Marine Systems, Inc.

Marine Systems, Inc., doing business as Ewing Marine Systems, supplies marine propulsion and auxiliary equipment, diesel engine components, and emergency repair services to federal maritime agencies as a prime contractor on full-and-open purchase orders. Based in Seattle, Washington, the company is a for-profit organization that has maintained continuous System for Award Management registration since 2001 and competes exclusively in unrestricted federal procurement — none of its awards carry small-business set-asides.

The vendor's capability portfolio centers on turbosuperchargers, diesel engine parts kits, marine generators, emergency diesel engine repairs, raw water pumps, turning gears, and original equipment manufacturer (OEM) certified maintenance and inspection services for federal vessels. Concrete recent work includes a $137,017 firm fixed-price purchase order from the U.S. Coast Guard for an auxiliary generator turbocharger (Part Number 9528223) destined for the USCGC Healy, awarded in February 2027 with delivery to Base Seattle; a $229,528 Coast Guard purchase order for diesel engine and PowerBlade parts kits, awarded in September 2026; a $124,720 Naval Supply Systems Command purchase order for a turbosupercharger, awarded in June 2024 with completion by April 2026; and a $54,091 National Oceanic and Atmospheric Administration purchase order for emergency repairs to the #2 diesel engine aboard the NOAA Ship Fairweather in Ketchikan, Alaska, awarded in May 2025.

Customer concentration is distributed across maritime and naval agencies, with the top five funding entities accounting for 88% of combined potential value. The Department of the Army Corps of Engineers leads in potential value ($10 million from a single award) but represents minimal award volume (one award); the Department of Homeland Security's U.S. Coast Guard anchors activity volume with 47 awards totaling $1.1 million combined potential value, followed by the Department of the Navy's Military Sealift Command (30 awards, $796 thousand), Naval Supply Systems Command (15 awards, $1 million), and the National Oceanic and Atmospheric Administration (25 awards, $438 thousand). Marine Systems operates under two named IDV vehicles: an Indefinite Delivery Contract (DTCG8502D625498) and a Blanket Purchase Agreement (DTCG8503P625905), each carrying one task order in the source data.

Activity history shows volatility in recent years — four awards in 2023, a spike to 23 awards in 2024, then a sharp contraction to three awards each in 2025 and 2026, with one award in 2027 — reflecting the inherently episodic nature of vessel maintenance and parts procurement. Combined potential value across all 236 prime and sub awards stands at $15.2 million, of which $12.5 million (82%) has been obligated. Only two awards face ultimate completion within the next twenty-four months, with combined potential value of $367 thousand, indicating minimal near-term recompete exposure.

Marine Systems subcontracts primarily to Assurance Technology Corp, performing EMD generator engine overhaul work with OEM parts under multiple project references including COMPLEX ACTION and TERFS R&D initiatives, with sub-awards dated August 2024 and March 2024. The vendor's NAICS footprint is heavily concentrated in Ship Building and Repairing (85 awards), Other Engine Equipment Manufacturing (42 awards), and Commercial and Industrial Machinery and Equipment Repair and Maintenance (35 awards), with PSC coding dominated by Non-Nuclear Ship Repair West (37 awards), Miscellaneous Ship and Marine Equipment (23 awards), and Diesel Engines and Components (19 awards).
