Vantage Drilling Brand Guidelines: Drillships, ADES Jack-Ups & a 2026 Eldorado Takeover

A driller that changed hands in 2026.

Vantage Drilling is an offshore drilling contractor whose public face changed in 2026. On 29 May 2026 Vantage Drilling International signed an agreement and plan of merger with Eldorado Drilling AS, a drilling company that Offshore Energy described as backed by a group of well-known Norwegian investors. Offshore Energy called Vantage a Bermuda-exempted offshore drilling contractor, and the deal was set up as a statutory merger under Bermuda law, with an Eldorado subsidiary merging into Vantage.

Vantage shareholders approved the merger at a special general meeting on 18 June 2026, World Oil reported, though completion still depended on other closing conditions at that point. On 29 June 2026 Offshore Energy reported that Eldorado had completed the acquisition, with Vantage surviving as an indirect subsidiary of Eldorado. According to Offshore Energy and to Westwood Global Energy Group, the surviving company kept the name Vantage Drilling International.

The web address moved with the deal. In November 2026 the vantagedrilling.com address forwards to the Eldorado Drilling website, which presents the combined business under the Eldorado name with the line “Built on Experience, Driven by Ambition.” That site says the company has been operating since 2007 and that its operational experience goes back to that year. It lists offices in Dubai, Singapore and the Cayman Islands, and describes itself as an offshore drilling contractor with a fleet of modern drillships and managed jack-ups.

Eldorado’s own history before the merger was short and built on rig deals. Westwood reported that it bought two newbuild seventh-generation drillships, West Draco and West Dorado, in 2023 and, without ever putting them to work, sold them in 2025 to TPAO, the state-owned Turkish oil company, which gave them new names. When the merger was agreed, Westwood said, Eldorado’s only working rig was the Atlantic Zonda, a seventh-generation drillship working offshore Brazil under the management of Ventura Offshore.

From rig owner to rig manager.

In the years before the merger Vantage reshaped its fleet. Westwood says it sold five jack-ups to ADES, the Saudi-based drilling group, between 2020 and 2024, while keeping a role in running them through management agreements. In December 2021 it agreed to sell three jack-ups to ADES, Offshore Energy reported in January 2022, and the two companies agreed to explore future commercial and operational work together.

A second sale followed. In September 2024 Offshore Energy reported that the Soehanah, a 375-foot jack-up built in 2009, and the Topaz Driller, a 375-foot jack-up built in 2007, both working in Southeast Asia, would pass to ADES, with Vantage managing each rig for three years. Vantage’s chief executive spoke of a history of collaboration with ADES in Egypt and Qatar. Westwood says the three-year management agreements began in the fourth quarter of 2024.

The drillships moved in a similar direction. In January 2025, Westwood reported, TotalEnergies and Vantage formed a joint venture, TEVA Ship Charter, to own the Tungsten Explorer, with TotalEnergies holding 75 per cent and Vantage managing the rig under a ten-year agreement with an option for five more years. Offshore Energy had noted in September 2024 that Vantage had made arrangements with TotalEnergies over a drillship working for the French company in Namibia. The Platinum Explorer, an ultra-deepwater drillship, stayed with Vantage; in July 2026 Westwood pointed to its upcoming three-year contract with ONGC offshore India.

Vantage also managed rigs for other owners. In March 2021, while Seadrill Partners was in Chapter 11, Vantage was approved as manager of four of its deepwater floaters, the Polaris and Capella drillships and the Leo and Sirius semisubmersibles, Offshore Energy reported; that company was soon renamed Aquadrill. In January 2022 Vantage agreed to manage and market a fifth Aquadrill rig, the harsh-environment semisubmersible Aquarius, built in 2009.

Eldorado’s rigs page now lists four drillships, the Deep Value Driller and Atlantic Zonda, which it calls seventh-generation, and the Tungsten Explorer and Platinum Explorer, which it calls sixth-generation, plus the Soehanah and Topaz Driller as managed jack-ups. Westwood likewise counted four drillships and two managed jack-ups owned by ADES after the deal. Offshore Energy reported in June 2026 that Eldorado had agreed to buy the Deep Value Driller; the sources used for this guide do not confirm whether that purchase has closed. The website also gives its own figures: six rigs operated and managed, a workforce of 40 nationalities, and work in 26 countries.

Design and documentation.

Offshore drilling contractors sell time on rigs rather than goods in a shop, so their public identity is built around the fleet. Their websites tend to pair plain corporate wordmarks, often in navy, red or orange, with large photographs of drillships, semisubmersibles and jack-ups at sea, published by the companies themselves.

The rig is the working unit of the brand. Contractors commonly give each rig its own page with a short run of specifications: the design, the water depth it is rated for, how deep it can drill, how many people it can house, and where and for whom it is working. Shelf Drilling’s fleet page, for example, gives every one of its jack-ups the same set of fields. Rig names often share a prefix or a word, so that the company name travels with each unit from contract to contract.

Fleet-status reports are the other recurring document, listing rigs with their current customers, locations and contract periods for investors and clients. When Noble Corporation completed its acquisition of Diamond Offshore in September 2024, it published an updated fleet status report alongside the announcement, The Maritime Executive reported. Operating-region maps sit next to them, placing rigs in waters from the North Sea to West Africa and Southeast Asia.

Investor pages complete the picture, because the sector has been reshaped by restructurings and mergers. Diamond Offshore went through Chapter 11 in 2020 and 2021 and became part of Noble in 2024; Shelf Drilling became part of ADES in 2025. For designers, these companies show a corporate identity carried by rig names, specification sheets, fleet reports and maps rather than by packaging or retail.

A name kept on paper, a new name online.

The Vantage name now lives mostly in company law and trade reports. The merger kept Vantage Drilling International as the name of the surviving company, but the public website is Eldorado’s, and the rigs once marketed as Vantage’s appear there under the Eldorado heading. Offshore Energy quoted the combined business describing itself as a “scalable offshore drilling platform” with “enhanced” capabilities. Westwood called the merger modest in scale and set it within a wider run of consolidation among offshore drillers, noting that 18 companies managed drillships worldwide before the merger deals then under way had closed.

The company’s story is a useful one for designers because it shows a driller whose main asset became its management team rather than its fleet. After the ADES sales and the TotalEnergies joint venture, Westwood described Vantage as having shifted toward a more asset-light, services-oriented model. On its website the fleet is split into owned drillships and managed rigs, each rig has its own specification sheet, and a regularly updated fleet status report is offered as a download. The site’s other sections cover vision and values, QHSE, sustainability, the management team and careers.

The rig names carry most of the brand’s character. Vantage’s drillships take the names of metals, the Platinum Explorer and the Tungsten Explorer, while the Topaz Driller follows a gemstone; the Deep Value Driller and Atlantic Zonda came to the group through Eldorado. Both jack-ups kept their names when they passed to ADES.

For a design guide, Vantage Drilling shows how a contractor can keep its legal name while its public identity moves to a new owner. Compare ADES, the buyer of its jack-ups, and Aquadrill, whose rigs it managed. For this guide we use a deepwater navy, a pale sea mist and a deck brass with a sans, an unofficial interpretation; no product or logo is reproduced.
