Tsakos Energy Navigation Brand Guidelines: Oslo in 1993, New York in 2002, TEN Since 2024

A Bermuda company run from Athens.

Tsakos Energy Navigation began in 1993. The company says it was founded in Bermuda that year, and a press release of October 2023 says it was listed on the Oslo Stock Exchange in 1993 and transferred its listing to the New York Stock Exchange in March 2002. It started, the same release says, with a fleet of four tankers. Its offices are in Palaio Faliro, in the Athens area, according to its press releases, which carry the dateline “Athens, Greece.”

Its founder is Nikolas P. Tsakos, who still leads it as founder and chief executive. English Wikipedia describes him as the founder, president and CEO of TEN and as the son of Panagiotis Tsakos, a former ship’s captain from Chios who founded what became the Tsakos Group in the early 1970s. It adds that Nikolas Tsakos chaired INTERTANKO, the association of independent tanker owners, from 2014 to 2018. In its July 2026 release the company named George Saroglou as its president and chief operating officer.

TEN is the listed member of a wider family group. English Wikipedia says the Tsakos Group grew to include tanker, container and bulk carrier operations, with offices in Athens and Montevideo. TEN’s own website names Tsakos Shipping and Trading as its technical manager, and says that manager employs more than 3,500 seafarers on the fleet it manages, from countries including Greece, the Philippines and Romania.

Crude, products, gas and shuttles.

TEN says it owns VLCCs, Suezmaxes, Aframaxes, Panamaxes, handysize and handymax tankers, as well as LNG carriers and shuttle tankers, and calls itself a “one stop shipping company.” Its fleet list in November 2026 shows VLCCs such as Dias I and Hercules I, Suezmaxes such as Arctic and Antarctic, built in 2007 with the Ice 1A class notation, and four Aframaxes built in 2017 with Ice Class 1B: Stavanger TS, Bergen TS, Oslo TS and Sola TS. The company says it has built up 25 ice-class vessels, which can reach ports in certain thicknesses of ice, and that it has grown to become one of the largest ice-class tanker operators in the world.

Gas and offshore work followed. TEN says it entered the LNG market with Neo Energy in 2007 and added Maria Energy in 2016, and entered shuttle tankers in 2013 with two DP2 Suezmaxes, Rio 2016 and Brasil 2014, followed by Lisboa in 2017. A shuttle tanker with dynamic positioning, or DP, holds its station while it loads oil from an offshore field, as MarineLink explained in August 2026. In October 2023 the company said it had taken delivery of Njord DF, the first of four LNG-powered Aframaxes; its fleet list shows the other three, Ran DF, Chios DF and Ithaki DF, built in 2023 and 2024.

Shuttle tankers now run through much of its order book. On 12 August 2026 MarineLink reported that nine 155,000-dwt DP2 shuttle tankers ordered by TEN at Samsung Heavy Industries had each been fixed to Transpetro, the logistics arm of Petrobras, for ten years with an optional five more, with the first two due in the second half of 2027 and the other seven in 2028. On 24 July 2026 the company announced the delivery of Anfield DP, the third of a series of twelve DP2 shuttle tankers under construction at Samsung, for ten years’ employment with a US oil major, and said it had worked in the Brazilian offshore market since 2012.

How tanker owners present themselves.

Tanker owners rarely sell to the public, so their brands live mostly on corporate websites, in investor material and on the ships themselves. The pattern is consistent across the companies in this series: a short purpose line, a fleet page, an investor section and a sustainability page, set in restrained corporate type and colour. The palettes in these guides, from navy and steel to deep sea greens, are tones of our own choosing rather than any company’s colours.

Photographs do much of the work. Owners publish photographs of their own crude and product tankers, and Ardmore Shipping’s homepage, for example, pairs its values with pictures of named ships from its fleet. The ship names themselves often carry the identity: Ardmore puts its own name on every hull, while Okeanis names its tankers after Greek islands.

The fleet list is the core document. Companies set out their ships by size class, from Medium Range (MR) and Handysize product tankers to Suezmax and VLCC crude carriers, usually with the year built, the shipyard, the deadweight and the flag, and they list newbuildings on order with expected delivery dates. Pages on pools, chartering arms and ship-management partners explain who markets and runs the ships commercially and technically.

Many of these companies are listed, so investor pages sit close to the top of the menu: press releases, quarterly results, presentations, filings with regulators and share data, sometimes for two stock exchanges at once. ESG and sustainability reports, often published once a year and prepared with reference to named reporting frameworks, complete the picture. This guide sets out what each company’s own pages and dated independent sources show about its history, ownership and fleet, and keeps the company’s own claims marked as its own.

From TNP to three capitals.

The company now leads with its initials. On 14 June 2024 it announced that from 1 July 2024 its common shares on the New York Stock Exchange would trade as TEN instead of TNP, with its Series E and Series F preferred shares changing to match, while the listing kept the full name, Tsakos Energy Navigation Limited. George Saroglou called the change “a strategic step to better align our brand.” Its releases now open with “TEN, Ltd.”, and its website sits at tenn.gr, a Greek domain spelled with a double n.

Its fleet names mix Greek myth and geography — Hercules I, Artemis Voyager, Chios DF, Ithaki DF — with Norwegian place names on its ice-class Aframaxes and city names such as Athens 04 and Paris 24 on its newest shuttle tankers, both delivered from Samsung in 2025. Its newbuilding list of September 2026 adds Panamax LR1 tankers named Amazona, Maya, Inca and Aztec.

The fleet is being renewed as it grows. On 1 September 2026 TEN announced the sale of two Suezmaxes built in 2006, and on 28 September the sale of the Panamax Andes, built in Japan in 2003 and the oldest ship in its fleet; the second release described a 26-vessel newbuilding programme, seven of which had been delivered. Its 1 September release put the fleet, counting ships on order, at 81 vessels.

For a design guide, Tsakos Energy Navigation shows how a long-listed shipowner can move a family name into a set of initials while keeping the full name in the formal record. Compare Okeanis, another tanker owner listed in both Oslo and New York, and Teekay, a tanker name whose history also runs through offshore oil. For this guide we use an Aegean navy, a steel grey and a sea blue with a sans, an unofficial interpretation; no product or logo is reproduced.
