Curtin Maritime Corp

Curtin Maritime Corp, a Long Beach, California-based for-profit Subchapter S corporation, provides maintenance and construction dredging, ocean-going tug and barge services, and specialized maritime logistics to federal agencies as a prime contractor (68% of recent awards) and subcontractor (32%). The vendor competes predominantly full-and-open, with selective small-business set-aside work on vessel and towing services; recent awards show two Total Small Business set-asides among the broader competitive portfolio.

Curtin Maritime's prime work centers on mechanized dredging operations across domestic ports and waterways, grounded in NAICS 237990 (Other Heavy and Civil Engineering Construction) and PSC Z1KF (Maintenance of Dredging Facilities). Representative recent prime contracts include a $34.3 million definitive contract from the Army Corps of Engineers for Houston Ship Channel dredging (September 2025), a $30.5 million Baltimore Harbor and Channels maintenance dredging contract with the Army Corps of Engineers (October 2024), a $28.6 million Oakland Inner and Outer Harbor maintenance dredging award from the Army Corps of Engineers San Francisco District (June 2024), and a $22.8 million Baltimore Harbor dredging award (November 2025). Curtin Maritime also holds a $13.8 million indefinite-delivery contract with Naval Supply Systems Command for San Clemente Island Barge Services (Total Small Business set-aside, October 2022 through September 2027) and a zero-dollar multiple-award indefinite-delivery contract with the Air Force for Voluntary Intermodal Sealift Agreement (VISA) contingency services effective October 2024 through September 2034. The vendor is the recipient of a cooperative agreement with the Maritime Administration (CFDA program not specified in source) for hybrid dredge and electric-assist tug design and demonstration, awarded December 2023 with ultimate completion January 2027.

Customer concentration tracks heavily to the Army Corps of Engineers and its district-level commands. The top five customer agencies by funding account for 73% of combined potential value: the Army Corps of Engineers San Francisco District leads with 13 awards ($79.8 million combined potential value), followed by the Army Corps of Engineers Jacksonville District (3 awards, $69.7 million), the Department of the Army broadly (4 awards, $64.6 million), the Army Corps of Engineers Baltimore District (2 awards, $53.3 million), and the Army Corps of Engineers Los Angeles District (7 awards, $36.6 million). By award count, the Naval Air Warfare Center tops the list with 18 awards ($5 million combined potential value), but these represent lower-value vehicle charters and logistics tasks; Military Sealift Command follows with 14 awards ($13.9 million). The Army Corps of Engineers and its districts dominate both high-value dredging work and dollar concentration.

Activity has accelerated significantly. Curtin Maritime recorded three awards in 2022, growing to 14 in 2023, 17 in 2024, and 22 in 2025; six awards have been placed through August 2026. Six awards with ultimate completion dates in the next twenty-four months carry combined potential value of $35.2 million and face recompete exposure. The vendor's sub work comprises roughly one-third of recent awards and centers on tug and barge operations, vessel support, and maritime logistics. Named prime contractors include Systems Application & Technologies Inc. (multiple TARGETS Operations & Maintenance contracts for tug and barge support and Gray Flag tug services), BAE Systems Maritime Solutions San Diego Inc. (USS Kansas City and DDG 125 direct subcontract costs), Manson Construction Co (towage services), Oasis Systems LLC (operations and sustainment labor services), and Marine Ventures International Inc. (charter vessel services for sub-sea cable installation). Curtin Maritime also subcontracted dredging services to Seaward Marine Corporation (a veteran-owned small business) and scow monitoring to Adiss Inc. on the $6.664 million Military Ocean Terminal Sunny Point maintenance dredging contract (June 2025).

The vendor's IDIQ footprint is limited by source coverage; the two largest vehicles listed are Unmanned Maritime Systems Support (2 task orders) and Information Analysis Center Multiple-Award Contract (1 task order), neither revealing substantial order velocity. The Naval Supply Systems Command San Clemente Island Barge Services IDC and the VISA contingency contract represent the vendor's standing availability for maritime logistics rather than established task-order streams. Combined obligated dollars across all awards reach $395.4 million, representing 95% of combined potential value, signaling strong execution momentum. Curtin Maritime's award profile spans 24 distinct federal agencies, with defense and Army civil works accounting for the vast majority of volume and dollar concentration.
