Table of Contents
Introduction to the Oil Tanker Industry
Oil tankers transport crude oil and refined petroleum products between producing regions, refineries, storage terminals and end markets. They form a critical part of international energy logistics, connecting oil supply with demand across different regions.
The sector includes companies with distinct operating models. Some specialize in very large crude carriers (VLCCs), while others focus on Suezmax or Aframax tankers. Product tanker operators transport refined fuels such as gasoline, diesel and jet fuel. Diversified shipping groups may operate oil tankers alongside gas carriers, bulk carriers, container ships and other maritime assets.
These differences matter when comparing companies. A business operating a large number of medium-range product tankers cannot be compared directly with a VLCC specialist using vessel count alone. Corporate structures also affect reported figures: a parent company's total fleet may include vessels that do not transport oil.
This article examines 10 major companies and groups with material involvement in oil tanker shipping. It focuses on their business models, vessel categories and published fleet disclosures. The companies are not ranked by investment quality, profitability or market capitalization.
How the Companies Were Selected
The selection includes specialist crude tanker operators, product tanker companies and diversified groups with significant tanker activities. The profiles prioritize primary company disclosures, annual reports and official fleet pages.
Fleet statistics are presented with their reporting dates and definitions wherever these could be verified. The following measures are not interchangeable:
Owned fleet: vessels the company owns.
Operating fleet: vessels the company operates, which may include chartered-in vessels.
Total group fleet: vessels across the parent company's different shipping businesses.
Newbuilding fleet: vessels ordered but not yet delivered.
The figures below come from different reporting dates because companies publish information on different schedules. They should not be interpreted as a single-date ranking. Where a current comparable figure could not be verified, the article identifies that limitation rather than substituting an estimate.
List of Top 10 Oil Tanker Companies
Frontline: A Modern and Youthful Fleet at the Forefront
Frontline is a publicly listed tanker company focused on the seaborne transportation of crude oil and related petroleum products. Its fleet spans VLCC, Suezmax and LR2/Aframax vessels, providing exposure to different vessel sizes and route requirements.
According to Frontline's 2025 annual report, the company owned 80 vessels as of 31 December 2025: 41 VLCCs, 21 Suezmax tankers and 18 LR2/Aframax tankers. The fleet's aggregate capacity was approximately 17.6 million deadweight tonnes (DWT).
These dated figures replace older fleet counts that may no longer reflect the company's reported fleet. Frontline's fleet employment also differs by vessel class, so fleet composition alone does not establish the company's earnings or operating performance.
Key takeaway: Frontline's 2025 year-end filing provides a clear, dated breakdown of its crude and product tanker fleet.
International Seaways Limited: A Global Crude & Product Carrier
International Seaways transports crude oil and petroleum products through two principal business segments: crude tankers and product carriers. Its fleet includes VLCC, Suezmax and Aframax crude tankers, alongside LR2, LR1 and MR product carriers.
The company's 2025 Form 10-K reported an operating fleet of 70 vessels as of 31 December 2025, comprising 62 owned vessels and eight chartered-in vessels under the filing's stated definition. It also reported four LR1 newbuildings contracted for delivery during 2026, bringing its operating and newbuilding fleet to 74 vessels.
Operating vessels and newbuildings should be reported separately. Ships under construction can contribute to future capacity, but they are not yet part of the operating fleet.
Key takeaway: International Seaways operates across crude and product tanker segments; its reporting distinguishes the operating fleet from vessels awaiting delivery.
Scorpio Tankers: A Leader in Product Tanker Logistics
Scorpio Tankers specializes in transporting refined petroleum products. Its fleet includes Handymax, MR and LR2 product tankers, which serve different cargo volumes and voyage requirements.
Scorpio Tankers' 2025 sustainability report lists 89 vessels as of 31 March 2026, compared with 99 in 2024. The report also records an average fleet age of 10.1 years as of that date. These figures should be cited with the report's stated date rather than presented as a guaranteed current fleet count for October 2026.
The company is listed on the New York Stock Exchange under the ticker STNG. Its business is best assessed in the product tanker segment, where refinery locations, refined-fuel trade flows, voyage distances and vessel availability influence demand.
