑advantaged regions where capacity can be secured faster — and increasingly designing campuses to operate independently of the grid.”

“The surge in AI demand creates a clear opportunity for states that can adapt to support large-scale AI deployments at speed,” Sunderland adds.

Further evidence of the data center explosion in Texas comes from ConstructConnect, a provider of data and software for contractors and manufacturers. ConstructConnect reported that in the 12-month span through November 2025, data-center construction starts in Texas accounted for $11 billion in spending. At $12.5 billion, only Louisiana surpassed the Texas total.

Capital expenses for U.S. data centers were expected to surpass $425 billion last year, according to ratings agency S&P Global.

ConstructConnect also reports that Texas is among five states collectively grabbing 80 percent of potential data center construction starts. Currently, Texas hosts around 400 data centers, with close to 60 of them in the Houston market.

A large pool of data-center construction spending in Texas is flowing from Google, which announced in November that it would earmark $40 billion for new AI data centers in the state.

“Texas leads in AI and tech innovation,” Gov. Greg Abbott proclaimed when the Google investment was unveiled.

Other studies and reports lay out just how much data centers are influencing economic growth in the Lone Star State:

  • A study by Texas Royalty Brokers indicates Texas leads the U.S. with 17 clusters of AI data centers. The study measured the density of AI data centers by counting the number of graphics processing units (GPUs) installed in those clusters. GPUs are specialized chips built to run AI models and perform complex calculations.
  • Citing data from construction consulting company FMI, The Wall Street Journal reported that spending on construction of data centers is expected to rise 23 percent in 2026 compared with last year. Much of that construction spending will happen in Texas. In the 12 months through November 2025, the average data center cost $597 million, according to ConstructConnect.
  • Data published in 2025 by commercial real estate services company Cushman & Wakefield shows three Texas markets — Austin, Dallas and San Antonio — boast the lowest construction costs for data centers among the 19 U.S. markets that were analyzed. The mid-range of costs in that trio of markets is roughly $10.65 million per megawatt. Houston isn’t included in the data.

Although Houston isn’t cited in the Cushman & Wakefield data, it nonetheless is playing a major role in the data-center boom. Houston-area energy giants Chevron and ExxonMobil are chasing opportunities to supply natural gas as a power source for data centers, for example.

“As Houston rapidly evolves into a hub for AI, cloud computing, and data infrastructure, the city is experiencing a surge in data-center investments driven by its unique position at the intersection of energy, technology, and innovation,” says the Greater Houston Partnership.
