## Products & services

International Seaways transports crude oil and refined petroleum products by sea. Its Product Carriers move gasoline, diesel, jet fuel, heating oil, vegetable oils and organic chemicals such as methanol and ethylene glycols between refineries and consuming markets. The company’s MR carriers meet IMO III requirements, enabling them to carry edible oils, including palm and vegetable oils. [3](https://app.finbar.com/go?id=P119152535)

Its crude-tanker services include ship-to-ship lightering. Support-only lightering supplies personnel, hoses and fenders; full-service lightering also provides a vessel, usually an Aframax. These services transfer crude between ships, including from larger vessels whose cargoes may exceed a port’s size or draft limits. [2](https://app.finbar.com/go?id=P50213740) The tanker fleet includes VLCCs, Suezmaxes and Aframaxes; VLCCs are approximately 200,000–320,000 dwt and generally carry two million barrels or more of crude. [6](https://app.finbar.com/go?id=P155131060)[4](https://app.finbar.com/go?id=P39981309)

As of June 30, 2026, the operating fleet comprised 64 wholly owned or lease-financed vessels totaling 7.6 million dwt, including crude tankers and LR2, LR1 and MR product carriers. [6](https://app.finbar.com/go?id=P155131060) Voyage charters—including vessels predominantly trading in commercial pools—accounted for 82% of aggregate TCE revenue in 2025.

## Geographic presence

International Seaways operates an international fleet on worldwide routes. Typical crude-tanker routes include the Arabian Gulf to North America, Europe and Asia; West Africa to the U.S. and Asia; and the Americas to Asia. These are illustrative routes for the vessel class, not a measure of the company’s actual voyage or revenue mix. [4](https://app.finbar.com/go?id=P39981309) Its product carriers transport refined petroleum products worldwide on both long- and short-haul routes. [3](https://app.finbar.com/go?id=P119152535)

The company’s crude-tanker lightering activity includes operations in the U.S. Gulf, U.S. Pacific, Grand Bahama and Panama regions; demand for this activity is affected by U.S. crude imports and exports. [2](https://app.finbar.com/go?id=P50213740) Its principal executive office is in New York City. [10](https://app.finbar.com/go?id=P82182630)[11](https://www.intlseas.com/contact/default.aspx) The available reporting does not provide revenue by country or region, or employee distribution by geography.

## Business segments

International Seaways reports two operating segments: **Crude Tankers** and **Product Carriers**. Crude Tankers comprises VLCC, Suezmax and Aframax vessels transporting crude oil; it also includes the company’s crude-tanker lightering operations, which provide ship-to-ship transfer services. Product Carriers comprises MR and LR1 product carriers and an LR2 vessel transporting refined petroleum products. Lightering is included within Crude Tankers rather than reported as a separate segment. [12](https://app.finbar.com/go?id=P27238136)[13](https://app.finbar.com/go?id=P94483915)[2](https://app.finbar.com/go?id=P50213740)[3](https://app.finbar.com/go?id=P119152535)

By time charter equivalent (TCE) revenue, the approximate segment mix was **58% Crude Tankers and 42% Product Carriers** for the six months ended June 30, 2026. For full-year 2025, the mix was approximately **52% and 48%**, respectively. These percentages reflect revenue contribution, not fleet share.

## Company history

International Seaways, Inc. was incorporated in the Marshall Islands in 1999. It became an independent publicly traded company on November 30, 2016, when Overseas Shipholding Group spun it off to its shareholders; Lois K. Zabrocky became president and chief executive officer at that time. [16](https://app.finbar.com/go?id=P187941722)[17](https://app.finbar.com/go?id=P187941726)[18](https://app.finbar.com/go?id=P187943799)

In 2021, International Seaways completed its merger with Diamond S Shipping, adding 64 vessels and significantly expanding its tanker fleet. That year, it also contracted to build three dual-fuel LNG very large crude carriers (VLCCs), which were delivered in 2023. [19](https://app.finbar.com/go?id=P16076432)[20](https://app.finbar.com/go?id=T362153)[21](https://app.finbar.com/go?id=P2091777)[22](https://www.intlseas.com/newsroom/news/news-details/2023/International-Seaways-Reports-Second-Quarter-2023-Results/default.aspx)

In 2023, the company contracted for four dual-fuel-ready LR1 product tankers, with options for two additional vessels, extending its fleet-renewal program. [23](https://app.finbar.com/go?id=P44097668)