Key takeaway: Scorpio Tankers is a product tanker specialist; its fleet count and average age should be reported with the source date.
DHT Holdings: Specializing in VLCC Crude Transportation
DHT Holdings specializes in owning and operating VLCCs, which are designed to transport large crude oil cargoes on suitable long-haul routes.
DHT's 2025 annual filing reported 22 VLCCs as of 31 December 2025, with a combined carrying capacity of approximately 6.84 million DWT. The company is listed on the New York Stock Exchange.
A concentrated fleet gives DHT a clear position in the VLCC segment, but it also means that its operations are closely linked to conditions affecting that market. Freight rates, route changes, vessel availability, maintenance and operating expenses can influence financial performance.
Key takeaway: DHT is a VLCC specialist; its 2025 year-end fleet and capacity disclosures provide a consistent baseline for comparison.

Hafnia
Hafnia is a product and chemical tanker operator with vessels across segments including Handy, MR, LR1 and LR2. Its fleet structure includes owned vessels and vessels operating under other arrangements.
Hafnia's official fleet page lists 173 vessels in total, of which 87 are owned. The same page distinguishes bareboat, operated and time-chartered-in vessels. Because the fleet page can change as vessels enter or leave the fleet, its figures should be recorded with the date on which the page is checked.
The company also operates through commercial pools involving vessels of similar sizes. Pool arrangements coordinate commercial employment but do not remove exposure to freight-rate changes, operating costs or shifts in cargo demand.
Key takeaway: Hafnia is a major product tanker operator, but its total fleet count must not be confused with its owned fleet.

TORM Tankers: Specialized in Clean Petroleum Products
TORM specializes in transporting refined petroleum products, with vessels across LR2, LR1, MR and other product tanker segments. Its business connects refineries, storage terminals and end markets through international shipping services.
TORM's investor disclosures state that the company took delivery of two MR vessels in the second quarter of 2026, increasing its fleet to 97 vessels. The company also reported agreements for additional MR vessels scheduled for delivery from 2027 onwards, with further newbuildings planned for later years.
This makes the reporting date important: the fleet count can change as vessels are delivered, sold or transferred into full ownership. Newbuilding commitments should be listed separately from vessels already in service.
Key takeaway: TORM's second-quarter 2026 disclosure provides a dated fleet count and describes planned additions to its product tanker fleet.
Tsakos Energy Navigation (TEN Ltd): Diversified Energy Carriers
Tsakos Energy Navigation (TEN Ltd), headquartered in Athens, Greece, is a maritime energy transportation company specializing in crude oil, petroleum products and selected gas transportation services. Its fleet includes conventional oil tankers, LNG carriers and DP2 shuttle tankers, allowing the company to serve different cargo requirements and operating environments.
As of 30 March 2026, TEN reported an operational fleet of 64 double-hull vessels, with a total carrying capacity of approximately 8.0 million deadweight tonnes (DWT) and an average fleet age of 10.3 years. The fleet comprised three VLCCs, 14 Suezmax tankers, 24 Aframax tankers, two Aframax LR2 vessels, nine Panamax LR1 tankers, two MR vessels, two Handysize MR1 vessels, two LNG carriers and six DP2 shuttle tankers. Fourteen vessels had ice-class specifications. The company also reported additional vessels under construction for delivery across 2026–2028.
TEN recorded US$798.7 million in voyage revenue for the 2025 financial year, compared with US$804.1 million in 2024. For the six months ended 30 June 2026, reported voyage revenue was US$551.4 million, compared with US$390.4 million in the same period of 2025. These are voyage-revenue figures, not market capitalisation or total asset values.
TEN's common shares trade on the New York Stock Exchange under the ticker TNP. Its diversified fleet means that the company should be assessed across its different vessel classes rather than treated as a pure-play VLCC or product tanker operator.
Key takeaway: TEN combines crude and product tankers with LNG and shuttle tanker operations. Its latest verified fleet breakdown is dated 30 March 2026; market capitalisation and total assets should only be included when supported by a dated financial or market source.
CMB.TECH: The Independent Crude Oil Transportation Specialist
CMB.TECH is a diversified maritime group with activities spanning crude oil tankers, dry bulk shipping, container transport, chemical tankers and other maritime businesses. The company was formerly known as Euronav NV; the corporate name change took effect on 1 October 2024. The Euronav name continues to be used for its crude tanker and offshore oil activities.
