About the company
H & H Marine Services, Inc. is a Port Gibson, Mississippi-based Service-Disabled Veteran-Owned Small Business (SDVOSB) incorporated as a Subchapter S Corporation that has maintained federal contracting eligibility since its registration in SAM.gov in February 2004. The company specializes in comprehensive marine repair and maintenance services supporting the U.S. Army Corps of Engineers' inland waterways infrastructure, flood control operations, and vessel maintenance requirements. H & H Marine Services provides critical expertise in engine and generator overhauls, mechanical repairs, equipment fabrication and installation, pumping station maintenance, and emergency repair services for the Corps' diverse fleet of dredges, survey vessels, barges, and land-based facilities throughout the inland waterways system, particularly in the Vicksburg district and surrounding regions.
H & H Marine Services has secured 24 federal prime contract awards from the U.S. Army Corps of Engineers spanning from August 2021 through September 2025, with a cumulative contract value exceeding $4.6 million. The company's service portfolio encompasses major engine overhauls including work on Caterpillar marine diesel engines (3508, 3516, and C32 models), generator set procurement and repair, pumping station maintenance and rehabilitation, vessel maintenance on Corps vessels such as the M/V Muddy Water and M/V William James, gearbox replacement, crane repairs, winch drum repairs, and emergency mechanical repairs. Contracts have been awarded across multiple Corps district locations, including the Vicksburg Engineering District, Memphis District, and St. Paul Engineering District. The majority of awards have been structured as firm fixed-price purchase orders, with set-aside designations predominantly favoring Service-Disabled Veteran-Owned Small Businesses and Total Small Business set-asides, reflecting the company's qualification as a veteran-owned enterprise. Several contracts, including those for sewage ejection system replacement at Lake Village, Arkansas and generator set procurement from the Memphis District, represent continuation of the contractor's longstanding partnership with the Corps of Engineers. The company's consistent track record of contract awards demonstrates sustained demand for its specialized marine repair capabilities and its ability to support critical federal infrastructure and flood control missions.
