Who pays International Seaways and which energy firms anchor its customer base?
International Seaways serves major oil majors, trading houses, and commodity traders that need reliable, compliant tanker capacity. These customers matter because they drive stable contract coverage and premium TCE rates; in 2025 chartering patterns show higher demand from refiners adjusting to Atlantic Basin flows.
Core customers are global oil majors and large traders with strict ESG and scheduling needs, so contract longevity rises and spot exposure falls. See the International Seaways Business Model Canvas for service-product mapping.
WWho Is International Seaways Built For?
International Seaways is built for large, creditworthy charterers-supermajor oil companies, national oil companies, and major independent refiners-requiring long – haul, high – specification tanker capacity. The company's core customers demand audit – grade safety, ESG reporting, and reliable crude and product logistics.
Main customer group: supermajors and state oil companies
These primary International Seaways customers include Shell, BP, TotalEnergies, Saudi Aramco, and Petrobras; they drive long-term time charters and require VLCC, Suezmax, and Aframax capacity for crude moves. In early 2026 the fleet totals approximately 77 vessels, supporting multiyear contracts and large cargo volumes.
Secondary groups: refiners, commodity traders, and brokers
Large independent refiners and commodity trading houses charter MR and LR product tankers for refined product flows; shipping brokers arrange both spot and period business. These International Seaways client segments supply flexible demand and spot-market revenue when time-charter coverage gaps occur.
Customer type and market role: institutional B2B service
International Seaways serves institutional business clients-energy corporates, state entities, and trading houses-not retail consumers. Contracts include time charters, voyage charters, and pool arrangements, with an emphasis on creditworthy counterparties and long-term logistics partnerships.
Most important segment in 2025/2026: crude long-haul time charters
Crude long-haul charters for VLCCs and Suezmaxes were the largest revenue drivers in 2025, supported by multiyear agreements with major oil companies and national oil companies; product tankers (MR/LR) provide diversification and higher utilization in regional trades.

WWhat Do International Seaways's Customers Care About Most?
International Seaways customers prioritize operational reliability, regulatory compliance, and fuel efficiency to minimize voyage cost and meet decarbonization targets; they need flexible scale-either immediate spot availability or multi-year time charters-to manage price arbitrage and supply security.
Operational reliability and vetting compliance
High-caliber charterers-oil company charterers, refiners, national oil companies, and commodity traders-require vessels consistently cleared by leading vetting providers and low off-hire rates; downtime costs a charterer tens of thousands per day.
Practical buying drivers: carbon intensity and fuel efficiency
In the 2025/2026 regulatory environment, International Seaways customers demand low Carbon Intensity Indicator (CII) scores and fuel-efficient voyages; International Seaways has fitted energy-saving devices and scrubbers on over 50 percent of its large-vessel capacity to lower fuel burn and voyage costs.
Emotional or aspirational appeal
Clients seek reputation protection and ESG alignment; contracting with a vetted, lower-CII partner supports major oil companies using International Seaways to meet public decarbonization targets and investor expectations.
What customers value most
Customers value predictable voyage economics, regulatory-ready vessels, and flexible commercial options-spot cargoes for arbitrage or secured three-to-five-year time charters that stabilize logistics and costs.
Loyalty or repeat demand
Repeat demand comes from consistent on-time performance, low off-hire, competitive voyage economics, and proven CII improvements; long-term contracts with International Seaways reduce procurement friction for repeat charterers.
Why customers choose International Seaways
Core customers choose International Seaways for its blend of scale, vetted operational track record, and measurable fuel-efficiency retrofit program that helps tanker shipping customers and marine transportation clients meet both short-term arbitrage needs and multi-year supply commitments; see Product Growth of International Seaways Company for related company trends.

WWhere Is Demand Strongest for International Seaways?
Demand is strongest on long-haul tanker routes that maximize ton-mile utilization, led by Atlantic Basin exports to Asian refining hubs and extended Middle East-Europe and Asia-Europe flows.
Main Market: Atlantic-to-Asia Long-Haul Corridors
Atlantic Basin exports from the US Gulf Coast, Brazil, and Guyana to China and India drive the largest ton-mile demand; these long-haul lanes account for the bulk of International Seaways customers seeking LR2 and Suezmax capacity.
Secondary Demand Areas: Middle East-Europe and Asia-Europe
Refined-product and crude flows from the Middle East into Europe and intra-Asia Europe-bound shipments have surged post-2023, creating strong demand from oil company charterers and commodity traders for time-charter and spot market customers.
Where International Seaways Is Strongest
International Seaways shows strength in long-haul Suezmax and LR2 deployment, with fleet utilization frequently exceeding 95 percent in 2025-2026 and revenue mix skewed to long-duration voyages from major oil companies using International Seaways and large commodity traders chartering International Seaways vessels.
Where Demand Is Growing Fastest
Growth is concentrated in exports tied to new Guyana and Brazilian output and longer Middle East-to-Europe refined-product runs; national oil companies as clients and refiners contracting International Seaways for crude transport are increasingly active, supporting tight market fundamentals as newbuild tanker supply remained constrained in the mid-2020s.

HHow Does International Seaways Broaden Appeal Without Losing Focus?
International Seaways broadens appeal by combining a barbell fleet that serves both crude and refined product markets while returning capital to investors, keeping its core oil-major and trader customers served and its financial stakeholders engaged.
Expanding into Adjacent Cargo Markets
International Seaways adds customers by running a dual crude-and-product fleet that attracts oil company charterers, refiners, and commodity traders; this lets it win both spot market customers of International Seaways and longer time charter customers for International Seaways tankers.
Keeping Core Customers Engaged
Operational reliability, specialized vessel classes, and long-term contracts keep major oil companies using International Seaways and national oil companies as clients of International Seaways; steady service for gasoline, diesel, and jet fuel underpins repeat business.
Customer Loyalty and Depth
High-utilization charters and integrated scheduling create ecosystem stickiness: refiners contracting International Seaways for crude transport and oil company charterers prefer repeat bookings, raising renewal probability and deeper usage across routes.
Strongest Growth Lever in 2025-2026
The main growth lever is the barbell strategy plus disciplined capital returns: International Seaways paid over $500,000,000 to shareholders in 2024-2025 and entered 2026 with a conservative net-loan-to-value below 25 percent, which attracts investors while supporting fleet deployment to tanker shipping customers and shipping brokers arranging charters with International Seaways.