CMB.TECH's 2025 annual report recorded a total shipping fleet of 205 vessels for the group in its sustainability disclosures. This is a group-wide figure, not a count of oil tankers alone. The report also notes that the fleet composition changed materially in 2025 following the merger with Golden Ocean, making direct year-on-year comparisons difficult.
For readers evaluating tanker operators, this distinction is important. Euronav's group-wide fleet and financial results include businesses beyond crude oil transportation, so they should not be presented as Euronav-only statistics.
Key takeaway: Use CMB.TECH as the current corporate name and identify its Euronav business separately when discussing crude tanker operations.
Sources: CMB.TECH 2025 Annual Report and CMB.TECH's name-change announcement.
Nordic American Tankers
Nordic American Tankers (NAT) focuses on Suezmax crude oil tankers. These vessels transport crude oil in cargo volumes and on routes that differ from those served by VLCCs.
In a fleet update dated 14 March 2025, NAT stated that following two vessel acquisitions, its fleet would consist of 21 Suezmax tankers. This is a dated company disclosure and should not be treated as a verified October 2026 fleet count without a newer confirmation.
A focused fleet makes NAT relevant to Suezmax market comparisons, but vessel count alone does not indicate profitability. Vessel age, employment arrangements, operating costs, financing and freight-market conditions also affect performance.
Key takeaway: NAT is a Suezmax-focused operator; the 21-vessel figure must retain its March 2025 date until a newer company disclosure is verified.
COSCO SHIPPING Energy Transportation
COSCO SHIPPING Energy Transportation operates in energy transportation within the broader COSCO SHIPPING group. It should be distinguished from the parent group, whose activities extend across multiple shipping and logistics businesses.
For this company, the fleet count, financial results and vessel categories should be drawn from its own latest annual report or official investor disclosure. Parent-group totals should not be attributed to the energy transportation business unless the report explicitly identifies them as subsidiary figures.
A current, comparable fleet count was not verified for this draft. Rather than reproduce an undated number, the article leaves the figure for confirmation from the latest subsidiary-specific disclosure.
Key takeaway: COSCO SHIPPING Energy Transportation belongs in a broad tanker-market overview, but its statistics must be kept separate from parent-group totals.
Source: COSCO SHIPPING Holdings — Official Website. Confirm the latest subsidiary-specific annual report before publishing fleet or financial figures.
Comparison of Oil Tanker Companies
The table below summarizes the fleet data that could be verified from company disclosures. It is not a numerical ranking: the dates and fleet definitions differ, and the figures are not directly comparable in every case.
Company | Main tanker focus | Published fleet figure | Reporting date and definition |
Frontline | Crude and product tankers | 80 owned vessels | 31 December 2025 |
International Seaways | Crude and product tankers | 70 operating vessels; 4 additional newbuildings | 31 December 2025 |
Scorpio Tankers | Product tankers | 89 vessels | 31 March 2026 |
DHT Holdings | VLCC crude tankers | 22 VLCCs | 31 December 2025 |
Hafnia | Product and chemical tankers | 173 total vessels; 87 owned | Official fleet page; verify date at publication |
TORM | Product tankers | 97 vessels | Q2 2026 |
Tsakos Energy Navigation (TEN Ltd) | Crude, product, LNG and shuttle tankers | 64 double-hull vessels | 30 March 2026 |
CMB.TECH (formerly Euronav) | Crude tankers within a diversified group | 205 vessels across the group's total shipping fleet | 2025 annual report; group-wide figure, not tanker-only |
Ardmore Shipping | Product and chemical tankers | 25 owned and operated; 1 chartered in | 31 December 2025 |
Nordic American Tankers | Suezmax crude tankers | 21 vessels | Company update dated 14 March 2025 |
Comparison note: Fleet size is only one dimension of a tanker business. DWT, vessel class, ownership structure, charter arrangements, vessel age and reporting date should be considered before comparing capacity or operational exposure. Market capitalization, revenue and assets have been excluded because a comparable, consistently dated dataset was not established for all ten companies.
