Saltchuk Marine

What Saltchuk Marine does

Saltchuk Marine is a Seattle-headquartered marine services division of the Saltchuk family of companies, providing tug and barge operations, tanker assistance, harbor towage, deep-water shipping logistics, and ship management to enterprise customers across the U.S. West Coast, Alaska, Hawaii, the Gulf of Mexico, the U.S. East Coast, and the Caribbean. Its portfolio comprises three wholly-owned operating subsidiaries — Foss Maritime (premier U.S. West Coast harbor towage and global logistics), AmNav Maritime (California ship-assist and offshore towing), and Cook Inlet Tug & Barge (Alaska maritime services, oilfield support, and fuel distribution) — plus the Green Tug Towing (GTT) joint venture with Harbor Docking & Towing, established to serve the Woodside Energy Louisiana LNG terminal under a 20-year contract.

The company's core technology centers on its tugboat fleet and purpose-built vessels, including four new diesel-electric hybrid escort tugboats under construction to Robert Allan Ltd.'s RApport 2800H design by C&C Marine & Repair at Belle Chasse, Louisiana — engineered specifically for LNG carrier safety, maneuverability, and environmental performance. In-house technical and engineering capabilities span naval architecture, marine engineering, vessel design, and construction consultation.

Saltchuk Marine generates revenue primarily through long-term, multi-year service contracts with energy companies (LNG terminal operators, oil & gas firms), construction companies, government/military customers, and port terminals — supplemented by transactional harbor services, fuel and oilfield logistics, and specialized project cargo work. Its largest disclosed commercial win is the 20-year Woodside Energy LNG contract awarded in 2026, with a $300M+ services portion to GTT and first LNG targeted for 2029; the broader Woodside supplier package exceeds $1B. Go-to-market is enterprise B2B via direct sales, competitive bidding, and industry-event relationships, with safety (zero-incidents goal) and environmental stewardship as positioning pillars.
