American Marine Engineering Services, LLC

American Marine Engineering Services, LLC, a small disadvantaged, service-disabled veteran-owned business (SDVOSB) based in St. Petersburg, Florida, provides dockside vessel maintenance, preservation, and repair services to the U.S. Coast Guard as a prime contractor, competing exclusively under the total small business set-aside on firm fixed-price contracts and purchase orders. The vendor operates as a limited liability partnership under NAICS 336611 (Ship Building and Repairing) and PSC codes spanning Non-Nuclear Ship Repair (East), Transport Vessels, and miscellaneous vessel maintenance.

American Marine Engineering Services works exclusively with the Department of Homeland Security's U.S. Coast Guard across all five of its recent federal awards (100% customer concentration), with $6.8 million in combined potential value fully obligated across two contract years. The vendor's capability portfolio centers on post-Ship Life Extension Program (SLEP) vessel availability work, dockside cleaning and preservation of shipboard systems, interior bulkhead preparation and preservation, tank and piping cleaning and inspection, and long-term vessel storage inventory management. Representative work includes a $4.01 million firm fixed-price definitive contract awarded April 8, 2025, for a complete wall-to-wall inventory of contents within sixteen CONEX boxes at Curtis Bay, Baltimore, as part of long-term storage operations for three vessels (completion date May 5, 2027); a $1.18 million contract awarded May 11, 2026, for dockside repairs to the USCGC ESCANABA at Portsmouth, Virginia (completion July 5, 2026); a $1.18 million definitive contract awarded April 14, 2025, for post-SLEP dock-side maintenance on the USCGC Spencer, including seawater heat exchanger cleaning, diesel engine and generator servicing, and steering gear preservation (completion November 16, 2025); and a $333 thousand purchase order for tank and piping cleaning and preservation on CGC Tampa (completion July 19, 2026).

Two awards carry ultimate completion dates within the next twenty-four months, representing $4.3 million in combined potential value exposed to recompete. All work is performed at Portsmouth, Virginia (the Coast Guard's primary homeport for the vessels served) or at Curtis Bay, Maryland, with performance windows concentrated in spring and fall vessel availability periods.
