Centerline Logistics Corporation

What Centerline Logistics Corporation does

Centerline Logistics Corporation is a Seattle-headquartered, private marine petroleum transportation operator that runs one of the largest and most technically advanced Jones Act compliant fleets in the United States, with 123 vessels and approximately 3 million barrels of liquid barge carrying capacity. The company traces its origin to 1987 as Olympic Tug & Barge, later operated as Harley Marine Services, and was rebranded Centerline Logistics around 2020; in August 2025 it was acquired by Maritime Partners LLC, a U.S. maritime-focused private equity firm.

The core fleet is built around Articulated Tugs and Barges (ATBs), double-hull bunker and terminal barges, conventional and tractor tugboats, and deck cargo barges, all U.S.-built and U.S.-flagged to comply with the Jones Act, which restricts domestic coastwise trade. The technology differentiator is the ATB architecture — tugs and barges joined by a secure pinning system — combined with the youngest average barge age in the U.S. Jones Act fleet (~12 years), which together support tanker-like safety performance in harsh weather while preserving barge economics. Centerline is RCP-certified by the American Waterways Operators, reflecting sector-specific safety and environmental compliance.

Revenue is generated through transaction-fee, charter-based B2B services across six core offerings: bunkering (vessel refueling), terminal transportation (ATB-based petroleum movement between refineries and terminals), ship assist and escort, rescue and general towing, tank storage and blending in Portland, OR, and weekly freight barge service out of Dutch Harbor, Alaska. Go-to-market is direct enterprise sales to oil majors, refiners, terminal operators, and shipping lines across the West, East, and Gulf Coasts plus Hawaii, Alaska, and Puerto Rico, supported by six regional operations offices. In 2024 the company moved 120M+ barrels of oil across 460K nautical miles, completing 11K jobs for 70+ customers; revenue figures are not publicly disclosed.
