Hill Marine Refrigeration Inc.

Hill Marine Refrigeration Inc., a veteran-owned small business based in Mobile, Alabama, provides original equipment manufacturer services and installation work for shipboard refrigeration and air-conditioning systems to federal maritime agencies as a prime contractor, with 100% of its 83 awards in its recent footprint issued as prime purchase orders and no subcontract activity. The vendor competes entirely under full-and-open (no set-aside) and Total Small Business set-aside designations on spot purchases and repair jobs, not under master contract vehicles or IDIQs.

Hill Marine's customer concentration is heavily weighted toward NOAA. The top five funding agencies account for 76% of recent award count and 95% of combined potential value; NOAA's National Oceanic and Atmospheric Administration dominates with 36 awards totaling $1.4 million combined potential value, followed by the Coast Guard (20 awards, $172 thousand), Military Sealift Command (3 awards, $198 thousand), and smaller populations at the Navy's Naval Supply Systems Command and the Army Corps of Engineers. The source notes that Hill Marine's prior contract awards with NOAA and Coast Guard vessels have exceeded $800 thousand cumulatively. Representative work includes a $140.8 thousand Total Small Business purchase order from NOAA in December 2022 for installation of two Carrier refrigeration plants on the NOAA Ship Pisces in Pascagoula, Mississippi (completed February 2023), a $15 thousand Total Small Business repair order for HVAC plant condenser work on the NOAA Ship Gordon Gunter in August 2022 (completed October 2022), a $38.3 thousand follow-on purchase order from NOAA in January 2023 for shipboard modifications to the Pisces to accommodate refrigeration plant installation (completed March 2023), and a $12.9 thousand full-and-open purchase order from Military Sealift Command in April 2026 for OEM refurbishment services on domestic refrigeration and air-conditioning compressors in Norfolk, Virginia (completion September 2026).

Activity has been sparse and episodic — three awards in 2022, one in 2023, none in 2024–2025, and one in 2026 — with only one award ($13 thousand) facing ultimate completion in the next twenty-four months and therefore minimal recompete pressure. Hill Marine's capability footprint centers on HVAC and refrigeration installation, repair, and compressor refurbishment for naval and oceanographic vessels, reflected across NAICS categories spanning plumbing and HVAC contracting (45 awards), ship building and repairing (13 awards), and refrigeration equipment manufacturing (9 awards), with PSC codes emphasizing shipboard refrigeration and air-conditioning equipment maintenance, repair, and rebuild work.
