The W.w. Williams Company, LLC

The W.W. Williams Company, LLC, a for-profit limited liability company based in Dearborn, Michigan, supplies marine diesel engine overhaul, repair, and remanufacturing services to federal maritime agencies as a prime contractor exclusively, holding no subcontractor positions and competing exclusively in full-and-open procurements with no set-aside designations.

The company operates as a child entity of Power Acquisition LLC and concentrates on MTU 60 Series and Detroit Diesel engine maintenance, components supply, and technical services for Coast Guard vessels and naval assets. W.W. Williams specializes in industrial equipment repair, turbocharger and fuel injection assembly work, electronic component repair, and dynamometer testing for marine propulsion systems. Concrete representative work includes a $2,079,579.70 firm fixed price delivery order from the U.S. Coast Guard (September 2024) for overhaul of 18 engines with disassembly reports, a $204,380.71 delivery order (June 2023) for open, inspect, and repair of an industrial fluid cooler, and a $249,950 purchase order from the National Oceanic and Atmospheric Administration (January 2023) for two John Deere counter-rotating marine engines and Twin Disc marine gears.

Customer concentration is extreme. The Department of Homeland Security U.S. Coast Guard accounts for 100 of the vendor's 124 awards (80% of all activity by count) and $61.7 million of $63.4 million in combined potential value (97%). The Department of Commerce National Oceanic and Atmospheric Administration, the Department of the Navy Naval Sea Systems Command, the Department of the Army, and the Department of Justice Bureau of Prisons together account for the remaining 24 awards and roughly $1.7 million in combined potential value. By potential value, Coast Guard work dominates so completely that no secondary customer represents more than 1.1% of the vendor's total pipeline.

W.W. Williams holds three active parent IDIQ vehicles with the Coast Guard, all multiple-award contracts: 70Z04019D55400B00 (41 task orders, $7 million combined potential value, covering MTU engine overhaul through February 2029), 70Z04019D56700B00 (29 task orders, $4.4 million combined potential value), and 70Z04024D51804B00 (8 task orders, $2.3 million combined potential value). The primary vehicle, valued at $26,097,716.36 and running through February 2029, covers the overhaul of MTU 60 Series marine engines and attached Twin Disc reduction gears and has been exercised with 41 delivery orders over the award period. The vendor's entire award footprint sits on Coast Guard IDIQ vehicles; the three named vehicles account for 78 of the 124 total awards.

Activity declined significantly from 2022 forward. The vendor received 22 awards in 2022, 10 in 2023, 18 in 2024, 5 in 2025, and 1 in 2026. Only one award (valued at $246,000) reaches ultimate completion within the next twenty-four months, presenting minimal recompete risk in the near term but signaling a steep decline in annual task order volume across the IDIQ portfolio.

Across four SCI-reportable service contracts captured from FY2022 through FY2024, the vendor reported $2.5 million in invoiced federal service revenue (all prime contracts). The SCI dataset shows 1.3 FTEs delivered in FY2022 (generating $1.5 million) and 0.1 FTEs in FY2023 (generating $1 million); no SCI-reportable service volume was recorded in FY2024. Government-paid hourly rates on prime contracts span a wide range, from a 10th percentile of $460.91/hr for routine labor to a median of $768.42/hr and a 90th percentile reaching $7,668.44/hr for senior technical services such as dynamometer testing and complex troubleshooting. The vendor performed 100% of labor on its SCI-reportable prime contracts; no subcontractor hours are captured in the SCI dataset.

W.W. Williams frequently partners with Rolls-Royce Solutions America Inc., Detroit Diesel Corporation, and Great Lakes Power Service Company as subcontractors for parts supply and specialized engine services, leveraging their original-equipment-manufacturer expertise to fulfill Coast Guard technical requirements. The vendor's narrow specialization in MTU and Detroit Diesel marine propulsion systems and its overwhelming concentration in Coast Guard work create both a sustainable niche for specialized overhaul services and a single-customer dependency that has historically driven high-volume delivery order activity but shows sharp contraction in recent fiscal years.