Factors Shaping the Tanker Industry
Freight rates and route conditions
Tanker earnings are influenced by cargo demand, available vessel capacity, voyage distance, port congestion, route disruption and the balance between spot and time-charter employment. A larger fleet does not automatically produce stronger earnings if freight rates are weak or vessels are underutilized.
Vessel type and cargo
VLCC and Suezmax operators primarily focus on crude oil transportation. MR, LR1 and LR2 vessels are important in refined-product trades. Vessel size, cargo characteristics, draft restrictions and route economics influence which markets an operator can serve.
Fleet renewal and regulation
Vessel age, fuel consumption, maintenance requirements and environmental regulations affect fleet investment decisions. Newbuildings can add future capacity, but they also involve capital commitments, delivery schedules and financing considerations.
Ownership, chartering and financing
Companies differ in the proportion of vessels they own outright, lease or charter. These arrangements affect reported assets, debt, operating flexibility and fleet comparability. Analysts should review the underlying disclosures rather than treating every reported vessel count as equivalent.
Corporate structure and reporting dates
Mergers, acquisitions, name changes and asset sales can alter which entity owns or operates a fleet. Historical company names and statistics should be updated to reflect the current corporate structure. Every material fleet or financial figure should be accompanied by a source and a date.
Conclusion
Oil tanker companies operate across different market segments, from VLCC and Suezmax crude transportation to refined petroleum product and chemical shipping. Frontline, International Seaways and DHT Holdings focus on crude tanker operations, while Scorpio Tankers, Hafnia and TORM specialize primarily in product tanker markets. Companies such as Tsakos Energy Navigation and CMB.TECH have broader maritime portfolios that require group-wide fleet figures to be distinguished from tanker-specific data.
Comparing these companies requires more than counting vessels. Fleet ownership, vessel class, deadweight tonnage (DWT), charter arrangements, vessel age and reporting dates all affect how their operations should be assessed. Newbuildings should also be separated from operating vessels, and diversified groups should not be compared directly with specialist tanker operators using total fleet figures alone.
The fleet data presented in this article provides a dated overview of the selected companies, based on the disclosures identified for each profile. Because the reporting periods and fleet definitions vary, the figures should not be interpreted as a definitive ranking by fleet size or financial performance. Readers should consult each company's latest annual report and official fleet disclosures for updated information.
Ultimately, a meaningful comparison begins with a clearly defined metric and consistent source data. This approach provides a more reliable basis for understanding the structure of the oil tanker shipping industry and the differences between its major operators.
Frequently Asked Questions
What are the main types of oil tanker companies?
Some companies focus on crude oil tankers, including VLCC and Suezmax operators. Others specialize in product tankers that transport refined fuels, while some operate both types. Diversified shipping groups may own tankers alongside bulk carriers, gas carriers, container ships and other maritime assets.
How should oil tanker companies be compared?
Start by defining the comparison metric. Fleet size can refer to owned vessels, operated vessels, deadweight capacity or a count that includes newbuildings. Financial comparisons should use consistent reporting periods and currencies, and should distinguish market capitalization from enterprise value, revenue and total assets.
What is the difference between a VLCC and a Suezmax tanker?
A VLCC is a very large crude carrier designed to transport large crude cargoes on suitable routes. A Suezmax tanker is sized around the relevant operating constraints for transiting the Suez Canal. Actual cargo capacity depends on vessel design, draft, cargo density and operating conditions.
Why do tanker fleet numbers change?
Fleet numbers change when companies acquire or sell vessels, take delivery of newbuildings, charter vessels in or out, or restructure their businesses. Sources may also count owned, operated and chartered vessels differently. Check the reporting date and fleet definition before comparing companies.
Does a larger tanker fleet mean better financial performance?
No. Fleet size alone does not establish profitability or investment quality. Earnings are influenced by freight rates, utilization, operating expenses, financing costs, vessel age, debt and capital commitments. A meaningful assessment requires current company disclosures and a consistent comparison method.
What should readers check before relying on a company's fleet figures?
Readers should identify the source, reporting date and fleet definition. They should also check whether the number includes chartered vessels, subsidiaries, vessels under construction or non-tanker assets. These distinctions help prevent misleading comparisons between companies with different business models.
