About the company
Brennan Marine Inc., a fourth-generation, family-owned specialty marine contractor based in La Crosse, Wisconsin, operates as a 100% prime contractor delivering vessel maintenance, repair, drydock services, and United States Coast Guard compliance work to the federal government on a full-and-open and total small business set-aside basis. The company is a subsidiary of Brennan Group Inc., also headquartered in La Crosse, and competes across NAICS 336611 (Ship Building and Repairing) and related marine repair PSCs.
Brennan Marine's federal footprint is concentrated almost entirely with the U.S. Army Corps of Engineers, which accounts for 98% of recent awards. The top two customer designations—the Engineering and Inventories District St. Paul (35 awards, $3 million combined potential value) and the broader Department of the Army Corps of Engineers (22 awards, $9.9 million)—together represent 57 of 59 prime awards, with a single award from the Department of Homeland Security US Coast Guard. This concentration reflects Brennan Marine's anchor position on a $7.5 million multiple-award Basic Ordering Agreement with USACE, awarded March 1, 2022, and running through February 28, 2027. Under that BOA, USACE has issued 23 delivery orders spanning March 2022 through December 2025, with values ranging from $6,750 to $546,438.68. Representative work includes a $546,438.68 delivery order (November 2023) for full hull plate replacement, interior and exterior painting, anode and strake rail installation, and barge transport on Barge 786; a $303,022.08 delivery order (November 2022) for bottom hopper rubber seal replacement; and a $111,615.60 delivery order (October 2024) for transport, drydock inspection, hull cleaning and painting, and repair across three barges. An additional 4 task orders under an Indefinite Delivery Contract (W912ES10D0004) contribute $337 thousand to the portfolio. Approximately 68% of delivery orders carry no set-aside designation; the remaining 32% are designated total small business set-asides.
Recent activity has been modest and uneven. The vendor received seven awards in both 2022 and 2023, dropped to three in 2024, rebounded to seven in 2025, and has already received three in 2026. The combined potential value across all 59 awards is $13.4 million, with $5.1 million (38%) obligated to date. With the BOA expiring February 28, 2027, recompete opportunity will emerge across the next twenty-four months as task orders under the current vehicle cycle toward completion. Brennan Marine maintains no recorded subcontract footprint and operates exclusively as a prime contractor on all federal work in the source data. The company's specialized capability set—drydock operations, hull inspection and repair, structural remediation, fuel tank cleaning and certification, spud well and hopper seal replacement, outboard motor and fire detection system installation, marine painting and surface preparation, and USCG Subchapter M compliance work—positions it as USACE's dedicated inland waterway vessel maintenance provider, with performance concentrated at its La Crosse, Wisconsin and La Crescent, Minnesota facilities supporting government-owned watercraft throughout the Mississippi River system and broader inland waterways.
