Electronic Marine Systems, Inc.

Electronic Marine Systems, Inc., doing business as Engine Efficiency Associates, supplies specialized marine electronics equipment and repair services to the U.S. Navy's Military Sealift Command and related maritime agencies as a veteran-owned prime contractor (97% of recent awards) and occasional subcontractor on vessel modernization programs. The company manufactures and repairs cargo control consoles, tank level sensors, pressure transmitters, display systems, and associated electronic components for government-owned vessels, with fabrication and service delivery anchored to its Rahway, New Jersey headquarters and ship-repair sites nationwide.

Customer concentration is pronounced and maritime-focused. The Military Sealift Command accounts for 126 awards (35% of the total portfolio) carrying $22 million in combined potential value—roughly 50% of the vendor's total award value. The Defense Logistics Agency's Aviation division places 94 awards worth $640 thousand in aggregate, and the Defense Logistics Agency's Land and Maritime division contributes 36 awards for $149 thousand. The Department of Homeland Security's U.S. Coast Guard has awarded 28 contracts totaling $500 thousand. These four customers alone account for 84% of recent awards. The Department of the Army Corps of Engineers Philadelphia Engineering District, however, anchors the second-largest potential-value concentration: 13 awards carrying $16.7 million, principally via two indefinite delivery contracts—a $500 thousand blanket purchase agreement for engine monitoring systems and marine electronics support services and an $8 million multiple-award IDC for electrical and electronic system support on Corps of Engineers watercraft. This split reflects MSC's high-volume, small-order posture for individual components and repairs, whereas USACE Philadelphia's major IDVs concentrate larger dollars in fewer vehicles.

Work performed includes sole-source and competitive purchases under firm fixed-price terms. Representative prime-contract examples include a $1.44 million MSC purchase order (awarded February 2023) for cargo control software upgrades on T-AO class vessels with ultimate completion in October 2025; a $207 thousand MSC award (September 2022) for console repair and grooming on the USNS Humphreys; a $166 thousand MSC purchase order (March 2024) for cargo console repairs on a T-AO replenishment oiler; and a $209 thousand U.S. Coast Guard purchase order (July 2022) for pressure switches under a total small business set-aside. Recent 2025–2026 awards are smaller and more frequent—tank level sensors, pressure transmitters, cartridge fuses, display units, and ballast control console parts typically valued between $1,500 and $71 thousand. The vendor operates on two GSA Schedule vehicles (GS07F8750D with 9 task orders and GS00F2500A with 1 task order) and holds a notable Indefinite Delivery Contract (W56HZV17D0086) with 10 task orders.

Electronic Marine Systems competes full-and-open; the source identifies no recurring set-aside posture, though the vendor qualifies as veteran-owned and has won individual total small business set-aside awards from the Coast Guard. Activity peaked at 20 awards in 2025 and has grown from 5 awards in 2024, though the portfolio spans 355 awards dating to 1992. Recent repair and upgrade work carries ultimate completion dates into 2025 and 2026, indicating modest near-term recompete exposure; the $1.44 million T-AO software upgrade and certain component orders complete by October 2025.

In its subcontractor role (3% of awards), Electronic Marine Systems delivers low-rate initial production components and systems—battery chargers, pilothouse displays, integrated electrical control switchboards, and condition-based monitoring systems—to Vigor Works LLC, a major vessel-modernization and repair prime, with sub-awards dating to January 2025 and spanning battery chargers, switchboards, and pilothouse display updates for multiple-vessel LRIP programs. The company's capability portfolio is grounded in NAICS 334513 (Other Electronic Component Manufacturing, 67 awards), 334519 (Instruments and Related Products Manufacturing, 47 awards), and 421860 (Ship Building and Repairing, 31 awards), reflecting its focus on marine electronics OEM manufacturing, sensor and transmitter production, and repair services rather than broad defense contracting.
