About the company
Centerline Logistics Corp, operating through its Harley Marine Services division and doing business as Westoil Marine Services, delivers tug assist, harbor assist, and fuel barge transportation services to the Department of Homeland Security's U.S. Coast Guard and U.S. Navy as a prime contractor in full-and-open federal competition, with no set-aside designations across its recent footprint. The for-profit maritime transportation company is headquartered in Seattle, Washington, and competes without SBA certifications or socioeconomic set-aside advantages.
Centerline Logistics Corp's capability portfolio is anchored in small-dollar, tactical maritime logistics for vessel support and fuel delivery. Representative work includes a $240 thousand firm-fixed-price purchase order from U.S. Pacific Fleet Forces (awarded July 2023) for tug and barge services supporting the USS Tulsa through January 2025; a $733 thousand firm-fixed-price purchase order from Naval Supply Systems Command (awarded November 2021) for delivery of 325,000 gallons of JP-5 fuel via barge from Manchester, Washington to Portland, Oregon supporting Navy Region Northwest; and recurring monthly purchase orders from the U.S. Coast Guard—typically $4,000 to $4,144 each—for tug assist services for Coast Guard Cutters Healy and Stratton in Dutch Harbor, Unalaska, Alaska.
Customer concentration is stark. The U.S. Coast Guard accounts for 22 awards (81% of the recent portfolio) but only $113 thousand in combined potential value, reflecting the tactical, repetitive nature of harbor assist services. U.S. Pacific Fleet Forces anchors most dollars at $973 thousand across two awards, creating a tension between volume (Coast Guard) and value (Navy). Defense Logistics Agency Energy and the Army Corps of Engineers round out a four-agency customer base. The portfolio spans navigational services to shipping (10 awards), port and harbor operations (7 awards), and inland water freight transportation (3 awards) under primary NAICS categories.
Activity shows volatility: five awards in 2021, a gap in 2022, one award in 2023, nine in 2024, two in 2025, and one in 2026. The combined potential value of $1.1 million across 27 awards reflects purchase-order-based engagement—small individual contracts executed at need rather than large standing vehicles or IDVs. The company operates 100% as a prime contractor with no subcontract exposure in the source data. Centerline Logistics Corp maintains three named subsidiaries: Harley Marine Services Inc., Pacific Coast Maritime Inc., and Olympic Tug & Barge, Inc., each structured as for-profit organizations, extending operational and asset diversity across the Pacific Northwest maritime market.
