Scale indicators7 records

Recent moves5 records

Expansion highlights5 records

Broad incumbents

• Crowley Maritime: Crowley is one of the largest privately held U.S. maritime operators with a Jones Act tanker, container, and RORO fleet, plus ship management and government services. Directly comparable to Keystone's liquid bulk, RORO, and MARAD-facing operations, but at significantly greater scale and broader segment coverage.
• International Seaways: International Seaways operates a global tanker fleet with both crude and product tankers, including Jones Act exposure. Comparable to Keystone on tanker operations and ship management capabilities, though at much greater scale and predominantly international.

Direct peers

• Kirby Corporation: Kirby is the largest U.S. inland tank barge operator and a major coastal Jones Act transporter of petrochemicals and black oil. Directly comparable to Keystone's petroleum tanker fleet and ATB operations, and the cleanest U.S.-listed peer for Keystone's liquid bulk business.
• Overseas Shipholding Group (OSG): OSG operates a U.S. Flag and international tanker fleet focused on Jones Act and refined product trades. Directly comparable to Keystone's tanker operations and government maritime services exposure.
• American Roll-On Roll-Off Carrier (ARC): ARC is the leading U.S.-flag RORO carrier serving military, government, and commercial customers. Directly comparable to Keystone's RORO and Ready Reserve Force management business.
• Moran Towing Corporation: Moran is one of the largest U.S. tug and barge operators with extensive U.S. flag fleet operations. Comparable to Keystone on tug and tank barge services, government maritime work, and Jones Act-eligible fleet operations.
• Matson Navigation: Matson operates Jones Act container and RORO services between U.S. ports and Hawaii, Guam, and Alaska. Comparable to Keystone's U.S. flag coastwise operations and government logistics services.

Regional players

• Lake Carriers' Association members (Great Lakes bulk operators): The Lake Carriers' Association represents U.S.-flag Great Lakes bulk carriers that transport iron ore, coal, and limestone—the same industrial bulk commodities Keystone's Key Lakes subsidiary serves. Direct competitor set in the Great Lakes bulk trade.

Emerging players

• Star Bulk Carriers: Star Bulk is a global dry bulk shipowner with a large fleet of Newcastlemax, Capesize, and Panamax vessels. Comparable to Keystone's dry bulk transportation activity via Key Lakes, though at vastly larger scale and operating internationally.

Others

• ABS (American Bureau of Shipping): ABS is a leading maritime classification society and Keystone's stated standards partner. Listed here as an ecosystem peer rather than competitor—relevant because ABS classification, standards, and committee participation directly shape Keystone's regulatory and commercial operating environment.
