About the company

Seaward Marine Services, LLC, a foreign-owned maritime services contractor based in Norfolk, Virginia, delivers ship husbandry, underwater hull maintenance, and fleet readiness support to the Department of the Navy as a prime contractor operating predominantly on full-and-open procurements with no set-aside designations. The vendor competes for 99 percent of its work as a prime, with 1,115 of 1,123 total awards reflecting a deep, sustained relationship with Naval Sea Systems Command and Military Sealift Command.

Seaward Marine's capability portfolio centers on underwater hull cleaning and inspection, hull coating application, propeller and shaft seal work, cofferdam installation and removal, barge services, and specialized diving support for surface ships, submarines, and auxiliary vessels. The vendor executes work across the Navy's Atlantic and Pacific fleets, with primary administrative oversight in Norfolk and service delivery at naval shipyards and overseas locations including Joint Base Pearl Harbor Hickam, San Diego, Portsmouth, Sasebo, Bahrain, Singapore, and Guam. Recent representative work includes a $19.28 million hull cleaning delivery order for Naval Sea Systems Command (December 8, 2025), a $21.3 million Pacific Fleet services order (November 1, 2024), a $17.84 million hull cleaning order (December 8, 2025), and a $1.463 million USS IDAHO maintenance order (January 20, 2026). The vendor holds one named subsidiary, Seaward Marine Services, Inc.

Customer concentration sits entirely within the Department of the Navy. Naval Sea Systems Command accounts for 504 awards representing $1.32 billion of the combined potential value across the portfolio—a concentration that dominates both award count (98 percent coverage) and dollars. Military Sealift Command follows with 121 awards and $37.7 million combined potential value. The split between the two Navy components tracks closely: NAVSEA anchors the volume and dollar concentration, while MSC sustains a steady stream of smaller-value delivery orders ($21,500 to $3.7 million) for global sealift maintenance. Outside the Navy, the vendor has executed minimal work with other agencies; 439 additional Department of the Navy awards carry only $660 thousand combined potential value, reflecting residual activity separate from NAVSEA and MSC.

Seaward Marine Services holds two primary indefinite-delivery, indefinite-quantity contracts anchoring its federal footprint. The Naval Sea Systems Command single-award IDIQ, valued at $295.9 million with an ultimate completion date of March 27, 2028 (effective March 28, 2023), has generated 144 task orders and $290.3 million in combined potential value. The Military Sealift Command single-award IDIQ, valued at $24.09 million and running through August 9, 2026 (awarded August 10, 2021), has generated 121 task orders and $37.7 million in combined potential value. The top five parent vehicles across the portfolio account for 569 task orders, with Indefinite Delivery Contract N0002416D4102 generating 144 orders and $290.3 million, and N0002402D4001 generating 216 orders and $48.2 million. Delivery orders are predominantly firm fixed-price or fixed-price with economic price adjustment structures, with performance periods typically spanning one to six months from award date.

Activity has grown year over year—26 awards in 2022 to 53 in 2024, with a slight consolidation to 51 awards in 2025 and 20 awards through April 2026. Eighteen awards with ultimate completion dates in the next twenty-four months carry combined potential value of $50.3 million, representing recompete exposure. The vendor's category concentration reflects its maritime mission: Ship Building and Repairing (313 awards), Other Support Activities for Water Transportation (238 awards), and Commercial and Industrial Machinery and Equipment Repair and Maintenance (174 awards) dominate NAICS representation. PSC coding mirrors this focus, with Maint/Repair/Rebuild of Equipment—Ships, Small Craft, Pontoons, and Floating Docks (426 awards) and Maint/Repair/Rebuild of Equipment—Miscellaneous (317 awards) as primary service codes.

Seaward Marine Services executes a limited subcontractor footprint, appearing as a sub on 8 awards (1 percent of total). Named prime contractors include Lockheed Martin Corporation (multiple waterjet tunnel inspection orders, 2024), East Coast Repair & Fabrication, LLC (USS Omaha and USS Hershel "Woody" Williams ship repair availability work), Phoenix International Holdings, Inc. (diving services for sacrificial anode replacement on USS Little Rock), and Crowley Government Services, Inc. (Cape Starr ship support). The subcontractor role reflects specialized diving and inspection services delivered under larger ship repair and modernization primes rather than a core business posture.

The vendor's twenty-five-year federal contracting history since SAM.gov registration in 2001, combined with its two singular, high-ceiling IDIQ vehicles serving the Navy's global fleet maintenance mission, positions Seaward Marine Services as a critical provider of routine and emergent maritime maintenance. Competitors should expect sustained competition for hull cleaning, inspection, and vessel maintenance delivery orders under the two active Navy IDIQ vehicles, with annual obligation patterns suggesting $40 million to $60 million in annual task order activity and recompete risk concentrated in the next twenty-four months.
