Marianas Gas Corp

Marianas Gas Corp, doing business as Island Equipment Co, is an SBA-certified HUBZone firm and minority-owned, small disadvantaged business based in Hagat, Guam that supplies industrial gases, hazardous waste management, and environmental compliance services to the Department of Defense as a prime contractor across two major indefinite delivery contracts with the Defense Logistics Agency.

The company operates two primary IDIQ vehicles anchoring 90% of recent award activity. The first is a $17.7 million single-award small business set-aside DLA Disposition Services contract (SP450022D0016, running through August 2027) covering hazardous and non-hazardous waste removal, transportation, and disposal—including reactive sludge, PFAS liquids, flammable materials, PCB ballasts, lab packs, and used oil—plus industrial gases and environmental compliance services to military installations in Guam and the broader Pacific. The second is a $7.1 million non-set-aside DLA Energy contract (SPE60121D1514, running through September 2026) for technical nitrogen, liquid nitrogen, and aviator's breathing oxygen supporting Indo-Pacific Command operations. A third vehicle, newly awarded in April 2026, is a $9.0 million non-set-aside DLA contract (running through March 2031) for aerospace energy products—liquid nitrogen and aviator's breathing oxygen—to Middle Eastern locations, representing geographic expansion beyond the Pacific. Across these vehicles, Marianas Gas Corp has executed 278 delivery orders (155 under Disposition Services, 98 under DLA Energy, and 32 under the Navy contract N0060409D0002).

Customer concentration is acute. DLA Energy and DLA Disposition Services account for 90% of award count and 98% of combined potential value ($31.8 million and $29.8 million respectively). The Department of the Navy Bureau of Medicine and Surgery, a smaller but meaningful customer, has placed 49 awards totaling $9.1 million, primarily for medical gas supply to Naval Hospital Guam. The Defense Health Agency and other Navy components round out the portfolio. Recent task orders under the primary vehicles range from $2,000 to $288,000 and are predominantly firm fixed-price, non-set-aside awards, demonstrating the vendor's competitive standing alongside its small business certifications.

Activity has grown sharply—from 33 awards in 2022 to 88 in 2024—and remains elevated at 73 awards in 2025 across a portfolio of 469 total awards since first registration in 2007. Year-to-date 2026 shows 18 awards. The recompete cliff is modest: 23 awards (combined potential value $1.6 million) complete within the next twenty-four months, principally task orders expiring under established vehicles rather than parent contract expirations. The vendor competes predominantly full-and-open rather than under set-asides, despite its HUBZone and small disadvantaged business status—evidence of competitive capability earned through consistent on-time delivery of critical logistics and environmental services to forward-deployed defense installations.

Capability framing reflects the award portfolio precisely: technical gas supply (nitrogen, aviator's breathing oxygen, medical gases), hazardous waste removal and disposal (including PFAS, reactive sludge, flammable liquids, and specialized materials), environmental compliance and remediation, and life support equipment procurement (oxygen breathing apparatus canisters, oxygen candles). Representative named work includes a $169,349 delivery order from DLA Energy (September 2025) for aviator's breathing oxygen, a $288,305 delivery order from DLA Disposition Services (July 2025) for corrosive inorganic acids, a $256,073 delivery order (March 2025) for OBA canisters and oxygen candles, and a $2.1 million purchase order from the Defense Health Agency (July 2025) for medical gas supply to Naval Hospital Guam through September 2030. The vendor is the sole subcontractor identified in the source: a $refill service for fire extinguishers under Amentum Services, Inc. on the PACAF GPMS program (September 2025).

Marianas Gas Corp's posture is characteristic of HUBZone vendors with geographic anchoring—it uses its set-aside certifications selectively (the Disposition Services IDIQ is small business set-aside; the Energy IDIQ and newer Middle East contract are not) and competes primarily on price and performance rather than reserve status. Federal contracting has been continuous since October 2006 registration, with particular intensity in the past three years as it has become DLA's principal provider of hazardous waste logistics and technical gas supply across Guam, Hawaii, and Japan—and, as of 2026, the Middle East theater.
