Valaris Brand Guidelines: Ensco, Rowan, a 2021 Restructuring & a Pending Transocean Deal

A six-rig Texas driller grows up.

Valaris is a young name on an older company. Its main line of descent, Wikipedia says, runs back to 1975, when, after the 1973 oil crisis, John R. Blocker bought Choya Energy, a six-rig contract drilling company in Alice, Texas, and renamed it Blocker Energy. The company went public in 1980 and borrowed heavily to expand to 54 rigs, then restructured when the oil price fell in late 1982, handing most of its equity to its banks; by 1983 it was running only six rigs.

Richard Rainwater’s BEC Ventures invested in 1986 and brought in Carl F. Thorne to run the business, and in 1987 it took the name Energy Service Company, shortened to Ensco. In 1990 Ensco acquired Penrod, adding 19 rigs, and over the next two decades it became a mainly offshore driller. In 2010, Wikipedia says, it moved its headquarters to London and became a UK-registered company; it acquired Pride International in 2011 and Atwood Oceanics in 2017, after which Wikipedia describes it as the largest owner of jackup fleets worldwide.

The other half of Valaris was Rowan Companies, another offshore driller. On 11 April 2019, OE Digital reported, Ensco and Rowan completed their merger after shareholder approval and sanction by the UK court, creating Ensco Rowan, headquartered in London with a significant presence in Houston and traded in New York. Rowan shareholders received about 45 percent of the combined company. OE Digital called it the world’s largest offshore driller by fleet size, with 16 drillships, 12 semi-submersibles and 54 jackups listed on its website. Later in 2019 the company renamed itself Valaris plc.

Chapter 11 and a Bermuda parent.

The new name arrived just before a hard downturn. In August 2020, in what its chief executive later described as a downturn caused by the COVID-19 pandemic, Valaris filed for bankruptcy under Chapter 11 in a prearranged process. The United States Bankruptcy Court for the Southern District of Texas confirmed its plan of reorganization on 3 March 2021, and on 30 April 2021, OE Digital reported on 3 May 2021, the company completed its financial restructuring and emerged from Chapter 11. The court process took about eight months from filing to emergence.

The restructuring changed the company’s legal shape. The new parent is Valaris Limited, incorporated in Bermuda, and Wikipedia places its headquarters in Houston, Texas, rather than London. The English company Valaris plc, created by the 2019 merger, was the parent that entered Chapter 11; Valaris Limited is the parent that came out of it.

Valaris works across the main offshore rig types. Wikipedia says that in February 2025 it owned 52 rigs: 36 jackups, 11 drillships and five semi-submersibles. Its rig names follow simple numbered series, such as Valaris DS-18 for a drillship and Valaris MS-1 for a semi-submersible.

Its 2026 contract news was mixed in the usual way of the trade. Baird Maritime reported on 5 November 2026 that the company had sold the semi-submersible Valaris MS-1 for recycling, sold the long-stacked jackup Valaris 111 to a buyer planning to convert it into a mobile offshore production unit, and kept three drillships stacked in Spain, while saying that all ten of its active drillships were under contract. New work included an exploration contract off Suriname for Valaris DS-18 and a platform drilling contract for BP in the US Gulf of Mexico starting in January 2027.

How drilling contractors present themselves.

Drilling contractors sell time on machines that most of their customers’ shareholders will never see, so their public image leans heavily on photographs of the machines themselves. Offshore companies favour the long view: a drillship or a semi-submersible standing alone on open water, its derrick the tallest thing for miles, or a jackup rig on its three legs with the sun going down behind it. Land drillers tend to show a single rig on flat, open ground, with a line of trucks and a wide sky.

People appear too, and usually in working clothes. Derrick crews in coveralls and hard hats, gloved hands on pipe, and teams on the rig floor are the standard human images of the trade. Many contractors also run named safety campaigns aimed at their own crews, with slogans, posters and stickers that become part of the visual language of a rig as much as of the company.

Much of a driller’s graphic output is financial and technical rather than promotional. Listed contractors publish fleet status reports, which list each rig with its type, location, customer and contract dates, and investor presentations full of rig diagrams, maps and backlog charts. These documents are read closely by analysts and customers, and their layout is often plainer and more consistent than the company’s marketing.

Names carry a lot of the weight. The industry has been shaped by mergers, so many contractors are the sum of older firms, and rigs often keep a predecessor’s name or a numbered series long after the company that built them has gone. A contractor’s identity can therefore be read in its rig names and its logo on a hull as much as in any brochure.

A merger name with a pending sequel.

Valaris may not keep its independence for long. On 9 February 2026, World Oil reported, Transocean agreed to acquire Valaris in an all-stock transaction, under which Valaris shareholders would own about 47 percent of the combined company. The companies said the merged fleet would number 73 rigs, including 33 ultra-deepwater drillships, nine semi-submersibles and 31 jackups, and Valaris chief executive Anton Dibowitz said the combined company would be able to operate rigs in any water depth and offshore environment.

Baird Maritime reported on 5 November 2026 that the merger had received all required regulatory approvals, with no conditions imposed by the US Department of Justice or Brazil’s competition authority, CADE. Shareholder votes at both companies were scheduled for 24 November, a Bermuda court approval was expected on 26 November, and closing was expected on or about 1 December 2026. At the time of writing the deal was agreed in February 2026 and not completed, and Valaris was still trading as a separate company.

For now the Valaris name sits on a fleet assembled from Ensco, Rowan and the companies Ensco bought before them, including Pride International and Atwood Oceanics. If the Transocean deal completes, that fleet will join one whose own history, by Transocean’s account, goes back to a Gulf of Mexico jackup of 1954.

For a design guide, Valaris shows how a merger can be given a new name and a plain numbering system to tie together rigs from several predecessors; compare Transocean, which agreed to acquire it, and Noble Corporation, another offshore driller built through mergers. For this guide we use deep teal, sea mist and brass with a sans, an unofficial interpretation; no product or logo is reproduced.
