3MC Mobile & Mechanical Repair LLC

3MC Mobile & Mechanical Repair LLC, a small business limited liability company based in Hilliard, Florida, delivers dockside repair, maintenance, and inspection services for federal maritime vessels exclusively as a prime contractor under total small business set-asides. The vendor operates across NAICS 336611 (Ship Building and Repairing) and PSC codes spanning non-nuclear ship repair, marine equipment maintenance, and transport vessel support, competing entirely on set-aside vehicles and holding no sub-award activity.

The company's customer footprint is highly concentrated in two agencies anchoring 100% of awards. The National Oceanic and Atmospheric Administration leads by potential value at $162.6 million across 23 awards (79% of combined potential value), driven by a $73.8 million multiple-award Fleetwide Dockside and Ship Maintenance IDIQ running through August 2028. The Department of Homeland Security's US Coast Guard ranks second with 42 awards valued at $34.9 million combined potential, underpinned by multiple single-award IDCs for specific vessels including the USCGC James, USCGC Hamilton, USCGC Stone, and USCGC Calhoun. The Department of Transportation's Maritime Administration and the Department of the Navy account for the remaining $7.7 million across ten awards. Award concentration inverts between volume and dollars — Coast Guard issues numerous smaller orders while NOAA's larger delivery orders drive most potential value — reflecting a transactional model where Coast Guard manages vessel-specific IDCs and issues task orders episodically, while NOAA aggregates requirements under a fleetwide multiple-award vehicle.

Recent activity accelerated from 2 awards in 2022 to 16 in 2025, with 8 awards so far in 2026 (as of August 10, 2026). The vendor holds single-award indefinite delivery contracts with the Coast Guard for individual vessels (James, Hamilton, Stone, Diligence, Calhoun) valued between $817,791 and $2.9 million each, all small business set-asides with ultimate completion dates ranging from mid-2025 through mid-2026. Across task orders issued under these IDCs and the NOAA fleetwide vehicle, scope includes air conditioning plant overhaul and grooming, tank valve renewal, potable water system repairs, fire detection upgrades, davit and crane maintenance, steel renewal, HVAC piping repair, propulsion system component overhaul, hydraulic system modification, and specialized inspections (thermographic, ultrasonic, non-destructive examination). Concrete recent examples include a $1.037 million firm fixed-price definitive contract with the Coast Guard for dockside maintenance on the USCGC Seneca (watertight closures, piping, ventilation, thermographic inspections across 27 work items; August 2026), a $2.4 million delivery order with NOAA for dockside repairs on the Thomas Jefferson (September 2024), a $1.42 million Coast Guard delivery order for USCGC Hamilton fourth-quarter maintenance (September 2025), and a $1.2 million NOAA delivery order for repairs on the R/V Bay Hydro II (September 2025).

SCI-reported invoicing on federal service contracts above the $150,000 threshold totaled $20.1 million across FY2022–FY2025, with peak invoicing of $7.8 million in FY2024 and a trailing FY2025 figure of $6.4 million. The vendor delivered roughly 7 FTEs on average across SCI-reportable contracts in recent years (ranging from 5.4 to 8.7 FTEs per fiscal year), reflecting a small direct-labor footprint consistent with its role mobilizing technician-level crews for episodic vessel maintenance windows. On federal services contracts, median government-paid hourly rates centered around $346/hr, with a spectrum from $166/hr at the tenth percentile to $883/hr at the 90th percentile, typical of maritime skilled labor spanning entry technician work through senior supervisory roles. Across SCI-reportable prime contracts, the vendor performed zero percent of hours through subcontractors, maintaining fully internal delivery teams and demonstrating no reliance on sub-network leverage.

3MC competes entirely under total small business set-asides on Coast Guard and NOAA vehicles and holds no parent vehicle memberships on GWACs, GSA Schedules, or government-wide IDIQs. The company registered in SAM.gov in February 2010 and has maintained consistent presence in federal maritime repair since 2016, with recent acceleration in both Coast Guard and NOAA award velocity driven by vessel availability scheduling and fleet readiness cycles at both agencies.
