International Seaways
Lois Zabrocky leads International Seaways, a publicly traded tanker operator controlling a VLCC-to-LR1 fleet spanning crude and product routes globally.
International Seaways
International Seaways launched in 2016 when Overseas Shipholding Group (OSG) restructured through bankruptcy and separated its international and domestic operations into two entities. CEO Lois K. Zabrocky, a OSG veteran who rose through commercial and strategic roles over two decades, took the helm at inception and has run the company since. The firm is not a family office or private investment vehicle — it is a publicly traded tanker company listed on the New York Stock Exchange (NYSE: INSW) that investors can buy directly. The company owns and operates a fleet of roughly 80 vessels, including Very Large Crude Carriers (VLCCs), Suezmaxes, Aframaxes, and Long Range (LR1 and LR2) product tankers. These ships transport crude oil and refined petroleum products across routes in the Middle East, Asia, Europe, and the Americas. International Seaways generates revenue through both spot-market charters, which capture volatile day rates, and fixed-rate time-charters with major energy companies and traders. The dual fleet structure — crude and product tankers — gives it a differentiated exposure to two distinct segments of the global petroleum supply chain. The firm has been active in modernizing its fleet: in 2023 and 2024 it ordered and took delivery of dual-fuel LNG-ready LR1 tankers, positioning the fleet for tightening IMO environmental regulations. The company trades with a market capitalization that has fluctuated between $1.5B and $3B over recent years, reflecting the cyclical nature of tanker rates. Unlike a private family office or asset manager, International Seaways does not disclose an AUM or a dedicated investment team count — its assets are the ships themselves and the contracted cash flows. Its governance is led by a board of directors alongside the executive team, with no single-family or founder-control structure. Adjacent vehicles or philanthropic arms tied to the company or its leadership are not publicly disclosed. In March 2024, International Seaways declared a regular quarterly dividend and continued its share-repurchase program, signaling a capital-return posture common among publicly traded shipping companies during strong rate environments. International Seaways functions as an operating company, not a pooled investment vehicle, which is its core structural distinction for allocators. Anyone evaluating it is assessing a single-public-security equity position in a hard-asset transport business — not a blind-pool fund commitment. The investment thesis turns on tanker-cycle timing, fleet optionality across crude and product markets, and the company's ability to manage capital allocation between vessel acquisitions, debt repayment, and shareholder returns. Succession and governance risk sit with a standard public-company board, removing the key-person risk that family offices or single-CIO funds carry.

Frequently asked questions
Who runs investment decisions at International Seaways?
The company is an operating business, not a fund, so there is no CIO making LP-style allocation decisions. Lois K. Zabrocky, President and CEO, leads the overall strategy, including fleet composition, vessel acquisition and disposal, chartering policy, and capital allocation. The board of directors approves major capital decisions.
How does International Seaways source its revenue opportunities?
Revenue is generated by contracting vessels with oil majors, commodity traders, and national oil companies. The company deploys ships on both spot-market voyages and multi-year time charters. Spot exposure links earnings directly to tanker rate indexes, while time charters provide contracted cash flow visibility.
Is International Seaways structured as a family office or investment fund?
Neither. It is a publicly traded corporation (NYSE: INSW) that owns and operates a fleet of tankers. An investment in International Seaways means buying common stock in a shipping company, not subscribing to a capital commitment in a pooled fund.
What differentiates International Seaways from other tanker operators?
The fleet spans both crude carriers (VLCCs, Suezmaxes, Aframaxes) and product tankers (LR1s, LR2s) under a single public listing, which gives shareholders exposure to two distinct petroleum shipping markets. The company also maintains a significant US-flagged fleet presence from its OSG heritage, which is uncommon among globally trading peers.
Does International Seaways maintain any private investment vehicles or philanthropic arms?
No private investment vehicles or foundations tied to the company or its leadership are publicly disclosed. The firm operates as a single reporting entity under SEC rules, with none of the parallel investment structures common among family offices or alternative asset managers.
What is International Seaways's posture on environmental regulations?
The company is investing in dual-fuel LNG-ready newbuilds and has included vessels capable of meeting IMO 2023 EEXI and CII standards in its fleet renewal program. This positions it for tighter emissions rules in European and high-compliance jurisdictions.
How should an institutional allocator think about an allocation to International Seaways?
As a single-stock equity position in a cyclically exposed hard-asset transport business, not a diversified fund commitment. The analysis centers on tanker supply-demand cycles, oil-trade route shifts, and the management's track record on capital returns. The company does not accept LP capital and has no fee structure.
