Transocean — Business Overview

What does Transocean do?

Transocean is an offshore contract driller — it rents out high-tech floating rigs and the crews to operate them so oil and gas companies can drill wells in deep water. As of early 2026, the company owned or operated 27 mobile offshore drilling units: 20 ultra-deepwater drillships (ship-shaped vessels that drill in water depths of 4,500 feet or more) and 7 harsh environment semisubmersibles (partially submerged platforms built for rough seas, such as the Norwegian North Sea). The company operates as a single business segment — contract drilling — so there are no separate divisions to compare.

Transocean is in the process of a major merger. In February 2026, it announced a deal to acquire Valaris, a competitor, in an all-stock transaction. If completed, this would meaningfully expand the combined fleet and the company's scale in the offshore drilling market.

How does Transocean make money?

Transocean earns revenue by charging customers a daily fee — called a dayrate — for use of its rigs, equipment, and crew. Customers are oil and gas companies (integrated majors, independents, and national oil companies) that need offshore rigs to drill exploration or production wells. The dayrate is higher when the rig is operating efficiently and lower — or zero — during downtime caused by equipment issues, weather, or regulatory delays. Contracts cover either a single well, a group of wells, or a set time period.

The company's contract backlog provides some revenue visibility. At December 31, 2025, Transocean's contract backlog (the total future revenue locked in under existing contracts) stood at $6.29 billion, down 28% from $8.74 billion a year earlier and down 32% from $9.25 billion at year-end 2023. The declining backlog signals that fewer new contracts have been signed recently than contracts have been completed or cancelled.

What market does Transocean operate in?

Transocean operates in the global offshore contract drilling market, which is highly cyclical and closely tied to oil and gas prices. When energy prices are high, oil companies invest more in exploration and production, which drives demand for rigs and pushes dayrates up. When prices fall, customers cut spending, contracts dry up, and rigs get stacked (taken out of service). The company focuses on two technically demanding niches: ultra-deepwater (water depths of 4,500 to 12,000 feet) and harsh environment drilling (cold, rough-sea regions like the Norwegian continental shelf and sub-Arctic waters).

Secular forces create a mixed picture for this industry. The long-term energy transition away from fossil fuels poses a structural headwind for offshore drilling demand over time. However, in the near term, deepwater resources remain important to global supply, and offshore fields — particularly in regions like Brazil, West Africa, and the U.S. Gulf — continue to attract investment from major oil companies. High-specification rigs capable of drilling in ultra-deep water tend to hold up better during downturns than older, simpler equipment.

Who are Transocean's main competitors?

The offshore drilling industry is relatively consolidated at the high end, with a handful of large players competing for the same contracts from a limited pool of customers. Transocean positions itself at the premium end of the market, targeting technically demanding drilling jobs that require the most capable rigs. Its pending merger with Valaris — itself a major offshore driller — would further consolidate the industry. Other significant competitors include Noble Corporation, Seadrill, and Diamond Offshore.

Transocean's claimed competitive advantages center on fleet quality, technology, and operating track record. The company highlights milestones such as the first dynamically positioned drillship, the first dual-activity drillship, and world-record water depths drilled. Eighteen of its drillships feature dual-activity technology (two simultaneous drilling stations that cut the time needed to complete a well), and two of its newest ships carry industry-leading 1,700-ton hoisting systems with 20,000-psi blowout preventers — the highest well-control pressure rating available. These capabilities are expensive for competitors to replicate and are increasingly demanded by customers drilling in the most complex environments.

Where does Transocean operate?

Transocean's fleet is globally dispersed, with meaningful concentrations in the U.S. Gulf, Brazil, and Norway. As of February 2026, its 27 rigs were located across nine countries and regions:

Brazil is a particularly important market, with six rigs operating there — many under contracts tied to Petrobras, Brazil's national oil company. Norway represents a key region for the harsh environment semisubmersible fleet, given the North Sea's year-round difficult conditions. Because the rigs are floating vessels, they can be relocated between regions in response to market demand, so the geographic mix can shift over time. The company's workforce of approximately 5,600 people spans 20 countries across six continents, with 38% in North America, 26% in South America, and 23% in Europe.
