About Karl Senner, L.L.C.
Karl Senner, L.L.C., a for-profit limited liability company headquartered in Kenner, Louisiana, manufactures and overhauls marine reduction gears and ship propulsion equipment for federal maritime customers as a prime contractor with no subcontract footprint. The vendor operates under no set-aside restrictions and competes full-and-open across all customer agencies.
Karl Senner's capability portfolio centers on the overhaul, remanufacturing, and supply of Reintjes WVS 234 reduction gears for the Coast Guard's 47-foot motor lifeboat fleet, alongside broader marine gear repair and marine propulsion component manufacturing. Representative work includes a $1.452 million indefinite delivery contract with the Coast Guard (awarded September 2021, running through September 2026) for gear overhaul and supply services; a $600,992.50 definitive contract from the Army Corps of Engineers (awarded December 2025) for overhaul of two Reintjes reduction gear transmissions for the Mississippi River Project Office; a $348,612.20 purchase order from the Army Corps of Engineers (September 2021) for gear overhaul on the M/V William James; and a $189,121 purchase order from Naval Supply Systems Command (September 2021) for gear assembly delivery. All work is performed at Karl Senner's Louisiana facility or at customer sites; the vendor has delivered more than $1.5 million in prime federal contract awards since 2019.
Customer concentration is heavily weighted to maritime and waterway operators. The Department of Homeland Security U.S. Coast Guard dominates both volume and dollars, accounting for 40 awards and $4.6 million in combined potential value (55% of the total portfolio). The top five customer agencies—Coast Guard, Army Corps of Engineers, Naval Sea Systems Command, Naval Supply Systems Command, and NOAA—account for 64% of all awards. The revenue ranking diverges slightly from volume: the Coast Guard leads both metrics, but the Army Corps of Engineers anchors the second-largest dollar position ($1.2 million) on only six awards, reflecting larger individual contract values for vessel gear overhaul work. The vendor holds positions on four Coast Guard indefinite delivery contracts (HSCG4016D53000, 70Z04021D55900B00, HSCG4010D50025, HSCG4010DK50025), with seven task orders placed against the primary IDC totaling $781 thousand.
The award portfolio spans three decades, with 136 total awards recorded since 1996. Activity has been episodic: three awards in 2021, three in 2022, one in 2023, two in 2025, and one in 2026. The combined potential value across all awards is $8.3 million, of which $6.1 million (73%) has been obligated. The vendor's NAICS footprint reflects its specialization: 47 awards fall under Speed Changer, Industrial High-Speed Drive, and Gear Manufacturing (NAICS 333613), with 23 awards in commercial machinery repair and maintenance and 15 in ship building and repairing. The corresponding PSC coding emphasizes marine equipment repair (18 awards), torque converters and speed changers (17 awards), and heat exchangers and steam condensers (11 awards).
