3MC Mobile & Mechanical Repair LLC

3MC Mobile & Mechanical Repair LLC, headquartered in Hilliard, Florida, is a small-business-set-aside maritime vessel repair and maintenance contractor that operates exclusively as a prime contractor (100% of recent awards) to the federal government, with no sub-award activity. The company delivers dockside repairs, mechanical and system maintenance, and vessel inspections across the federal maritime fleet under NAICS 336611 (Ship Building and Repairing).

Customer concentration is extreme and decision-relevant. The National Oceanic and Atmospheric Administration accounts for $162.5 million (80% of combined potential value) across 23 awards, while the U.S. Coast Guard ranks second with $33.9 million across 41 awards. The Maritime Administration and the Navy contribute $5.3 million and $2.4 million respectively. NOAA's outsized dollar share reflects 3MC's seat on a $73.8 million multiple-award Fleetwide Dockside and Ship Maintenance IDIQ running through August 2028, under which the vendor holds substantial delivery-order volume for research vessel sustainment. The Coast Guard's higher award count but lower dollars reflects a portfolio of smaller single-award indefinite delivery contracts on specific cutters (USCGC Hamilton, James, Stone, Calhoun, Diligence) alongside individual purchase orders for discrete repair tasks.

Recent activity shows steady growth, climbing from two awards in 2022 to sixteen in 2025, with seven awards year-to-date in 2026. The recompete cliff is minimal — only one award totaling $1.1 million reaches ultimate completion within the next twenty-four months, indicating deep contract stability. 3MC's most active parent vehicles are single-award indefinite delivery contracts on specific Coast Guard vessels, with an IDC for USCGC James (WMSL-754) dockside repairs carrying an $817,791 ceiling (January 2026 award) and a $990,819 IDC for USCGC Hamilton maintenance (September 2025 award). Representative work under NOAA includes a $2.4 million FY25 dockside repair delivery order on the NOAA Ship Thomas Jefferson (September 2024, under the Fleetwide IDIQ), a $1.1 million dockside repair order on the R/V Bay Hydro II (September 2025), and a $224,947 emergency starboard Z-drive motor repair on the NOAA Ship Nancy Foster (June 2025). Coast Guard representative awards include a $1.42 million FY25 Q4 maintenance order on USCGC Hamilton (September 2025) and a $1.99 million Q3 FY25 dockside repair order on USCGC James (May 2025).

Across SCI-reportable prime service contracts, 3MC invoiced $13.7 million over FY2022–FY2024 (FY2024 showing $7.8 million across 7.0 FTEs), with government-paid hourly rates spanning a median of $346.37/hr and a 90th percentile reaching $882.83/hr. The vendor performs its own labor exclusively; sub-engagement on prime contracts averaged zero percent. The company registered in SAM.gov in February 2010 and competes entirely under small-business set-asides (the vast majority of awards carry total small-business designations), with no full-and-open prime awards in recent years. All set-aside awards carry firm fixed-price or time-and-materials terms, reflecting the vessel-specific, task-order-driven nature of federal maritime repair demand. Place of performance concentrates in Charleston (North Charleston), South Carolina, with secondary activity in Newport, Rhode Island; Norfolk, Virginia; and other vessel homeports.
