How did International Seaways become a leading global tanker operator?
International Seaways spun out of Overseas Shipholding Group in late 2016 to focus on international crude and product tanker markets. Headquartered in New York, it grew a diversified fleet and disciplined capital allocation to capture global energy trade flows.
Founded in 2016 after the spin-off, the company scaled to about 77 vessels across VLCC, Suezmax, Aframax and MR classes, blending spot exposure with time-charters and reaching a market cap above $2 billion by 2025. International Seaways Porter's Five Forces Analysis
What is the International Seaways Founding Story?
International Seaways was formally spun off from Overseas Shipholding Group on November 30, 2016, creating a standalone, US-listed platform focused on international tanker operations and growth.
Founding Story
The spin-off separated the international tanker fleet from the Jones Act US-flag business, enabling a focused strategy for crude and product tanker services.
- The formal inception date was November 30, 2016, marking International Seaways history and the start of its corporate timeline.
- Founded via distribution of common stock to OSG shareholders and new independent credit facilities to fund operations and growth.
- Started with a fleet of 55 vessels—including 11 crude oil tankers and 44 product carriers—and stakes in joint ventures.
- Leadership: Lois Zabrocky as President and CEO and Jeffrey Pribor as CFO, providing maritime and financial expertise during the company founding.
Management prioritized building independent corporate infrastructure, brand identity, and a transparent, well-capitalized profile to win major oil company charters in a fragmented tanker market.
Initial balance-sheet actions included establishing committed credit lines; by 2017 the company reported consolidated liquidity (cash plus undrawn credit) exceeding $200 million, supporting fleet employment and repositioning.
The founding chapter in the International Seaways company profile set the stage for subsequent fleet evolution and strategic growth; see an analysis of its commercial model at Revenue Streams & Business Model of International Seaways.

What Drove the Early Growth of International Seaways?
Following its 2016 independence, International Seaways pursued rapid fleet optimization and market expansion, modernizing tonnage and broadening its trading footprint across major crude hubs.
Fleet modernization via targeted acquisitions
In 2018 the company acquired six Very Large Crude Carriers from Euronav for approximately $434,000,000, materially lowering average fleet age and increasing crude exposure.
Geographic expansion of trade routes
Operations during this phase emphasized loading hubs in the Middle East, West Africa and the US Gulf with deliveries to refineries across Asia and Europe, expanding the company profile and revenue diversification.
Capital recycling strategy
Leadership sold older, less efficient vessels and used proceeds to fund modern tonnage purchases, improving fuel efficiency and reducing operating cost per ton-mile.
Transformative merger with Diamond S Shipping
In July 2021 an all-stock merger with Diamond S Shipping added 64 vessels, nearly doubling fleet size and positioning International Seaways as the second-largest US-listed tanker company by vessel count.
Post-merger synergies cut G&A by more than $20,000,000 annually; strong tanker markets in 2022–2023 produced record net income enabling high-interest debt reduction and a capital return program that shifted the company into a diversified, scale-driven operator.

What are the key Milestones in International Seaways history?
Milestones, Innovations and Challenges chart International Seaways company profile through LNG dual-fuel VLCC deliveries in 2023, safety and patent recognitions, COVID-19 era market swings, the 2022 Russia-Ukraine shock and Red Sea disruptions in 2024–2025 that tested operational and financial resilience.
| Year | Milestone |
|---|---|
| 2023 | Delivery of three LNG dual-fuel VLCCs on long-term charters to Shell, reducing CO2 emissions by up to 20%. |
| 2020 | Encountered extreme tanker-market volatility during COVID-19 with initial demand shock followed by record rates from floating storage. |
| 2024–mid-2025 | Managed Red Sea crisis impacts by rerouting vessels around the Cape of Good Hope and reached a net loan-to-value ratio near 15%. |
International Seaways holds multiple patents and operational awards for safety management systems, supporting major charterers such as ExxonMobil and BP. The company leveraged a disciplined capital approach to transform from defensive operations to targeted growth.
LNG Dual-Fuel VLCCs
Three LNG dual-fuel VLCCs delivered in 2023 on long-term charters, demonstrating practical decarbonization aligned with IMO 2030/2050 targets.
Patented Safety Systems
Secured patents and operational awards for safety management, enhancing reputation across major oil companies and reducing incident risk.
Technological Integration
Adopted voyage optimization and emissions-monitoring systems to improve fuel efficiency and compliance reporting.
Long-Term Charters
Securing long-term charters with global energy firms provided revenue stability during market turbulence.
Financial Discipline

Charterer Confidence
Consistent safety and operational performance preserved relationships with charterers like Shell, ExxonMobil and BP.
Market volatility from the COVID-19 demand crash and later floating storage surge created extreme earnings swings that required flexible deployment strategies. Geopolitical disruptions in 2022 and the Red Sea crisis in 2024–2025 lengthened voyages, raised costs and heightened insurance and security expenses.
COVID-19 Market Shock
Global demand collapse in 2020 caused sharp rate declines, then an unexpected spike due to floating storage needs that distorted freight markets for months.
Russia-Ukraine Geopolitical Risk
Sanctions and energy flows altered tanker trade patterns, increasing voyage complexity and counterparty risk across 2022 and beyond.
Red Sea Transit Crisis
Attacks and route closures forced longer passages via the Cape of Good Hope, raising bunker consumption and voyage time in 2024–2025.
Insurance and Security Costs
Heightened premiums and security measures materially increased voyage operating expenses during crisis periods.
Market Rate Volatility
Freight rate swings required agile commercial strategies to optimize fleet utilization and counterparty exposure.
Capital Allocation Constraints
Balancing investment in green tonnage with shareholder returns forced conservative financing choices and staged fleet renewal.
