Brennan Marine Inc.

Brennan Marine Inc. is a fourth-generation, family-owned specialty marine contractor based in La Crosse, Wisconsin, that has been registered to receive federal awards since May 2001. The company operates as a for-profit, Subchapter S corporation and provides comprehensive vessel maintenance, repair, and compliance services to the U.S. Army Corps of Engineers and related federal agencies. With over 100 years of combined experience in marine construction, environmental remediation, and harbor management, Brennan Marine has established itself as a critical vendor supporting the federal government's mission to maintain operational readiness of government-owned watercraft essential to navigation operations and infrastructure maintenance throughout the Mississippi River system and inland waterways.

Brennan Marine Inc. has delivered an extensive portfolio of marine repair and maintenance services through federal contract awards spanning from 2021 through December 2025. The company's past delivery orders and purchase orders, all funded by the U.S. Army Corps of Engineers, demonstrate expertise across multiple specialized service categories including drydock inspections and repairs, hull cleaning and painting, full hull plate replacement, fuel tank cleaning and repairs, structural failure repairs, barge corner knuckle replacements, spud well repairs, hopper seal replacements, installation of marine safety systems such as fire detection systems and magnesium sacrificial anodes, outboard motor installation, vessel transport and docking services, and United States Coast Guard Subchapter M compliance work. Individual delivery order values have ranged from $6,750 to $546,438.68, with recent notable awards including a $50,972.82 delivery order for drydock inspection and repair of the USACE pushboat M/V McNamara (December 2025), a $93,230 delivery order for Barge 773 repair including corner knuckle replacement (November 2025), and a $42,316 delivery order for transport, dry dock inspection, water blasting, and painting of USACE Fuel Barge 9511 (November 2025). While the majority of Brennan Marine's contract awards have been issued without set-aside designations, the company has also received multiple delivery orders and purchase orders designated as total small business set-asides, demonstrating its qualification and participation in small business contracting programs.

Brennan Marine Inc. holds a $7.5 million multiple-award Basic Ordering Agreement (BOA) with the U.S. Army Corps of Engineers, awarded on March 1, 2022, with an ultimate completion date of February 28, 2027. This indefinite delivery vehicle, funded through the Engineering and Inventories District St. Paul office, enables USACE to maintain flexible, priority access to Brennan Marine's specialized marine repair capabilities and dedicated drydock facilities without the need for competitive re-solicitation on individual task orders. The BOA was solicited beginning September 20, 2021, and carries no set-aside designation at the vehicle level. Under this BOA, USACE has issued numerous firm fixed-price delivery orders addressing the full spectrum of vessel maintenance and repair requirements for government-owned watercraft, with performance consistently taking place at Brennan Marine's facility in La Crosse, Wisconsin. The BOA serves as the primary contracting vehicle through which Brennan Marine supports USACE's civil works and emergency response missions, enabling the agency to efficiently address both planned maintenance and urgent repair requirements for its aging vessel fleet operating throughout Wisconsin, Minnesota, and the broader Mississippi River system.
