Multimarine Services, Inc.

Multimarine Services, Inc. supplies marine refrigeration and air-conditioning equipment, parts, and repair services to the U.S. Coast Guard and Department of the Navy as a small business prime contractor, competing across a mix of total small business and full-and-open purchase orders. Headquartered in Baltimore, Maryland, Multimarine is a for-profit corporate entity and an authorized Carrier Transicold dealership with over forty years of maritime HVAC and refrigeration experience.

The vendor's customer base is heavily concentrated in maritime logistics. The Department of Homeland Security US Coast Guard accounts for 57 awards and $1 million in combined potential value—71% of recent award volume—with the Department of the Navy Military Sealift Command adding eleven awards and $400 thousand. These two customers represent 88% of the vendor's combined potential value across all awards. Secondary exposure includes the Department of the Navy United States Fleet Forces Command (Atlantic), the Department of the Army, and NASA Goddard Space Center, but these represent minimal dollar volume relative to the Coast Guard anchor.

Multimarine's scope of work centers on NSN-referenced refrigeration equipment and maritime HVAC systems. Representative recent awards include a $206 thousand firm fixed-price purchase order from the Coast Guard for a refrigeration condenser kit (July 2026), a $79 thousand order for multifaceted chiller and refrigeration plant work on the USCGC Spencer including detailed surveys, servicing, and remedial findings (August 2024), and a $71 thousand survey and repair contract for R-134A seawater-cooled chiller skids on Coast Guard vessels (May 2023). Work is performed at Baltimore-area locations including Curtis Bay Industrial Area and Collegeville, Pennsylvania. The vendor has delivered commissioning and crew training services on specific cutters such as the USCGC Hollyhock and USCGC Sequoia, positioning itself as the OEM-authorized service provider for Carrier marine systems.

NAICS concentration aligns tightly with this refrigeration posture: Plumbing, Heating, and Air-Conditioning Contractors (56 awards) and Commercial and Industrial Machinery and Equipment Repair and Maintenance (25 awards) dominate the portfolio, with Ship Building and Repairing (7 awards) and Air-Conditioning and Warm Air Heating Equipment Manufacturing (6 awards) supporting the shipboard focus. PSC codes mirror the pattern—Maintenance/Repair/Rebuild of Refrigeration, Air Conditioning, and Air Circulating Equipment (20 awards) and Refrigeration and Air Conditioning Components (16 awards) represent the largest shares.

Activity has been sporadic over the past five years—one award in 2020, one in 2022, three in 2023, six in 2024, and one in 2026—with a combined potential value of $1.7 million across 103 total awards since 2000. Only one award faces ultimate completion within the next twenty-four months (the July 2026 condenser kit with a $206 thousand ceiling), suggesting limited recompete exposure in the near term. Multimarine operates as a 100% prime contractor with no subcontract footprint in the source data.
